At 969 square feet (90sqm), the petite property is the biggest sculpture Cath has ever made and she admits to having got through the project using pure determination. Amazingly, she poured between 150 and 200 aircrete bricks every day, so it's no wonder it took such a long time to build.
The house is formed from four interconnected domes, the largest of which is 14.8 feet (4.5m) tall. Internal, doorless archways lead into each space, creating an expansive, seamless feeling. Inside, there's a lounge, kitchen, dining area, two bedrooms, a laundry and a bathroom.
