Morgan Sindall Aylesbury school expansion: design and safety notes for engineers
Reviewed by Tom Sullivan

First reported on The Construction Index
30 Second Briefing
Morgan Sindall Construction has begun a £13m expansion of Kingsbrook School in Aylesbury, adding a 2,300 m², three-storey block to increase capacity from 1,080 to around 1,440 pupils by moving from six to eight forms of entry. The scheme delivers 20 classrooms, new science labs, food preparation rooms, enlarged SEN provision and additional sixth form study and social space, supporting growth from the surrounding Kingsbrook housing development. A traditional steel frame with precast floors is being used for rapid erection, with segregated worksites and a dedicated access tunnel to maintain safe pupil routes to sports facilities.
Technical Brief
- Site establishment was timed for the October half term to avoid pupil–construction interface during set‑up.
- Construction activities are fully segregated from school operations, implying dedicated hoarding, access control and exclusion zones.
- A temporary tunnel through the works area maintains a protected pedestrian route to sports facilities.
- Proximity to a live school environment drives strict separation of plant movements from pupil circulation routes.
Our Take
Within our 730 Infrastructure stories, Morgan Sindall appears frequently on UK education schemes, suggesting Buckinghamshire Council is leaning on a contractor with a strong track record in live-school expansion and associated safety phasing.
Designing Kingsbrook for up to 10 forms of entry but only building out to eight at this stage gives Buckinghamshire a staged-capacity option; in other school projects in our database this approach has reduced both disruption and rework when local housing growth outpaces forecasts.
A £13 million, three-storey teaching block with 20 classrooms places this Aylesbury job in the mid-range of UK school expansions in our coverage, where contractors often use repeatable modular or standardised components to keep programme and safety risks down on constrained, occupied sites.
