The Upside Down House is designed especially for families who wish to maximise their modern, coastal lifestyle and for those who need flexible layouts to cater for their growing or changing family needs.

Called the Upside Down House because of its reversed arrangement of upper-floor living rooms and ground-floor bedrooms, its configuration allows for greater solar access and better potential to capture views and cooling sea breezes and can be constructed on both sloping and level sites. It is the perfect seaside home.

The Upside Down House focuses on quality rather than quantity is the ideal design solution for tightening budgets. Combined with our standard interior design package or our fully customised fit-out, the Upside Down House is sure to meet all your family's requirements for now and into the future.

As with all Sanctum's pre-designed homes, the Upside Down House follows our principles of adaptability, affordability functionality, sustainability and buildability.


We understand a family home must be flexible enough to accommodate a range of occupants, from newborns to teenagers to young adults to grandparents, as well as those who work from home. The Upside Down House features two distinct, flexible open spaces, which can be easily modified to respond to these changing family dynamics.

Upstairs, the multi-purpose room can be easily rearranged to become a nursery, study, television room or parents' retreat. North-facing covered terraces extend the internal floor areas, while a large, internal light-well floods the home with sunlight in winter and cooling breezes in summer. Downstairs, the rumpus room offers self-contained accommodation for teenagers, young adults or grandparents, or serves childrens' ground floor bedrooms.


The Upside Down House caters to those who are looking for contemporary, innovative design, without the high costs normally associated with 'one-off' building. Together with our preferred builder, we have found many ways to make the house more affordable. The simplicity of its box-like form helps maximise available space and creates an inherent structural efficiency, reducing wastage and avoiding costly, complex construction details.


The Upside Down House suits many site orientations and maximises passive solar heating, natural cooling and ventilation to create natural comfort in and around the home. It's highly insulated envelope uses sustainable, certified products and proprietary building systems to help increase construction efficiency. High-performance window and louvre systems and integrated shade solutions combine to manage the house's energy requirements and limit fluctuations in energy costs and climatic conditions. Optional solar power, grey water recycling and rainwater collection systems further minimise its dependence on resources.
