A GARDEN IN THE SKY GRAPHISOFT 33 Central is a striking building located at the gateway to the City of London. Topped with one of the City’s largest roof gardens, and achieving a BREAAM Excellent rating, the building not only offers a flexible modern office space but is also a fine example of sustainable design and construction. John Robertson Architects (JRA) managed the project over a ten- year period, through feasibility studies and planning consent, to detailed design and overseeing construction. The original building at 33 King William Street was constructed in the 1980s. In 2008 the then owner, property and investment group Topland, asked JRA to undertake a feasibility study to refurbish the existing building. However, following this study, the decision was taken to demolish and re-build.
