Castlewood House

An existing mid-20th century building on New Oxford Street is to be demolished and replaced with a new nine-storey mixed use development.

The new steel frame structure will retail units along the ground floor, whilst the rest of the superstructure will be commercial. The complex site also includes existing building which site within a conservation area, and so will be retained and converted into affordable housing.

The site is heavily constrained by rights of light and tube proximity, as the new Tottenham Court Road Crossrail Station is only 120m to the west, making it a challenging project, in both a geotechnical and architectural way. Reducing the foundation sizes was therefore essential, so a lightweight structure was developed. We utilised a steel frame and concrete metal deck slabs to form the new building. An existing two storey basement will be reused and extended in parts to create a larger back of house area.
