Willmott Dixon’s Passivhaus Cranleigh Leisure Centre: design and delivery notes for engineers

30 Second Briefing
Waverley Borough Council has appointed Willmott Dixon under a pre-construction services agreement as preferred contractor for the GT3-designed Cranleigh Leisure Centre, to be built to full Passivhaus standards. The scheme targets around a 60% reduction in operational energy demand versus a typical UK leisure centre, with GT3 applying its “People Architecture” approach and prior Passivhaus leisure experience. Detailed planning will run through to an anticipated site start in early 2027, with construction logistics focused on maintaining access and parking until the planned autumn 2028 opening.
Technical Brief
- Pre-construction services agreement enables Willmott Dixon to influence buildability, sequencing and risk pricing before main contract.
- Detailed planning phase will lock in programme and construction methodology ahead of the early‑2027 site start.
- Collaborative design development between Waverley Borough Council, Willmott Dixon and GT3 is intended to de-risk later change.
- Construction logistics planning explicitly prioritises continuous public access and retention of parking capacity during works.
- Minimising disruption during the build will likely constrain laydown areas and temporary works options on the existing site.
- Operational energy demand cut of c.60% implies substantially upgraded envelope airtightness and thermal bridge control versus legacy stock.
Our Take
Willmott Dixon’s secured order book of £1.37bn and cash-positive, debt-free position in mid‑2026 (from our recent coverage) suggests Waverley Borough Council is placing this Passivhaus leisure scheme with a contractor that can carry long pre‑construction and design phases through to the 2027 start date with relatively low balance‑sheet risk.
The 60% operational energy reduction target at Cranleigh Leisure Centre aligns with Willmott Dixon’s recent run of public‑sector work for councils and the Department for Education, indicating that local authorities are increasingly using major frameworks and repeat contractors to push higher energy‑performance standards into community buildings rather than treating them as one‑off exemplars.
