A New Chapter for
GROSVENOR SQUARE
This summer marks a significant moment in the evolution of Mayfair. On 20 July 2026, Grosvenor Square will reopen to the public following an ambitious transformation that has reimagined one of London’s most historic garden squares for a new generation.
The culmination of almost a decade of planning and consultation, the project represents the largest private investment in public green space in the West End in a generation. Only the fourth redesign in the square’s 300-year history, it reflects a broader vision for Mayfair as one of London’s most desirable places to live, work and spend time.
For residents of No.1 Grosvenor Square, the reopening brings an extraordinary urban garden quite literally to their doorstep. Designed to balance beauty, wellbeing and biodiversity, the renewed square introduces more than 70,000 plants, 44 new trees, wetlands and thousands of bulbs, creating a natural sanctuary in the heart of central London. Meandering pathways, enhanced seating areas and thoughtfully designed spaces invite residents and visitors alike to slow down and reconnect with nature.
Beyond its horticultural ambition, the redesign has been shaped by how people live today. Improved access, enhanced lighting, new amenities and a greater sense of openness ensure the square functions as both a place of retreat and a vibrant neighbourhood destination. A new education centre and café will further enrich the experience, creating opportunities for learning, connection and community engagement.

“Together, these additions reinforce Mayfair’s position as one of the world’s leading luxury destinations”
The reopening also arrives at a pivotal moment for Mayfair. Alongside the recent opening of Chancery Rosewood and the arrival of Bonheur by Matt Abé, Grosvenor Square sits at the centre of a neighbourhood enjoying a renewed cultural and hospitality renaissance. Together, these additions reinforce Mayfair’s position as one of the world’s leading luxury destinations, where exceptional dining, hospitality, green space and residential living coexist within a remarkably walkable environment.
Three centuries after it was first laid out, Grosvenor Square continues to evolve. Its latest chapter not only enhances the daily lives of those who live around it, but further strengthens the enduring appeal of one of London’s most prestigious addresses.
