Planning granted for BT Building transformation.

81 Newgate Street.

We’re pleased to announce that our project with KPF for our client Tejat V Lux Sàrl, advised by Orion Capital Managers and Pella Real Estate Partners, has received planning permission. AKT II is providing structural, façade and bioclimatic engineering services to the 81 Newgate Street project.


Following a decision from the City of London Planning & Transportation Committee, who also approved our Museum of London project, KPF’s transformation of the former 1980s BT Headquarters will go ahead. Much of the structural frame will be reused, but the massing of the building will be significantly improved to reduce the obstruction of key views.

The building has a wide array of amenities including a gym and spa as well as a restaurant situated on the roof. Through reusing most of the structure, programme has been sped up and also means that this project will be first net-zero carbon enabled office development in London.

“The former BT HQ is one of London’s most unique buildings and we’re excited to be a part of the reinvention of the structure, implementing a ‘retrofirst’ approach for this scheme.” Marta Galiñanes Garcia, Design Director (Structures).

“AKT II Envelopes, our façade engineering team, are sustainably reusing the existing stone cladding, modernising it to create a new, high-performance building envelope.” Steve McDowell, Director (AKT II Envelopes). 

“Our Bioclimatic team worked closely with KPF to design comfortable and safe outdoor spaces at pedestrian, terrace and roof-top levels. Our work enabled us to quantify the benefits of different mitigation strategies, from building massing to balustrade design, extending the results of the wind tunnel tests.” Mattia Donato, Bioclimatic Team Lead.

We’ll be sharing more information on this project as the scheme progresses. Congratulations to all the teams involved for hitting this milestone.
