Open home: Victorian industrial building being converted to low-energy home - 3:30pm

Visit an 1890s industrial building near Lancaster that’s undergoing a deep retrofit and conversion into a very low-energy home. It was once the battery house for a Victorian hydro plant, which had powered the industrial estate that was on the site of the current Lancaster Cohousing development. (See below for a separate opportunity to visit this innovative housing scheme.)

The project is a work in progress. Here are some of the features that are in place or planned:

  • The building’s solid stone walls have been retrofitted with a new external stone wall skin and full-fill insulation
  • Diathonite lime and cork insulation on internal walls
  • Vaulted ceiling with overlay insulation above the rafters
  • Blower-proof paint on airtightness layer and vapour barrier on ceiling
  • Raising floor level to incorporate insulation and overlay underfloor heatin
  • New built extensions, one with a green roof
  • Doors and windows with high energy performance from the Green Building Store
  • Mechanical ventilation and heat recovery (MVHR) system
  • Air-source heat pump


Things to know before you book...

Accessibility: There is a short walk to the house from the very limited parking space near the site. This is a live building site and is not wheelchair accessible.

There are two time options for this open home visit. This booking is for the 3:30pm slot.
Book for the 1:30pm slot instead.
