St. Modwen has announced it is planning to deliver up to 350 new all-electric homes on the historic MG Rover site that was once home to the MINI in Birmingham.

Powered by a dedicated 'smart grid', electricity will be supplied and tracked across a network of homes to ensure this first phase of homes will be 100% gas-free. The innovation is believed to be the first to be used by a major developer as St. Modwen continues to pioneer sustainable new ways to build and power homes. The smart grid design is being developed alongside SNRG, specialists in next generation energy infrastructure.

This latest move follows the launch earlier in 2022 of St. Modwen's first carbon-negative homes, a landmark trial that makes homes so airtight that they can return power to the UK grid. By using the latest construction techniques and embracing new renewable technologies such as solar panels and heat pumps, the carbon-negative homes are designed to produce more energy than they consume and could reduce a family’s total energy bills by 76% when compared with a standard new-build house. Aspects of this trial will be deployed in the new all-electric homes and in turn across all new developments by St. Modwen as carbon-reducing technology becomes standard.


Outline planning was secured for the Longbridge site in 2021 for a total of 350 new homes. Detailed planning for the first phase is currently with the local authority, meaning new homes are expected to be built by St. Modwen Homes from the Autumn 2022.

The vast site in South Birmingham is boosting the local economy, with 7,500 new jobs expected over the coming years in Longbridge. Adjacent to the new all-electric homes, work has started to create a large veterinary hospital, creating over 100 new full-time jobs. Further new employers are anticipated to move to the area, including a global science business, as it becomes more established as a leading hub for science and technology, medicine, advanced manufacturing and R&D.

The site has been made possible following £20 million of infrastructure investment in partnership with the West Midlands Combined Authority (WMCA). Longbridge has been extensively regenerated with homes, retail, education and green spaces delivered to date. On completion of the regeneration, St. Modwen plans to create a total of 3,000 new homes, 2 million sq ft of commercial floorspace and up to 10,000 jobs at Longbridge.
