New Garden Quarter, East London
2nd June 2020

Aluminium building systems supplier TECHNAL and installer Ravenworth worked together to deliver a £4.2m project for Telford Homes, New Garden Quarter, including windows, patio and entrance doors as well as curtain walling.

The development, which sits next to the Queen Elizabeth Olympic Park, features one, two and three-bedroom apartments, villas and sky villas set around a landscaped two-acre garden square.

Project architect, Pollard Thomas Edwards Associate, Eleana Kontou explained: “The brick built eight-storey blocks feature uniform frontages broken down into a varied set of neighbouring buildings.

“The facade systems and materials generally have been selected to give the space a calm and civic character, whilst acting as a backdrop to the dramatic square’s landscape.

Facing the main square, the facades are punctuated by inset and Juliette balconies featuring Technal DF 75 Si Tilt-Before-Turn windows and C125 patio doors. The top two floors are setback duplex penthouses with private roof terraces.

Telford Homes technical coordinator, Martin Conroy, said: “One example of this collaborative approach was the large 4m2 panes of glass on the balconies. To ease installation and maintenance, the spans were split with a transom and installed in line with the balcony itself so that the glass still looks like one pane.”

The Technal aluminium façade systems selected met a host of regulatory requirements. These included the Building Control Body and National Housebuilding Council (NHBC), Lifetime Homes and London Housing Design Guide compliance, as well as Secured by Design (SBD) for the main entrance doors at the client’s request.

Thermal performance was also a priority with the overall U-value for all windows set at 1.4 w/m2k. Manufactured as floor to ceiling windows by Ravenworth using Dualframe 75 Si TBT, these aluminium tilt-before-turn windows are an ideal solution for this type of application, combining ventilation with easy cleaning and the capacity for large span openings.

To achieve the 38 dB RW+Ctr value specified by the acoustic consultant, an acoustic glazed coating was incorporated along with glazed-in acoustic trickle vents on the monorail patio doors. These are Technal’s thermally insulated C125 patio doors, which are built in to the floor to achieve a low threshold for easy access. Realising the architect’s vision, in addition they satisfied the client’s requirement for a monorail configuration that is SBD compliant.

Also, meeting the requirement for PAS 24, Technal’s Dualframe 75mm Dualsecure doors have been installed on the terraces and balconies throughout the New Garden Quarter development, whilst Technal’s STII doors create automated entrance openers for easy access to each block.

At ground floor level, Technal’s E52 curtain walling has been used to create the shopfronts for this mixed-use development, which incorporates retail and leisure facilities as well as services such as a children’s nursery. Likewise, the stairwell facades have been installed using E52 in different spans, up to seven floors.
