Green innovation was at the forefront of designs for a
stunning, award-winning family home created at Manaton, in
the heart of secluded Dartmoor. |
 |
|
Rhepanol hg was selected for the three distinctive green
roofs that help to shape the character of the large, four
bedroom Devon property, which incorporates a raft of
measures to minimise its environmental impact. |
|
Architect Peter Hall of Van der
Steen Hall in Chagford was asked to create the house as a
permanent home on the site of the owner’s well-used holiday
bungalow. Materials from the bungalow were recycled and used
in the new house. |
|
He said: “We chose Rhepanol
membrane and accessories for the complex and varied profiles
of the roof planes – very different from the large,
predominantly flat areas of typical grass-roofed office
blocks -because of the help and advice we received from the
approved subcontractor and from the D&T representative.” |
|
The roof, which covers a total
of 250sq m, was key to creating a home in harmony with its
rural setting. It complements the unique ground-hugging
lines of the house and outbuildings, which are set down into
the sloping countryside, nestling in surrounding woods and
farmland to create a “magical” setting. |
|
The roof make-up comprised
natural, local meadow grass and site-excavated topsoil on
cuspated drainage layer /root barrier on Rhepanol hg with
stainless steel gravel stop profile- adhered to membrane at
perimeter and at intervals up steep slopes. The Rhepanol hg
membrane was laid over softwood boarded roof, dressed into
softwood eaves gutters and onto top of the fascia. Rhepanol
also forms fascia, cill and jambs of the window in the roof
– see second photo.) |
|
As the grass roofs, thick
granite walls and oak joinery slowly weather, they will
blend into the surrounding landscape. There are also plans,
for the future, to provide heating and hot water by
extracting heat from the surrounding ground. |
|
Said Peter Hall: “The natural
materials, high insulation levels, thermal inertia and
ground-hugging profile all contribute toward a very low
environmental impact.” |
|
The Manaton house was awarded
Devon’s 2008 RIBA Arnold Sayers Housing Design award. |
