If you're planning a renovation, building extension, or new development in Sydney, you've likely heard that you need a "detail survey" or "feature survey." But what exactly is a detail survey, and when do you need one? This comprehensive guide explains everything Sydney property owners need to know about detail surveys.
What is a Detail Survey?
A detail survey (also known as a feature survey, topographic survey, or site survey) is a comprehensive survey that captures all the physical features of a property. Unlike a boundary survey which only identifies property lines, a detail survey maps everything on and around your site including:
- Buildings and structures: Floor levels, eaves, gutters, walls, sheds, garages
- Ground levels and contours: The shape of the land, slopes, and elevations
- Vegetation: Trees (with species and canopy spread), hedges, gardens
- Fences and boundaries: Existing fences, retaining walls, boundary locations
- Services: Stormwater pits, sewer inspection openings, water meters, power poles
- Driveways and paving: All hard surfaces and their levels
When Do You Need a Detail Survey in Sydney?
Sydney councils and architects typically require detail surveys for:
- Development Applications (DAs): Most Sydney councils require a current survey for DA submissions
- Architectural Design: Architects need accurate site information to design additions and new buildings
- Renovations and Extensions: Understanding existing levels is crucial for planning work
- New Home Builds: Site levels determine foundation design and drainage
- Swimming Pool Construction: Pool builders need accurate levels and service locations
- Landscaping Projects: Major landscaping requires level information for drainage design

How to Prepare for Your Detail Survey

- Inform neighbours: We may need to briefly access their property to survey near boundaries
- Provide any existing plans: Old surveys or building plans can be helpful

Detail Survey vs Boundary Survey: What's the Difference?
Many people confuse these two survey types:
- A boundary survey identifies and marks your property's legal boundaries
- A detail survey maps all features on your property but may not re-establish boundaries
For most development projects, you need both. We often combine boundary identification with a detail survey for efficiency and cost savings.
