We are Calidwell Homes. We bring residential building standards to your garden.
Proper Structural Integrity
We don't just use thin timber. We use residential-grade insulation and structural framing comparable to a house extension.
Full Connections
Most companies leave you to find an electrician. We trench, armor-cable, and connect everything to your main fuse board.
Complete Landscaping
We leave you with a finished patio, not a mud bath. We integrate the room seamlessly into your existing garden design.
