Several other councils are interested in the Sunesis branded off-the-shelf schools, with a potential £100m of projects in the pipeline.

The standardised schools have been developed by the builder and the building purchasing efficiency group Scape.

Each design will deliver costs savings of up to 30% and has attracted interest from Nottingham, Gateshead and Derby Councils.

Willmott Dixon launched the standardised product range last year under the brand Sunesis to meet the Government’s ‘more for less’ agenda.

Warwickshire has now given the go-ahead to use a Sunesis school to create extra capacity at Oakfield Primary School in Rugby.

The council chose the Keynes model from the Sunesis range at £2.2m, adding in optional extras of internal sliding wall, play equipment and tensile canopy alongside free furniture.

The deal means Oakfield Primary School can buy a new building instead of adding a smaller extension.

From the first inquiry in July last year through to completion in September, the council is saving 26 weeks compared to a tradition bespoke school.

Willmott Dixon start on site this month and complete the project for the new school year.

Peter Owen, managing director for Willmott Dixon in the Midlands and its sector leader for education said: “This is a tremendous moment in the delivery of a new generation of efficient schools that provide an excellent learning environment but at significantly lower cost.

“This is about Willmott Dixon and Scape providing a real solution to councils who want their budgets, already under much pressure, to go even further for what they spend.”

Sunesis delivers pre-designed primary and secondary schools at a fixed price and aims to achieve a cost per pupil of £8,500 – £10,000 against a typical school cost per pupil range of £15,000 – £20,000.
