Originally designed by John Nash in the early 19th century, Regent's Crescent is an historic site on the south-east corner of Regent’s Park. The building was damaged during the Second World War and reconstructed in the 1960s, but with the addition of a pair of residential blocks at the rear.
The current crescent façade is Grade I-listed, but this relates to its historical presence rather than the existing post-war material. As a result the façade will be demolished and rebuilt with new brickwork and stucco that accurately represents Nash’s original design.
Whilst the crescent is to be demolished, the plant rooms, gardens, and the two blocks with the entrance that runs beneath the crescent are to be retained. In place of the crescent, a series of high quality four-storey residential apartments are to be built, extending beyond the existing façade line at the rear. It will be comprised of a reinforced concrete frame with vertical concrete columns and horizontal flat slabs. Stability is to be provided by new reinforced concrete cores and walls. The new roof structure constitutes a lightweight timber frame made of vertical SIPS panels and plywood diaphragm deck.
Two tube tunnels run under the south-east side of the crescent which place limitations on the extent of new foundation and construction activity. The close proximity to the tunnels also creates noise and vibration issues which need to be mitigated using an acoustic anti-vibration isolation system. Ground movement modelling is also necessary to assess the impact of the new construction on the underground tunnels, particularly the effect of new basement construction.
The structure will utilise either shallow rafts or piled foundations, and two new basement levels have been proposed for both sides of the crescent. In addition, there is an existing sewer running beneath the gardens behind the crescent which could clash with the planned basement, so it will likely be necessary to divert this to the edge of the site.
