Treehouse by Suzanne Hunt Architect: A Harmonious Retreat in Nature

Nestled in the lush forests of Margaret River, Australia, the Treehouse by Suzanne Hunt Architect is a remarkable example of sustainable residential design. This exquisite 300 m² home was crafted to harmonize with its natural surroundings, offering a serene escape for its owners while maintaining a minimal environmental footprint.

A Dream Realized

The clients, a couple who had spent over a decade in Sydney before returning to Perth, envisioned a semi-permanent countryside retreat that would complement their city cottage. When they found a steep, tree-filled bush block three hours south of Perth, they saw an opportunity to create a sanctuary deeply connected to the environment.

Balancing Constraints and Opportunities

Designing a home within a high-risk bushfire zone (BAL Flame Zone) presented significant challenges. The Suzanne Hunt Architect (SHA) team carefully navigated local planning regulations, including setbacks, building envelopes, and infrastructure limitations. Since the site lacked mains water, sewerage, and had limited power, innovative solutions were required to make the project viable.

To ensure minimal disruption to wildlife, local rangers camped on-site for several nights, assessing the habitat for Carnaby Black Cockatoos and Ring Tail Possums. The team preserved the majestic 30- to 150-year-old Jarrah, Karri, and Marri trees while selectively clearing undergrowth to meet a BAL 29 fire rating. An existing timber cottage, built by the previous owners, was retained and repurposed as an Airbnb rental.

Designing for Longevity and Comfort

The single-level, timber-framed home was designed with aging in place in mind. Its exterior features fire-resistant Spotted Gum cladding, arranged in an uneven vertical pattern to reflect the organic forms of the surrounding trees. Additional materials include Corten steel panels, BlueScope Colorbond roofing, and locally sourced Margaret River stone, which forms the striking fireplace and chimney.

The home’s layout follows an east-west orientation, maximizing natural light and ventilation. Two distinct bedroom wings flank a central living hub, connected by a service core, garage, and expansive outdoor entertaining spaces. The owners’ private suite is elevated into the treetops, offering panoramic views, a cozy snug, a spacious bedroom, and an ensuite with an outdoor shower on a floating deck. A second wing accommodates guest bedrooms and a shared bath, with sliding doors that can close off unused spaces for energy efficiency and privacy.

Seamless Indoor-Outdoor Living

Designed for a couple passionate about entertaining, the heart of the home features a generously sized kitchen with a large island, ample built-in storage, and a dining area that transitions effortlessly into a cozy lounge. Narrow vertical windows frame breathtaking views of the surrounding landscape, reinforcing a deep connection to nature.

Expansive outdoor spaces extend the living areas. A north-eastern deck captures valley views, while a sheltered southwest courtyard—equipped with a pizza oven and built-in barbecue—benefits from cooling summer breezes.

A Self-Sufficient Lifestyle

Inspired by the ethos of self-sufficiency, the couple has fully embraced sustainable living. A thriving vegetable garden supplies fresh produce, complemented by locally sourced food and seafood caught from the nearby coast. They have also planted over 2,000 native species to aid in site revegetation.

The landscape, designed by Damien Pericles, integrates natural rock creeks to direct water flow, enhancing the site’s ecological balance. Off-grid capabilities include a 90,000-liter water tank, an advanced wastewater treatment unit, and a 12kW solar PV system with battery storage. Passive solar design elements, such as strategic ventilation and orientation, further reduce energy consumption.

A Home That Exceeds Expectations

Initially envisioned as a larger residence, budget considerations led to a more compact yet highly functional design. The result is a home that embodies the essence of The Good Life—a retreat where nature, sustainability, and architectural excellence converge. The couple now finds themselves spending far more time in their idyllic Margaret River haven than they had originally planned, embracing the tranquility and beauty of their thoughtfully designed treehouse.
