Right Sized

At 750 square feet, the two-bedroom Shelter Dynamics Flex House is just the right size for an individual, couple or small family.  Laid out for maximum space efficiency, the vaulted ceilings and large windows make it feel like a much larger space.  For Millennials who don’t want the responsibility or cost of a large house or Baby Boomers looking to downsize, the Flex House is the ideal solution. And a 450 square foot one-bedroom and a 1000 square foot 3-bedroom version are on the drawing board.

It is one efficient little house.


he Flex House is produced with healthy materials for the safety and comfort of its owners, while at the same time, its focus on energy efficiency makes it healthy for the planet.  The house is crafted with FSC certified lumber, low or no VOC materials and exceptionally low GWP (Global Warming Potential) BaySeal closed-cell insulation.

Compelling and Fun

While many manufactured housing systems are designed around “stacked cubes”, the Flex House is full of curves, soft-edges and flowing lines.  The vaulted ceilings and large windows give it a spacious open feel, that makes it feel like a much larger space.  Yet, it is still cozy and inviting. Everyone who walks into the Flex House is enchanted.
