Renovation Cost in Wellington in Wellington
- Hillside sites. Many Wellington homes are on steep sections that make access, scaffolding, and material delivery more expensive and time-consuming.
- Older housing stock. Wellington has a high proportion of pre-1980 homes that often contain asbestos, lead paint, and substandard wiring, all of which need remediation before renovation can begin.
- Earthquake considerations. Many renovations trigger requirements to bring the existing structure up to a higher percentage of New Building Standard (NBS), adding engineering and structural costs.
- Wellington weather. High winds and rain days can extend project timelines, particularly for exterior work and additions.
- Trade demand. Wellington's tight labour market means skilled trades are in demand and priced accordingly.

How Much Does a Renovation Cost in Wellington?
If you are planning a renovation in Wellington, the first question on your mind is almost certainly: “What will this actually cost?” It is a fair question, and one that most builders avoid answering directly.
We are not going to do that. Below you will find realistic cost ranges for common renovation types in the Wellington region, based on our 28 years of building experience. These figures reflect 2026 market conditions, including current material costs and trade rates.
Why Do Wellington Renovations Cost More Than Other Regions?
- Hillside sites. Many Wellington homes are on steep sections that make access, scaffolding, and material delivery more expensive and time-consuming.
- Older housing stock. Wellington has a high proportion of pre-1980 homes that often contain asbestos, lead paint, and substandard wiring, all of which need remediation before renovation can begin.
- Earthquake considerations. Many renovations trigger requirements to bring the existing structure up to a higher percentage of New Building Standard (NBS), adding engineering and structural costs.
- Wellington weather. High winds and rain days can extend project timelines, particularly for exterior work and additions.
- Trade demand. Wellington's tight labour market means skilled trades are in demand and priced accordingly.
How to Avoid Budget Blowouts
- Get a proper feasibility assessment first. Spend the money upfront to understand your existing building's condition, identify hidden issues (rot, asbestos, structural deficiencies), and get a realistic cost range before you commit to a design.
- Design to your budget, not the other way around. We advocate for Early Contractor Involvement: getting a builder involved during the design phase to price things as you go, not after the architect has designed your dream home that costs twice what you can afford.
- Include a contingency. For renovations, budget 10 to 15% contingency for unknowns. For new builds, 5 to 10% is typically sufficient.
- Fix the scope before construction starts. Changes during construction are exponentially more expensive than changes on paper. Be decisive during the design phase.
- Choose a fixed-price contract. A fixed-price contract with a reputable builder transfers cost risk from you to the builder. We offer fixed-price contracts on all EBUILD projects after a thorough scope assessment.

We offer the independent Halo 10-Year Residential Guarantee for structural peace of mind. We also back this with Tony Hodson’s personal workmanship guarantee. We stand by our work long after handover. We do not make excuses. We fix any issues promptly because we value our reputation.
Frequently Asked Questions
All figures on this page are inclusive of GST.
They reflect typical Wellington projects we have completed or quoted in the past 12 months. Your actual cost may fall outside these ranges depending on your specific site conditions, scope, and specification level. We provide accurate pricing during our detailed feasibility assessment.
Yes. Our contracts use a standard progress payment schedule, meaning you pay in stages as work is completed and inspected. This protects both parties and ensures you only pay for completed work.
Low quotes often exclude key items: consenting fees, project management, scaffolding, site access, contingency, or allowances that are set unrealistically low. We include everything in our fixed-price contracts so there are no surprises at handover.
For non-consent-required cosmetic work (painting, landscaping), yes. For anything requiring a Building Consent, the work must be completed by or supervised by a Licensed Building Practitioner. We can advise on which elements you can realistically handle yourself.
