Enabling works expected to uncover Roman and 13th century remains

Walsingham House ISG

ISG has won a £22m contract to modernise and extend a 1930s office building close to London’s Fenchurch Street Station.

Located in a conservation area, the Walsingham House office block lies opposite the Grade I listed St Olave’s Church and adjoins a four star hotel.

The enabling works and archaeological investigation on the scheme are expected to uncover historical remains including sections of a Roman road and structural elements from the 13th, 16th and 17th centuries.

The upgrade to the building will see ISG demolish the interior structure but retain the stone façade.

Two new floors will also be added to the existing eight-storey building to create nearly 50 per cent more internal office space.

To achieve the targeted BREEAM Excellent rating, ISG will upgrade glazing with high performance units sympathetic to the original art deco window designs.

Matt Blowers, managing director of ISG’s UK Fit Out and UK Construction South business, said: “As prime office locations continue to attract high rental yields, property owners are increasingly looking at all options to increase capacity and provide modern layouts to maximise portfolio yields.”
