London studio Hayhurst and Co has reorganised Hampstead Town House around a triple-height void, transforming the interior of the north London home while retaining its distinctive 1970s exterior. Hayhurst and Co completely overhauled the skinny house, which was originally designed in 1970 by architects Igal Yawetz and Howard Radley.
