Henry Brothers Mallusk MOT test centre: layout and capacity notes for engineers
Reviewed by Tom Sullivan

First reported on The Construction Index
30 Second Briefing
Henry Brothers has completed a £13.5m Driver and Vehicle Agency MOT test centre and administrative building at Mallusk, Northern Ireland, designed for 100,000 vehicle tests per year. The facility incorporates a ten-lane testing hall with seven ramp-based lanes for light vehicles, two lanes for heavy vehicles, a dedicated motorcycle bay, an internal road network, car parking and an off-road motorcycle driving test track. Delivered on time and within budget, the layout is intended to support higher throughput and future changes in vehicle testing requirements.
Technical Brief
- £13.5m capital cost sets a benchmark for regional test-centre scale and specification.
- Henry Brothers acted as main contractor, coordinating both the MOT facility and administrative building delivery.
- Ten-lane hall configuration allows segregation of light, heavy and motorcycle testing workflows within one enclosure.
- Dedicated off-road motorcycle driving test track requires specific pavement geometry and safety clearances for manoeuvres.
- Internal road network geometry is tailored to heavy-vehicle turning radii and safe queuing away from public roads.
- Co-location of administrative offices with testing operations reduces inter-building traffic and associated circulation requirements.
- On-time, on-budget completion suggests effective risk management around programme, inflation and supply-chain volatility.
- Design emphasis on “future-proofing” implies structural and M&E allowances for evolving test equipment and vehicle types.
Our Take
Within our 806 Infrastructure stories, relatively few Northern Ireland schemes are in this project-cost bracket, so the Mallusk facility is likely to be one of the more significant recent public-build investments in that region’s transport testing estate.
A 10-lane configuration for the new MOT test centre suggests DVA is planning for higher throughput and resilience in the North, which may allow consolidation or rebalancing of testing capacity across Northern Ireland over time.
