Situated in the heart of Moorgate, the newly redeveloped Halifax House and two adjacent buildings have become 60 Moorgate – a commercial and retail-led project on the corner of Moorgate and London Wall. We worked alongside PDP London for our client, Thor Ltd.
A new office development set behind a retained, art deco façade
The project consisted of the demolition of the internal structure of three buildings, built between the 20s and 30s, and the erection of a new structure with a single storey deep basement.
In order to provide a truly flexible office space with one extra storey, the drive was to create a column-free area in order to accommodate a wide array of future tenants. A steel frame was chosen for speed of erection with metal decking and concrete slabs acting compositely with the beam to reduce the structural zone.
One of the key features of this project was the retained the art deco façade at 60-64 Moorgate whilst the façade at 60-64 Moorgate was dismantled and rebuilt. 41-42’s façade was dismantled and replaced by a new one. It remains in keeping with the area whilst providing a new, luxury office space and retail units (spread across both ground and basement level). Located close to Moorgate underground station and the new Elizabeth line station for Moorgate, the development is in a prime location in the heart of City of London.
The site presented considerable logistical challenges. Located Bank’s Conservation area on an extremely busy junction. Therefore, the study of the logistics of the site was a key element considered from the beginning of the design stages, together with the sequence for the temporary works.
A key challenge is the site’s proximity to below ground assets including the underground network. The impact of the new structure on the southbound tunnel, which runs approximately 20m below the basement, was assessed and then co-ordinated with LUL. In addition to this, the site sits in an area with great Archaeological interest, located inside the line of the Roman city wall and on the edge of the Walbrook Valley.
