What is a topographical survey?
A topographical survey records the physical features and levels of your land in detail. It shows the rise and fall of the ground, contours, spot heights and the position of existing features across the site. This information becomes the base plan used for architectural design, engineering plans and many consent applications.
If you are planning a new home, extension, garage, shed, subdivision or other site works, a topographical survey is often one of the first surveys needed before design work can begin.
Why accurate site data matters
The layout and slope of your land can influence drainage, earthworks, access, retaining requirements, building design and how a project fits within council rules. Accurate survey information early in the process helps designers work efficiently, reduces the risk of costly changes later and supports smoother approvals.
Detailed surveys using modern technology
At Lamb & Associates, we use GPS and modern survey equipment to capture accurate site measurements and produce detailed computer-generated plans in 3D CAD format. This makes contours, levels and site features easier to understand for everyone involved in the project.
We can provide your architect, engineer or designer with the information they need to start work promptly and help keep your project on track.
What can be included in a topographical survey?
Depending on your site and project requirements, a survey may include:
- Ground levels, contours and spot heights
- Existing buildings and structures
- Floor levels, gutter heights and roof heights
- Walls, fences and retaining structures
- Trees, landscaping and notable features
- Driveways, accessways and paved areas
- Visible service lids, inspection points and surface features where identifiable
- Site dimensions, occupation lines and other relevant site measurements
- Neighbouring buildings or features where relevant to design setbacks and planning
If an addition or extension to an existing building is planned, we can also include the details designers need to help integrate new work with what is already on site.
Suitable for a wide range of projects

Case study: Topographical survey - Whitehills Road, Waitoki
Around 2018, a family member of Chris's purchased a one-hectare vacant lot in Waitoki.
Chris carried out a comprehensive topographical survey of the property, locating existing ground levels, boundary fences, vehicle access points, drainage systems, and the adjacent road edges. Using this information, a topographical plan was created and sent to the building company, which used it to design several house concepts.
The first stage of construction was recently finished in mid-2025, along with significant landscaping work.
A topographical survey provides essential ground level and feature information needed for design and council approval. It helps your architect or engineer create accurate plans from the start.
You receive information on land contours, spot heights, existing structures, boundaries, landscaping features and services entering your property.
Yes, topographical surveys commonly record existing buildings, driveways, fences, retaining walls and visible service features such as manholes, inspection points or utility lids where identifiable on site.
Turnaround times are fast, so you can keep your project moving. Sometimes timeframes depend on the size, terrain and complexity of the site, along with how much detail is required. Smaller residential sites can be completed quickly, while larger or more complex land can take longer. We can advise expected timing when discussing your project.
Yes, your survey is delivered in a computer-generated 3D format (CAD), making it suitable for immediate use in design and planning.
