Custom Modular Homes
Fully custom-designed modular homes. Choose your layout, finishes, and fixtures. Factory-built for precision, then delivered and installed on your site.
Modular Granny Flats
Custom granny flats for family, guests, or extra income. Flexible layouts with quality finishes, designed to suit your block and lifestyle.
Modular Extensions & Renovations
Add space with modular extensions or choose an on-site extension or renovation when modular isn’t suitable. Bedrooms, living areas, ensuites—seamlessly integrated with your existing home and custom-designed to match your style and needs.
