The Kanda team of John Greenshields, Mark Harrison, Tom Batchelor and Islay Walker were delighted to be part of the exceptional 99 City Road project team assembled by Endurance Land, that last night secured a resolution to grant planning permission by Islington’s Planning Committee for the retrofit and extension of an outdated 1990s office building at the Old Street Junction.

Designed by Kohn Pedersen Fox Associates (KPF), 99 City Road will provide 64,873m2 of adaptable, high-quality workspace within a distinctive 35-storey building. Upon completion, the building will act as an innovation hub – designed to attract knowledge tenants to rejuvenate Tech City.

The main objectives of the scheme’s design include transforming the existing building, upgrading how the building interacts with its neighbours, and greatly enhancing the building’s sustainability credentials.

The majority of the existing building’s structure will be retained, including the foundations and basement. A retain-first approach provides an adaptable workplace while reducing embodied carbon and construction traffic. A new core will be inserted and additional floors added to create a hybrid old/new structure.

The updated building at 99 City Road will greatly transform the relationship the building has with its surroundings and provide tremendous public benefits to the area. The plans significantly improve public spaces around the building through the provision of a generous new public square and widening of pedestrian pinch points.

A publicly accessible, permeable ground floor has been designed for public benefit, including a community makerspace, exhibition space, and a triple-height ceiling great room for curated events. Additionally, 4,320sqm of the building’s office space will be dedicated affordable workspace – effectively doubling the current provision across the London Borough of Islington.

Alongside public benefit, the design places a strong emphasis on sustainability credentials by targeting some of the highest industry standards for a tower redevelopment. Distributed plantrooms allow maximum space for roof gardens and terraces. The compositional design of folded planes responds to context and mitigates environmental impacts. Targeted building credentials include BREEAM Outstanding, NABERS 5*, WELL Core Platinum, and embodied carbon <600kg/CO2/m2.
