18 of the Most Unique, Strange, Unusual Houses Ever Built

10.M-Velope Transformer House, Various Locations

Designer Michael Jantzen created the M-Velope Transformer House to demonstrate how a house could rearrange itself to suit the needs of the occupant. The slated wooden panels slide on a steel frame to move the walls, doors and roof into new positions. Inside the house, benches can be folded away to allow more room when needed.

At just 230 square feet, the M-Velope fits into a small space and includes elements of renewable energy, energy efficiency and sustainable materials in its construction. There are only 10 M-Velope Houses in existence and they are ideal for using as holiday homes or relaxation residences.
