Open-plan living and dining inside a completed JKC custom home

We don't just build new homes.

Our team is experienced in restoring and extending the existing — house lifts, major renovations, custom homes and commercial, across North & Western Queensland.

What We Build

Four things, done properly.

Structural, complex work is what we do — no bathrooms-only jobs, no off-the-plan shortcuts. Pick the one closest to your project and dig in.

Service 01

House Raising & Build-Under

We lift the house, build the whole level underneath, and hand it back as one finished job — lift, steel, slab and construction managed together.

  • Townsville & Western QLD
  • 4–8 months typical

Service 02

Major Renovations & Extensions

Structural work that changes how your home functions — more rooms, better flow, real floor area. Single and multi-storey extensions, approvals managed end-to-end.

  • Townsville & North QLD
  • 3–6 months typical

Service 03

Custom New Homes

Fully custom homes designed around your block and your brief — never off-the-plan. Steel framing where it makes sense, built to handle what North Queensland throws at it.

  • North & Western QLD
  • 6–12 months typical

Service 04

Small–Medium Commercial

Practical commercial builds for councils, government, education and rural operators — we know how to work in the regions without using metro excuses.

Is JKC the right fit?

We'd rather be upfront than waste your time.

The right fit

  • House raising & build-under projects
  • Major structural renovations & extensions
  • Fully custom new homes
  • Small to medium commercial builds
  • Plans ready or being prepared
  • A realistic six-figure budget in mind

Not the right fit

  • Bathrooms, kitchens or laundries on their own
  • Cosmetic refreshes with no structural scope
  • Sheds, garages or small structures
  • Early-stage ideas with no plans or budget yet
  • Lowest-price, multi-quote shopping
