Temple Park Crescent, Edinburgh

PROJECT DESCRIPTION

Temple Park Crescent is a new build residential development designed with sustainability objectives in mind, located on the Union Canal in Merchiston, Edinburgh. S1 Developments delivered this challenging project as developer and main contractor alongside Ashton Building Systems as the specialist roofing contractor. The goal was to provide a sustainable block of high-quality homes, which integrate fully into the existing tenement form of the street. S1 Developments specialise in challenging city centre sites, and having worked with this client for many years, we were approached as the partner of choice to find the best roofing solution to suit their needs.

PROJECT REQUIREMENTS

This roofing project had to incorporate features designed to support the project's sustainability goals, and fit into the local landscape and be cost effective.

Another important factor that needed to be considered as part of the project was the City of Edinburgh’s ambitious goals to manage rainfall and drainage. The project requirements included the incorporation of a green roof to support the development's drainage and planning objectives.  This would not only support the planning regulations, but also help provide habitat opportunities for plant and animal species, subject to the final roof design, planting specification and ongoing maintenance. We worked closely with the architect and client to agree a design that could be installed efficiently – something that was especially important given the complex location of the build in between the canal and a tight residential area.

Working collaboratively with 7N Architects and S1 Developments, we proposed a mechanically fastened single ply system using Sikaplan SGmA-20 membrane for the green roof and Sikaplan G-18 membrane for the Mansard roof and terraces. Sika’s Extensive Green Roof System was installed over 222m2.

This system incorporates SikaRoof substrate, which is made up of 100% recycled materials. The SikaRoof vegetative sedum layer is free draining, low nutrient and moisture retentive, thus supporting the commitment for improved urban drainage,an essential requirement of the City of Edinburgh. The sedum layer incorporates up to 12 plant species, which also support and promote the growth of local wildlife and flora/fauna in the area.

The Mansard Roof and terraces used a traditional flat roof buildup using SikaShield as the AVCL (Air and Vapour Control Layer), Sikatherm PIR AL as the insulation layer and finishing with Sikaplan® G-18 membrane using a mechanically fastened system.

The result is a green roof system for a modern luxury residential development in Edinburgh’s city centre. S1 Developments are delighted with yet another successful collaboration, having successfully delivered a roofing system that met the project's design, performance and budget requirements. The project has been awarded our Sika Performance Plus guarantee of 20 years.
