About the project

Originally built in the 80’s, One Portsoken Street is located on the edge of the City of London. Oktra were selected to refurbish and revitalise the entire building by Alfred Equities, a forward-thinking developer with the foresight to recognise the incredible potential of One Portsoken Street, and the vision to utilise a construction method that reduced the developer’s risk while achieving practical completion in record time. 

They pushed the boundaries of design and build by gutting the building and filling what was once the largest atrium in Europe. The project included a nine-storey atrium infill, complete with the installation of 27 piles at a depth of 20m. This interior optimisation has led to a 20% increase in lettable space without having to build any extra floors. Floorplate sizes range from 10,000 to 30,000 sq ft and are designed to accommodate up to three separate tenants who will benefit from high exposed ceilings and superb natural light filtering throughout the building, improved destination control with nine new lifts, and a striking lobby space with a two-and-a-half-storey atrium.
