How Much Does a New Build Cost in Wellington?
Understanding the cost of a new build is one of the most important steps in planning your project. If you are considering building in the region, it helps to know what Kitset home cost Wellington options are currently available. While no two builds are the same, having a clear understanding of what influences pricing can help you make informed decisions and avoid surprises later.
At Wai Build Group, we specialise in new home builds across Wellington, Wairarapa, and the wider region, offering both kitset and turn-key build options. This guide explains how pricing works and what to expect when planning your build.
New Builds – Kitset & Turn-Key Options
What Influences the Cost of a New Build?
New build pricing is influenced by a combination of design, site, and construction factors. These elements determine the overall scope of work and the level of complexity involved.
Key factors include:
- Size and layout of the chosen design
- Site access, slope, and ground conditions
- Location within Wellington, Wairarapa, or Kapiti Coast
- Consent and compliance requirements
- Material selections and level of finish
- Choice between kitset and full turn-key build
Granny Flat Build Costs (Up to 70m²)
Granny flats are one of the most cost-effective ways to add living space, family accommodation, or rental income to an existing property.
Many designs up to 70m² can be built consent-free, subject to site conditions and local planning rules.
General cost considerations:
- Kitset granny flats offer a more cost-controlled starting point
- Turn-key granny flats include full project delivery and coordination
- Site works and services can significantly influence final pricing
Important note:
Final costs depend on site conditions, compliance requirements, and design selections. We provide clear, itemised pricing once these details are confirmed.
Other larger homes
Lifestyle and H-Style Home Build Costs

Cost drivers include:
- Total floor area
- Structural complexity
- Roof form and layout
- Interior and exterior finish levels
- Site preparation and servicing
These builds are typically planned with long-term ownership and functionality in mind.

Why You Won’t See Fixed Prices Online
Online pricing often excludes key components, such as site works, compliance costs, and finish selections. These omissions can lead to unrealistic expectations.
We believe accurate pricing starts with understanding:
- your site
- your chosen design
- your preferred build pathway
This approach ensures pricing is realistic, transparent, and aligned with your actual project.
