Sunken concrete floor expands Victorian terrace house in London

DGN Studio has extended and renovated a Victorian semi-detached terraced house in East London, introducing a sunken concrete floor to maximise the ground floor ceiling height.
Called Concrete Plinth House, the original brief – to transform a disconnected and dark north-facing kitchen into a bright and open space for gatherings – expanded to include lighter-touch renovations of the rest of the house.
