The cost varies wildly depending on the location, size, and infrastructure requirements of the site.

For a basic two-lot residential subdivision (splitting a backyard off an existing house), you should budget roughly $120,000 to $150,000+.

Here is where that money actually goes:

• Professional Fees: Surveyors, planners, civil engineers, and solicitors.
• Council Fees: Processing resource consents and engineering approvals.
• Development Contributions (DCs): A mandatory fee charged by Whanganui District Council to fund the extra strain your new section puts on community infrastructure (roads, parks, water). This alone can range from $12,000 to $40,000+ per new lot.
• Civil Works & Infrastructure: Laying new pipes for wastewater and stormwater, installing power/telecom connections, and building a legal vehicle crossing (driveway).
• At Venture Build we work out the costs for you, along with building options that actually stack up.
