The Ark, Bioshelter in Little Pond, Canada
The Ark is a bioshelter in Little Pond that combines solar greenhouse technology with residential spaces, housing fish ponds, vegetable gardens, and thermal regulation systems. The design uses three-layer inflated domes to capture sunlight while retaining heat for year-round food production.
This structure was built in 1976 as a pioneering residential bioshelter designed through research by the New Alchemy Institute. The project remained active until 1991 as an early demonstration of passive solar heating combined with food production.
The facility blends traditional farming approaches with ecological engineering to create a working example of sustainable food production within a single structure.
The site is most accessible during warmer months, though interior spaces maintain stable temperatures year-round. Visitors should know that this is an active research facility, so access may be restricted.
The Pillow Dome technology uses three inflated layers that allow maximum sunlight penetration while providing effective insulation. This innovative material lets the structure handle extreme temperature swings without depending on conventional heating systems.
