Few design techniques can transform a room as the enhancement of its walls. Wall treatments have never been so exiting and unconventional from highly crafty fluted plaster walls to artistic pyramid paneling walls, architectural motifs that were accredited for exterior texture and furniture have been forever moved inside to residential interiors in never-seen-before ways. Most of the time the effect is so impressive and powerful that little else is needed to complement the already aesthetic walls. The more traditional methods such as the ones used in the first four rooms, fluted walls, are not an alternative for DIYers. It is a skill to leave only to professional hands. The more modern texture walls such as wood block stacking, tiling and origami would be an easier choice for very clever, handy home owner.
