An urban retreat with pollinators
Rooftop garden & bees
Designed in collaboration with award-winning landscape design practice Tom Stuart-Smith, the rooftop garden at 25 Cannon Street extends the workplace into a calm, elevated setting high above the City. Carefully structured planting defines a series of flexible spaces for informal meetings, events and quiet moments outdoors, with exceptional views of St Paul’s Cathedral.
Since 2026, the 5,400 sq ft garden has also been home to honeybee hives, supporting urban biodiversity and connecting tenants with nature in a meaningful, engaging way.
A tranquil oasis in the City
Reflection pool & public garden
At ground level, 25 Cannon Street opens onto a publicly accessible garden designed as a calm oasis within the City. Created in collaboration with Tom Stuart-Smith, the space has been thoughtfully reimagined to bring a sense of tranquility to its urban setting.
A central reflective pool, designed with water-feature specialist Andrew Ewing, mirrors the dome of St Paul’s Cathedral, establishing a striking focal point. The result is a carefully composed landscape that brings together design, nature and business.
Designed for wellbeing and connection
A modern workspace
25 Cannon Street is designed to support a modern, experience-led workplace, where wellbeing, community and engagement are embedded into the day-to-day environment. The building combines high-specification office space with amenities and programming that enhance occupier satisfaction and productivity.
The tenant experience is shaped by abundant natural light, high air quality and best-in-class end-of-trip facilities. A curated program of events – from rooftop gatherings to hands-on art workshops – further encourages connection between occupiers and their environment.
