Kawneer systems supply a quintet of criteria at Greenwich
Windows and doors by Kawneer feature on apartments at Greenwich Square.
Architectural glazing systems by leading UK manufacturer Kawneer were specified for a primarily residential building at the heart of the redevelopment of London’s Greenwich Square for their aesthetic, acoustic, thermal, fire-resistant and sustainability credentials.
Kawneer’s AA®543 open-in windows and AA®540 fixed lights feature in the stairwells of Block 3 – a seven-storey, garden-courtyard block of 325 apartments for Mace Developments that was masterplanned by Make Architects and delivered by KDS Associates.
In addition, Kawneer’s AA®543 windows, AA®540 series of fixed lights and AA®545 doors are coupled together on all elevations and complemented by the thermally superior AA®720 doors and fixed lights on the ground floor entrances.
Work on the £80 million building by main contractor Mace took almost three years and delivers a 6,895m2 mix of studio and one- to three-bedroomed units, 292m2 of commercial space, and basement parking for 195 cars and 600 bicycles.
Part of Phase 3 of the £250 million regeneration of a three-hectare brownfield site, Block 3’s build of concrete frame also utilised off-site methods, with prefabricated bathroom and utility pods.
Nikhil Raj, Associate Director with KDS Associates, explained that Make Architects had been responsible for the whole masterplan of the site which included Block 3 that was developed to Stage 3 level.
He said: “The original scheme was not commercially viable, therefore Mace development appointed KDS to rationalise and optimise the Make Architects’ original scheme. KDS assisted Make Architects in submitting an NMA by adding another storey and an additional 42 units to the existing scheme. Upon receiving a successful approval on NMA, KDS were appointed by Mace Developments to deliver Block 3.
“We needed a slimline and robust look, along with the benefit of better acoustic and thermal performance. Aluminium also played an important part as we wanted to earn some additional BREEAM points.”
He added: “I have worked with Kawneer products before, so it was no surprise that they delivered on their promise again.”
Greenwich Square was a stalled development on Government brownfield land for more than 10 years before Mace, as principal equity investor, worked through the complex issues with a special purpose joint venture company, to finally unlock the site.
The team brought together the numerous stakeholders involved to channel energy around a common purpose – to create a new community for east Greenwich that delivered 50% high-quality affordable housing as a key focus.
The vibrant new destination comprises 686 new mixed-tenure homes and a community hub with facilities including a leisure centre, library, health centre, adult education college and shops, all planned around an attractive town square.
One of the first schemes in the UK to make use of the “Buy now, pay later” land initiatives, the creative social housing model included a pre-sale to L&Q of 314 of the residential units and a commercial transaction with the council for the funding and future management of the Greenwich Centre.
Phase 1 comprised 361 apartments, maisonettes and town houses as well as the public square, GP surgery, leisure centre, public library and retail space, while Phase 2 added 325 studios and one- to three-bedroomed apartments (239 private and 86 affordable).
Sustainability was integral to the design of Greenwich Square, from the design of the apartments and townhouses to the facilities provided for residents. All the homes are designed to Code Level 4 Fabric First for sustainable new homes as well as meeting the Building for Life Silver Standard and CEEQUAL “Very good” for landscaping and public realm works.
Nikhil said: “The key requirement was amendment to Approved Document B. This was not officially published at the time of registering with Building Control, therefore a lot of design changes were anticipated to future proof the building. The project that is delivered is robust and fully compliant in line with the latest amendments to Approved Document B.”
Richard Blakeway, Deputy Mayor for housing, land and property for the Greater London Authority, said: “Greenwich square is a great example of GLA brownfield land being used to build much-needed housing of an excellent quality with fantastic public facilities to boost the local community.”
Greenwich Square won the gold award for best mixed-use development at the What House? Awards in 2015.

Kawneer glazing systems help with a Welsh town’s regeneration
High performance curtain wall and door products by Kawneer feature on the Taff Vale redevelopment in Pontypridd.
Aluminium glazing systems from leading UK manufacturer Kawneer were specified by key supply chain partner DarntonB3 Architecture for the redevelopment at the heart of the regeneration of a South Wales town.
Multiple curtain wall and entrance door products from Kawneer were specified on the three buildings that comprise the £40 million Taff Vale redevelopment in Pontypridd.
Kawneer’s AA®110 capped and SSG (Structurally Silicone Glazed) curtain wall and thermally-superior AA®720 doors feature on several storeys of two office blocks whilst the AA®110 capped curtain wall product has been used on the ground floor of the statement community building.
In addition, Kawneer’s AA®190 TB entrance doors were installed on all three buildings over nine months by a team of up to 20 operatives from specialist sub-contractor Dudley’s Aluminium for main contractor Willmott Dixon. Dudley’s won Willmott Dixon’s “Overall Partner Award” for this project at their Supply Chain Awards.
Rhondda Cynon Taff County Borough Council commissioned Willmott Dixon to develop the ambitious project to kickstart Pontypridd’s resurgence, providing much-needed space for employment and for the community.
All three buildings at Taff Vale share the same reinforced concrete basement and podium design. The two office buildings are similarly designed five-storey, steel-framed blocks. The office-led scheme will boost local employment and increase footfall to Pontypridd town centre, with the ambition of making the town centre more appealing to new businesses.
The main community building containing public facilities, a library, council offices, leisure and fitness centre, retail unit and café, is an architectural feature and is consistently more complex, featuring a curved on plan facade.
Constructed using steel, in-situ cast reinforced concrete, brick, glass, prefab timber units and individually sized and shaped zinc shingle panels, its roof structure is unique and visually impressive.
Its semi-monocoque design curves in two directions via a steel frame which connects to the reinforced concrete core. The frame supports prefabricated timber cassettes that are bolted back to the steel. Thin timber planks are used to form the curves of the façade and individual zinc shingle panels (6,345 in total) are fixed using a clamp to form the outer face.
Creating a project with unique design features comes with its own set of challenges, and unsurprisingly the construction of the façade was one of the project’s most difficult elements. Due to its curvature, the façade angles out in places, creating a two-metre overhang from the base of the building.
The design means there are areas where the windows are almost tilting back on themselves so the importance of efficient drainage was a particular consideration. The mullion-drained Kawneer glazed curtain wall which completes the exterior of the main community building at ground-floor level was also installed at a 16° angle that falls back on itself.
The DarntonB3 project architect said: “Kawneer is known to us. We have used their systems before and would specify them again.
“Transparency in the buildings was important, particularly at ground levels, and the Kawneer curtain walling provided clean, slim lines. Sustainability was also a factor in the selection of building products.”
A sustainable construction practice was designed into the project as an important part of achieving a BREEAM “Excellent” rating. Elements included photovoltaic panels on the roof of the two office buildings, rainwater harvesting tanks in the plant rooms, and the use of several prefabricated, modular elements, such as the timber cassettes forming the community building façade. The project team also made use of BIM to track and measure its progress towards achieving the BREEAM target.
