3A Yalgoo Ave, White Gum Valley WA 6162

Imagine living in a home that is naturally cool in summer and warm in winter, with the true comfort of hi-tech eco-design, impeccable environmental credentials and dramatically reduced running costs. Add to that a serene leafy setting near the golf course, and a flexible layout for inter-generational living or income. A one-bedroom apartment at the front is easily part of the home or independent with its own access; the spacious master suite is secluded at the rear, a private courtyard embraces the northern sun, and a rear lane leads to the double garage and workshop space. Created in the award-winning White Gum Valley sustainability estate, this is a brilliant opportunity in a special community.

Flourishing native verges full of trees and birdsong curve around the front of the home, with natural stone cladding adding colour to the exterior. Inside, the polished concrete foyer leads to an independent living zone with kitchen, sitting room, bedroom and bathroom, with side exterior access. Clean contemporary design flows from the foyer into the open-plan, with ply feature walls and sliding doors to the northern alfresco which includes outdoor benchtops and sink. The brilliant kitchen also connects to the outdoors through a servery, and is fitted to the highest standards: finger pull-opening cabinetry in black, white and oak finish; induction cooktop; stacked wall ovens, and stunning benchtops in engineered stone with a rusted metal effect. Through a sliding barn door is the master-suite in sleek industrial design: generous bathroom with spa bath and open rainshower; fitted walk-in-robe, and a western balcony for the sunsets. Also on ground level is a theatre room or gym, laundry, and third toilet. Upstairs is yet another flexible zone, with a bedroom, bathroom including w/c, and sitting area with coffee station and sink – perfect for a teen retreat.

This is one of the few homes in WA built to full German Passivhaus standards, on the five principles of high-performance glazing; timber-framing to eliminate 'thermal bridges'; airtight building envelope; high-quality insulation, and heat-recovery ventilation for air quality. Security cameras, 5k solar power, high-performance Kömmerling UPVC windows and doors with low-e double glazing; 5000L water tank, connected to toilets and laundry, and wi-fi controlled reticulation are all in place.
