Are you a licensed builder?

Yes. Alexim is a QBCC Open Builder (licence 15379101) and a Master Builders QLD member, licensed to deliver every scope of residential construction across South-East Queensland.

What areas do you build in?

We design and build across Brisbane, the Gold Coast and the wider South-East Queensland region. If you have a block in SEQ, we can build on it.

Do I need my own plans?

No. If you own land but don't have plans, our in-house design team will create a home tailored to your block, lifestyle and budget. If you already have approved plans, we'll price and build them.

How is pricing handled?

After design and feasibility we provide a fixed-price contract before construction begins, so your budget is protected from start to handover with no hidden variations.

Do you do knockdown rebuilds?

Yeah, we sure do! We manage the full knockdown rebuild process. Demolition, design, approvals and construction. One seamless engagement under a single team.

How long does a custom build take?

Every build is different, so we give you a clear programme upfront and manage to it in-house from contract to handover. Timing is confirmed once your design and scope are fixed.

The Alexim Advantage

Why Alexim

One aligned team

Land, design, construction and handover under a single roof. No middlemen, no finger-pointing.

QBCC Open Builder

Licensed for every scope of residential construction, from luxury custom homes to knockdown rebuilds.

Fixed-price certainty

Clear, contracted pricing before we break ground so your budget stays protected end to end.

Built to the Alexim Standard

Premium finishes, in-house quality control, and stage inspections against our internal spec.

“Here's the thing — we handle the whole lot ourselves, land to handover. No middlemen taking a cut at every step.

Your money goes into the house. Not into everyone else's pockets.”

Brent, Managing Director

Direct Sourcing Advantage

Premium Without the Markup

ALEXIM sources architectural materials directly from overseas manufacturers. We deal with the factory, not a chain of importers and wholesalers. The savings go back into your build as better finishes and stronger structural specs, at a level that would usually cost far more. Every product is checked against Australian Standards before it reaches site.

Client Experiences

The Standard of Excellence

I hired Brent and his team from Alexim to manage a portfolio of new builds within QLD. I only have positive feedback about the work completed. The projects were completed before the deadline and within budget. I normally have issues with new companies working on my properties and new builds however Alexim delivered. I highly recommend Alexim and will continue to use their services again in the future.

John

Real Estate Owner

I am very happy with this company and recommend them to anyone who is looking for a reliable builder. I recently engaged Alexim to complete a major refurbishment upgrading waterproofing and tiles in our apartment complex in Brisbane. I am very happy with the results and will be engaging them to carry out more work in the future. Thank you Brent and team for your efforts.

Brett

Home Owner

Alexim renovated my bathroom and kitchen, and I am thrilled with the results. Their craftsmanship is outstanding, they were professional and detail-oriented, completed the project on time, and maintained excellent communication throughout. Highly recommend their services!
