Hillside and Warrender Primary School Expansions

Two Energy-Efficient Schools Delivering Additional Places Across Hillingdon
Sinden was appointed by the London Borough of Hillingdon to deliver the expansion of Hillside Infant, Nursery and Junior School and Warrender Primary School as part of the borough's £150 million programme to increase capacity and meet growing demand for pupil places.
Across the two schools, the projects delivered more than 3,400m² of new teaching accommodation, including 20 classrooms, specialist learning spaces, halls, kitchens and support facilities, alongside improvements to existing buildings and extensive external works.

Both projects involved the delivery of substantial new teaching accommodation, improvements to existing facilities and extensive external works within live school environments. At Hillside, the sloping site presented additional engineering challenges, while both schemes required the delivery of modern facilities with minimal disruption to pupils, staff and day-to-day school operations.

Our Approach

Careful planning and phasing were essential to maintaining safe and effective school operations throughout the works. Regular communication with the school community and local residents helped keep stakeholders informed and ensured any concerns were addressed promptly.

At Hillside, the site's challenging topography required the new building to be constructed over split levels, with a substantial retaining wall incorporated around the new Multi-Use Games Area (MUGA). Accessibility was also a key consideration, with a purpose-built ramp providing inclusive access across the hillside. The staff car park was redesigned and a new drop-off facility introduced with dedicated one-way access routes to improve traffic flow and reduce congestion around the school.

Outcome

The completed projects have provided Hillside and Warrender with modern learning environments that support growing school communities and create additional pupil places across the borough. New teaching accommodation, enhanced learning spaces and improved external facilities have created high-quality environments for pupils and staff, while accessibility improvements have made the schools easier to navigate and use.

Sustainability was a key consideration throughout both schemes, with automated lighting controls, passive ventilation strategies and photovoltaic systems incorporated to reduce energy consumption and support the schools' long-term environmental objectives. The result is two energy-efficient schools that will continue to serve local communities and support Hillingdon's educational needs for years to come.

"It was a pleasure working with the Sinden team throughout the work on our new building. The team made sure we were involved and able to make key decisions and the attention to detail and quality of work was excellent. Local residents even commented on how impressed they were with the cleanliness of the road and how considerate Sinden were.  The children and staff are all really proud of our new school building and enjoying the new learning environment."
