The aluminium systems supplier's AA®100 zone-drained curtain walling has been used within rainscreen cladding from the ground to second floors and at the upper floor levels of a courtyard at Tameside One, the second phase of VisionTameside, in Ashton-under-Lyne, Greater Manchester.
The AA®100 curtain wall was also used as a ribbon effect to achieve a punched window design on the external perimeter elevations. This was complemented by Kawneer's series 190 heavy-duty entrance doors, as single and double leaves and open-in and open-out variants.
The £36 million 15,000m2 building designed by international design practice Ryder Architecture comprises Tameside Metropolitan Borough Council's Joint Public Service Centre and an Advanced Skills Centre for Tameside College in two distinct wings, as well as retail units.
In addition to releasing the former 1980s administrative centre from its connection to the Grade II listed Ashton Town Hall, Ryder's design also retains the façade of the Grade II listed former water board building, both improving the setting of historic buildings and enhancing the quality of the public realm around the building and the wider town centre.
The Joint Public Service Centre is a more cost effective and customer-focused building than its predecessor, the new building being half the size of the previous council offices. It also offers improved pedestrian access to the town centre from the station and transport exchange.

The Advanced Skills Centre of approximately 7,000m2 provides state-of-the-art learning spaces for students of vocational subjects including hair and beauty, hospitality, catering, bakery and confectionery, travel and tourism, and business skills.
A number of fenestration options were considered for the six storeys. To the upper office and classroom floors the design features full-height floor to ceiling punched windows on the outward-facing elevations and continuous ribbon-slot windows on the internal elevations.
Externally the fenestration and cladding zones have been broken down into smaller elements to more townscape proportions. The ribbon curtain wall which gives the punched window effect responds more to the neighbouring historic buildings and the large areas of cladding across the external elevations have been broken down into smaller elements at the stair core locations.
A simple and reserved palette of neutral, high-quality materials was selected for the mixed-use development and is paired to the key elements of the building mass to further reinforce a clear expression of use and function.
The brickwork base is punched with Kawneer glazing on the east, south and west elevations forming the shop fronts of retail units. Recessed profiles, expressing a horizontal check at glazing head level, and areas of alternative brickwork bonds reference Ashton's rich history of brickwork buildings.
The main building entrances and the deck level are a continuous surface of Kawneer glazing which is used generously to all publicly accessible areas to promote a welcoming feeling of openness, transparency and legibility of use.
All elements of the building envelope had to achieve pressure test requirement for air permeability of 3cum/h/m2 at 50 Pa.
The Kawneer systems were installed over more than two years (due to Carillion's demise) by a team of up to 60 from specialist sub-contractor/dealer FK Group for main contractor Robertson Construction who replaced Carillion.
Project architect and Ryder director Mark Clasper said: "The Kawneer curtain walling to the ground floor and first floor provides a transparent plinth to the full perimeter of the building while giving views into key spaces of both the library and the key teaching spaces within the college while also providing large amounts of natural light. It met the performance required with regards to the required U-values."
He added: "It's fantastic to see the Tameside One colocation starting to deliver on bringing greater efficiency, economic prosperity and the transformation of learning and skills for the people of Tameside."
