Custom built family home on the Gold Coast by All Leonard Build, with timber, stone and glass facade.
Custom Builds & Knockdown Rebuilds

A new home on the block you already chose.

If your home no longer suits the way your family lives, but the location is exactly right, a custom build or knockdown rebuild keeps the address and starts the architecture fresh. We deliver design aware, builder led custom homes across the Gold Coast.

What it is

Custom builds and knockdown rebuilds are for clients who love their suburb but have outgrown the existing house. We work with your architect, or bring trusted ones in, and run the project end to end from demolition through handover.

Common questions

The questions clients actually ask.

  • It depends on the bones of the existing home. If the structure, slab and layout are sound, renovating is almost always cheaper. If you'd be reworking everything anyway, a knockdown rebuild often delivers better value per square metre and a home that genuinely suits you.

  • Most Gold Coast custom homes we deliver run between 9 and 14 months on site, plus design and approval time. We'll give you a real timeline at quote stage, no optimistic numbers to win the job.

  • Yes, demolition, site preparation, services disconnect and reconnect. You deal with one builder from the day the old house comes down to the day you move into the new one.

  • Absolutely. We're builder led but design aware, we love working alongside good designers. If you don't have one, we'll point you to architects we trust on the Coast.
