The project involved the structural conversion of an existing commercial building, formerly a nightclub, into a mixed-use development with a retained ground-floor commercial unit and six newly constructed residential flats above. To achieve this transformation, significant structural modifications were carried out to reduce the overall dead load and ensure the existing foundations could support the additional floors. The process began with the removal of the existing mansard roof, concrete plank floors at second-floor level, and upper masonry envelope walls, all of which helped lighten the structure and improve load distribution.

A new structural framework was introduced, utilising timber floor joists for the first, second, and third floors in place of the original concrete planks. This choice provided a lighter and more efficient load-bearing solution. The new walls were constructed using a combination of timber framing and masonry cavity walls, balancing structural integrity with material efficiency. Additionally, the existing steel frame of the building was retained and integrated into the new design, ensuring stability while allowing for the necessary alterations.

Given that the ground-floor commercial space remained operational throughout construction, careful phasing and temporary works were required to maintain structural safety and minimise disruptions. The project also had to navigate spatial and structural constraints due to the site's triangular footprint and height limitations. To address this, an “Impluvium” at roof level was incorporated to enhance daylighting while maintaining overall structural efficiency.

In addition to the engineering challenges, the project had to comply with strict planning regulations, particularly due to its location adjacent to a Grade II listed building and within a conservation area. By adopting a design that respected the surrounding historic context while ensuring the feasibility of the new structure, the redevelopment successfully overcame previous planning objections. The result is a structurally optimised, lightweight, and functional mixed-use building that seamlessly integrates contemporary residential flats with an operational ground-floor commercial space, all within the constraints of a dense urban environment.
