The short version
What this report found, in plain English

Three builders quoted on the same job. On paper, Meridian looks cheapest at $612,400. But their quote is missing work that your plans clearly require — demolition and site clearing — and it's not a small omission. That work will almost certainly come back as a variation once the job starts and you have less leverage to push back.

Hartwell at $658,500 is the current lean from this pack. Their quote covers everything in the document pack. The extra $46,100 over Meridian is smaller than the risk you're carrying if those missing items hit mid-build. Written answers on demolition, the rainwater tank and open allowances could change that lean.

Coast & Frame is the most expensive and is missing the rainwater tank — which is a council requirement under BASIX, not optional. This is decision support from the uploaded files, not legal or engineering advice. Before you sign with anyone, send the questions at the end of this report and get written answers back.

Why the cheapest isn't always the cheapest. When a builder leaves something out of their quote, it doesn't disappear — it usually comes back as a variation once work has started and you have less leverage. The real comparison is between complete scopes, not headline numbers.

What we found
Issues to know about before you sign
Demolition and site clearing is missing from Meridian's quote
Your plans show an existing slab that needs to be removed before construction can start. Meridian hasn't priced this. It's not a small job — and it will almost certainly come back as a variation once work begins and you have less leverage.
Estimated risk if not resolved
$8,000 – $14,000
Indicative range only — not a quote. Confirm with your builder in writing before signing.
Missing item
Coast & Frame haven't included the rainwater tank
Your project needs a 10,000L rainwater tank and pump to meet your BASIX certificate. This isn't optional — it's a council requirement. Coast & Frame's quote doesn't include it.
Estimated risk if not resolved
$6,000 – $8,500
Indicative range only — not a quote. Confirm with your builder in writing before signing.
Council requirement
Coast & Frame's roof tiling is an allowance, not a fixed price
An allowance means the builder has estimated the cost but hasn't committed to it. If tiling ends up costing more — which it often does — you'll be charged the difference. Ask them to fix the price before signing.
Estimated risk if not resolved
$4,000 – $9,000
Indicative range only — not a quote. Confirm with your builder in writing before signing.
Allowance risk
Meridian's electrical scope doesn't clearly include solar rough-in
The plans and inclusions show solar rough-in as part of the electrical scope. Meridian's quote is ambiguous about whether this is included. Get a written yes or no before you sign.
Needs clarifying
Hartwell's kitchen is fixed price — the others are allowances
Hartwell has priced the kitchen cabinetry and benchtops at a fixed $32,000 with a selections schedule attached. Meridian and Coast & Frame have used allowances. Hartwell's approach gives you more certainty at the point of signing.
Worth noting
Before you sign
Questions to send to your builders — in writing
Send these by email so you get written answers back. Once the contract is signed, these questions become much harder and more expensive to resolve.
1
Meridian: Does your quote include demolition of the existing concrete slab and removal of all spoil from site?
This is shown in the plans but not priced. If it's missing, you're looking at $8,000–$14,000 as a variation once work has started.
2
Meridian: Is the solar rough-in included in your electrical price? Please confirm in writing.
The inclusions require it. If it's not in the quote, you'll pay for it as a variation — typically $1,500–$3,500 depending on the system.
3
Coast & Frame: Your roof tiling is quoted as an allowance. Can you provide a fixed price for supply and installation of all roof tiling, ridges, hips and valleys?
Allowances leave you exposed if material costs rise or the quantity is underestimated. A fixed price protects you.
4
Coast & Frame: Your quote doesn't include the 10,000L rainwater tank and pump required by your BASIX certificate. Can you confirm whether this is included, and if not, provide a price to add it?
This is a council requirement — it cannot be left out of the final contract without a BASIX amendment.
5
All builders: Please list any items in your quote marked as provisional sums or allowances where the final cost could change during the build.
This forces each builder to be upfront about where cost risk still sits — before you sign, not after.
