Green roof system specified for Baker Street refurbishment

Central to the new developments was the refurbishment of the building’s flat roof, which included the creation of a green roof terrace area with impressive views across the West End.

82 Baker Street

The building consists of a number of roof areas, varying in different pitches and floors, totalling over 1,400m2.

The roof was shrouded with unsightly equipment and redundant air condition units which no longer served a purpose, and detracted from the appearance of the building.

Prior to undertaking the necessary remedial work, robust wind uplift calculations and weight loadings were performed Bauder to ensure that the new roof could resist the weather conditions it is likely to experience and bear the additional weight of the green roof system.

The original waterproofing on the main roof areas was removed before being replaced with Bauder’s premium reinforced bitumen system. This included a highly efficient tapered insulation for superior thermal performance and improved drainage falls, which ensures the roof achieved the required average 0.16 U-value.

On the ballasted terrace roof area, located on the building’s 5th floor, 400m2 of Bauder’s bituminous green roof system was installed with wildflower blanket around the roof perimeter.

Yefgeniy Beylkin, project specifier from Marks Barfield Architects stated:

“The Bauder Total Green Roof System with wildflower blanket installed at 82 Baker Street offers an oasis of biodiversity in the middle of the city. The green roof is made up of 24 native species of wildflowers carefully chosen by an ecologist not only for their attractiveness to wildlife but also for their low maintenance properties.”

“The new roof space offers the staff a sanctuary with a sense of nature combined with spectacular views over London’s roof tops, promoting well-being, as well as providing additional social and entertaining space for the company.”
