Custom Level Threshold for Luxury Car Showroom


Selecting a fully compliant level threshold drainage solution is easy with the range of Allproof products available to the market, however some applications can present more of a challenge.

Car showrooms present a tricky scenario; the showroom needs to be presentable with high quality flooring and all the fittings expected when presenting luxury consumer items. However, the vehicles need to be regularly moved between the external forecourt and internal showroom with large doors creating an indoor-outdoor flow. These large openings combined with load class requirements mean that a standard E2 compliant threshold drainage system that has been designed for foot traffic may not be up to the task, and channel systems designed for heavier load requirements are not compliant due to level threshold details such as the required 12mm drip-line along the joinery. Factor in large sliding doors with exposed mechanical runners and a fully level threshold can become a complex task.

Thankfully Wingate Architecture contacted Allproof early on in the process and developed the perfect solution.

Allproof were engaged during the planning phase of Archibald & Shorter’s latest showroom in Wairau Road, North Shore Auckland. Once given a brief, Allproof developed a custom solution utilising components from one of their most popular products, the Perimeter Drain. Allproof created a heavy duty supporting system with the Perimeter Drain preformed channel, combined with a slip resistant stainless steel grate load tested to AS3996. This provided an easy to install, low maintenance fully compliant solution. Allproof also custom manufactured a removable stainless steel cover to hide and protect the mechanical door sliders, providing a seamless entry into the building spanning over four metres. This system creates an aesthetic architectural design, allowing wide openings and large walls of glass joinery to display a stunning collection of vehicles.
