We build new homes, renovations and extensions, and the big rural and industrial sheds working properties run on — plus concreting and selected commercial work. Mark's on the tools. Lee's behind the scenes on layout and finish. And there's a good crew that keeps the standard where it belongs. One licensed builder, slab to handover — so you're not left chasing trades or chasing certificates.
What we build
One licensed builder across the lot.
From the slab to handover, it's our job number and our name on it. Hover or tap a card to see what's involved.
Rural & industrial sheds
Machinery, hay, workshop and lock-up sheds for working properties — slab, erection, fitout and certification handled in-house.
Renovations & extensions
Older homes brought up to standard, and extensions that work with the existing house and the way you actually live in it.
Domestic sheds & outbuildings
Garages, workshops, carports and home-block sheds — built to the same standard as the rural work, just closer to the house.
Concreting
Slabs and concrete work for sheds, homes and standalone rural projects. We're licensed for it, so a proper slab is done in-house.
Commercial building work
Selected commercial projects — small commercial buildings, fitouts and rural commercial work. Practical scope, regional focus.
Sheds
Farm & industrial sheds across the Southern Downs.
A shed's only as good as the build behind it. We work with leading manufacturers for the structure, then handle the slab, erection, fitout and certification in-house — one builder, one job number. Browse the work, and open a panel for the kind of shed that suits your block.
Open-bay and enclosed machinery sheds that keep tractors, headers and gear out of the weather — on a slab built to take the load.
Big-span hay sheds with the clearance and airflow to store fodder properly — engineered for the wind rating your site needs.
Workshops and secure lock-ups set up the way you work — power, lighting, concrete and roller doors sorted.
Larger industrial and commercial sheds for business and owner-occupier sites — built to spec, engineered and certified.
Fully-enclosed indoor riding arenas are a big part of what we do — built with the clear span and height to ride year-round, out of the wind, sun and rain. Plus covered arenas, stables and American barns for working horse properties. Mark's spent years in the equine and rodeo community, so he builds them the way horse people actually use them.
Large-scale commercial poultry sheds, built to spec for serious operations. Mark spent the better part of a decade building poultry sheds across Queensland and Northern NSW — so the experience and the standard are there.

Why Mark Collins Builder
Three quiet reasons it holds up.
A licensed builder, not just a delivery
QBCC 1221102, Master Builders Queensland. Medium-rise, commercial and concrete tickets — so we take on bigger, more complex jobs and do more of them ourselves.
Built for country conditions
Access, weather, ground and freight, and how a working property actually uses its buildings. We've been building out here a long time — we plan for it, not discover it halfway through.

From Mark
You're dealing with the bloke who builds it.
I've been building out here since 2011, and the way I see it a job isn't done when the slab's poured or the shed's up — it's done when you're happy and it's still standing up to the weather years later.
I quote the work, I'm on the tools for it, and I put my name to it. No sales office, no being passed around. If something's not right, you ring me and we sort it. That's the guarantee.
