Sims 4 Building How-To's: advanced building techniques

Once you are comfortable with basic building, why not try your hand at a few more advanced building techniques.

Split Levels and Lofts

Different levels in a build can be an interesting feature and are not too hard to do.

To make a split level or a sunken room, the rest of the house needs to be on a foundation, so let's start with building a rectangle room and lifting it up with a foundation. Now divide this into two rooms with a wall. Once you have two rooms, you need to use the sledgehammer tool and remove the floor from one room. This room will be the lower room. At this point, if we remove even one piece of wall to add stairs down to this lower level, it will no longer be seen as a room and the ceiling will be removed. Instead, we will replace some or all of the room with a fence.

Now we can decorate both rooms how we like. The lower room will not have a floor, so you will need to choose a floor covering and drag it out over the area. Note that if you move the house later, the flooring will stay behind as it is not really part of the room. The default foundation has a ridge around the top, so you may want to select a different foundation type to get a smooth wall in the lower room. Add stairs to the upper level. You can add windows to the sunken room, but they can only be placed on the wall area and not the lower foundation part of the wall. Doors cannot be placed in the foundation part of the walls, so entry to the sunken room has to be via stairs.

The sunken room can be anywhere you want in the house. Simply build a room where ever it needs to be and remove the floor from that room and continue in the same way as before. Remember not to remove the wall, but replace it with a fennce.

Lofts

Lofts are similar to split levels, but don't need to be on a foundation and are usually two storeys high.

Let's build a simple one bedroom loft to learn the basics. Start with a rectangle room and build a second level the same size. We need to divide the upper room in two but instead of just adding a wall straight from one side to the other, we will also have a cut-out for the stairs. If the walls are the short walls, this cut-out needs to be three squares.

Replace the dividing wall upstairs with a fence and then remove the floor from the room that includes the little bit for the stair well.

Add the stairs up to the loft. Remember to put the stairs through the bit of fence at the top. If you remove the fence the room area with no floor will no longer be seen as a room and the ceiling will be removed.

You can now add doors and windows downstairs and decorate as you wish.

Sims 4 Building How-To's:

Dormer Windows

Dormer windows are usually associated with attic rooms. They let light into an otherwise dark area enclosed within the roof of a house. Let's take a closer look at the parts needed to build a basic dormer window.

Start by building the lower floor of the house. This can be any size, but ideally, it should be at least three squares wide and at least nine squares deep. Go up a level and build another room the length of the first room, but starting three squares in from the front and ending three squares from the back. This room can end more than three spaces from the back if you don't want back dormer windows, but it needs to be at least three squares deep.

Sims 4 Building How-To's: dormer

Now build a small room the size of the dormer onto the front of the upper room. This can be any width and can come out one, two or three squares. How far you come out from the main room will determine how much space you will have for the front window. Remove the wall between the dormer room and the main room. Here I have built a few different sized dormers to show how they change the look.

Sims 4 Building How-To's: gable roof on the upper level. tutorial.

Add a gable roof on the upper level but not out over the dormers. Make it so the gable ends are at the sides of the house. Now pick the half gable tool and place it on the lower floor at the front with the slope of the roof matching the roof on the upper floor.

Sims 4 Building How-To's: continuing our dormer windows

With this piece of roof selected, grab the arrow handle and drag it to the other end of the house. Don't worry about going through the dormers, when you look at that level, the rooms will have no roof pieces through them. Grab a full gable roof piece and place it on top of each dormer so that the gable end is facing the front. On the narrow dormers, you will need to pull the roof in to fit the smaller size. On the dormers that come out further, you will need to grab the back arrow handle and extend the gable roof section so that it goes into the main section of roof and you can no longer see the back end.

Click to Enlarge. make sure the dormer roof pieces extend into the main part of the roof

Now you can add windows to the dormers. How wide they are and how far out they come will limit what windows you can use, but using the moveobjects cheat will give you more choices.

For wider dormers, consider using a very low half gable roof for a different look.

Sims 4 Building How-To's: dormers

You don't have to have dormers on both front and back of the house. It could be finished with just a full length of half gable to match the front or the roof might not extend as low as it does at the front. You may even go for a combination of the two.

Sims 4 Building How-To's: making a loft

Note that although I have said that the areas where the half gables go need to be three squares deep, they can be smaller or larger, but matching up roof sections becomes a lot harder when the size is changed.

i just want to share a little of my experience playing the sims 4, i've tried this once on my tudor style house, but unlike in the sims 3, the surrounding walls in gable and half gable roof of the sims 4 is "undeletable". so in case of dormer windows, those surrounding roof walls are blocking the access to the dormer. maybe it's only me and my base game, is there anybody here suffer the same?

berli, I just had a play and was able to recreate your problem. I found that you need to have a ceiling in the dormer area before you add the gable. Thanks for bringing this to my attention. I must have just been lucky in that I always had a ceiling when doing this. I might have to update this guide to reflect that requirement.

With loft houses, is there any way to use ceiling lights in the double-story section without them having to 'hang' from mid-air on the lower level?

Unfortunately, if you want light in the lower section, yur best bet is to use wall or stand lights. I thought that light (from lights or sunshine through windows on the upper floor) would shine down to the lower section, but seems I either dreamed that lol, or it has been changed

When I was building the Dormer Windows, I would move the roof to the side, and it would go through the walls and be in the room, blocking it off and filling it with the continued roof. Is it supposed to be like this or am I doing something wrong?

I'm trying to visulise what you mean and think I understand. Does it do that in live mode too? Often roof pieces merge into rooms while iin build mode, but once you go to live mode, everything is fine.

Hi! Never posted here so first off, thank you SO much for all the info you provide! Smile That said, I recently purchased all TS4 games and am still in the process of remodeling my couples' "dream house," heh. In the basement I'd like to build a little stage for comedy/music. Nothing huge, but a small elevated level like TS3 allowed. I've been trying to do so with the tips here but nothing's working. Does anyone know if this is possible?

(Note: The home is already on a foundation, in case that matters. I assume the problem is it being in the basement?)

I built up a huge house and then decided I wanted to experiment with split levels. Keep in mind the house has already been built. After following your steps I hit a wall when it came to putting down flooring. No matter what I tried the game still would not read the lower level as a room. I didn't remove walls and there was a ceiling above. Does the room have to be a rectangle? Mine is a bit odd in shape. Or does this not work after you have already built the house and you are adding this as an after thought?

I figured out how to do it on he lowest floor with my foundations on 3 but I want to do this in a room on higher floor within the house.. any help or tips would be great. thanks x

It is just the same process as splitting the ground floor and first floor. Smile For example, if you had a 3 story house you could have a split level bathroom across the top floor and the 2nd floor by drawing a fence across the top floor and placing stairs up from the 2nd to the top.

Does anyone know if there is a way to change the sunken room "wallpaper" to something else instead of foundation? Would love a way to use something other than what options we have for foundation designs. Thanks :)

Not that I know of in the vanilla game. Maybe some CC creator has made different foundation patterns that would look more like what you have in mind. There are some really great CC wallpapers out there so have a look around and hopefully someone has made new foundation colors too.

Hi all, I'm having an issues when making a second story, open to below in one of my houses. From the upstairs everything is fine, and I can see into the downstairs living room. But when i'm downstairs looking up, I can't see the upstairs, only 'sky' as though I had no roof. The lighting and everything is okay, I just want to be able to see the two floors at once from the downstairs. Thanks in advance!

That is just how the game works. If you put all the walls up and then go into 'tab' mode and move around with the arrow keys then you will have a 'better' view but in ordinary live mode, that is just what it looks like.

I am having a problem with my house with a loft. For some reason it seems that removing the floor on the upper level is disabling the counters and the refrigerator and my sims can no longer cook as a result. I though I had solved the problem by replacing all the wall I had drawn freehand wit walls I made using the "L" shaped room tool. That worked for awhile. Next thing I know she was right in the middle of cooking, stopped, and started waving at me. She was all of a sudden no longer able to use the counter top she had just been using. Nothing changed...she just realized there was a loft again. Any suggestions on how I can fix this? Thank you.

Did you use MOO to place the counters etc as that can cause issues. I've not had a problem with removing ceilings before (to make a loft) so I'm thinking that something else is causing the issue.
Gravatar

Karensays...
Nooe, no MOO, at least not in the kitchen. I agree it was not the roof/floor. I replaced the floor and figured out it was not the counter she couldn't use but the stove. I tried debug the stove, no good. I deleted the hood, no good. I moved the stove away from the wall and it worked. Problem is I want it against the wall. I changed the place with the counter next to it and the stove works there (but not on the other side).

She eventually got frustrated and transformed the stove. It turned into a chair so we don't even have to worry about it anymore. She cannot afford another stove right now.

Well, least you found out what the problem was! I suppose your sim will get more use out of a chair!! Laugh

I'm trying to build the split level. I replaced the wall with the fence like you said and placed the stairs but the fence is blocking the stairs. Sorry I can't explain it well LOL. If I try to remove the fence in front of the stairs it is no longer recognized as a room.

I do know what you mean. I've been having the same issue in my game. This feature seems pretty buggy right now. Just keep trying to place the stairs through the fence and eventually it happens. Try it the other way around too, place the stairs and then draw the fence.

Not if you are trying on a water lot as there are no basements or terrain manipulation possible on any lot in Sulani that is on the water. Also on all land lots there is a basement bug at the moment which the devs do know about. Bug Report (Click)

SJsays...

Trying to recreate my parents house (no idea why). Thing is, the stairs are on two levels; the first is 12 stairs, then there's a bit of a mini-landing which goes from wall to wall, then another 3 stairs.

Even though we've now got split stairs, they're no use because the split has to be on the same level as the first part of the stairs. Even trying a split level doesn't work because I don't wan the fence going all the way across, and I only need the stairs to be a maximum of two tiles wide.

The main part of the stairs faces away from the front door then, when you get to the top, there's a bit of bannister across the landing from the other part (3 stairs), in other words, the split is kinda over the stairs, if that makes sense (basically part of the hall ceiling is over the stairs). Stairs, bit of landing, stairs to main landing - make sense…? There's also a 3 x (2 x 3) pane window on that wall.

So I need to build 3 stairs down from the split, then have the half-landing (or whatever you call it) then another 12 stairs down to the hall.

I also need carpeted stairs (very common in the UK), but I can't find any, so perhaps it's either a) because it's not possible to carpet stairs, or b) we're just weird and nowhere else on Earth has carpet on their stairs.

Kaitlynsays...

I'm a bit confused by that (or maybe I'm not), but either way I am not good enough at this to know how to fix that. For the carpet on the stairs, in the US we had carpet on our stairs in the 90s but for some reason people don't like carpet anymore and are ripping it out. That's the only reason I can guess as to why EA didn't include it. I'm willing to bet you can find carpeted stairs CC, like from oldbox, but I am not sure they will work for the new sims stairs. Instead of a runner that looks like carpet, you would have to find an entirely new meshed staircase that has been updated.

I put lofts in my Sims house on Friday. I don't know if my sim was able to go up to the loft above ground(I put a loft in the basement also) then. I started playing on Saturday and my sim couldn't go up to the loft. I had to put the floor back before my sim was able to go up to the loft. I followed this guide. Just wondering if anyone else is having this problem?
