With stunning views across the Heath to Hampstead village, the clients asked Charles Barclay Architects to update their penthouse flats to make the most of their outlook. The lower floor was re-organised in to the bedrooms and bathrooms, with the upper floor made open-plan for living, cooking and eating. Oversized sliding doors give almost frameless views and a large new rooflight brings light into the heart of the flat while a decked balcony features a built-in barbecue. The visual centrepiece of the flat is a sculptural cantilevered stair featuring a bench seat in hand cast glass. The generous dimensions of the spaces are underlined by the wide Douglas fir floor planks from Danish supplier Dinesen.
