Railpen has selected Kier as main contractor for the refurbishment of 100,000 sq ft The Fenner office development in Red Lion Square, Holborn.
The companies are entering into a pre-construction services agreement ahead of a planned start on-site in Q4 2026 with practical completion expected in Q4 2028.
Designed by Stiff + Trevillion, The Fenner will be transformed into a world class headquarters building comprising eight floors of Grade A office space supported by significantly enhanced ground floor amenities and 9,000 sq ft of roof terraces offering panoramic views towards St Paul’s and the West End. Railpen is targeting BREEAM Outstanding, EPC A, and Nabers 5* ratings for the project.
Parminder Singh, development director at Railpen, said: “Railpen is one of the most active investor-developers in the UK and, while every project is different, we have a common approach to how we most effectively deliver long-term value to our members as a pension fund. In construction, we have a carefully considered approach when it comes to selecting our partners, with regards to things like sustainability and quality of build. For The Fenner, Kier stood out during a very competitive tender process because they share our ethos, have a collaborative approach and have the skills and experience required to deliver the best buildings for our occupiers.”
Graham Potts, regional director, Kier Construction London and Thames Valley, at Kier, added: “Railpen is a new and significant client for Kier, one whose ambitious pipeline and progressive agenda aligns perfectly with our own values and approach. While developing in London is always complex, Railpen’s vision is clear and unifying, and we’re excited to be selected under a pre-construction services agreement to deliver the effective, efficient and sustainable redevelopment of The Fenner as a new West End landmark. This agreement marks another milestone in our growing retrofit and repurpose offer in the commercial sector.”
Railpen has appointed Savills and Farebrother as joint leasing agents at The Fenner.
