I've been thinking of this idea for a while

An apartment which looks like a Rubik's Cube.

I'd try to be accurate to the colour placement of the cube, with the blue on the top as solar panels, the green on the bottom as the grass shining from the light inside, and the other colours as the lighting of multiple rooms and shining through the windows

The lines may be faint, but I'm going for an isometric style with windows with rounded edges.

My main problem is that I don't know if the edges of the building should be sharp, like a building, or rounded, like a Rubik's Cube. I have seen some buildings in real life with rounded edges on the top, so I might do that as well.
