Squire & Partners has submitted plans to turn one of Britain’s oldest breweries into a £1.25bn mixed-use development on a 200m stretch of the Thames.

The project, on the 9ha site of the Stag brewery in Mortlake, south-west London, proposes a new high street, 667 homes, 3,000sq m of office space, a 1,200-pupil secondary school and a care home.

The project would open up what is currently a large inaccessible area between the towpath and Mortlake High Street and will contain 3.6ha of green space.

Beer is said to have been brewed on the site since 1487 when it was part of a monastery and later supplied British troops in India and the Crimea.

More recently it was owned by Watneys, which renamed it the Stag bewery, and then by global drinks giant ABInBev which produced Budweiser there. Production ceased in 2015 when it was sold for £158m to Singaporean developer Reselton.

Michael Squire, founder of Squire & Partners, said the practice had spent 18 months working with Richmond council planners, the GLA and residents to create a scheme that would be a “valuable addition” to the local community. The design was developed in line with Richmond’s 2011 development brief for the site along with national planning policy guidance.

“As a result of its generous mix of uses, the scheme enriches the wider area rather than delivering an independent housing estate disconnected from its existing context,” he said.

The scheme proposes a high street with 20 units for shops, bars, restaurants, a gym, hotel, cinema and rowing club.

The 667 homes will range from one- to four-bed properties and will have underground parking. The developer said the ratio of private to “affordable” will be “subject to viability”.

The care home, offering dementia care, will be part of a care village containing 150 assisted living units.

The school will include a football pitch accessible to the community, a gym and other sports spaces.

The office space will be earmarked for existing and new local small businesses, said Squire.

The scheme will also include improvements to the massive South Circular road junction at Chalkers Corner to mitigate the additional trips generated by the proposed development and improve air quality.

The developer is in the process of appointing project managers to handle the pre-demolition, strip and demolition works and the ongoing phased construction of the project.
