23 Queen Anne Street

At 23 Queen Anne Street, two new green terraces were created as part of a major refurbishment. Featuring a living wall, planters, beehives, and wildlife habitats, the spaces enhance biodiversity and provide staff with a place to relax and connect with nature in the heart of Marylebone.

As part of a full building refurbishment at 23 Queen Anne Street, approximately 30 square metres of new green space were introduced across two terraces. The design incorporated a range of features to support local wildlife, including a green wall, trellises, planters, seeding areas, beehives, bird boxes, and insect habitats. These additions are helping to boost biodiversity in Marylebone and weave the building into the area’s wider ecological network.

The terraces were finished in 2021 and have quickly become much-loved spaces for people working in the building. Especially during spring and summer, staff make good use of these peaceful spots, perfect for taking a breather, recharging, or simply enjoying a bit of nature in the heart of the city.

In addition to supporting wellbeing, the terraces have a practical environmental role. The terraces provide permeable surfaces to manage stormwater, and rainwater is harvested to use within the irrigation system, keeping the plants thriving. By combining wildlife-friendly design with sustainable water use, the terraces show how urban offices can make a real difference for both people and the planet.
