This custom-designed 7-star energy-rated home in Moriac is one of our standout sustainable builds. Finished in September 2021 and featuring stunning rammed earth walls, burnished concrete floors, and UPVC double-glazed windows and doors, the home blends warmth, durability, and modern efficiency. Natural timber accents add texture and charm throughout, creating a calm, welcoming feel.
Designed with passive solar principles, this all-electric home stays naturally cool in summer and warm in winter, minimising energy use while maximising comfort. Built for a growing family, this project reflects everything we value: thoughtful design, sustainable materials, and high-performance construction.
Nestled in a quiet coastal street in Anglesea, Misty’s House is a calm and considered transformation of a much-loved weekend escape. Once cold and ageing, the home has been reimagined into a warm, efficient, and low-maintenance retreat, preserving the relaxed spirit that made it special to begin with.
Working closely with Alex English Architecture and the owners, the project focused on thermal performance, long-term durability, and a grounded, budget-conscious approach. The result is an all-electric home constructed from lightweight materials on concrete footings, designed for year-round comfort and simplicity.
