Solid ironbark posts and beams are joined together using exposed steel bolts and brackets to enclose a natural atrium, with ship-lap boards milled from a mixture of ironbark, spotted gum and grey gum. As part of the sustainability principles that guided the design and construction of the house, the timber has been hand selected from the coop and milled in limited volume to produce a high grade product from low grade logs that would otherwise have been wasted. Its western facing carport wall built of granite from the site supports glue laminated beams spanning the double carport space.
Large eaves have been built of exposed timber rafter and batten, allowing the visual texture of the corrugated iron to frame each hardwood clad building volume. The external timber has been finished with a natural borate timber protectant and preservative.
The main living spaces flow freely, their limits defined by structural ironbark elements marking changes in ceiling height. With its exposed wood frame, meranti architraves and yellow box trusses it reads as a demonstration of the construction process. The large open plan lounge, employing unpainted post-and-beam construction, is the most earthy and yet the most abstractly modernist of the houses elements. Two solid victorian ash and tasmanian oak custom made internal staircases service the upstairs guest bedroom and master loft. The LVL floor joists support messmate and spotted gum flooring and deck, surrounded by ironbark balustrade.
The use of timber in this project is exceptional because it makes use of that which would otherwise simply be used as firewood, it shows the story of traditional timber construction in a way that is contemporary and it uses this precious resource as an integral part of an environmentally sustainable, passive solar house for its insulating and structural strengths as well as its’ beauty.
