New build FAQs
Do I need to own the land before getting a quote?
No — we quote indicatively and can review land before you buy.
Can I use my own architect or designer?
Yes — any qualified architect or draftsperson, or we can recommend one.
How long does a new build take from signing the contract?
Typically 10–16 months contract-to-keys (approvals 4–12 weeks, construction 6–14 months). Detailed program before you sign.
What's included in the fixed-price contract?
Everything on the plans and specifications. Exclusions are clearly listed — typically land, design and council fees, connections, rock excavation and landscaping.
Can I make changes once construction starts?
Yes, via written variation. Minor changes are easy; structural ones can delay and need re-certification.
Do you offer finance or progress payment plans?
No direct finance, but we work with most banks and brokers. Standard stage payments: slab, frame, lock-up, fixing, practical completion.
What warranties do I receive?
HBC insurance, 6-year structural and 2-year non-structural warranties, plus a 12-month maintenance period.
