Marvel Homes, an innovative NSW-based residential construction company founded by brothers Mo and Ibrahim, specializes in building affordable certified Passive Houses that address critical challenges like energy efficiency, climate resilience, and healthy living environments. The Warrawee Passive House, soon to be certified, exemplifies the company’s commitment to sustainable and accessible homebuilding.

Located on Sydney’s Upper North Shore, this 305 sqm home was designed to meet the needs of a family of five while overcoming the complexities of a battleaxe site. These challenges included the unique site shape, sloped terrain, council approval requirements, and heritage regulations due to its proximity to the renowned Exley House by Harry Seidler. The design features five bedrooms, three bathrooms, and a striking 2.5m cantilever. Marvel Homes led a collaborative approach involving clients, engineers, Passive House consultants, and town planners to create a home that is both functional and energy-efficient.

The Warrawee Passive House achieved an impressive air tightness of 0.41 ACH and is currently undergoing Passive House Plus certification. Marvel Homes’ ‘Lean Passive House’ approach was integral to the project, enabling the construction of an affordable Passive House on a budget of $1.15M (excluding landscaping and approvals). This method simplifies structural solutions to eliminate thermal bridging and integrates Passive House principles throughout the design, reducing overall construction costs.

Warrawee Passive House stands as a testament to Marvel Homes’ vision of making sustainable, energy-efficient homes accessible to more families, offering a model for future-focused design that prioritizes climate resilience and affordability.
