This floor plan can be completely done in under
20 minutes, and I'm going to show you how to do it STEP-BY-STEP. We'll begin with the floor plan.
For this exercise I'll just use a simple one from freepik that I edited. If you want to follow
along in this video, you can take a screenshot of this now. If you ever need a more elaborate
plan, a nice resource is floorplans.com where you can enter here the properties of the house
and it will show you the best matches in their database. If you wanted to create your own you
can use any of the tools available by Googling “floor plan designer”. Go to top view and drag
and drop the floor plan image to blender. On the data panel turn Opacity on and change this to
around 0.4, this way we can always see the grid and the axes. If for some reason your plan was at
an angle, just select it and press Alt+R to clear the rotation. To begin modeling, we need to have
our plan at real scale, so add a plane and resize it to the dimensions indicated in the floor plan.
Here we've got a rather small apartment of 6 x 5 m so we change our plane´s dimensions. Then we
apply the scale by pressing ctrl+a>>Scale. To make our lives easier, we want our floor plan to
start in the world origin and that will make it easier to see our dimensions using the grid.
To do that select the plane and tab into edit mode. Select this vertex then shift+s>>Cursor
to Selected. Tab out to object mode, right click>>Set Origin>>Origin to 3D Cursor. Now press
alt+g to reset the location. Tab into edit mode, select everything with ‘a’ then ‘x’>>Only Faces to
delete the face. Tab out and now scale the floor plan to match the size. Now we'll start making the
walls. Select your plane, tab into Edit Mode and the easiest way is to start only with one vertex
so delete these three and we'll be extruding these vertex to trace all of the walls. Our first wall
is 1.1 m in the X direction so with the vertex selected ‘e’ to extrude ‘x’ to constraint to the
X-axis then you can type the distance you want to move it. My scene units are in centimeters, which
you could change here, so I'll just extrude it ‘x’ and type 110, enter. You'll note that the new
vertex is in the left side of this vertical wall. I did this on purpose to make the point that
you'll ideally want to place a vertex on either side of the wall's thickness. The reason for this
is that you can decide towards which direction the wall will extrude. We can worry about this later
but just keep that in mind. Extrude the vertex again, 270, enter, and again we have a situation
where the thickness of the wall is not being considered in the plan. These little things happen
all the time especially if you download plans from the Internet. It's not a huge deal but you do need
to know what to do in these cases. For this one I'll just move the vertex in X 15 cm which is the
standard thickness of the walls where I live. And now we encounter a new problem which is that these
floor plan’s walls are thinner than the ones that I would use. Different countries use different
materials so this is normal. I'll turn on SnapTo Increment and we mark this check box that says
Absolute Grid Snap. Then I'll just Grab this in X and snap the vertex to the nearest 10 cm mark as
I want to respect the total area of the project. Next I'll extrude this and Y, then this in X,
and bring this back a little bit. Extrude this in Y and continue doing this to trace the outer
perimeter always leaving a vertex every time there's a wall intersection. Once you're done,
select the last two vertices and press F to make that edge. You can turn on the Edge Length overlay
if you want to double check your measurements. Now let's extrude the inner walls. Select this vertex,
Extrude in Y 170. Now select these two and make an edge. You don't only want to extrude this one
all the way as it will leave these two edges disconnected from each other. Now extrude this
one, there is no measurement here, so we snap to the closest 10 cm. You’ll note that these two
edges are now connected as should be. For the next one we actually moved this wall a little bit so
this measurement of 2.2 m is now off. To ensure that we extrude the right amount, a nice trick
is using the Base Point function. Extrude this vertex in X then press ‘b’ for base Point, click
on the vertex and then click on this vertex and now you'll see that both edges have the exact same
length. We can do the same thing here Extrude in Y, ‘b’, click, click and we guarantee now that all
of these vertices are sitting on the exact same line. Now in a previous step we extruded this wall
all the way here, so now these two edges are not connected. I would like to say that I did that on
purpose but I actually did forget, which is great because now I can show you how to fix it. The
fastest way is to subdivide this edge with ctrl+r, click and now you'll see that this edge has been
divided in two segments. Select this vertex, shift+left-click to select this other one, ‘m’ to
merge, At Last, because we want to merge both at this point. And now if I select this vertex and I
move it, you'll see that both edges are connected. We make this final edge with ‘f’ and we're done
with the outline. This is a simple process and we're using a small floor plan for this exercise
but you would do this exact same thing for any floor plan of any size. Remember to save your
work with ctrl+s every now and then. In fact, turn on Autosave in Edit>>Preferences>>Save and
Load>>Autosave. And you can specify here the interval between saves. Now when blender crashes
– and it probably will – if you didn't save you can press window+r and type %temp%, Okay. This
will open the temporary folder and here you can search for the name of your file in this case it's
“floorPlanRec” and then just open the most recent one, and this might actually save you a bunch
of time. Now in edit mode, select all with ‘a’, Extrude in Z and then type whatever height you
want. Here the standard is 2.3 m so 230 and we have our walls. I'm going to switch off the
Snapping for now. Now this step is important, we need to make sure that the orientation of the
faces is correct, so turn the Face Orientation overlay on. Blue is the front and red is the back
of the faces. If the default red color bothers your eyes go to Edit>>Preferences>>Themes>>3D
Viewport and scroll down until you find Face Orientation Back. Here you can select any
color at all but I do think that red is kind of intuitive so I just leave it in red and
change the saturation to a point where I find it easy on the eyes. Now we need to make sure that
all of the outer walls are of the same color, preferably blue. We have one red wall here
so click on Face Select mode or press 3 on your keyboard, not the number pad. Select the
face and press shift+n to Recalculate Normals. It should change orientation but if it doesn't
expand this and click on this check box. The next thing is to make sure that the inner walls are
oriented in a way that the red color is facing the direction of the wall thickness. We want this
wall to extrude to this direction, so this side should be red. With the face selected, shift+n,
Inside and now this wall will extrude towards the correct direction. These seem to be correct. This
one seems to be correct. This one should extrude towards the kitchen so shift+n, Inside. And these
seem to be okay as well. At this point you could adjust the exact position of the faces taking into
account the thickness of the walls. Lastly make sure that whenever there are walls that have more
than one segment like this one that has three, or this one that has two, that all of the segments
have the same orientation. If you don't do this the walls will be deformed once they are extruded.
Now that all of the faces are correct we can turn the Face Orientation overlay off. Now go to Vertex
Select mode, select all of these vertices,shift+d to duplicate, right-click to cancel the move, ‘p’
to Separate>>Selection. This new mesh will be our floor. Now with that mesh selected, shift+d
and duplicate that again, and right-click to cancel the move. We'll rename this new mesh to
“Background”. We'll rename this one “Walls” and this final one “Floor”. Now select the Floor and
if you ever have trouble selecting things that are overlapping press alt+left-click and select the
object you need from this menu, which is another reason why you should name your meshes. We'll
select the Floor, tab into Edit mode, we'll press ‘/’ on the number pad to isolate this mesh,
and now we make all of the Faces by selecting the vertices and pressing ‘f’. I recommend you do
a face per room, this way you can add different floor materials to the different rooms. If you
just wanted to use one material for everything, you could delete all of the inner vertices then
select everything and make a large face. Now ‘/’ to show everything again, Tab out to Object mode,
now select the Background and press ‘/’ to isolate that. This will be a large plane around the house
so that it doesn't seem to be floating in space. In Edit mode, select the outer perimeter, Extrude
with ‘e’ press ‘s’ and scale it up. We don't need these vertices so we can just go ahead and delete
them. The idea is to have an opening where the floor is now to prevent Z-fighting between the
background and the floor. We want this to be a square or rectangle so we just need to move this
vertex to this corner. Again we'll be using Base Point so select the vertex, ‘g’ to grab ‘y’ to
constrain to the Y axis, ‘b’, click, click. Then again, Grab, now ‘x’, ‘b’, click, click. Now if
we ever need to make this bigger, we just select the outer perimeter by pressing alt+left-click and
scale it up or down. Now let's add a material and call it “Background”. I like using a warm gray
tone to add a little bit more contrast with the walls. Now press ‘/’ again to reveal everything.
Select the walls and we're going to add a Solidify modifier. Make sure that the scale of your walls
is 1. If it's not, just select it press ctrl+a and apply the Scale. Now here in the modifier, change
the thickness to whatever you need. Here as I've mentioned, it's 15 cm. Change the mode from Simple
to Complex and our walls are done. If you see the model in some angles you might find it difficult
to work in solid mode so you can always press ‘z’ and go to wireframe mode. And if you don't want
to be able to see through the walls, you can press alt+z to toggle the X-ray mode. To add windows
and doors we'll enable the “Archimesh” add-on. It appears here on the Create Tab and remember that
you can hide and show this panel by pressing ‘n’. You'll note that there's an option to make rooms
here, but the workflow is extremely frustrating and I don't recommend anyone to use it. The
doors and windows however are actually pretty useful and we're going to be using those. We're
going to start with the doors. Make sure that your 3D cursor is on the floor plane by pressing
shift and right-clicking on the plane. This will ensure that the doors are created on the plane and
not flying around. Now select the Floor and press ‘h’ to hide it so that we can see the floor plan.
You can also show and hide things in the outliner by clicking on these eyes. Now you can see the
floor plan to know where the doors go. Here in top view let's add our first door. Click on here
and the door will be added at the position of the 3D cursor. This will be our main entrance so we
can change the Open Side from Right Open to Both Sides. You can also change the model of the door
and its handles. Once you're happy with your door, go back to top view and to move the door we need
to select the Empty that is created with it, and now we can move the door into position. Now you'll
see that the door's properties are no longer displayed in the Archimesh panel so we need to
select the door again to show them. Since the door is now inside the wall and we cannot see it, we
can go to wireframe mode with the X-ray mode on. You need to select the frame of the door to show
the door's properties. Change the frame width to match the floor plan and here you can change any
other properties like the height, the thickness, or the size of the frame. While doing this process
I often change between Solid and Wireframe modes and toggling X-ray on and off so it's a good idea
to memorize those hotkeys. Now we select this shape. Make sure that it's called “CTRL_Hole”
and this is going to be your Boolean to cut the hole from the walls. I find it that when I'm
working with Booleans, Blender crashes more often, so again, remember to save your work. Now one
of our viewers in the previous video @NickTriccc commented to use a Boolean collection. That was
a great tip so we're going to do that. With the shape selected, ‘m’ to move, New Collection and
we're going to call it “Booleans”. Now select your walls add a Boolean modifier, make sure
Difference is highlighted, change Operand Type from Object to Collection, and here select the
Booleans collection that we created. Now select each door independently and rotate it to indicate
that the doors open towards the inside of the house. Now one more thing to note is that if you
change any of the properties of the door like so, everything about the door resets including the
Boolean. This is really not a big deal, just select the shape and move it again to the Booleans
collection. Let's do one more, we add a door, we're going to place it here so we need to rotate
it by 90°. We move it into position, change the width to match the plan. I'll leave the width in
0.65 which is an easy number to remember and I can use this same number for the rest of the doors. I
want to change this to Left Open to match the plan and open the door a little bit. Now we select the
shape, move it to Booleans, and that door is done. Here we can see that it's counterintuitive to open
the door in this way, so we can just go ahead and select it, change the Open Side to Right Open and
move this shape to the Booleans collection again. We open the door and this feels more natural so
we've actually made the plan better. Let's quickly add the rest of the doors. I also noted that the
door sizes in the plan are not exactly the same in every room but it will look better if they are
so I will just live the width of every door at 0.65. I also changed the Open Side and position of
this door. For the windows it's a similar process. Place the 3D cursor at a height that you think is
reasonable; we can always change the height of the windows later so we can just eyeball it for now.
You have both Rail and Panel windows and I always use rail windows because I like them better. Note
again that you need to select this part of the window to show its properties. You can add blinds
to the window. You can also remove the sil, this part. You can remove these handles if you don't
like them, and you can also remove this external frame. I always leave this on because this way
I can easily know that this side goes outside of the house. I'll change the height here to 0.7 and
I'll move the window into position. We change the width to match the plan. We select its control
hole and move it to the Booleans collection. You can open and close either side of the window.
They have a constraint on the axis but not on the position so just be careful not to go beyond
the frame. There is no window in the bathroom, so I'm just going to go ahead and add one. Let's
add the other three windows and remember to rotate these two windows by 180°. There's a trick here
that might save you a little bit of time. We have not applied the Boolean modifier to any of
these three Windows. There's a way to apply all of the modifiers at the same time. If you select
one of these you can see the name of the object here. If we go to Select>>Select Pattern and type
“ctrl_hole*” and then press Enter, you'll see that all of the control holes are selected. Now you
can just press ‘m’ and move all of them at the same time to the Booleans collection. It doesn't
really matter that we had already moved some of them because it will just move them again to the
same collection now we just check that everything is working properly and once we're happy we can
move on to furnishing the house. Press alt+h to unhide the floor so that when we drag and drop our
furniture it will snap to the floor plane. But now we cannot see the floor plan and we need it so
select it and again we can use our alt+left-click trick. It appears as empty because we just dragged
and dropped the image at the beginning of the tutorial. And now move it up in Z a little bit,
we just need to be able to see it. Furnishing is really fun and quite fast once you've set up your
asset Library. If you’re just getting started and don't have any furniture models, I really suggest
you don't try to model everything yourself, it will take you days. Here you'll really need
to spend either money or time and money comes back time doesn't. The websites that I use to
get my assets are Poliigon which has the most photo realistic assets. They also have an add-on
that lets you get the assets directly in blender. These are I'm going to say the best assets to make
scenes like these. They are extremely high quality and they've got lots of assets. The other one is
CG Trader. This one has mostly good assets and you can even download some of these for free.
The free assets are in general actually pretty good. If you do decide to use the paid assets the
typical price range goes from $2 to $15 bucks per asset. You can also use Blend Swap which is
free and its assets are under the Creative Commons license. The quality of the assets that
you will find ranges from unusable to pretty good. And if you're just starting your collection, I
actually made a Starter Kit that has furnishings for the most common rooms in a house. They're all
designed with the same nordic style so that they look good together. Also I've made them low poly
with some of them having modifiers to keep your working file light and responsive but the renders
high quality. All of the materials are procedural to avoid working with external texture files and
they have been done with as few nodes as necessary to look good while also being lightning fast. Of
course they are at real scale with common sizes found in real life. Another neat thing is that I
made modular couches closets and kitchen cabinets so that you can use this same asset system for
rooms of any different size. In all it's over 40 assets and I've priced it at only $15 bucks
to get you started so yeah go ahead and get it, the link's in the description. Now any way you
choose you'll need to add your assets to your library. I'll leave a card at the end to this
video that goes into the details of the asset library but the 30 second version is you go to
Edit>>Preferences>>File Paths, you click on the ‘+’ sign to add a new library, it will ask you
for a location where you will store the asset library. Once you're in your folder click on Add
Asset Library and you'll see that it's been added here. If I go to the asset Library panel and
click on this drop down, you'll see that the newly created asset library is already here. If
I select it, it's empty because I have not added anything. Now every file that is in this folder
will be checked for assets and any asset that it finds it will add to the library. So when you
download your assets from any of the websites you can add different files to that folder or you can
just have one file with several models. If you do decide to download my starter kit you would just
copy it and paste it on your asset Library folder. Everything has already been marked as asset so you
don't need to do anything else once it's in the folder you can just go back to your model, refresh
the library, and everything is already here. I'm going to use these assets to continue showing you
how to furnish the house but you can use any model that you have downloaded and it's already in your
asset Library. Let's begin with bedroom there's a bed here so we can either look for the bed here or
we can search for “bed”. We'll drag and drop this here and this is yet another reason why I like to
make floor plans in 3D like this. I really like to download stuff from the internet and a lot of the
times I find that these schematics use sizes that don't really match with real life things, so once
I add one of the models I can now know that all of this is not going to be possible, so I'm going
to put the bed in the corner and instead of two nightstands I'm only going to use one, so I search
here for “nightstand” and I'll drag and drop this one. Place it in its position, and I can already
see that this is going to be the same thing. If I search for closet and drag and drop this one
rotate 90°, I can of course see that this doesn't fit, so I can start making some decisions about
this. Instead of this couch I'm just going to move this closet to that position and this is actually
a usable room with real scale Furnishings. I can even add a rug. I'm going to use the Rug Oval S,
‘s’ is for small, and I'm just going to place it there. Rotate and we're done with the room. Next
let's do the kitchen. I'm going to start with the stove, rotate 90, and I'm going to place it here.
Again we can see that there's no room for all of this furniture. Let's add a sink, I'm going to use
a Kitchen Sink S for small. Rotate 90 and place it here. Now for the kitchen sink, I actually gave
it a little bit of room to the sides so in this case I can just edit it. Tab into edit mode, ‘1’
for vertical selection, alt+z for X-ray mode and I'm just going to select all of these vertices
and scale in Y. I just move it back in place and that's the kitchen. I'm going to add a table.
Now tables really come in all sizes so this one is okay if you scale it down. Now if you scale it
down just like this it will completely shrink, so press ‘s’ then shift+z so that it doesn't scale
on the Z axis because you do need to keep the height of the table at around 75 cm. Now we add
a couple of chairs, rotate 90 minus, and here we can start seeing that four chairs might be too
much for this tiny kitchen, so for this reason I'm actually just going to leave two chairs, and
I'm going to move everything a little bit to the left. Now since we only have room for two chairs
I'm just going to change this table to a square one. This one's rectangular so I'm just going
to tab in, I'm going to turn off the Edge Length overlay. Alt+z and I'm just going to move this
a little bit 15 cm. This in X minus 15 cm. I'm also going to scale it down a little bit so ‘s’,
shift+z scale it down. And I'm going to place it next to the wall so that there's more room to walk
here. Move the chairs. Now let's add a sideboard as there's really no room to store things here.
We rotate it 90 minus. Now this sideboard is kind of big for the kitchen. I've made them low poly
so that they're actually easy to edit in case it was necessary. We need to move the feet,
remove these vertices, remove this handle, remove these vertices, and make a face here. And
now we've cleared a little bit of room for the couch. Now this couch is too big so I'm going to
delete that and I'm just probably going to add a coffee table. Now one thing to note with assets
you could scale them to fit whatever space you wanted, the thing is that its proportions will be
modified so if you want to do that sort of thing, I recommend you Tab into edit mode X-ray mode and
then move the vertices. This way the proportions are kept and the model doesn't get deformed
because that's actually going to be noticeable in the renders. I'm going to add a small rug here.
For this living area I'm going to add a couch, and again there's no room for the couch so
I'm just going to add a one-seater couch, rotate 90 minus, place it here. Probably also not
going to add a console here. I'm just going to add a chair, rotate and remember rotate minus is
counterclockwise and rotate positive is clockwise so, this is minus 90. And maybe a coffee table.
I'm going to move the couch to the corner and I'm going to add a Rug Oval. Now because I dragged
and dropped the rug on the table and that's why it looks like this so to fix that we can
just press ‘n’ to show this panel, go to Item, and the Location Z we just zero that. Now the
bathroom, toilet drag and drop it here, rotate 90 and again it doesn't fit here so I'm just going
to rotate this 90° in this direction. I'm actually going to go to Wireframe to see the orientation
of this one, it's the other way around so rotate 180 and I'm going to put this one in the corner.
I'm also going to move this window to the left now I'm going to add a sink, rotate 90 minus, place it
here. And shower, rotate 180 and I'm just going to place it here. Let's see if this works. I'm just
going to add a glass wall here to separate the shower. And we've actually made magic with this
tiny bathroom. Finally let's do this foyer area. I'm just going to add a closet here, in fact I'm
just going to duplicate this sideboard and I'm going to place it here. I'm going to add a coffee
table here, and I'm going to add a rug here. Once you're happy with your Furnishings we can make
this panel smaller as we don't need it anymore and we can also hide the floor plan. I'm going to
go to Material Preview, select the floor add a new material slot. I've included three materials in
the starter kit. I'm just going to add this one, the BeigeTiles. And if you ever want to change
the scale of the material you go to Shading and in all of the materials I've highlighted one of
the nodes. You can change this value to change the scale to your liking. I think something like this
looks good so I'm just going to leave it at 3, and I'm going to go back to my Layout workspace.
Now for the lighting there are a few options but I will always use one of these two. The fastest
to set up and render and in fact I think this is the one that looks best is just adding an area
lamp. I'm going to move it up and I'm going to go to my rendered view I'm going to place the
lamp close to the center of the house and make it quite large. I'm going to increase the power to
300. I just noted that my doors were closed so I'm going to open this. This one's looking the other
way so rotate 180. And change the power of the lamp until you find something that looks good. One
trick you can use to find a good lighting is go to the Render Properties and scroll down to Color
Management. Change the view transform to False Color and this shows you something like a light
heat map. If I go back to my light properties I'm going to increase this to 2,000 to show you.
You don't want to have anything completely red, that's overexposed and it's going to look too
white in the camera so we can just lower this to 500, and this aqua color is underexposed so we
might want to increase that a little bit. In fact I could increase this to 800 and this looks good.
You want to have orange in the places that are whiter and more lit so now we go back to render
properties, scroll down and change this back to AgX. And I think this looks pretty good. I like
using this lighting not only because it's really fast to set up but it also highlights the inside
of the house and darkens the outside a little bit which is actually good because you want to focus
on the inside and not on the walls. You can even emphasize that effect by scaling down the lamp.
You can adjust the height and the power of the lamp to get the exact effect that you want. One
final trick here to make it look a little bit more cozy is, with the light selected, you go to the
shading workspace and click on Use Nodes. Shift+a and type “black” until you'll find this node.
Select it and connect the Color to the Emission. I'm going to go here to Rendered View. Now we'll
change the temperature to 5,000 and of course you can change the temperature to whatever you like,
the lower the temperature the warmer the lights, and the higher the temperature the colder it is.
To me 5,000 is the sweet spot. The second way is using HDRIs which you can download from Poly
Haven. Hover on Assets, click on HDRIs and since the floor plan is inside the house you can go here
to indoor and find one you like. And in fact I suggest you download several of them and just try
different ones. When you find one that you like, click on it and you can download it here. For
lighting you usually don't need more than 2K. Keep in mind that the resolution of the HDRI really
affects the render times. The only situation where I would use 16K is if I want to make a render that
looks through the window and then I want something outside of the window to look at. In that case
then yeah, by all means, download the 16K. If you're using it for lighting only, 2K is more than
enough. Download these to a location that is easy to find. Back in Blender I'm going to delete
the lamp. Go to the Shading workspace and in this drop-down change from Object to World.
Shift+a and type “env”. Click on Environment Texture and connect the Color to the background.
Blender uses this magenta-purple color when it has not found the texture, we haven't selected
it so it defaults to this color. Click on Open and then navigate to the folder where you stored
your HDRIs. I have a bookmark because I used the default Blender folder and this one is impossible
to find so click on here to bookmark. Now select the HDRI you want to use and click on Open Image.
You can increase the strength of the HDRI. Try out several HDRIs and use the one that works best for
your project. And now for the moment of truth and the happiest moment: the rendering. Go to top
view and press ctrl+alt+0 on the numbers pad to set the current view to the camera. Now select
the camera and center it on your model. You can go to Viewport Display>>Composition Guides and click
on “Thirds” to help you center it correctly. ‘G’, ‘z’, ‘z’ to move the camera on its local axis
allows you to pull it away or towards the model. Go to render properties. Cycles is really the way
to go for these renders. Now render samples, this will depend on a couple of things particularly
if you're using the rugs from the starter kit. These have hair particles so if you're going
to use them you might want to leave the samples between 128 and 256. If you delete the rugs or if
you turn off the particle systems in the render, then you can really go as low as 16 samples
because the Denoiser that's included in blender does a fantastic job. So, let's render with 128
samples. 128 samples took 48 seconds. Note that I'm rendering in 4k. I'm going to change this to
slot 2, turn this down to 32 and render again. It took 23 seconds. So, this is 32, this is
128, 32, 128. And really the only place where you notice is on the rugs. The rest of the house
looks pretty much exactly the same. I'm going to do one final render with 16 samples. This one took
18 seconds and you can really see the difference in the rugs. So, 128, 32, 16. So if you don't use
the rugs, you can really use low samples and save a bunch of time in rendering especially if
you're going to do an animation. That's it for today's video. If you watched all the way to
