A new double height extension in a Grade II mansion in Holland Park, West London.

Whilst the street frontage features distinctive bow bays and grand openings, the rear is unconsidered by comparison as a result of later additions and patched in services.

The proposed two storey extension, evolving through an iterative process of consultation with English Heritage, 'borrows' the round bay vernacular to provide a large entertaining space at ground floor level and sunken library/garden room.
