Case Study 2 – Green Roofs

10 Queen Street Place is located directly east of Southwark Bridge and closely neighbouring Cannon Street Station. The strategic views of St Paul’s Cathedral cut diagonally through the development. This led to a large area of lower roof on Level 4. During the retrofit of the building, the opportunity was taken to make the space on the bank of the Thames into an amenity for the clients and tenants.
Total Roof Area (m²): • 4905 Total Green Roof Area (m²): • Soft Landscaping ‐ 302 • Hard landscaping – 2170 • 50% coverage of the roof Build Cost (m²): • £237 – excluding waterproofing and insulation Type of Green Roof: • Intensive roof • Hard surfaces in timber and paving on the Level 4 terrace. • Soft landscaping featuring grass & planters o Substrate Depths: Grass – 190mm, Planters – 490mm
The green roof at 10 Queen Street Place was designed purposely to provide an amenity for the people who work there. Research has shown having access to open green space can reduce stress and have a positive impact on human health. Green roofs may therefore be able to assist in a healthier and more productive workforce because of their interaction with the green roof.
