Green light for custom-build Passivhaus at Hunshelf Park

Planning has recently been won for a terrace of 10 new affordable custom-build homes aiming for the Passivhaus standard in Stocksbridge, Sheffield by PHT member Paul Testa Architecture.  

Hunshelf Park


The Hunshelf Park proposal aims to create customisable and affordable Passivhaus homes on a difficult site which presents challenges due to its steep slope and proximity to the noise of Stocksbridge’s steelworks. It is rare to have a custom-build Passivhaus project and, to the best of the Trust’s knowledge, this will be a first in Sheffield.


Key Stats

  • No Units: 10 affordable homes

  • Start on site: Spring 2019

  • Completion due: Summer 2020

  • Gross internal floor area: 95m2/ dwelling

  • Form Factor: 2.3 

  • Form of contract and/or procurement:Traditional 

  • Total cost: £1 million

The 3-storey terraced arrangement uses cross-laminated timber [CLT] with detailed timber porches and includes communal parking and landscaping to the front with private gardens and a communal orchard to the rear. The flexible custom-build design will enable residents to adapt both external and internal configurations to match their differing needs and enables future adapts for residents’ changing circumstances.

This is an excellent scheme and I hope it’s very successful and hope there are more like it in the city.


Councillor Robert Murphy, Sheffield Council


Despite the complexity of the project, the efficiency of the design aims to maintain the properties’ affordable selling price while still delivering a good return on investment. The scheme was approved unanimously and was praised by Sheffield Council.

Bringing the Project to Life

Since winning planning the completion date for this project has been brought forward and the aim is now to have the first residents move in by Spring 2020 and the project to be fully complete by Summer 2020, both earlier than originally planned. In order to meet this new target, a rough timeline has been put in place.

Spring 2019: Ground Survey - The first on-site activities will begin with a ground survey. This will involve drilling down into the plot to find out exactly what lies beneath it, a crucial step which will enable the groundworks plan to be formulated.

Summer 2019: Civil Engineering - Getting the groundworks plan in action will involve excavating the foundations and connecting drains and electricity from existing networks. This is also when the ground source heat pumps and sustainable drainage tanks are put in place, and all of this will sit underneath a brand new road and parking.

Autumn/Winter 2019: Building Works - The timber frames will arrive and be put up on site and, depending on to the custom build options chosen, will be finished from anywhere between empty shell and fully decorated.
