The Quad 7 building, part of the office precinct being developed by Auckland International Airport Ltd, used the Vantage 175mm Structural Glaze system with a number of customised adaptations to achieve the design objectives of Warren and Mahoney Architects.

Vantage Windows and Doors manufacturer, Wight Aluminium, installed the panelised 175mm system with double glazing on the building's upper floors and single glazing on the recessed ground floor facade. Three different glazing adapters were developed to ensure the ground floor windows maintained a flush plane with different glass types and thicknesses.

To ensure structural support for the 6.4m-high ground floor mullions, these were bracketed to steel beams behind, which were then placed within a colour-matching aluminium sleeve (Duratec Matt Black powder coat used throughout). The ground floor panels were 2.4m wide and were the biggest ever made by Wight, with each weighing approximately 900kg.

Wight extrusion supplier, APL Window Solutions, also developed a special 90-degree corner mullion for the project as well as vertical aluminium sun control fins (80mm wide x 750mm deep) which spanned the upper floors at each end of the 70m-long building.

The NZIA jury citation for Quad 7 stated that, "this floating, black, glazed box is a slick and smooth addition to a growing commercial and retail district near Auckland Airport. Open at both ends, and without a back, the elegant yet unapologetically commercial building is spatially generous to both users and pedestrians, and detailed with precision."

Quad 7 is five green star-rated and was built by Macrennie Commercial Construction Ltd.
