Carlton House Terrace
Clivedale employed Erith to undertake a complex cut and carve project at 20 Carlton House Terrace, located in the prestigious area of Westminster. The site was surrounded by high-net-worth neighbours, including several embassies.
We meticulously carried out the soft strip, asbestos removal, strategic installation of multiple tower cranes, partial demolition, roof removal, removal of multiple segments of floor plates and reconstruction of the eight-storey split level basement into four new basement levels to facilitate new design requirements. This consisted of piling works throughout the basement floor plate, and temporary works including an access ramp to relocate the live car park in both the temporary and permanent positions.

Phase two of the project comprised further demolition to the four-storey basement area and construction of the new structure, including three cores and various floor plates.
The project faced several site constraints, including party wall and retained elements, restricted access to site, embassy parking allocation directly in front of the southern elevation, pedestrian access requirements to Cockspur Court, vehicle access requirements for the car park in the basement, and the retained structure. Further constraints included live businesses, adjacent residencies, student accommodation, neighbouring offices, adjacent hotels, commercial properties, and surrounding building sites. We produced and implemented a robust project-specific neighbourhood liaison strategy to engage with local business group representatives, neighbours in the surrounding area, and key stakeholders.
In-house capability
Due to the requirement of the basement car park to be kept live and in use during the works, we provided innovative logistical solutions through continuous engagement with the design team, client, and relevant stakeholders. We were able to phase the works to retain as much car parking as possible throughout the life of the project.
As part of our commitment to sustainability, we used HVO fuels to power our modern fleet of plant and haulage, resulting in a significant reduction in carbon emissions from the works (circa 75%).
This project exemplifies our commitment to precision, collaboration and environmental responsibility whilst demonstrating our ability to answer the requirements of the modern-day design world.
