Originally designed by John Nash in the early 19th century, Regent’s Crescent is a 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 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 has been demolished and will be rebuilt with new brickwork and stucco that accurately represents Nash’s original design.
Whilst the crescent has been demolished, the plant rooms, gardens, and the residential blocks with an entrance that runs beneath the crescent have been 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 comprise 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 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 that place limitations on the extent of new foundation and construction activity. The close proximity of the tunnels also creates noise and vibration issues, which will be mitigated using an acoustic anti-vibration isolation system. Ground movement modelling has also been necessary to assess the impact of construction on the underground tunnels, particularly the effect of basement construction.
The new 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.
