Victoria & Vine is a New York-inspired apartment development in Collingwood, Melbourne, designed by Cox Architecture and constructed by Hickory. This new upmarket residential property stands out for its site-specific drainage installation with individually measured shower channels installed to eliminate the challenges of unsightly variations seen in standardised fittings, while still adhering to tight installation schedules.

About Victoria & Vine

The project consists of 241 apartments including a $7 million penthouse, with access to a health club, infinity pool, rooftop lounge, co-working space and business lounge. The development is a blend of nine individual buildings with a combined 200m street frontage consisting of 11 retail spaces including food and beverage offerings. This multi-tiered development uses a variety of materials such as reclaimed brick, glazing and pre-cast panels to emulate New York’s meatpacking district referencing the iconic Collingwood Foy and Gibson warehouse.

Drainage installation

Each drainage installation is site-specific while providing the efficiencies of high-volume production

As a premium development, product selections needed to reflect the quality of the entire project. Ensuring the drainage requirements of all bathrooms within the 241 apartments were perfectly met on both aesthetic and performance considerations required attention due to the high detail specifications within this project. Another important element that needed to be considered was the overall service and a production schedule as it needed to fit into this exceptionally tight construction timeline.

Individual attention

In all construction projects there are minor variations – rooms are rarely laid out within 0.5mm of the exact planned dimensions, and doing so would be near impossible just to allow for the perfect fit of an off-the-shelf product, such as a shower channel. Even if this is achieved the designer would have to detail the exact finished dimension of the room at the detailing stage. Wall build-up of linings, membrane, tiles and adhesives would have to be determined perfectly to avoid a huge make-up of silicone, or requiring the tiler to squeeze in a channel that is made too large. This will ruin the aesthetic of the shower channel and the quality of the overall room finish.

The logical solution is to select a supplier that can fabricate the channels perfectly to suit the area in each individual shower, providing the modern appeal of a wall-to-wall channel while navigating the challenges of making an off-the-shelf product fit. Another consideration would be the location of the outlet. In large multi-level projects, there are often structural elements or other services preventing a channel from having a centre outlet. Selecting a custom channel allows for the outlet to be located at a point where a floor waste gully can be installed for ease of piping out, or to suit pre-installed passive fire protection. Products will often need to be made-to-measure on projects that prioritise a high-end finish.

Made to measure

Cox Architects and Hickory are well established companies with a wealth of high-end projects in their portfolios. Experience has given them a grounded perspective on how product and supplier selections can add value to project processes, with service and quality ranked highly. Hickory will review products and share information across their site managers allowing for suppliers who provide excellent service to be used repeatedly throughout future projects. This was a key factor in Cox Architecture and Hickory’s selection of Allproof Vision shower channels. Cox Architecture and Hickory have “been dealing with Allproof for a long time and it made sense to use them again especially with the service we get”, Yianni Psihogos, project coordinator at Hickory said.

Allproof Vision shower channels are manufactured from high-grade stainless steel in off-the-shelf and custom sizes. The channel comes with a VF80 puddle flange, which is designed to fit within a trench created in the subfloor. Waterproofing is dressed into the puddle flange as per AS 3740-2010 Figure 3.9; with the channel installed over the membrane, the channels outlet is directed into the drainage flange.

There are some key benefits to this method: The surface area of the membrane adhered to the flange is greatly reduced over a channel with an integrated flange. This method also allows for the puddle flange to be installed prior to waterproofing allowing all other trades to complete their role without additional delays. The tiler needs to leave a reveal of 80mm plus allowance for silicone where the channel is to be located. Once ready, measurements are to be taken for the channel length and outlet location and sent to Allproof. Upon delivery it just needs dropping into place on a bed of levelling compound with a bead of silicone around the tiles and channel edge. The tiled floor and channel will catch surface water and the membrane will pick up any subsurface water that is able to track through the grout. The membrane then directs sub-surface water towards the outlet through falls outlined in AS 3740-2010 clause 3.4. Should a channel with an integrated flange be selected, this would mean other trades could be held up by the production time of custom length channels for each room as waterproofing needs to be applied to the channel itself.

Rigorous quality control

Following their selection for the project, Allproof provided all required install details along with product training and technical details. Almost 400 shower channels were supplied in phases. Once Hickory completed the tiling in a sequence of rooms, they took measurements and sent them to Allproof.

Allproof manufactured the channels to these measurements, thoroughly checked them through a rigorous Q&A process before clearly labelling each channel with its room number/reference and delivering to site for installation.

Victoria and Vine opted for a wall-to-wall channel; however, the above benefits would also apply to stock channels along with zero lead times and reduced site measures. A solution could be to pull the channel off the side walls allowing for floor tiling either side (potentially 50mm). This means a channel can be ordered well in advance as installers aren’t reliant on getting the final tile-to-tile measurement. Additional economy can be found in utilising stock or standard sizes. One option to accomplish a modern shower design with a stock channel would be to use a tile insert grate, which allows the channel to blend in with the surrounding floor tiles and become a very discreet drainage solution.

The benefit of selecting an established drainage supplier with standardised products over smaller custom fab shops is the ability to draw on tried and tested products. A drainage manufacturer such as Allproof will hold stock in standard sizes and have the production techniques to ensure supply through busy periods of demand. Additionally, drainage manufacturers understand the National Construction Code (NCC), AS/NZ Standards, installation and compatible systems. By selecting suppliers that specialise in specific products, installers can rest assured that the product they receive will be fully compliant, tested to all applicable standards, and suitable for use with robust warranties.
