Six-Lot Residential Development and Subdivision in Henderson
Project Lead: Chris Walsh, Director (Planning)
Tripp Andrews was engaged to provide surveying, planning and engineering services for a six-lot residential development in Henderson.
The project required an integrated design and consenting approach to maximise the development yield while meeting the client’s objectives and achieving an outcome Auckland Council could support.
The Challenge
Residential development design often involves tension between maximising a site’s potential, controlling construction costs and satisfying council requirements.
Key challenges included:
- Developing a six-lot design that maximised yield within the client’s objectives
- Coordinating the architectural, engineering and subdivision requirements
- Navigating the resource consent and Engineering Plan Approval processes
- Identifying opportunities to improve project feasibility after resource consent had been granted
- Responding to unsubstantiated concerns raised by Vector, which owns a neighbouring property
Our Approach
Tripp Andrews worked closely with the architect throughout the design and approval process, providing the surveying, planning and engineering expertise needed to keep the development moving.
Our work included:
- Completing the topographic survey
- Preparing the scheme plan and subdivision design
- Providing engineering design for resource consent
- Navigating the resource consent process through to approval
- Preparing detailed engineering design for Engineering Plan Approval
- Addressing Vector’s concerns about the potential effects on its neighbouring land
During the Engineering Plan Approval stage, we revisited the conceptual stormwater design approved at resource consent. By developing a more efficient solution, we were able to significantly reduce the extent of the previously approved public stormwater extension.
Tripp Andrews will also provide engineering supervision and certification, construction surveying and land transfer surveying as the project progresses.
Solution Delivered
- Resource consent approval for a six-lot residential development
- A coordinated design that maximised yield while meeting the client’s objectives
- Engineering Plan Approval successfully navigated
- A significantly reduced public stormwater extension
- Unsubstantiated concerns from the neighbouring landowner successfully addressed
- An integrated pathway from initial surveying through to construction and land transfer
Client Outcome
- The client gained certainty to proceed with the six-lot development
- The revised stormwater design delivered significant potential construction cost savings
- Project feasibility and costings improved after resource consent approval
- The site’s development potential was maximised within council requirements
- Regulatory, engineering and neighbouring-property concerns were resolved without unnecessarily compromising the development
“Tripp Andrews is the very high standard for property development planning. Having partnered with Chris across multiple projects since 2020, his consistency is elite.
In this industry, foresight is the ultimate hedge against project risk. Chris identifies critical regulatory and logistical hurdles long before they materialize, saving us significant capital and time. His strategic input has repeatedly salvaged complex situations that were invisible to us at the outset.
Chris’s exceptional knowledge, strong eye for details and keeping tight control on our cost delivered high ROI. Chris played a key role delivering the final results of our multiple projects.
Chris and Tripp Andrews remain our exclusive choice for all future developments.”

Why This Matters
A design approved at resource consent does not always represent the most cost-effective construction solution. Continuing to review and refine the engineering design during later approval stages can uncover valuable opportunities to reduce infrastructure costs.
By significantly reducing the required public stormwater extension, Tripp Andrews improved the project’s feasibility after resource consent had already been granted. This demonstrates the value of having an experienced multidisciplinary team continue looking for better solutions throughout the approval process—not simply accepting an earlier design when it can be improved.
