Overlooking the Thames with unbelievable views from St Paul’s to Big Ben, we were asked to create a two storey penthouse on top of a historic theatre. The simple volume conceals a vast living space and roof terraces which frame the ever changing city skyline. By carefully cutting back the existing building at 7th floor, and gaining consent for an additional 8th floor, the resulting plan is able to connect each space with the city outside. Minimal, acoustic glazing is used to keep views uninterrupted, whilst everyday life continues within. A simple palette of materials is used to connect separate spaces whilst keeping each individual and specific. Marble in the hallway re-appears in the kitchen and in the master suite. Oak and Walnut are used for warmth in large areas, carefully controlled through intricate detailing.
