I really like the concept behind PopUp Houses as well as the houses.
A simple concept: Build an entire building (floor, walls, ceiling) by assembling insulation blocks separated by wooden boards.
Rapid Installation. Use of lightweight materials. No special tools required, assembles like Lego.
Low Cost. Inexpensive materials. Very short assembly time.
Recyclable. Use of recyclable materials. Quick disassembly.
Outstanding Insulation. No thermal bridge at wall ceiling junctions. Almost no additional heating required.
