Studio Pacific Architecture had a clear vision for the design of 155 Beaumont Street Apartments, which is stage two of the 30 Madden Complex. Stainless downpipes for the roof and balcony drainage systems were a key detail that Allproof helped Studio Pacific Architecture achieve.

Studio Pacific Architecture specified 27 locations with 6-7 levels of stainless-steel downpipes equalling about 330 metres in total. Part of the specification required 125mm diameter polished downpipe, an uncommon size in New Zealand. Allproof were able to source the required size and polished it to fit the specified finish. Each section of downpipe was measured on site, designed through a series of shop drawings and then supplied to site ready to install. All downpipes were fabricated at Allproof’s production facility in Auckland on a tight timeline for installation while scaffolding was in place.

The roof drainage was designed as a separate system from the balcony drainage. Allproof’s Sureflow roof drains were used on the building's flat roof design meaning Allproof products were selected to remove rainwater from the roof down to the ground level. Allproof's roof and balcony drainage systems have been hydraulically tested using an independent NATA accredited laboratory to maintain integrity in Allproof’s test data.

The apartments utilised Allproof’s industry-leading Allthrough balcony drainage system. The Allthrough system integrates the balcony drainage through the same penetration as the downpipe as it travels down the building. This removes the need for additional fittings hidden within the balcony soffit and provides an intuitive way to waterproof the balcony and create drainage through one penetration. The downpipe was positioned in the corner against the building to maximise usable space on the balcony, to enable this a small diameter Allthrough base was selected allowing the downpipe to be located close to the cladding.

Inside the Beaumont Street luxury Apartments, the Allproof Invisidrain floor waste was selected for the tiled showers in each apartment providing a discreet NZ made shower drain. Allproof are well positioned to supply the full system for the floor penetrations as their passive fire protection products have been tested for a wide range of scenarios commonly seen in New Zealand. The use of the grate, floor waste and passive fire protection system allows one supplier to take care of the whole penetration for a locally made, tested and easily installed detail.

Multiple developments in Wynyard Quarter have benefited from selecting Allproof products including the award winning 132 Halsey Street project by Athfield Architects, which also used the Allproof Sureflows.

Through 30+ years of manufacturing Allproof have built excellent relationships with contractors such as LT McGuinness and DL Good Plumbers who worked on the Beaumont Street Apartments. These relationships have been built through experience and trust as Allproof consistently deliver premium NZ made drainage systems and provide unique solutions to the New Zealand construction industry.
