CASE STUDY: Cornwall Terrace, London

A high quality development relying on Fatra FF807 to waterproof complex detailing

This John Nash designed  terrace from the 19th century overlooks London’s Regents Park. It  has been updated to the highest standards and has been described by the Daily Telegraph as ‘The world’s most expensive row of terraced houses’.

When it came to roofing the main contractor, Laing O’Rourke, continued to use high quality materials by selecting Fatra’s FF807 membrane to replace the failed asphalt roofing.

The original deck was removed and replaced with a Fatra warm roof system to give high insulation values and better drainage. The roof areas are divided into the individual terrace houses and involved complex detailing around the masonry party walls. Waterproofing around the new plant being installed on the roof also provided a challenge which required Fatra to make regular site visits to advise on detailing as well as inspecting the roof installation.

The membrane lasts over 30 years and comes with range of components to complete the intricate detailing required on a refurbishment project like this. Fatra FF807 can also be installed over existing asphalt or felt roofs, Fatra provide a roof survey service to help the designer ascertain which is the better option for their project.

Although in this case Fatra has been used on a luxury development, its’ cost effectiveness makes it also suitable for more modest projects that are not being supervised by English Heritage.
