Meeting House Lane Passivhaus
Anne Thorne Architects have just completed a compact newbuild Passivhaus project in York. The project, built by local contractors Croft Farm Construction, is a finalist in the Urban category for UK Passivhaus Awards 2016.
21° collaborated closely with the project, providing: construction advice and training; PROGRESSION Passivhaus-certified windows; the PAUL Focus 200 MVHR heat recovery ventilation system; airtightness and insulation products.
Background
The project is a 144m2 3 bed detached L-shaped house, tucked away between old and new houses in York. Overlooking was a major constraint in the conservation area site. The house is faced with York handmade bricks and corbelled brick reveals have been used to reduce overlooking on some of the elevations.
Construction advice
The client opted for brick and block cavity wall construction for the project and the project team benefited from Green Building Store’s experience in this area, building upon their experience of wide cavity wall masonry construction at the Denby Dale and Golcar projects. Construction details were discussed and agreed with 21° Director Bill Butcher, with a determination not to ‘reinvent the wheel’. Members of the construction team attended a training course at 21° to learn about the building method’s used at the UK’s first cavity wall Passivhaus at Denby Dale.

Windows
PROGRESSION Passivhaus-certified windows with cork insulated frame and narrow sightlines were specified for the project. The PROGRESSION range has a whole window U value of 0.68 W/m2K and was chosen because of GBS reliability as a supplier and commitment to responding to queries and resolving any problems over the longer term which might occur.
