ThreeStyle adds a humble but critical twist to the typical contemporary door – nothing too off-the-wall in terms of its aesthetic, but novel in its approach on a more fundamental level. Simple metal handles sit on wood-paneled frames which, in turn, stack neatly within one another like nesting dolls or something out of Alice’s Wonderland. While it is not their only offering, SlamDoors Ltd.’s line of modular doors is led by this innovative new approach to a design object as old as the idea of dwelling itself.
