Spacehub worked with on behalf of Tenacity with architects KPF on the landscape and public realm proposals for 70 Gracechurch Street.

The proposals are united by a single concept – the hard, mineral, city below which knits into its surroundings, and the green sanctuary of the wilderness at the upper floors.

On the ground floor a new passageway connects Fenchurch Street with Leadenhall Market to the north. Lime Street is enhanced by extending the existing surface of granite setts down to Fenchurch Street. Connections to the wider city are improved with widened footways and the planting of street trees. The yorkstone paving extends into two ‘Forum Halls’, providing a canvas for public events to take place.

The upper floors are enhanced with an ambitious urban greening strategy. The terraces at 4th, 5th, and 6th floors provide outdoor amenity space for building users. Vertical greening in the form of trailing plants and trees planted between the three tower elements enhance the architectural form, mitigate air pollution and foster biodiversity in the city.

At the roof level, an amenity terrace inspired by the artist and sculptor Hans Arp will create a sanctuary from the city below, with a wild character befitting of its high location.
