ISG has secured its latest win with Aviva Investors, taking an £11 million scheme to refurbish Pinnacle House in Wimbledon.

ISG will transform the outdated façade of the existing building, replacing the roadside brickwork and glazed elevation with a striking scalloped curtain walling design.

Internally, the building will be comprehensively stripped back to a shell and core state, with ISG carrying out extensive structural works, replacing cores, creating a new central staircase, installing lifts and delivering new mechanical and electrical services infrastructure.

Significant alterations will be made to the main entrance and public realm space, with a new ground floor reception area created.

Stuart Deverill, ISG’s Southern regional managing director, commented: “This transformational scheme will revitalise an outdated property asset in the centre of Wimbledon into a stand out office development, with a significant increase in rentable space and a striking new exterior.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.”
