@Psychotps That's strange.
You weren't able to build any walls, like totally separate from the house when not making a room?
Which room type did they want? I got a nursery for an apartment and couldn't do anything to the place. The second client wanted an in-laws addition but I couldn't touch anything they already had. The third client wanted any type of room and I couldn't touch anything that was already there. For these I also couldn't exceed the tile count. The last job I had to do a gym addition. I could make the room bigger than the client wanted and I could get rid of and shuffle around their existing items. (Here's a short clip from the last gig. I'm sorry for the potato quality..)
