Seaforth, NSW

The Seaforth High Performance House is a custom new build that pushes the boundaries of residential construction in NSW. Designed and built to high-performance Passive House principles, this home achieves outstanding energy efficiency, superior thermal comfort, and exceptional indoor air quality — without compromising on luxury or aesthetic refinement. Located in the sought-after northern Sydney suburb of Seaforth, the home presents a striking contemporary facade of white render, natural timber screens and clean horizontal lines that respond thoughtfully to the surrounding landscape. Large windows and expansive floor-to-ceiling glazing draw in natural light and connect the interior living spaces to the outdoor pool and lush garden beyond. Inside, the home showcases meticulous craftsmanship throughout. The designer kitchen features a substantial stone island bench, warm timber cabinetry, and high-end appliances — a space as functional as it is beautiful. Bedrooms and bathrooms continue the commitment to quality, with a freestanding bathtub, double vanity, custom joinery and premium finishes setting the standard for luxury living. Every material and detail has been selected to complement the home's high-performance ethos. Blaise Building Services delivered this project with the rigorous attention to detail and construction discipline that high-performance building demands. As specialists in Passive House and energy-efficient construction in NSW, Blaise Building Services brings together technical expertise and a passion for craft — creating homes that are built to last, built to perform, and built to inspire.
