The durability and natural beauty of timber features throughout this compact, three bedroom home, which also showcases several structural design innovations.

The distinctive tropical style roof, wide eaves and arched, clear span interior are achieved using specially curved trusses, utilising the economy, natural strength and flexibility of standard pine framing members. Generous gable protection is achieved using durable, small section hardwood purlins.

The low profile floor frame makes efficient use of seasoned pine, LVL and structural plywood flooring, in a simple modular format suitable for prefabrication.

Trusses and twin bearers align throughout, allowing direct support and tie down, even in cyclonic areas, using standard methods. The 1800/2400 truss spacings create useful ceiling spaces and allow lintel free, full height wall openings.

Wall framing and tie down is greatly simplified, with a modular panel system possible. High openings combined with arched ceilings provide quality natural lighting and ventilation as well as perceived spaciousness.

Thermal performance and durability of the external stud walls is enhanced by using hardwood fixing battens horizontally. These firmly secure the reflective foil during construction, reduce thermal bridging and ensure appropriate air gaps are maintained. Softwood framing and plywood bracing is better protected from condensation or moisture penetration of the cladding. Drilling of studs for services is reduced as these can be run behind the studs.

Tinted clear finished Cypress provides a tough exterior cladding and a warm, welcoming appearance. Also chosen for its natural durability and low shrinkage, the 125x25 rough sawn boards were milled locally to a shiplap profile and fixed vertically. This reduces joints and wastage, simplifies installation and improves durability.

Finger jointed Radiata Pine features internally for reveals, trimmings, cornices and ceiling battens, creating a simple, natural feel to the home. This complements the feature Hoop Pine plywood and painted ceilings.
