Turnkey vs Bare Build
Turnkey: Builder manages everything — design, consents, build, and handover. You get a completed home ready to move in. Higher total cost, less involvement required.
Bare build (owner builds or project manages): You contract each trade directly. Can save 10–20% of build cost but requires significant time and expertise. Any errors you manage are your responsibility.
Volume builder: Companies like G.J. Gardner, Signature Homes, Jennian use standardised designs and bulk buying power to reduce costs. Good value but limited customisation.
Custom architect-designed: Highest quality and flexibility. Architect fees add 8–15% of build cost but result in a home designed specifically for your site and needs.
Building in NZ — Key Consent Steps
- Resource consent (if required — depends on zone and design)
- Building consent from your local council (mandatory)
- Foundation inspection before pouring concrete
- Frame inspection before lining
- Pre-line inspection (plumbing, electrical, insulation)
- Code Compliance Certificate (CCC) at completion — essential for resale and finance
Building without consent is illegal and creates serious issues at resale. Your builder will manage consents on a turnkey build.
