Untitled House, UK, by Szczepaniak Astridge

Smooth, dark, concrete characterises the walls and monolithic bathtub of this bathroom, which Szczepaniak Astridge designed as part of a house renovation in Camberwell, London.

The bath is screened by stainless steel Crittal windows that enclose a void through the home and is teamed with a bespoke, polished stone sink. According to the studio, the aim was to design a “place to retreat to, to guiltlessly linger and hang out”.

Cloister House, Australia, by MORQ

The shell of this Australian house is made from rammed-concrete, which has been left exposed in the bathroom and other interior spaces to create “a sense of refuge”.

Its textured, brutalist aesthetic is softly lit by a small window at one end, and warmed by a brushed nickel tapware and a rough-sawn red hardwood ceiling, vanity and joinery.
