Private Kiawah Island, SC Residence
Kiawah Island, SC, USA
1,500 sf. Greenroof
Greenroofs.com Featured Project December 1, 2020
After re-reading last week’s #TBT article Back to Nature ~ An Alternative Approach to Planting Green Roofs by Haven Kiers, MLA, GRP, we were inspired to once again highlight this lovely family home designed by Thomas & Denzinger Architects and Wertimer & Associates Landscape Architects, and installed by Living Roofs, Inc.
With plenty of natural features integrated to attract local wildlife, this private residence and its living roof blend effortlessly into the marshlands just beyond.
Excerpt from Greenroofs.com Project Profile:
This private residential green roof is located in the marsh sensitive ecology of Kiawah Island in coastal South Carolina. The semi-intensive green roof works not only to visually delineate the union between the building and the surrounding tidal marsh environment but also works to protect the vital buffer zone from harmful storm water.
The homeowners enjoy full access to the roof via slate pavers that lead to a wonderful outdoor space overlooking open marshland.
The green roof is a custom built-up system with subsurface irrigation, installed by Living Roofs, Inc. Waterproofing from Sika Sarnafil and Xeroflor GmbH (Bonar) drain mats were used throughout the green roof ensuring a watertight structure and providing both water retention and drainage.
The vegetation is made up of five species of grasses including natives such as Muhlenbergia and Nassella. Perennial grasses were chosen in order to create a seamless visual transition from the roof to the marsh below.
Two pieces of marsh cedar driftwood collected from the surrounding environment were placed among the grasses providing natural design and habitat for marsh species.
The green roof was installed in May of 2011 and by the end of the same summer, fiddler crabs were found crawling through the grasses on the roof!
The Private Kiawah Island installation was challenging as space was limited for staging materials and lifting the growing media and pavers to the roof, but the team at Living Roofs, Inc. persevered through hot and muggy Charleston weather to finish this very successful project.
