We do things differently
We understand that when it comes to building, renovating, or extending your home, you don’t want any surprises. So, we do things a little differently.
Rather than offering estimates and price ranges at quote time, then charging you extra for variations, we take the time required to compile a comprehensive Bill of Quantities for your custom home or renovation.
We’re also committed to helping you finesse the building proposal until it meets your budget.
This gives you the peace of mind that comes with a fixed-price contract, but with all the typical benefits of a custom building experience.
And that’s not the only part of our process you’ll appreciate…

What is the Preliminary Phase and why does it matter?
The Preliminary Phase is the 5-stage process Mamet runs before any building contract is signed. It covers feasibility, planning, engineering, full BIM modelling, and council certification. We sort out every detail before you sign — so your fixed-price contract is exactly that: fixed.
What is a Feasibility Consultation and what does it include?
A meeting (in-office or online) to understand your vision, followed by an AI-generated property report covering council regulations, site constraints, easements, overlays, height and size limits, build-over checks, and indicative
costings from HIA and CoreLogic data.
What is a Bill of Quantities and how does BIM produce one?
A line-by-line cost breakdown of every material, trade, and labour item in your build. We use AI-assisted BIM to convert your 2D plans into a 3D model, from which an accurate BOQ is generated automatically. No guesswork. No surprises.
It’s why we can guarantee a fixed price.
What does the Preliminary Agreement cover and what does it cost?
A Master Builders contract that engages Mamet to coordinate your Preliminary Phase. Not a building contract. You deal directly with each professional (surveyor, architect, engineer) — eliminating the builder’s margin on those fees.
Mamet’s fee: $0.
How will I stay informed during my home build?
You’ll have a personalised online portal and app with your plans, engineering, selections, schedule, and photos from day one. Your site supervisor updates it throughout construction. Scheduled site visits at key milestones. Before
handover, a detailed inspection and walkthrough with you.
