Custom home

A custom home, planned properly and built as promised.

You have the block and a picture of the home you want. We help you turn it into a design you can afford, give you a real number early, and build it at a fixed price with no builder variations.

Pool and spa beside the brick wing of the Warranwood custom home

Fixed price. No builder variations.

Site risks that can't be tested before you sign are listed as a provisional sum, then locked into the fixed price by our third costing round. If you want to change something yourself, you still can, through a formal variation.

A real number in 7 days.

Your QBE gives you a costed figure within 7 days, so you can decide with real information before you spend big on design.

Built to last, specified to perform the way you want.

Comfort, air quality and running costs are planned with you at design stage, to the level you choose.

Designed around how you live

A custom home starts with a clean sheet. We listen to your non-negotiables, your hobbies, your routines and where you’ll be in ten years, then bring in one of our trusted design partners so the plans fit both your life and your budget. Talk to us before you engage a designer, and the design, the budget and the build are planned together from the start.

Priced as the design develops

Through Build Ready, we cost your home at each design stage instead of waiting until the drawings are finished. You see a real number in 7 days, and a fixed price within 4 to 6 weeks of complete documents. No nasty surprise at the end of design.

Built to the level you choose

Want a home that stays comfortable all year with low running costs? We can specify it that way, with airtight construction, thermally broken windows and heat-recovery ventilation. Prefer a well-built home to code? We build that properly too.

What our clients say

Chris & the team at Primebuilt completed a major renovation for our family in Mitcham 2019/2020. The experience from start to finish was first class backed by a quality finish to the Hamptons double story themed home. Honest and reliable building company that delivers!!

karl abel★★★★★ · Google, Nov 2022

Highly recommended. Could not be happier with the overall experience and finish to our house. The whole team was a pleasure to deal with. 10/10 👍

Alex Sowersby★★★★★ · Google, Oct 2022

I couldn't be happier with the end result of my build. Although building through Covid my project was delivered in a timely manner and to a high standard. From demolition to handover Chris and his team were fabulous to deal with and were in constant contact to ask for my input or to work out a solution for one of the inevitable issues that crop up during the building process. I always felt at ease to raise an issue knowing I would be listened too. I have received nothing but positive comments from all who have seen these homes including a building inspector and several real estate agents. I would srongly recommend anyone thinking of building or doing an extension/ renovation give Primebuilt Constructions a call.

Build Ready

How we get you to a fixed price

Tap a stage to see what happens.

  1. 01Intro callAbout 20 minutes

    We talk through your block, your brief, your budget and your timing. If we're not the right builder for it, we'll tell you straight.

  2. 02Discovery meetingIn person

    We meet in person to go through your brief, your block and your budget in more detail, and talk through what's possible.

  3. 03QBE (Quality Build Estimate): a real number in 7 daysWithin 7 days

    Your QBE is a costed estimate for your project, based on your brief, your block and the drawings so far. It's a real figure to plan around, so you can decide before you spend big on design.

  4. 04Design, documents and costing roundsWith our trusted design partners

    We work with one of our trusted design partners (or your own designer) and consultants while final drawings, engineering, soil and energy reports are completed. We re-cost as the design develops, so the number stays real.

    For knockdown rebuilds and new homes, site risks that can't be tested are listed as a provisional sum, then locked into the fixed price by costing round 3. For renovations, unknowns are investigated here, and anything genuinely unforeseeable is shown to you in writing before work proceeds.

  5. 05FQE (Full Quantity Estimate): your fixed price4 to 6 weeks from complete documents

    Once we have complete documents (final drawings, engineering, soil and energy reports), your FQE comes within 4 to 6 weeks. On knockdown rebuilds and new homes, it's a fixed price with no builder variations.

  6. 06Contract and constructionTimeframe set in your contract

    You follow progress, documents and decisions in your own client portal, and questions get a reply within one business day. If you want to change something, you can, through a formal variation, so you always see the cost before you agree.

  7. 07Handover and aftercareYour keys, then checks at 30 days, 90 days and 12 months

    We walk you through the finished home and hand over everything you need to look after it.

    We come back for complimentary checks at 30 days, 90 days and 12 months after handover. If you'd like ongoing help after that, an optional aftercare programme is available.

FAQs

Common questions

Should I talk to you before I engage a designer?

Yes, ideally. The best results come when we start together on a clean sheet. We work with trusted design partners, so we can bring the right designer in for your brief, block and budget, and cost the design as it develops so it stays within reach. If you already have a designer, we work alongside them.

What does "no builder variations" actually mean?

Once you sign, we don't come back with extra costs for things we should have picked up. Site risks that can't be tested before signing are listed as a provisional sum up front, then locked into the fixed price by our third costing round. If you decide to change something yourself, you can, through a formal variation.

How long does a custom home take to build?

Every home is different, so we don't quote a standard build time. Your construction timeframe is worked out during Build Ready and written into your contract.

Do all your homes have to be high-performance homes?

No. Some clients choose a high-performance spec, and many choose a home built to code. We build both properly. See our performance page for what a performance spec includes.
