Stepping Stones Lead to This Daylit Dwelling in the Middle of a Pond

Two steel structures expand a family's existing living area while embracing the calming effects of surrounding nature.

London–based architects Hamish & Lyons replaced a set of unconnected and flood-prone outbuildings with airy and minimal steel-framed living spaces to create the Stepping Stone House. It took three years of repeated requests to receive planning approval, due to the existing home's listed status and location within a conservation area, green belt, and flood zone—but the finished product was well worth the wait.

Hamish & Lyons combined a new landscape design with playful details like a diving platform located along the deck. As the name alludes, stepping stones cross the pond abutting the main residence.

Stilts elevate the new spaces, keeping them clear of flood waters while also making it possible to swim underneath the buildings.

Minimalist steel stilts give the impression that the buildings are levitating above the water. Hamish & Lyons reduced construction time and site waste by prefabricating much of the additions off-site.
