Teign Valley & East Dartmoor

Plan a route around 6 homes (opens Google Maps in a new tab)

Homes taking part

Each home is opened by the people who live there. Times vary, so check before you travel.

Barn End

A Grade II listed cottage built of stone and cob with parts dating back to medieval times and a 21stC timber frame extension. The retrofit has brought the building to a “heat-pump-ready” standard, with three underlying principles of 'fabric first', 'energy efficient heating' and 'ventilation control’, all within the constraints of listed building consent. The nearby modern Teign Valley Community Hall is also open as a contrasting companion visit, timed so you can visit both.

Tours and talks: Tour 1 2.30pm (around 30 min), tour 2 3.15pm (around 30 min) - tour of house and heat pump plant, informal Q&A

Cottage is not wheelchair accessible. Steps between different levels on ground floor. No dogs please (we have cats!) Private home so very small groups of up to 5 or 6 can be accommodated at a time.

Campion, Marsh Lane

Although not a passivhaus our house is, we think, pretty interesting and green. We have triple glazing, high levels of insulation, solar panels, an air source heat pump and battery. We also collect rainwater (when it rains!) in an underground tank to water the garden and flush the loos.

Downstairs is accessible, although Marsh Lane can be rough. Dogs welcome (we have a labrador). Teas and coffees and a chat.

Directions and parking: Please park half way along Indio Road and walk from there into Marsh Lane, (an un-named track). with large field on your left. Campion is first house on right (not on corner).

Dunsford Retrofit to a Modern House

Southwood House is just inside the Dartmoor National Park and was built in 2004 to standards of the day. We moved in during 2005 and have subsequently fitted:- secondary glassing to the existing double glassing on all front/south facing windows; extra cavity wall and loft insulation; a home EV charger; PV panels on the roof; a Tesla battery and a high temperature air source heat pump. The latter, while more expensive than a standard ASHP, meant the installation was simple, existing radiators were used and no under floor heating was necessary. It is critical to research options and have a detailed understanding of your heating needs before fitting a heat pump.

There is limited parking on the drive, or park 100m away just inside Britton Street

Directions and parking: If travelling towards Moretonhampstead on the B3212, our house is opposite the Z-bend sign, just before the Dunsford turn off. Park on the drive or Britton Street, the road going into the village centre.

Hillcrest Passive Solar Ecohome

Hillcrest is a beautiful architect designed 4 bed Ecohome that is now 18yrs old but still very contemporary. It displays all the sustainable design features you need to perform really well in our fast changing climate, incl bore water, ground source heat, solar gain & thermal mass, areas for growing your own fruit and Veg, wildlife meadow & flower garden. Being new owners we are in the throes of adding additional future-proofing features very relevant for now, incl plentiful rainwater tanks, Solar PV, a new orchard, wildlife ponds, EV charger, and more. The property commands gorgeous views nestled against broadleaved woodland on a hilltop, and is within easy cycle commute distance of Exeter!

Teign Valley Community Hall

A large 1990s community hall retrofitted with insulation, solar PV, battery, heat pumps, HVAC heat recovery ventilation system and smart controls. Includes aircon cooling in main sports hall. It's an example of how successful the three underlying principles of 'fabric first', 'energy efficient heating' and 'ventilation control' can be. There is one 14kW air to water heat pump serving radiators with smart valves plus a pair of two 14kW air to air heat pumps for the large HVAC system. There are also other energy saving features such as small, local hot water supplies on timers (probably the most effective energy saver of all for our hall). The nearby grade II listed cottage ‘Barn End’ is also open as a contrasting companion visit, timed so you can visit both.
