The Goldsmith Avenue development provides a total of 70 high quality flats in the two, six-storey buildings, built by PMC Construction for VIVID, providing a much-needed mix of one-, two- and three-bedroom flats, with two designed specifically for wheelchair users.
The exterior of the two buildings features a mix of red brick alongside Tata Steel’s Urban Seam Façade in Merlin Grey, which was selected for its aesthetics, increased fire performance and longevity.
Matthew Edwards, associate director at HGP Architects said: “We were looking to create a pair of buildings that offered something architecturally different but still reflected the local area. We looked at a range of options, but the standing seam was the one that best suited the surroundings of former industrial and railway buildings. The grey steel cladding provides an excellent contrast with the classic red brick and creates the sharp lines that give the buildings their character.”
The development was in the planning and design phases during late 2017 and therefore, the design and specification of the façade was influenced by the increased focus on fire safety that followed the Grenfell tower fire in the same year.
Richard Crane, technical design consultant at PMC Construction, explained: “The importance of maximising safety has been underlined in the most horrifying way and with regulations likely to change, we adapted the specification to ensure it surpassed current standards.
“Following a discussion with the team at Tata Steel, they devised a solution that would satisfy the client by minimising the use of combustible materials in the cladding systems.”
The Urban Seam Façade system consists of a high-quality steel standing seam mounted on a profiled steel deck. This steel deck replaces the continuous plywood or OSB backing board usually used in fully supported standing seam cladding. This means the new system has an improved reaction to fire rating of A1 and provides an ideal solution for use on residential apartment blocks. Tata Steel’s technical team also provided installation guidance and assistance in designing site-specific details such as those around the window and door openings.
“A standing seam system that features a metal deck was already in development,” said Gordon Crichton, business development manager at Tata Steel. “When we learnt what was required for this project, it became obvious that the new system would be ideally suited.
“Because of how new this installation method was, it required close collaboration from everyone involved but it has been a real success and is now being used on a range of new projects.”
Durability and the proximity to the coast were also factors in the selection of materials. Located on Portsea island and just over one mile from the Solent, the buildings’ façades had to be resistant to harsh weather and the coastal environment.
Urban Seam Façade is manufactured from high-quality Colorcoat Prisma pre-finished steel, and features a Galvalloy metallic coating for exceptional corrosion resistance. Furthermore, the complete Urban Seam Façade system has been independently tested to Centre for Window & Cladding Technology (CWCT) standards. The large-scale test assessed the system’s performance in relation to wind resistance, impact resistance and water tightness, including dynamic pressure tests.
“We are delighted with the quality of the build at Goldsmith Avenue,” said Mike Shepherd, director of new business and development at VIVID.
“The look and feel of the external fabric is key to the building’s success. It has made a significant improvement to the street scene and will act as an excellent catalyst for future regenerations.”
