Cosy House
by Enbee Architecture and Design

Public vote winner: Sustainable interior of the year 2026. Enbee Architecture and Design has designed the interiors of Cosy House in London, United Kingdom.

Through deep retrofit and careful material reuse, an end-of-terrace Victorian house has been transformed into a light-filled, atmospheric, low-carbon home.

This project creates many curious and surprising moments through its spatial design, while insulation and fabric upgrades are calculated to reduce energy use by approximately 85 per cent.

A salvaged spiral stair and natural material palette bring texture, warmth and surprise, resulting in an enchanting, high-performance home fit for the future.
