The project was a joint venture between the owners of two duplex apartments. The ground floor apartment has gained a dining room and courtyard garden, while the upper floor apartment now opens out to a covered deck. A shared double carport was built with a motorized sliding gate.
The carport features hardwood posts with specially designed steel brackets carrying the roof beams. The timber beams and rafters are kiln dried Australian Hardwood. The roof material is twin-wall polycarbonate sheet, chosen to retain as much light as possible in the courtyard garden directly south of the carport. The roof water is collected in a slim galvanized steel rainwater tank that doubles as a screen to the courtyard.
The upper floor deck is made from LVL floor beams, with fibre-cement sheet, waterproof membrane, and Blackbutt decking to form the floor. The balustrades are flat plate steel frame infilled with 40x25mm Blackbutt slats on edge & on flat, creating an effective privacy screen. Blackbutt was also used for the roof framing, which forms a butterfly roof supported on a steel portal frame. Polycarbonate roofing was chosen again to maximize light and highlight the timber structure.
Sliding door systems and windows are bespoke joinery items, all made from Blackbutt, including a deep reveal and kitchen bench detail to the opening into the upper floor apartment. Blackbutt off-cuts from the construction were laminated together in strips to form a wide slab that has been used as part of an entry canopy to the upper floor apartment.
All the timber has been finished with Sikkens “HLS & Filter 7” and “Cetol” Decking Oil.
The project is an example of a finely crafted and detailed solution to enhance the living environments for two small apartments, giving separation and privacy with increased amenity for a modest budget.
