The building, owned by Japanese financial services company the Nomura Group, is London's first carbon neutral building. The sixth floor terrace, with views over the City and the Thames, is the size of eight tennis courts and is open to staff and clients who fancy eating al fresco. The formal gardens feature hedges, shrubs, herbaceous plants, ferns, herbs and grasses.
The kitchen garden is made up of 12 vegetable beds, which are managed voluntarily by the building's switchboard team. The edible garden has about 25 varieties of vegetables and flowers, used daily by the company's chefs. The surplus is offered for sale to staff, with profits donated to charity.
The garden will be accessible to the public for Open Garden Squares Weekend 2014 (Saturday June 14 and Sunday June 15 10am-5pm).
