Building a home or assessing a site is a major decision. We help clients understand the practical path forward before too much time, money or energy is committed.

Paid builder feasibility reports NSW
Buying land, planning a duplex or looking at a knockdown rebuild? Get a builder's view first.
Our builder-led feasibility reports are a paid service for land buyers, knockdown rebuild clients, brokers and agents who need practical cost, buildability and project information before committing to a purchase, finance application, design pathway or development idea.
Each report is prepared from the information available at the time and is designed to give clients a clearer builder's view of the opportunity, risk areas and due diligence items before they rely on the numbers.

What the report looks at
Useful detail before the site, design or finance decision gets too far.
Feasibility reports are not a fixed construction quote, legal advice, valuation or approval. They are a practical builder-led review to help clients understand what needs to be checked and whether the project direction appears realistic.
Land, constraints and known site issues
Review of supplied site information, likely constraints, services, access and buildability items.
What may need checking
Planning controls, authority considerations, design controls and consultant confirmation items.
Indicative build and project allowances
High-level cost ranges, known allowances, abnormal risks and stress-test thinking where useful.
Value assumptions and evidence
Available local evidence, sale assumptions, resale risk and where agent advice should be confirmed.
What could move the numbers
Items such as registration timing, services, engineering, approvals, GST/tax structure and escalation.
Clear due diligence actions
A practical list of what should be confirmed before purchase, finance, design or construction decisions.

About Solid Building Group
Local, family-owned, licensed and led by real building experience.
Solid Building Group is led by Frank Solitro, a licensed builder with extensive experience across carpentry, detailed joinery, survey engineering, construction technology, commercial projects, international procurement, site management and residential construction. Frank also brings formal study in building and construction, survey engineering and energy-assessment related training.
The name matters. Solid Building Group was built from the Solitro family name and the standard Frank expects on site: solid work, clear advice and a finished result clients can stand behind.
His background includes running building-related businesses, managing teams, coordinating high-quality commercial joinery work, working with overseas supply chains and managing construction delivery on major projects. Today, Frank's focus is close to home. Solid Building Group brings that broader industry experience back to local residential clients across the Illawarra and South Coast.
That mix of experience gives clients practical advice across buildability, cost, detail, site conditions and project risk, helping homeowners, buyers and project partners plan better, build with confidence and make better decisions before they commit.

Building questions
Common questions from land buyers, homeowners and project partners.
What areas does Solid Building Group service?
We work with residential building clients across the Illawarra and South Coast NSW, including Wollongong, Shellharbour, Kiama, Dapto, Albion Park and surrounding suburbs.
Can you help before I buy a block of land?
Yes. Our paid builder-led feasibility reports help buyers understand likely build cost ranges, buildability risks, planning items and checks to complete before moving too far with purchase, finance or design decisions.
Do you work on knockdown rebuilds and duplex ideas?
Yes. We help clients review knockdown rebuild, duplex and dual occupancy ideas, including practical risk areas that can affect cost, approvals and project direction.
Is a feasibility report the same as a fixed quote?
No. A feasibility report is early-stage builder-led advice based on available information. It helps clients understand the project before they commit to a full building contract, tender or finance pathway.
