Unconventional terrace extension:Trace House merges British and Japanese ideas and is up for RIBA House of the Year 2016

When this terrace house became structurally unsound, instead of pulling it down, it was kept together in a surprising and delightful way... 

House of Trace is not a new build, but a “surprising and delightful” rethink of an existing terrace house extension which had become structurally unsound.

The design makes a feature of the old and new elements of the house, including a central void which marks the delineation between the two parts, creating unusual interlocking shapes and functions of the rooms.

It is one of five London properties that are longlisted for the Royal Institute of British Architects House of the Year awards.

Trace was designed by Tsuruta Architects, which merges British and Japanese design and culture.


In the new master bedroom, an external window looks on to the garden while an internal window looks through the central void into a child’s bedroom.

Judges called it “a very clever project which brings an entirely fresh approach to the terraced house/extension typology” which lovingly preserves “age, patina and even structural faults”.

The Riba House of the Year award will be broadcast as part of a special Channel 4 Grand Designs series, presented by Kevin McCloud later in the year.
