Sloane Street Transformation, Royal Borough of Kensington and Chelsea for Cadogan with Royal Borough of Kensington, John McAslan & Partners and Andy Sturgeon Design

This landmark transformation of London’s iconic 18th-century Sloane Street into a ‘green boulevard’ is focused on heritage, sustainability, elegance, and community impact. Spanning 1km, with pavements expanded by 23% to enhance pedestrian safety, comfort, and accessibility, encouraging dwell time and supporting footfall for local events and cafés. 

Describe the context of this project, its neighbourhood and people.

In early 2025, Sloane Street marked the formal completion of a grand transformation, reinforcing its position as one of the world’s leading luxury destinations. The most significant streetscape improvements in almost 250 years delivered a 17% rise in Urban Greening Factor and 175% biodiversity net gain improvement. The project–funded by Cadogan, delivered in partnership with Kensington and Chelsea Council, architects and lead designer John McAslan+Partners– created a stunning green 1km boulevard from Knightsbridge to Sloane Square. 
 
Following over a decade of planning and extensive public consultation, the £46million investment includes significant widening of the pavements, along with a magnificent planting scheme from Chelsea Flower Show winner Andy Sturgeon, elegant street furniture and improved lighting to create a more welcoming environment for pedestrians, enhancing safety, comfort, and accessibility, encouraging dwell time and supporting footfall for local events and cafés. The scheme created 100 construction jobs, resulted in a £7million increase in economic activity, and facilitated approx.100+ retail jobs. 
 
The project marks a new era for Sloane Street, enhancing its elegance and timeless appeal as the epitome of a luxury destination that is equally ‘global-yet-local’ – enticing new visitors, while enriching the experience for the local community. Defined by tradition and innovation, the transformation amplifies a sense of craftmanship, creativity and heritage, seamlessly connecting the experience created by the world’s most iconic fashion houses out into the public realm. Every aspect was meticulously considered, including the exact hue of Yorkstone that ensures the Street feels warm and welcomes residents and visitors alike.

After more than a decade of planning and public consultation, Cadogan prioritised community interests to enhance Sloane Street’s aesthetics, accessibility, and shopping experience. Recognising that a successful destination retail strategy must resonate locally, Cadogan placed Chelsea’s people at the heart of the project.
 
Close collaboration between Cadogan, design partners, and local authorities, supported by rigorous traffic modelling and sustainability assessments, ensured accessibility, heritage protection, and future-proofed infrastructure. Engagement with residents, retailers, and other stakeholders created a balanced approach to functionality, design, and luxury retail, reinforcing Sloane Street’s position as a global fashion and hospitality destination, complemented by new openings from Dior, Valentino, and Bottega Veneta and partnerships with leading hospitality operators.
 
A refined palette unites the streetscape with honey-hued Yorkstone pavements, widened by 23%, paired with silver-grey granite and bespoke brass detailing. Handcrafted granite planters provide seating and subtle security, while artisan-designed cast-iron lighting columns inspired by the local Holy Trinity Church celebrate craftsmanship.
 
Sustainability was central, with UK-sourced stone, drought-resistant planting, and energy-efficient LED lighting reducing carbon emissions and enhancing safety. Over 100 new trees and diverse perennial plantings significantly increase biodiversity and soften the urban environment.
 
Complemented by Pavilion Road with its artisanal offerings, Sloane Street remains a cornerstone of London’s luxury and cultural ecosystem - internationally appealing, yet deeply rooted in its local neighbourhood. Cadogan’s goal is to continue amplifying the neighbourhood’s heritage, celebrating creativity and offering a destination where its people can experience both luxury and culture in a seamless way.

How does this public space bring people together, encourage inclusivity, and make a positive environmental impact to the wider place? 

Cadogan’s transformation of Sloane Street honours its heritage as a global destination for luxury while celebrating craftsmanship, creativity, and innovation to create an environment that unites the local community.
 
 Sustainability was at the heart of the scheme, with UK-sourced stone used for most hardscape materials and award-winning landscape designer Andy Sturgeon creating layered planting of climate-resilient flowers, shrubs, and over 100 new trees. State-of-the-art LED lighting reduces energy consumption while enhancing safety for residents and pedestrians. These measures have delivered tangible results: biodiversity has risen by 175%, the Urban Greening Factor by 17%, and pollution removal by 33%, mitigating heat island effects, improving air quality, and softening the urban landscape.
 
 The project involved intensive community consultations, and it continues to foster community engagement through cultural partnerships and public events. As Frieze’s inaugural Destination Partner, it hosted Modern Nature, an outdoor sculpture trail curated by Frieze to coincide with Frieze London and Frieze Masters 2025. Collaborations with the Saatchi Gallery extended bespoke artworks by British artists Sophie Mess and Faye Bridgewater into shopfronts, street furniture, and banners inspired by the planting scheme. Chelsea in Bloom also saw Sloane Street transform into a free-to-attend flower festival, with over 130 of Chelsea’s boutiques, hotels and restaurants decorated with displays inspired by the neighbourhood’s cultural legacy. Later this year, Sloane Street will host its first-ever Christmas Party, illuminating the neighbourhood with 34 kilometres of golden lights and 312,000 LEDs, alongside festive performances and pop-ups.
