New army accommodation in Wiltshire: modular design and energy lessons for engineers

30 Second Briefing
New modular single living accommodation at Trenchard Lines, Upavon has completed its first phase, with Reds10 and Arcadis handing over two SLA blocks providing 82 en-suite bedspaces for junior ranks as part of a 200-person scheme. A further 21 officer bedspaces will come from refurbishment of Lord House, a heritage building beside the Officers’ Mess, integrating modern services into an existing structure. The SLA blocks include drying rooms, shared kitchens and furnished communal areas, plus rooftop solar panels and energy management systems to cut operational energy demand and bolster resilience.
Technical Brief
- Defence Infrastructure Organisation acts as client and delivery body, contracting directly with Reds10 and Arcadis.
- Accommodation is split by rank across separate SLA blocks, affecting circulation, security zoning and services layouts.
- Solar PV and energy management systems are designed to cut operational energy demand and improve supply resilience.
- Shared drying rooms and kitchens centralise high-load MEP plant, simplifying maintenance and energy monitoring.
- First phase handover at Trenchard Lines forms part of the Army’s wider SLA Programme funding stream.
Our Take
Reds10’s role at Trenchard Lines sits alongside its recent leadership reshuffle and new executive chair appointment, signalling that the company is gearing up to scale its industrialised, modular delivery offer across defence and public-sector estates rather than treating this as a one-off scheme.
With Reds10 reporting flat but debt-free finances and £20m cash in its latest results, the Upavon accommodation work appears to be part of a pipeline that lets the firm leverage its balance sheet strength to take on more complex Defence Infrastructure Organisation programmes without overextending.
Arcadis’ appearance here alongside its project management role on the A38(M) Tame Valley Viaduct suggests the consultant is deepening its UK public-sector workload, combining defence estate upgrades in Wiltshire with major transport asset renewals in Birmingham.
