From kitchens and bathrooms to full renovations and custom new homes - every job open-book. You see every cost, line by line, not a lump sum.

The quote comes in low. The variations arrive quietly. The trades are whoever was cheapest that week, calls go unreturned for a fortnight and nobody can tell you what has actually been spent. That is the part of building that costs people sleep, and it is the part we set the business up to fix - on a bathroom just as much as a new home.
The job we do most. Waterproofing done properly, and a finish that lasts.
Extending out, opening up, or reworking a house that no longer fits.
Custom builds, including from hand drawings that need resolving first.
Hardwood decks, pergolas and the outdoor rooms a coastal house needs.
Smaller structural work, done to the same standard as the big jobs.
Most builders show you a photo. We would rather show you the job - including the parts that went sideways.

Master Builders Victoria Nominee 2026Daniel and Alanna came to us with hand-drawn plans and a tight block. Six months later they had a double-storey home built to the boundary, with every change to the job priced in writing before it happened.

Blairgowrie
An addition, alterations, decking and a carport on a coastal block - started in August and handed over before Christmas, despite finding something under the ground that was on no plan anywhere.

Frankston
Two rooms in one job: a compact ensuite and a main bathroom built around a window the client found. Ordinary 600 by 600 tile throughout, and it does not look ordinary.
Read the write-upSend the same drawings to five builders and the prices can come back nearly $200,000 apart. That is not five opinions about what your house is worth. It is five different sets of assumptions, and only one of them survives contact with your build.
Why quotes differ
01
Not a single lump sum, but every costing, line by line.
02
Scope changes get priced and approved by you before the work happens. No surprise line items at the end of the job.
03
The person who quoted your job is the person who runs it, which is the only reason the open-book part is worth anything.
From first questionnaire to handover, with the timeframes and commitments spelled out.
“The project came in on time (pre-Christmas as was promised) and we love the result. We found them incredibly trustworthy and reliable”
“Communication was clear and timely. Will be returning as a client for further renovations. Very happy client.”
“Came out to look at job and provided a very competitive quote. Did a quality job and would certainly recommend to anyone.”
“Incredibly happy with the service and professionalism Josh and Nathanael brought to our home. Both were friendly, knowledgeable and were clean with their work.”
“These guys are top notch!! They knocked up my brand new build within 6 months, and there isn’t a thing out of place… excellent craftsmanship and professionalism.”
Josh and Nathanael met at youth group, apprenticed together, and started Prominent Builders on the Peninsula. Josh is a registered builder, Nathanael a qualified carpenter working toward his own registration, and both are on the tools and on your site - backed by their own crew of apprentice carpenters and a carpenter.
We build across 15 suburbs, mordialloc to portsea, and further for the right project.
You see the numbers we see. Trade quotes, allowances and any variation go to you in writing before the work happens, so the only surprises are the ones you choose.
Josh or Nathanael. Josh is a registered builder; Nathanael is a qualified carpenter working toward his own registration. Both are on the tools and on site, backed by their own crew of apprentice carpenters and a qualified carpenter. You are not handed to a project manager you have never met.
No. Kitchens, bathrooms, decks and small extensions are as much a part of what we do as full renovations and custom new homes. Same crew, same open-book pricing, whatever the size.
Domestic Builder Unlimited (CDB-U 75629) and Commercial Builder Low Rise (CCB-L 100254), so new homes, renovations, extensions and small-scale commercial are all covered. We carry $20 million public liability cover.
It depends on the size of the job. Kitchens, bathrooms and smaller work are usually 4 to 6 weeks out. Full renovations and new builds are more like 3 to 4 months, once drawings and permits are done. You will get our real next available slot at the first meeting, including when that is further out than you would like.
Mordialloc to Portsea, and further for the right project. These are the suburbs we have completed work in:
A few questions about the site, the scope and your timing. If it is a job we are the right builder for, Josh or Nathanael will come and look at it.
No obligation. If we are not the right builder for your job, we will say so early.
