Building Frame of the House, Japan, by IGArchitects
Designed by Japanese studio IGArchitects as an adaptable space for both living and working, this house was envisioned as "one big room".
"[The clients] have a vague boundary between their private and work life, therefore they were imagining a house where they can work anywhere and where they can sense the presence of each other wherever in the house," IGArchitects founder Masato Igarashi told Dezeen.

Brutalist townhouse, UK, by PricegoreÂ
In Chelsea, London, architecture studio Pricegore renovated a four-storey modernist townhouse to create a three-bedroom home. The studio embraced the 1960 building's existing brutalist design focusing on concrete elements and exposing material finishes.
"The new works take their momentum from the existing building," Pricegore co-founder Dingle Price said. "There is no contrast, either internally or externally, between the old and the new."

Arizona house, USA, by The Ranch Mine
Phoenix-based architecture studio The Ranch Mine was informed by a nearby 1950s, mid-century modern house called White Gates for the design of this desert house in Arizona. The house has breeze-block walls and a roof cutout for a palm tree.
"Knowing the history of this home, the architects knew immediately that they had the challenging task of creating a new neighbour that should honour the legacy of the mid-century modern icon, while adding a distinctly new chapter to the story of this unique neighbourhood," said the studio.
