These begin with passive measures
and a building form that orientates
the long axis of the house in an eastwest direction, thereby enabling
both beneficial heat gain in winter
and the exclusion of solar radiation in
summer, through the judicious use of a
cantilevered roof overhang above the
ground floor, south-facing glass facade.
A dramatic double-height space at the
heart of the plan, coupled with opening
vents in the long upper level dormer
window, provides opportunity for passive
stack natural cooling in summer months.
Furthermore, PV panels contribute to
energy generation and the whole house
is heated through a ground source heat
pump, which provides underfloor heating
and hot water.
Other environmental features include airtight thermally heavyweight construction
and triple- glazed windows (in excess
of current building regulation u-values)
and an earth tube ventilation system that
ensures running costs are minimised and
internal conditions are as comfortable as
can be.

Rainwater is harvested for toilet flushing,
clothes washing and garden watering
and appliances have been selected for
the highest rated energy-efficiency
available. A wild meadow garden and
living roof to the single storey garden
room enhance the strong ecological
value of the site.
House 19 is a fusion of architectural
moves, contemporary vernacular and
pragmatic sustainability features and
represents a benchmark for new houses
in historic locations.
