Chew Valley Passivhaus

PROJECT

Passivhaus in the Chew Valley

We provided site management, carpentry, drylining, cladding and cabinetry for the excellent Earthwise Construction in the build of this new passivhaus in the Chew valley.

The insulated timber frame was built off site and erected in a matter of days by an external contractor.

The heating for the entire house (all 240 sq m) is provided by just 3 towel rails and a small radiator in an airing cupboard. These are powered by an air source heat pump. Heat is retained due to the airtight membrane, which at last test allows airflow of just 0.4 cubic metres per hour.

The limit for a standard new build is 9 cubic metres per hour.The MVHR (mechanical ventilation and heat recovery) ducting system extracts warm moist air and replaces it with warm fresh air throughout the house. 

The exterior was fully clad in wood fibre insulation, then rendered with a Baumit modern render system. The roof has a large solar array.

There is a polished eco-concrete floor throughout the large ground floor (approx. 120 sq m!) and coordinating this with the flush skirting detail, plus the shadow gap details around the doors was a logistical challenge. The frames are made from Columbia pine (douglas fir). Doors are 8’ in height!

The kitchen was fitted with standard units but finished off with a bespoke bookcase and upstand at the end, and a large panel made from a single, solid slice of sequoia that was felled (out of necessity) in the clients’ previous garden.

All 3 bathrooms have wetroom showers.
