'Treatment Rooms' Mosaic House

The lowdown

On an otherwise ordinary Chiswick street stands an extraordinary sight, a whole house, walls and all, smothered in vibrant handmade mosaics and ceramic tiles. The work of the artist and activist Carrie Reichardt, who calls it the Treatment Rooms, it has taken decades to create and is crammed with colour, slogans and political messages on justice and human rights.

It is a private home, so you admire it from the pavement, but the riot of pattern and protest is free to see and utterly mesmerising. A genuinely unique piece of outsider art hiding in suburban west London, well worth the detour for anyone who loves the unexpected.
