A new two-storey extension to an Arts & Crafts house creating a spacious family home

Westbourne House is just south of Cardiff on the coast of the Bristol channel.

The idea was to leave the Arts and Crafts house to the street, and then build an extension that looks like a completely new house from the back - with none of the original house visible.

The extension is thus as large as the original house. The volume and proportion of the new is very close to being a mirror of the original. The aesthetic and facade treatment is however very different. Whilst the original house was closed to the garden and with very cellular rooms, the new is fully open to the garden, and very open plan.

The back wall of the house is twisted, partly to reduce the impact of the upper floor on the neighbour, but also partly to accentuate the rake of the sliding doors as they slide behind each other. The doors are sized as progressively smaller, creating a subtle false perspective emphasising the twist.
