When the global security hardware company Allegion shifted premises recently, it didn’t have far to go – its new Avondale HQ is built on land immediately behind the old one, with an even better view across the upper harbour to the North Shore. But while the vista is stunning, the land presented a problem. Used as a tip decades ago, the soil had to be thoroughly remediated before a single hammer was lifted. Over almost eight months of earthworks, Haydn & Rollett’s team shifted 15,000 cubic metres of material to decontaminate the site and prepare an engineered platform for the building.

Designed by Williams Architects, the new building provides high-quality warehousing, manufacturing and administration for Allegion on a sizeable scale. The 4300m2 warehouse incorporates an electro-plating

plant and powdercoating operation, while the 1450m2 two-storey office also includes a showroom, training facility and cafeteria. The front-of-house is heavily glazed to make the most of the view, and the entire site has been generously planted in natives.

While the construction itself was straightfoward, there was a high level of detailing involved and a number of bespoke finishes. Haydn & Rollett played a coordinating role in the design, and collaborated closely with the client throughout the project to ensure that expectations of a high-quality finish were met.

Despite some design additions early on and a ground stability issue that required some innovative thinking to solve, the project was completed on time, on budget and to a standard that all involved can be proud of.
