The bold renovation, being led by Riini Piahana, Founding Director of Coform Architectural Designs, is turning a dated two-bedroom 1980s house into a spacious, light-filled four-bedroom home with an office and double garage.
Currently under construction, the project showcases the clever use of engineered timber to deliver space, scale and style while keeping construction costs in check.
By reconfiguring the home’s layout, Riini has unlocked an additional 40sqm of functional space. The master bedroom has been repositioned, living zones have been restructured to provide a better layout and flow, and skylights have been introduced to draw natural light deep into the home. But the real showstopper? A dramatic sloped ceiling.
Using Prolam Glulam Beams to manipulate the home’s existing trusses, Riini has created a striking architectural void with a deliberate play on angles which enhances spatial perception and makes the home feel even larger.
Five Prolam PL12 H1.2 290 x 90 beams, each spanning 5.3m, were integral to achieving the sloped ceiling and integration of the skylights. While a 4.5m Prolam PL12 H1.2 360 x 90 lintel beam installed above a large stacker door provides critical structural support.
According to Riini, Prolam Glulam Beams offered multiple benefits: “The wide spanning capability and load-bearing capacity of the beams has allowed us to adapt the existing roof structure without a full replacement or the use of steel, which would have made the renovation more costly and less efficient.”
Having specified Prolam across a range of projects, he says he values the product’s versatility and reliability.
“Prolam’s superior strength-to-weight ratio make them an ideal alternative to steel, especially in complex renovation work where both structural integrity and aesthetics are paramount.”
The use of timber also aligns with Coform Architecture’s commitment to responsible design and the use of sustainable materials.
Stay tuned for the full reveal — but already, it’s clear this is a renovation where engineered timber is doing the heavy lifting: adding character and serious value.
