Location: London, United Kingdom.

Architect: Pilbrow & Partners.

Four pavilions will be built in Grosvenor Square in London to enhance its character while preserving its cultural and historical significance. The pavilions will be located in the spaces of the former ring roads around the central gardens and will provide clear and welcoming points of entry. They will also provide a varied programme of events, activities, and public facilities to encourage locals and visitors to come, stay, and return. The pavilions are designed to grow from the landscaped perimeter boundary of the central gardens and will be visible on the lines of approach to the Square, marking clear gateways to welcome visitors. The first pavilion, the Café, will be located in the north-east corner and will offer a range of organic produce partially sourced from the glasshouse on the opposite side of the square. The second pavilion, the Hub, will be located in the south-east corner and will provide a flexible space for events, exhibitions, and seminars on the theme of urban ecology and sustainability. The third pavilion, the Glasshouse, will be located in the south-west corner and will provide a base for horticulture across the Square. The fourth pavilion, the Auditorium, will be located in the north-west corner and will host a variety of events and performances offering a rich cultural programme to animate the Square. The pavilions will balance the benefits of activation with preservation of the existing Square’s significant cultural, historical, and heritage importance. They will also complete the enclosure of the space, controlling access out of hours. The landscaping of the central gardens will preserve its generous lawns but look to enrich the perimeter planting to enhance biodiversity. The Glass House will be an educational resource, hosting school visits with programmed activities extending out into the Square itself. Plants will be available for sale and seasonal produce grown within the Glass House will also supply the café on the opposite side of the Square. The pavilions will transform the character of Grosvenor Square while preserving its essential qualities.
