The Chelsea Mews House Extension project involved the complete internal remodelling, full home renovation, and rear and side extension of a traditional mews property. The design combines dark zinc and modern glazing to sensitively extend the property while respecting its historic mews context. The original layout on the ground floor lacked sufficient daylight and a strong visual connection to the rear garden. Small rear windows restricted natural daylight from reaching the ground floor, while compartmentalised internal rooms unnecessarily divided the kitchen, dining room and circulation spaces. The interior of the ground floor was completely transformed to create an open plan dining and kitchen area. The small rear windows were demolished and glass sliding doors were instated to introduce daylight into the space, while providing improved views of the garden. The side extension made use of a redundant gap to the side of the house, while allowing the footprint of the ground floor to grow. The choice of dark zinc matches the slate roofs and dormer windows along the street, while the tall glass panels mirror the proportions of the original windows. To the side, a modest quarter-circular extension draws inspiration from the curved brick walls typical of the local mews houses. Both additions sit low on a smooth concrete base, ensuring they stay proportionate to the main house while clearly separating the historic brickwork from the modern additions.
