when home owners erica and peter purchased a home on the shore of the thames in wraysbury, middlesex; they were told that their risk of flood was 1 in 100. as it turned out, their realtor was full of it, and after five floods in fifteen years, the worst ever being in 2014, the couple agreed that enough was enough. london-based firm BAT studio was contacted, who created a solution to provide safe refuge for crucial items in case of disaster, and a useful space for the rest of the time.

their design, titled the ‘greenhouse that grows legs’, does just that. four integrated hydraulic legs enable the building to be raised 800mm (approx. 2ft) above ground at the touch of a button. the use of hydraulics guarantees a level lifting, regardless of the location — and collective weight — of whatever the small auxiliary building has. timber is the primary material used, with accents of green paint and aluminum composite mirrors installed between each column.

  • Effective interlocking of the 4 axes would be a challenge – especially with all those mirrors.

    Adam Brocklehurst says:
  • This seems technological overkill. Why not design the building so it could float? Just weld barrels under the frame which it needed anyway to be liftable. That would prepare it for floods exceeding the limitation currently given by the size of the hydraulic jacks. Future-safe… (…and it would match what seems to be the owners’ floatable car.)
