The building embodies a dual identity as one of London’s smartest and most sustainable workplaces. Its history influences the market-scaled entrance lobby, whose crafted linings and bold graphics are inspired by J J Mack-era signage. Its architecture is equally responsive to context, particularly the buildings along Charterhouse Street. It maintains the street profile of the listed Port of London Authority building next door, with the base of the building clad in natural stone and upper lightweight glazed storeys stepped back from the street.
In the reception deep tan leather accents and bronze detailing enrich the fluted wall treatment, creating a welcoming impression of craft and space. Reclaimed cast-iron columns found on the site stand either side of the reception. The original building was bombed in World War II, and a plaque acknowledges the casualties of the bombing. Historic photos, juxtaposed with neon artwork by Rob and Nick Carter, express the J J Mack narrative.
The flexible 1500mm planning grid influenced the structural and façade grids and the expression of materials and detailing throughout the building. Exposed services and acoustic panels are set within downstand beams.
An atrium light scoop and artwork, influenced by the J J Mack brand, extends from ground to fifth floor and provides daylight augmented by artificial light along its eastern boundary. Three generous terraces provide spectacular views over London, the City and St Paul’s to the south.
