    Northvale adds floors to retirement flats: design and phasing notes for engineers

    First reported on The Construction Index

    30 Second Briefing

    Northvale Construction is delivering a £7m airspace extension to Trickett House in Sutton, adding two floors to the rear block and one to the front to increase capacity from 49 to 68 retirement flats, with handover of the rear block due in 2026 and overall completion by October 2027. The scheme creates 19 net-zero-carbon homes using air source heat pumps, solar PV, a green roof, SuDS and low-energy lighting, while most residents remain in situ. Works also include upgraded communal areas, additional parking, ambient access improvements and new EV charging points.

    Technical Brief

    • Airspace extension adds two storeys to the rear block and one to the front block.
    • Construction must maintain building services and safe access while most existing residents remain in occupation.
    • Net-zero flats rely on air source heat pumps combined with rooftop solar PV for low‑carbon energy.
    • Green roof and SuDS features will attenuate runoff, reducing peak discharge to the local drainage network.
    • Alertacall system installation introduces enhanced telecare/monitoring infrastructure tailored for older residents’ safety.
    • External works include reconfigured parking layout and EV charging, affecting site logistics and utility connections.
    • Funding stack combines GLA grant, CAF Bank loan and internal subsidy, influencing cost and programme risk allocation.

    Our Take

    Within our 235 Infrastructure stories, there are relatively few schemes retrofitting 1960s stock like Trickett House in Sutton, suggesting this £7m air‑rights style vertical extension could be a reference case for other London boroughs facing constrained land supply.

    The financing tag alongside Sutton Housing Society, GLA and CAF Bank indicates a blended public–social lender model, which in our database tends to be associated with net‑zero or ‘fabric‑first’ refurbishments rather than pure new‑build, giving contractors like Northvale Construction a pipeline in complex occupied-upgrade work.

    Delivering 19 net‑zero homes for older people by October 2027 places this project in the smaller subset of our 588 tag‑matched pieces where sustainability is tied specifically to later‑life housing, an area where operators are increasingly using energy performance to manage long‑term service‑charge risk for residents on fixed incomes.

    Coventry Airport £2.5bn gigafactory: enabling works lens for civil engineers

    Plans to convert Coventry Airport into a £2.5bn battery gigafactory have moved a step forward after Warwick District Council’s planning committee approved applications covering early enabling works. The scheme, promoted as the UK’s largest battery manufacturing facility, will require full redevelopment of the existing airfield, major groundworks and new utilities to service large-scale process buildings and logistics areas. Civil and geotechnical teams can now progress detailed design for earthworks, foundations and site infrastructure ahead of main construction approvals.

    M62 Ouse Bridge joint replacement: fatigue and detailing lessons for engineers

    Contractors will return to the M62 Ouse Bridge over the River Ouse this weekend (13–14 December) to replace a damaged expansion joint installed only a couple of years ago, following an unexpected bolt failure earlier this year. National Highways plans to complete the joint replacement under a short-duration closure to minimise disruption on this key trans-Pennine route between junctions 36 and 37. The repeat intervention on a relatively new joint raises questions over detailing, fatigue performance and inspection regimes for heavily trafficked motorway bridges.

    GE Vernova Hitachi BWRX‑300 GDA: design and civil works notes for engineers

    UK regulators have advanced the GE Vernova Hitachi BWRX‑300 small modular reactor through the Generic Design Assessment in record time, signalling strong early confidence in the 300MWe boiling water design. The BWRX‑300 uses a simplified, natural‑circulation reactor concept derived from the ESBWR, with modular construction intended to reduce on‑site civil works, shorten programme durations and standardise below‑grade nuclear island layouts. Rapid GDA progress is likely to accelerate site‑specific geotechnical investigations, deep excavation design and nuclear‑grade concrete specification for potential UK deployments.
