Hill £45m Merton phase: delivery, safety and low‑carbon design notes for engineers

30 Second Briefing
Clarion Housing Group has awarded the Hill Group a £45m contract for phase two of the High Path estate regeneration in Merton, delivering 147 new homes – nine houses on Abbey Road and 138 apartments at High Path/Pincott Road – within a wider £1bn programme replacing 1,800 homes with 2,800. Demolition of Lovell House and Marsh Court finished in winter 2025, with house construction scheduled for spring 2026 and apartment blocks from early 2027, subject to Building Safety Regulator approval. All new homes will be gas-free, using air source heat pumps and rooftop photovoltaics, with upgraded shared spaces, cycle storage and a re-provided community centre.
Technical Brief
- Gas-free design using air source heat pumps and rooftop PV shifts M&E scope towards all-electric, low-carbon systems.
- Refurbishment of the phase-one courtyard introduces interface risks around access, protection of residents and existing utilities.
- Re-provision of the community centre within phase two adds mixed-use loading, fire strategy and crowd egress considerations.
- Improved shared spaces, landscaping and cycle storage require coordinated drainage, permeability and passive surveillance design for estate safety.
Our Take
Within our 724 Infrastructure stories, very few UK regeneration schemes approach the £1bn scale of the Merton regeneration project, signalling that Clarion Housing Group and Hill Group are positioning High Path as a flagship long-horizon estate renewal rather than a typical infill scheme.
The phasing from winter 2025 demolition of Lovell House and Marsh Court through to early 2027 construction start dates implies a tight interface between decant, demolition and rebuild; on comparable London estate projects in our database this has been a key risk point for maintaining safety performance and resident satisfaction.
The high existing-resident occupation rate achieved in High Path phase one is notable in our regeneration coverage and suggests Clarion’s approach could reduce social opposition and planning friction for later stages in Merton compared with schemes where off‑site decanting has been more extensive.
