The Brief
"Create a timeless yet forward-thinking design, close to nature with a spacious and light interior" set the scene and brief for this iconic architectural project. Partnering with designer Bob Burnett and architect Shizuka Yasui, we were engaged to provide structural and geotechnical engineering services for this award-winning, energy-efficient home, including investigations, reporting, design and construction monitoring.
What We Did
Also fondly known as 'The Big Cottage', our structural team designed the cantilever support beams, wall framing, steel gravity beams and steel portal frame bracing on the ground floor. We factored in the large open areas and raised raft foundation to accommodate the unique finished floor levels. The size of the foundation was governed by the architectural look.
Using a combination of timber-framed walls and steel portal frames provided optimal bracing for the house. The ground floor consisted of steel portal frames to create spacious open areas, while a selection of steel and timber beams supported the mid-floor. For the upper roof, we used a German product, GLT (glued laminated timber) panels, forming a continuous panel supported by wall and cantilever glulam beams. To maintain a cohesive aesthetic, exterior beams and posts were crafted from Glulam.
The foundation solution addressed the liquefaction hazard while staying true to the architectural aesthetics. We ensured that large section profiles matched the style, and functional requirements were met (internal insulation and a topping slab). Additionally, we provided structural engineering for the garage wall bracing and foundation design.
