Real home: a contemporary wooden annexe to replace a garage

Jeremy and Jane Walwin replaced their old garage with a cube-shaped annexe for the extra space they needed

As Jeremy and Jane Walwin’s children had left their 16th century home in Somerset, they needed an annexe to accommodate their children and their partners on special occasions. They also wanted more space for their hobbies, such as Jane’s love of silversmithing, and a safe place to store Jeremy’s sports cars.

They couple originally planned on adding an ordinary room above their existing garage, but when they saw their architect’s plans, they soon fell in love with this unusual annexe design. The boxy, cedar-clad structure was designed by architect Nigel Humphrey, and is affectionately called The Cube.

The annexe is such an improvement in size, shape and practicality compared to their old leaky garage. The Red cedar cladding is from Benchmark timber, the glass porch is from Optigen Engineering

The three-storey build features a mezzanine level which has been split into two sleeping areas, reached by ladders. It also houses a living area with kitchenette, separate shower room, a hobby room and extra storage space.


The coffee table is from Acorn Upcycling, for a similar modular sofa, try Ligne Roset.and for a similar wooden wall clock, try Zazzle

Plywood plays a big part in the interior. The wall and floor is supplied by Latham Timber and the ladders are from Mike Barber Carpentry. The wood burning stove gives a cosy feel, and is from Sandpits Heating Centre. The triple-glazed wooden windows are from Green Building Store
