Extending a basement under a Listed building in the centre of London!

In collaboration with party wall surveyors, Quorum used our extensive expertise built over 30+ years of experience to design a basement extension and an additional storey to this high-end London property.

Extending the basement of any building is always a challenge when it comes to coordinating and agreeing construction with adjoining properties. Neighbouring this project’s site was a UAE embassy, meaning that the design and construction methods had to be extensively reviewed to eliminate any risks of structural damage to the adjoining properties as well as limiting noise pollution as much as possible during construction.

Quorum had gone through an extensive process of consultation with party wall surveyors and contractors to agree on a final design, what methods of construction were to be used, and on a suitable monitoring regime.

🏗️ Project in Wimbledon! 🏡

This exciting project is located near Wimbledon Hill Park, on a site where a large, existing residential dwelling was demolished to make way for a brand-new, extensive domestic property. The new construction includes a basement level housing a pool and gym, along with an additional three floors above.

Quorum Consulting Engineers were appointed to deliver the Structural and Civil Engineering design, Construction Management, and CDM coordination for the development.

The basement was constructed using contiguous piling around most of the perimeter, with secant piling in the pool area for added integrity. This was followed by a reinforced concrete inner wall lining, which not only forms the internal structure but also contributes to the waterproofing strategy.

We worked closely with specialist waterproofing contractors to ensure a watertight, robust sub-structure, fit for high-end domestic living.

🏗️ Project Spotlight: Basement Construction for Multi-Property Development 🏠

Quorum were proud to be commissioned for the civil and structural engineering, CDM, and party wall services on this exciting residential development in Streatham Common!

The project involved the construction of approximately 4,000 sq ft of habitable basement space and an additional 2,000 sq ft at ground floor level, forming 4 high-quality homes — each with fully functional basement dwellings.

Our team undertook the design and detailing of the basement construction, working closely with the architect and contractor to coordinate a seamless superstructure. The solution combined load-bearing masonry with a steel beam framework, ensuring both structural integrity and efficient buildability.

From feasibility to ex*****on, we’re proud to deliver robust, safe, and elegant engineering that supports the vision of modern living spaces.
