What is a topographical survey?

A topographical survey is a detailed survey that records the physical features, levels, and characteristics of a site. It provides an accurate representation of land and buildings and is commonly used to support planning, design, construction, and land management projects.

Topographical surveys typically record:

• Site boundaries and boundary features

• Existing buildings and structures

• Ground levels and contours

• Trees, vegetation, and natural features

• Roads, paths, drainage, and hardstanding areas

• Walls, fences, access points, and external features

The survey information is used to create accurate plans for professional and legal purposes.

What is a GPS survey?

A GPS survey uses professional Global Positioning System (GPS/GNSS) equipment to capture highly accurate site data and positioning information.

This technology enables surveyors to accurately record locations, boundaries, levels, and site features efficiently and reliably.

Why might I need a topographical survey?

A topographical survey is often required for:

• Planning applications

• Architectural and design work

• Building Regulations and engineering design

• Extensions and new build projects

• Complicated site levelling or drainage design

• Sloping or irregular sites

• Boundary investigations or disputes

• Land development and feasibility studies

Having accurate site information at an early stage can help avoid costly design or construction issues later.

Can a topographical survey help with planning applications?

Yes. A detailed topographical survey often forms the basis of planning drawings, site layouts, and development proposals.

Accurate survey information helps architects and designers prepare compliant, practical, and informed proposals.

Do you survey boundaries?

Yes. We can record visible boundary features including:

• Walls and fences

• Hedges and vegetation boundaries

• Existing boundary structures

• Access routes and neighbouring features

Survey information can be useful in supporting boundary investigations and land-related matters.

Please note that a topographical survey records physical features and does not, on its own, determine legal ownership boundaries.

Can a survey help with boundary disputes?

Yes. Detailed measured and topographical information can assist in understanding physical site features and may support professional advice in relation to boundary matters.

Where required, we can work alongside title plans, historical mapping, legal documentation, and other professional consultants.

What information will I receive?

We provide professionally prepared survey information which may include:

• Topographical survey drawings

• Site level information and contours

• Building and boundary information

• CAD-compatible drawings (where required)

• PDF issue drawings suitable for planning and design

The level of detail can be tailored to suit the intended use of the survey.

Can you survey sloping or difficult sites?

Yes. Topographical surveys are particularly beneficial for:

• Sloping sites

• Irregular land levels

• Sites requiring retaining walls or level changes

• Drainage and external works design

Accurate level information is essential for successful project planning and construction.

Do you provide setting out services?

No. We are unable to offer this service.

Can this service be combined with planning and design work?

Yes. Our topographical and GPS surveys integrate closely with our wider services, including:

• Planning applications

• Architectural design and drawings

• Measured surveys and floor plans

• Building Regulations drawings

• Contract administration and project management

This provides continuity from initial survey through to project completion.
