PROJECT FEASIBLITY
The questions worth asking before you commit.
Whether you're looking at purchasing a site or refreshing an existing property, our team can help assess the potential, highlight any compliance considerations, and provide clear budget guidance for development, construction, or renovation.
Our extensive unique collective experience and knowledge of council regulations, building code requirements, and real-world construction costs has us well positioned to guide you on whether subdividing, renovating, extending, or rebuilding will deliver the most practical and cost-effective outcome.
02 OUR EXPERTISE
Free Site Assessment
If you’re thinking about renovating, purchasing land or already have a property and are not sure what’s possible, then get in touch.
We can arrange a site visit and assess the property’s potential, highlight any planning or compliance considerations, and offer clear advice around how things like terrain, ground conditions, natural hazards and zoning could impact your build
Our years of experience in the industry has given us insight into what works well in particular environments
We have the expertise to suggest design elements and materials that can maximise a site’s potential and the skill to identify potential hidden costs, ensuring you get the best value for your investment.
Renovate or Rebuild?
Love the home you’re in but needs bringing up to date? We can help you weigh up whether renovating or extending is feasible to achieve your vision.
Our understanding of changes to the building code and council regulations over the years along with current construction costs, means we are well positioned to offer guidance on whether renovating and extending an existing property is the most practical and viable approach.
"Our comprehensive Project Management service includes removing or demolishing existing structures to clear the site, through to handing over your finished home."

04 WANTING ADVICE ON SUBDIVIDING
Subdividing?
Have a site with potential to subdivide? Looking to add a secondary dwelling or unlock your site’s full value?
Subdividing and building on your current site can be an achievable and affordable way to downsize (or upsize) into a new home, help children or family members onto the property ladder or generate a secondary rental income stream.
"Our team draws together the necessary expertise to provide advice on the feasibility and likely cost of subdividing your property."

FIND OUT HOW MUCH THIS HOME COST TO BUILD
Before committing heavily to plans and pricing, it’s important to understand whether the design truly aligns with your budget, site constraints, and long-term goals. By engaging the team at Thorne Group early, we can provide practical guidance from both a construction and development perspective to help identify opportunities, reduce risk, and help protect your budget from the outset.

03 FREQUENTLY ASKED QUESTIONS
Speak to people who have actually been through it.
Not one or two, a lot. Over 100 of our Bay of Plenty clients have written about their experience not just the finished home, but what it was really like to build.
Ask them about communication, budget tracking, how we handled challenges, and whether they would build with us again. That feedback earned us Most Trusted Architectural Builder five years running.
Request the essential questions to ask prior clients
Our biggest impact is in the early design and detailing. Co-director Gavin Morrow works with architects to refine detailing for complex builds, optimising structure and labour without compromising intent.
Pricing happens when there is enough detail to be accurate, but before you reach a point of no return. The architect can still refine the design to meet budget, and we can suggest changes to details that may not be visible but can save on materials and labour.
The principle holds whether you are at the upper end of the market or working to a tighter budget. Decisions made early carry the most weight.
People assume we are.
Then they look closer. We believe in upfront, realistic pricing with no surprises. Our comprehensive Building Proposal gives you a detailed breakdown of every allowance and inclusion. Compare apples with apples: another builder's cheaper quote often excludes items or includes costly assumptions.
We've had clients come back after choosing cheaper quotes, only to find their final cost far exceeded our estimate once excluded items and delays were factored in.
Request our Pricing Guide
No. Every home is architecturally designed, bespoke, and tailored to your site, budget, and lifestyle. Set plans often lead to higher costs once adjustments are made.
Custom design, done right, actually saves time and money by working with the site, not against it. We're happy to share examples of homes we have built, along with plans and pricing, so you can see the quality.

We believe the best outcomes come from pairing the right team to your specific project.
We work closely with a select group of trusted architects and designers and can recommend someone that suits your style. Or collaborate with your chosen architect, we're equally happy either way.
It's a one-stop concierge service: one point of contact throughout your entire journey, from start to finish.
Request our Process to Build Guide
No. We have built for numerous clients who are based remotely for their entire build.
Our systems keep everything on track regardless of where you are. You track your project online with a live schedule, access documents, view photos and footage as work progresses.
Your Project Manager stays in regular contact via messaging, video calls, and email. Samples of colours, flooring, benchtops, and tiles can be dispatched so you're confident in every selection, even from afar.

The depth of experience across our team is significant. Aaron worked through complex geotechnical developments, giving him expertise in ground conditions and site constraints most builders never encounter. Gavin built high-end homes in Europe, where the standard of detail and execution is different; that approach carries through today. Pete brought systems and financial oversight from large organisations, shaping how we track budgets, manage communication, and record decisions. On site, we keep teams small and consistent, each led by a foreman with at least 20 years' experience. We have been continously refining our systems for over 20 years
Meet the team
We believe in transparency. Our Building Proposal gives detailed cost breakdowns every allowance and inclusion explained. You can speak to our previous clients and ask how their final cost compared to the original quote. That's where the real story is. For extra peace of mind, we welcome you engaging an independent Quantity Surveyor to price the project independently. We actually encourage that level of scrutiny.
