A 5 bedroom timber frame eco home built into the cliffs of the north coast of Cornwall
Heavy plant demolished an existing split level bungalow, crushing block and rubble
use onsite. Excavations into the sloping site created the ability to build ‘Tanzarra’
as a 2 storey house.
Strip foundations, preprufe membrane, 14 tonne of steelwork and approx 90 cubic metres
300mm poured concrete base, with starter bars were constructed first. That allowed
work on a single sided shuttered 2 pour (approx 100 cubic meters) retaining wall.
From these heavy groundworks, the timber frame was constructed - a 140mm timber frame
structure house with external block skin. Some steels are used to create large internal
spans. Beam and block and glulams are also used to advantage to create useable internal
spaces in a tricky sloping site. Posis joists were used for ease of first fixing.
The structure is topped by a warm roof construction, flat, offering excellent insulation.
200mm celotex and a 200mm soil 'green' roof, using local grasses and fauna propagated
onsite. Solar Thermal panels heat the passive house along with solar gain through
triple plazed windows. A heat recover and ventilation system offer filtered air all
‘Tanzarra’ was constructed to strict airtightness and has achieved an 85B score on
its energy performance. It is a prime example of LionPark’s high quality workmanship.
