About Build 2.0

Licensed & certified for your peace of mind

When you choose Build 2.0, you’re choosing a builder backed by credentials, experience and an industry-leading guarantee.

Build 2.0 is led by Sam Kortegast, a Licensed Building Practitioner (LBP) a designation reserved for builders who have been formally assessed as competent to carry out building work that’s essential to the structure and weather tightness of residential homes.

Sam is also an approved member of NZ Certified Builders (NZCB) a national association with some of the strictest entry criteria in the industry. Every NZCB member must hold a recognised trade qualification and demonstrate a proven track record of stability, skill and delivering quality results for homeowners.

A safety net for your building project.

As an NZCB-approved builder, Build 2.0 clients are eligible to apply for the Halo 10-Year Residential Guarantee. This is one of New Zealand’s most comprehensive building guarantees, providing much greater protection than both the Building Act and Consumer Guarantees Act. It protects your investment from the moment you sign your building contract and gives you long-term confidence in the quality and durability of your home. Regardless of what happens in the future, your Halo Guarantee will be there to protect your housing investment and help you for the next 10 years following completion of your build. It’s peace of mind, guaranteed.

You’re covered for:

• Loss of deposit

• Non-completion, including remedial work

• Materials and workmanship for two years after building work is complete

• Structural defects for the next eight years from Guarantee Acceptance, including rot and fungal decay (weathertightness)

• Up to 26 weeks alternative accommodation expenses while the house is being repaired

• Automatically transferable when the home is sold, giving any new owners protection too

Please ask us for the Halo 10-Year Residential Guarantee Homeowner Handbook for full details of guarantee coverage, exclusions and additional benefits. All Halo applications must be submitted before building work starts.
