Central Quay
Central Quay is an award-winning residential development project that was part of a proposed city centre masterplan scheme to facilitate the regeneration of the Central Quay riverside site in Glasgow, located on the banks of River Clyde.
Synopsis
Central Quay is an award-winning residential development project that was part of a proposed city centre masterplan scheme to facilitate the regeneration of the Central Quay riverside site in Glasgow, located on the banks of River Clyde.
Keppie Design (the client and architects) led this project to develop the residential area consisting of 498 apartments and a 20-storey tower.
This multi-system project consists of 35 roof areas across 4 tower blocks, utilising various Bauder waterproofing and landscaping solutions. These include the Bauder Hot Melt system, Bauder Thermofol PVC system, LiquiTEC Balcony/Walkway system, and Bauder Total Roof System (BTRS), expertly installed by Briggs Amasco Ltd.
This residential development is the first of its scale and provides the basis for a sustainable community which will act as a catalyst to encourage further regeneration of the surrounding area.
Central Quay was recognised at the prestigious NFRC Scotland Awards in 2024 for incorporating multiple innovative roofing solutions into one project, achieving the title of best project in the ‘Multi-Discipline Project’ category.

The specification
The specification was to provide a vast and sustainable recreational roof space as part of a residential development plan. Several solutions were considered during the initial design stage, but the design team wanted a robust roofing system to support the various and different types of landscaping. As a result, the Bauder Hot Melt inverted roof system was specified. This is a structural waterproofing system fully bonded to the concrete deck to provide durable waterproofing with the strength and flexibility to cope with the stresses and strains of the new build’s surrounding area. Other Bauder systems of lighter weight were specified for the balconies and canopy roofs.
Another element that had to be considered during this stage was the thermal performance of the roof. Thermal performance for the development had to reach the highest Scottish standards while still maintaining the correct penetrations for the drainage systems and service risers. Various insulations were specified in certain areas of the roofs and therefore adjustments were made to the u-value calculations.
Products applied
- Roof: Hot Melt (Bakor 790-11)
- Balconies: LiquiTEC Balcony/Walkway – LiquiBALKON System
- Canopy roof: Thermofol 1.5mm
Project challenges
The main challenges were the development and design of the flat roof, the installation of the landscaping, and creating access for the residents that would be using the roof space. The main roofs were also very tall, exposing the installers to harsher than normal weather conditions.
BS 6229: 2018 provided another challenge to overcome, as changes to the 2003 edition meant that the best current practice in how to design, specify, construct, install and maintain a flat roof had been re-evaluated and the team had to quickly adapt. For Central Quay’s inverted roofs, they had to factor in an additional 10% to the design thickness of the insulation where a Water Flow Reducing Layer (WFRL) is being relied upon. The roof of any heated building needs to achieve a U-value not exceeding 0.35W/m²K at any point, this resulted in numerous recalculations.

The result
In partnership with Briggs Amasco and Graham Construction, Bauder successfully helped deliver this multi-roof project that required multiple systems. Bauder had been consistently involved in assisting Keppie Design and the full design team to resolve issues on-site. The roof detailing and placement proved more challenging than expected, but through effective teamwork, these issues were quickly resolved. The project’s successful execution ultimately led to it winning the prestigious NFRC Scotland award for ‘Multi-Discipline Project’, highlighting the outstanding collaboration and expertise of everyone involved.
To have been involved in an award-winning project highlights Bauder's exceptional expertise in delivering tailored roofing solutions to highly detailed specifications.
Vinny Fryars, Regional Manager This was an exciting and varied project with different Bauder waterproofing and landscaping systems installed by our experienced roofing contractor Briggs Amasco.
With regular engagement with the design team and main contractor throughout the project, all parties worked together to solve problems and deliver a successful series of flat roofs and podium decks.
They look great and provide vast recreational spaces for residents on roof areas that are sustainable and look great too.
