New social homes for Isles of Scilly: design, access and sustainability notes
Reviewed by Joe Ashwell
First reported on The Construction Index
30 Second Briefing
LiveWest and Nevada Construction will deliver 27 social-rent homes at Carn Thomas on St Mary’s, converting a former school site in the Isles of Scilly where new affordable housing has been absent for years. The scheme, backed by the Council of the Isles of Scilly and Homes England, combines one, two and three-bedroom units with air source heat pumps, roof-mounted solar PV and EV charging. Construction logistics must account for island access constraints, while design targets high environmental performance, biodiversity enhancements and a dedicated solar garden.
Technical Brief
- Conversion of a former school site implies brownfield constraints: existing foundations, services and variable made ground.
- Construction sequencing must minimise disruption to St Mary’s limited road network and port handling capacity.
- On-island storage space is constrained, pushing just-in-time delivery and prefabrication opportunities for structural elements.
- Air source heat pumps and roof PV necessitate coordinated M&E and structural roof load checks in a coastal climate.
- Biodiversity enhancements and a solar garden will drive specific landscape grading, drainage and planting design choices.
- Similar remote-island housing schemes can benchmark logistics planning, off-site fabrication and resilience of low-carbon technologies.
Our Take
Within our 906-item Infrastructure set, the Isles of Scilly appears only rarely, so a 27-home scheme at Carn Thomas signals that genuinely remote UK communities are starting to see the kind of small-scale but strategic social housing infill more common on the mainland.
For LiveWest and the Council of the Isles of Scilly, delivering all 27 units as social rent rather than mixed tenure implies a focus on retaining local labour and service workers on St Mary's, a pattern our database shows in other high-cost island or tourist locations where key-worker housing is under acute pressure.
Homes England’s involvement in a project of this modest size suggests that national funding and standards are being used to de-risk construction logistics for Nevada Construction on the Isles of Scilly, where transport, materials storage and weather windows typically push per-unit build costs above comparable UK mainland schemes.
