London’s designer showhouse returns to Chelsea Harbour, where leading interior designers each build a full-sized room inside the Design Centre’s Design Avenue.
WOW!house, the designer showhouse London’s interiors world builds new each summer, returns to Design Avenue at Design Centre Chelsea Harbour from Wednesday 9 June to Thursday 8 July 2027.
The Design Centre first opened WOW!house in 2022, raising a complete house inside Design Avenue. Leading interior designers each pair with an international brand to make one full-sized room, so work usually made for private clients can be walked through.
Each edition has added to the house. A classical facade and a double-height Entrance Hall went up in 2025. The house now runs to 600 square metres, with 22 rooms and outdoor spaces by more than 21 designers.
The house has raised money through a charity partnership from the start. The 2026 edition supported United in Design through ticket sales and an opening-night WOW!gala.
Beyond its walls sit the Design Centre’s more than 140 showrooms, so a fabric or light seen in one room can be traced to its maker in the same building. Through the month, more than 20 WOW!talks put the designers in front of visitors.
The 2027 house is the sixth, and its designers and charity partner have yet to be announced.
