The contractor is understood to be the frontrunner for phase 3C – the final two buildings designed by Gehry Partners – with the Malaysian-backed developer said to be nearing agreement.

Industry sources said the deal is not yet signed but Sisk has emerged as favourite in what would mark a major success for the firm in the capital.

The pair of blocks will complete the Gehry-designed section of the scheme, known for its distinctive undulating facades, and form the final stretch of Electric Boulevard, the pedestrianised high street at the heart of the development.

The project is expected to carry a build cost of £250m–£280m and includes a substantial basement and podium structure supporting two buildings rising to 15 storeys.

Plans provide for 306 flats alongside 65,000 sq ft of commercial space, including shops, cafés and restaurants, plus a 15,000 sq ft community hub and a 600-space cycle facility.

Sir Robert McAlpine previously acted as construction manager for the first Gehry-designed building at Battersea, Prospect Place.

A start on site is expected within months, signalling renewed momentum at the scheme after a slower period for London residential.

Earlier this month, former Quintain boss James Saunders was appointed chief executive of the Battersea Power Station development company.

He will oversee the delivery of the final 16 acres of the 42-acre riverside site.

Architect Studio Egret West is now reworking the wider masterplan originally drawn up by Rafael Viñoly, reshaping later phases to reflect changing demands for living, working and leisure space.

The revised blueprint is expected to unlock up to 3.2m sq ft of further development across the remaining 40% of the site.

Around £5bn has already been invested since the Malaysian consortium acquired the derelict power station in 2012, delivering more than 2,200 homes, 800,000 sq ft of offices, over 150 retail and leisure units, and the Northern Line extension into Battersea.
