Project Description & Details
The National Trust is Northern Ireland’s largest conservation charity and the Portstewart Strand, nestled amongst a two mile stretch of award winning beach and sand dunes, has been designated an Area of Special Scientific Interest and a proposed Special Area of Conservation. Meeting the highest environmental standards, the new National Trust Visitor Centre at Portstewart Strand is designed to maximize energy from natural light and the structure was constructed with cedar panels from renewable sources and includes a greenroof; the vegetation and the timber will weather naturally to blend in with the landscape.
Donnelly O’Neill Architects of Belfast were challenged with a design brief that was strict in its requirement. The roof needed to be sympathetic to its surroundings and in keeping with the environmental ethos upheld by the National Trust, while the exposed location of the centre also presented the problem of wind erosion. Alumasc was able to provide a complete waterproofing and ZinCo greenroof package that not only met the technical specifications, but which has also provided a valuable resource for local wildlife that will continue to flourish over time. It is expected that the grasses that cover the sand dunes will propagate the sedum roof over time, blurring land and roofscape even more.

Sustainability is also key and in accordance with the Trust’s policy of managed coastline retreat, the facility, which is built on sand, is demountable, so it can be relocated with minimal impact. As a result, its usable life will be longer than normal.

Isn’t it cool how no matter the season and the light in these photos that the greenroofs’ colors blend into the site almost seamlessly?
