Procurement
Following the appointment of the consultant came through open tender via e-tender Wales and Sell2Wales, the design was developed to construction tender stage and the project issued via open tender through E-Tender Wales and Sell2Wales portals. The nature or the project precluded the use of a specific framework in this instance.
Project Overview
The project was brought about by the need to improve the thermal and Solar consequence of the existing 1950’s Crittall steel frame single glazed rain screen system.
The new curtain wall system design has reduced the unwanted glazed areas and provided insulated internal partitions and infill panels, along with the double-glazed system.
The project works were also extended to allow designing and installing a through floor lift for access purposes, also the provision of an insulated EDPM roof covering to the main roof, as another thermal improvement. This included new fascia soffits and rainwater goods.
This transformative project was driven by the urgent need to enhance the thermal performance and solar control of a mid-century educations building, originally fitted with 1950's Crittall steel-framed, single-glazed rainscreen systems. The solution: a bespoke curtain walling system that not only meets modern performance standards but also celebrates architectural artistry.
Design & Delivery
The design component is the key element of the submission. Scoring will place specific emphasis on topics including approach & context, design development, environmental design & sustainability and consultation, engagement & social value.
The delivery process is also an important consideration: Scoring will place specific emphasis on a range of topics including procurement route & technical approach and construction sustainability.
There is a range of other topics which can be included to help give a fuller understanding of the project. These could include subjects like construction phasing, procurement route, technical approach, whole life costing, supply chain, and soft landings.
Projects demonstrating innovation in any aspect of design, construction or delivery will also be recognised.
The new design introduces a double-glazed façade, significantly reducing excessive glazed areas and integrating insulated internal partitions and infill panels. This upgrade delivers substantial improvements in energy efficiency, occupant comfort, and long-term sustainability.
Inspired by the geometric abstraction of Dutch artist Piet Mondrian, the architect embraced a bold visual language—black framing grids punctuated with primary colours and neutral tones. This concept was carefully adapted to the building’s existing structural rhythm, creating a façade that is both functional and visually striking.
A key challenge was the school’s coastal location, which had severely impacted the original steel screens due to exposure to sea air and prevailing northerly winds. The new curtain walling system, constructed with marine-grade aluminium, ensures resilience against harsh weather conditions while maintaining aesthetic integrity.
To achieve the Mondrian-inspired layout, the design required horizontal panel runs that intersected traditional mullion arrangements. This unconventional approach was made possible through close collaboration with fabricators and suppliers, who innovatively modified the curtain wall nosing to accommodate the unique panel configuration.
Safety and ventilation were paramount. Tilt-and-turn opening vents were selected to allow inward tilting for natural airflow while preventing pupil access. The turn function, operable only by staff, facilitates safe cleaning. Restrictors were installed to control vent openings, and high-level clerestory windows were fitted with manually operated cable systems to ensure secure and accessible ventilation.
This project exemplifies how thoughtful design, technical ingenuity, and artistic inspiration can converge to rejuvenate a historic building—enhancing its performance, resilience, and visual identity for generations to come.
