The development is the first major application of pre-assembled modular SIPs (structural insulated panel) construction for social housing in Scotland. All 32 homes were pre-assembled in the factory and transported to site with 2 pre-built modules per house.

The trusses were then added on site allowing all properties to be wind-and-water-tight in just 22 days. The homes comprise two and three storey family homes, as well as cottage flats.

The bulk of the pre-fabrication work was carried out in a pop-up factory in Livingston, Central Scotland, where the homes were assembled into an entire module per floor, complete with windows, doors, finishing joinery and undercoat of paint. These were then transported to site, where they were lifted into place by a crane.

This method of construction ensures that the build is not delayed by weather and that quality control can be more strictly managed with reduced wastage. All homes are built to achieve full Silver Active Standard under Section 7 (Sustainability) of Scottish Building Standards.

Anderson Bell Christie and Adston are also working together on 46 homes on a second site in Duns using the same modular system.

Earlier this month, Adston joined forces with SFHA for a visit to the factory and to Berwickshire Housing Association’s site for its members.

Helen Forsyth, BHA chief executive, said: “With the bulk of the work conducted off-site at the Adston factory in Livingston the construction period is greatly reduced, with less disruption to nearby residents. Delays due to poor weather are largely avoided and the quality control is second to none.”
