ISG will increase office accommodation space at Pinnacle House by approximately 50% by adding three floors and revising the internal layout. The result should be a 5,200m2 (56,000 sq ft) high-specification office development.
The building will get a new façade, with the roadside brickwork and glazed elevation replaced by a scalloped curtain walling design. Internally, the building will be stripped back to shell and core, with ISG carrying out extensive structural works, replacing cores, creating a new central staircase, installing lifts and delivering new mechanical and electrical services infrastructure.
This job represents repeat business for ISG. It has previously completed office developments for Aviva Investors at Mansfield House and 33 Kingsway and has a current £12m scheme in hand to develop a restaurant in Exeter’s neo-classical Guildhall.
ISG southern regional managing director Stuart Deverill said: “This transformational scheme will revitalise an outdated property asset in the centre of Wimbledon into a stand out office development, with a significant increase in rentable space and a striking new exterior. This latest scheme both strengthens our existing relationship with Aviva Investors and reinforces our specialist credentials delivering complex, structural office refurbishment projects in logistically challenging environments.”
