Mace has been appointed to redevelop Panorama St Paul’s, BT’s former London HQ, at 81 Newgate Street.
Located in the heart of the City, Mace has been appointed as the main contractor by a subsidiary of a fund sponsored by Orion Capital Managers, to completely remodel the existing structure and extend the building to 13 storeys, creating a new mixed-use destination of offices, landscaped terraces, a retail arcade at street-level and a rooftop terrace with a restaurant and wildflower meadow that will be open to the public.
Working with the existing structure has cut the carbon footprint of the redevelopment in half compared with a full demolition and rebuild, according to Mace, with more than 1,500 tones of Portland stone and granite set to be redesigned and re-used.
Retaining the original building’s core structure achieves carbon savings of 465kg CO2 per sq m and since pre-construction works began in March 2021, Mace and architects Kohn Pedersen Fox Associates, have saved 296 tonnes of carbon by replacing the concrete piles with a more environmentally-friendly steel pile solution.
Ged Simmonds, managing director, commercial offices and residential at Mace, said: “I’m delighted that Mace was chosen to deliver such an ambitious and visionary project. Panorama St Paul’s will be one of the most energy efficient buildings in the city and will set a benchmark not only for future net zero carbon buildings but also for occupier wellbeing. It’s great to be part of this exciting journey.’’
Aref Lahham, founding partner and managing director, Orion Capital Managers, said: “We are committed to creating a new working world that is fit for the future. It is now critical to align the environmental and social values of occupiers to that of the workspace they occupy and with Panorama St Paul’s, we believe that this is a new and relevant addition to the London office landscape that genuinely delivers. It will be a building that cares, for occupiers for whom sustainability, the environment and the health of their staff are priorities.”
John Bushell, design principal at Kohn Pedersen Fox Associates, added: “We’re looking forward to working with Mace on the delivery of Panorama St Paul’s. Working in partnership with an enlightened client, the project addresses many of the most important questions in development today, from environmental responsibility to employee wellbeing and, with the provision of public roof terraces and a cultural destination, how to recreate a thriving city.”
The redevelopment of Panorama St Paul’s, which is expected to complete in 2025, is targeting BREEAM Outstanding for the offices, Wiredscore Platinum and NABERS 5* Excellent rating.
