This volume is a squashed pyramid, it has 17 T nut placements on it. 
If you buy two you can put them back to back to make a diamond shaped volume. If you leave a little gap between them, you can have a horizontal break.

Our volumes are made from 18mm plywood and have a textured coating on them.
They come in white, so you can paint them to match your walls colour scheme, or leave them as they are.

 the triangle is 75cm long by 80cm wide, it sticks out of the wall by 30cm
