Project Interiors were instructed by a Purpose-Built Student Accommodation (PBSA) provider, to convert an underground car park into 19 studios and 2 amenity spaces in Leeds. The project presented several immediate challenges due to drainage and structural legacy issues left by a previous contractor. Taking over mid-project, Project Interiors conducted thorough drainage and level surveys, fixed the initial issues, and planned the main works elements.

The team immediately instructed temporary works designers to develop a practical and efficient method for propping and re-construction of the façade, as progress on casting the ground slab and the subsequent critical path activities, depended on the timely demolition of the existing structure and the rebuilding of the lower metre of block and brickwork. Using the internal ring beam at the first floor for support, the team removed and replaced the masonry in 3-meter sections, using a hit and miss approach, ensuring stability while reconstructing the lower brickwork.

Once the external block and brickwork had been rebuilt to the required height, the team prepared the ground and formed casting bays aligned with the newly formed solid ends of the external walls. This phase included the installation of a Sika damp-proof membrane and waterproof tanking to the ground level areas, including the existing lift pits. We also redesigned movement joints into the new slab and carried out the necessary encasement of the existing columns.

The external appearance of the building was a key planning condition and the subject of extensive discussions, requiring our close attention throughout the build programme. The consented scheme involved the removal of the existing arches with masonry infill details and punched windows being installed to match the existing accommodation on the upper floors. The overall look of the scheme relied heavily on this element of works being constructed with precision to ensure no obvious differences where “old” met “new” on the façade.

Internal requirements included acoustic and air permeability testing, extensive fire stopping, and a new MEVP design and installation. Limited ceiling height led to a creative solution: a bulkhead and perforated ceiling system to manage cables and services while providing an illusion of added height.

This challenging project showcased the strong collaboration between Project Interiors and the client’s team. Completing and filling the additional rooms was a rewarding achievement for both parties, after taking over mid-project and overcoming numerous legacy issues. The team’s proactive approach, flexibility with design changes, and consistent communication made project delivery successful.
