The proposals submitted to Bromley Council include plans for 122 new residential apartments, comprising a mix of 1, 2 and 3 bedroom homes, and over 1,500 sqm of high quality office and retail floorspace designed to respond to post-Covid market demands.

The comprehensive redevelopment of the well-known vacant 1950’s office building, which has become an eyesore in recent times, will help bring new jobs and regeneration to Bromley South and deliver much-needed new homes to the area.

The constrained site on the corner of Masons Hill and Westmoreland Road will see two distinct buildings delivered. The taller residential element will act as a local landmark, dealing with the transition in height between the taller buildings around Bromley South to the north and stepping-down to the smaller residential buildings to the south on Sandford Road, Pinewood Road and Cromwell Avenue.

A separate, lower office building on Masons Hill, designed to complement the Grade II listed former St. Mark’s School adjacent, will frame views from High Street and Masons Hill towards a new landscaped courtyard in the foreground and towards Keston Ridge in the distance.

The architecture throughout is refined yet playful, with rounded corners and subtle design features influenced by Bromley’s rich Arts and Crafts heritage.

The development, which will be known as One Westmoreland, will be an exemplar project in the area. Modern Methods of Construction (MMC) and sustainability have been key design drivers throughout. The development will feature on-site renewable energy sources, including solar panels and a state-of-the-art air-sourced heating system that will see a reduction of 60% in regulated carbon dioxide emissions beyond the baseline of Building Regulations, significantly exceeding the minimum required by the London Plan. The building will also incorporate best-in-class building safety systems, including Secured-by-Design accreditation features and stringent new fire safety measures for taller buildings.

Off-site construction technology will be utilised, with a precast concrete superstructure and façade system resulting in a significantly reduced build programme and impact on neighbours, less construction waste and a significantly smaller carbon footprint when compared with traditional construction methods.

The development will also provide the opportunity for significant ecological enhancements and urban greening, with new biodiverse habitats and significant tree planting making One Westmoreland one of the most sustainable developments in the Borough.
