Alexandra Buchanan Architecture

Pottsville

Cudgera Creek, New South Wales

Pottsville, perched atop a dramatic ridgeline, this refined off-grid hilltop house redefines contemporary rural living through a deeply site-responsive architectural approach. Designed as a private retreat, the residence balances refined simplicity with robust environmental performance, creating a home that is both highly resilient and intrinsically connected to the Australian landscape.

Set within a challenging bushfire-prone site with a BAL29 rating, the project demonstrates how high-end sustainable architecture can coexist with the realities of the natural environment. A series of interconnected pavilions allows the home to expand and contract depending on occupancy and use, creating flexibility for entertaining, multigenerational living and quiet retreat.

The architecture dissolves the boundary between indoors and outdoors, framing expansive views while maximising cross ventilation, passive cooling and natural light. Careful orientation, deeply considered facade treatments and climate-responsive planning work together to create a comfortable year-round living environment without reliance on conventional energy systems.

Entirely off-grid, the home incorporates sophisticated passive environmental design principles including a central circulation spine that functions as a natural ventilation stack. Integrated solar chimneys draw warm air upward through the building, maintaining thermal comfort throughout the seasons.

This contemporary Australian home is an exploration of sustainable luxury architecture — combining off-grid living, bushfire-resilient design and timeless materiality within a spectacular natural setting.

 

Project details

Conceptual resolution

Early conceptual explorations of the Pottsville House established critical relationships that have been retained in the final design. A strong central axis with views to trees beyond, intriguing courtyard entry and a series of interlocking spaces that all connect to the landscape

Siting

Sitting at the top of the site the Pottsville House is incredibly exposed and we wanted to drive a highly passive approach to the design so very early understanding of the conditions were critical to the ultimate outcome for the project
