The house is designed in different heights, according to the importance of the internal use and breaking up the main volume into a more domestic scale.

Deep cantilevered first floor terraces provide external covered amenity space for the bedrooms, protecting the ground floor from excessive solar gains while utilising the surrounding beautiful views.

Natural timber cladding and floors are used throughout with floor to ceiling glazing, a green roof has also been added.

Harrow House will have the longest outdoors private swimming pool in London at 50 metres.
