A London Square development has utilised a green roofing solution from Sika Sarnafil, Sky Garden and Contour Roofing to create a luxury rooftop garden area for residents.
During its development, the modern apartment building required a roofing solution that would offer high performance and provide a biodiverse and sustainable communal garden for residents.
The project was split into three parts; the accessible green roof for residents on the first floor, then the green roof and brown roof at a higher level to assist with the disposal of rainwater.
Jonathan Woods of Contour Roofing suggested using Sika products, as the roofing project was complex and expansive. Although it was a challenge to change the specification at such a late stage in the development, Contour and Sika provided a solution that exceeded the client’s expectations.
A full warm ballasted system with Sarnafil G410-18RL Light Grey was specified as the main roof sheet for the main roof, balconies and podium, with Sarnafil G410-15EL Light Grey and S327-15EL Light Grey for the flashings.
Sika and Contour worked with Sky Garden in creating the biodiverse communal gardens, which featured amenities, communal seating, lawns, timber pergolas and established planting. Sikalastic Liquid Applied Membrane was used on the detail areas and balconies, achieving a 20 year guarantee.
Sky Garden provided technical support and information for the hard and soft podium landscaping, biodiverse habitat creation and green roof requirements to ensure that the systems met all BREEAM ‘Very Good’ certification requirements.
The three companies worked together closely with London Square to ensure that the challenges of a strict budget, tight programme and mid-London site with restricted access were all met successfully.
James Ansell, Development Manager at London Square, said: “We were really impressed with the finish on the Bermondsey Village building. The work that Contour did was of the highest quality and were very happy with how everyone worked together to deliver a high performance solution.
The Sika Sarnafil solution looked visually stunning and we were particularly assured by the level of guarantees offered by Sika across the whole roof, as this gives us piece of mind for the future. We are now working with Contour on a number of projects going forward.”
