I made a quick design.
and fixing element as one object (extrusions…)
Probably later for UV maps etc. I could break it 4 different types of elements.
0,25x0,25x0,25, 4x0,25x0,25, 3x0,25x0,25, 8x0,25x0,25.
Or may be left it as it is. Depends on texture complexity I desire.
May be one single object like this for one single room is a good idea.
