Dezeen (December 2022) – Continuing our 2022 review, we have collected 10 residential extensions featured on Dezeen this year, from a weathering steel structure perched on top of a bungalow to a pair of concrete volumes added to a remote farmhouse.

The Perch, USA, by Nicole Blair
This weathering steel-clad asymmetrical house extension is perched two centimetres above a family bungalow in Austin, hence its name. Architect Nicole Blair was tasked with expanding the occupants’ living space without sacrificing any of the home’s existing back garden.
The unusually shaped extension rests on four steel columns and was assembled off-site to avoid disrupting the lot’s vegetation. Inside, living spaces are dressed in pinky hues and framed by tongue-and-groove wooden planks on the ceilings and walls.

Cascada House, Mexico, by Ana Nuño de Buen and Luis Young
A rectilinear metallic frame in a dark shade of green forms Cascada House, an airy apartment nestled within a lush surrounding that tops an existing 1950s concrete building in Mexico City.
Architects Ana Nuño de Buen and Luis Young designed the structure with two roof slopes that drain towards a central gutter which manages rainfall, while inside, the steel structure is left exposed to create a distinctive interior.

Casa San Cristobal, Mexico, by Marc Perrotta
Local architect Marc Perrotta replaced a “clumsy” volume with a concrete, glass and brick extension at Casa San Cristobal, a house in Mexico’s Mérida.
Containing most of the living spaces, this two-storey, U-shaped addition creates a trio of courtyards filled with lush native plants that are designed to provide relief from the tropical heat.
