A new landmark where Old Street meets the City – 

99 City Road involves the retrofit and extension of an outdated 1990s office building into a landmark 36-storey tower, delivering 475,000 sq ft of commercial space. Strategically located at the intersection of Old Street and the City, 99 City Road will deliver a best-in-class occupier experience, combining extensive power infrastructure (6MVA) and flexible floorplates with 45,000 sq ft of premium amenity offering. Occupiers will benefit from a multifunctional event space, wellness and conference facilities, private terraces with 360-degree views, collaborative workspace and end-of-trip facilities with 574 cycle spaces. The building is targeting market-leading ESG credentials, including EPC A, BREEAM Outstanding, NABERS 5, WELL Gold and Smart and WiredScore Platinum*, setting a new benchmark for sustainable workplace design.  

Thoughtful design, lasting impact – 

99 City Road is being transformed through a retain-first approach that preserves the majority of the structure, reducing embodied carbon while creating an adaptable workplace for future needs. The scheme significantly improves the public realm through a generous new public square, widened pedestrian routes, and a publicly accessible ground floor with dedicated spaces for free community use, cultural programming, and curated events. Its compositional design of folded planes responds to the surrounding context, with serrated façades inspired by nearby Victorian architecture, incorporating natural ventilation, improving shading performance, and creating a dynamic exterior expression while mitigating environmental impact. Internally, distributed plantrooms allow maximum space for roof gardens and terraces.
