We will survey all accessible floors in the property and provide plans showing all visible walls, windows, doors, spot height levels, ceiling/roof heights, window sill/head heights.
A topographical survey (commonly known in the property development world as a topo survey) is a comprehensive and accurate assessment of a site or section of land, which takes into account all potential considerations that relate to a specific planned future development.
Topography is the study of the natural and artificial features of a landscape. Natural topographical features include terrain – the inclines, mounds and hollows of the land – as well as natural growth such as isolated trees and areas of woodland or scrub. They will also include bodies of water, including rivers and streams, ponds and lakes.
Artificial topographical features are man-made: roads and paths, boundaries, buildings and other structures, street signs, lighting and furniture, and visible services (manhole covers, power lines, telephone cabinets).
A topographical survey is an accurate and comprehensive assessment of a tract of land, used to create a three-dimensional map that shows the contours of the land and the position and height of its natural and artificial features. This includes details such as the position of road markings, the types of path and road surfaces and the heights of tree canopies, eaves heights and overhead cables.
Topographical surveys are 3-dimensional (height being an important measurement, not just gridline position), and will often be related to GPS positioning and/or Ordinance Survey references. CAD software is the widely accepted industry standard that allows accurate 3D mapping to be saved digitally, which can then be outputted in a variety of 3D and 2D views as required.
An extract from a topographical survey is shown on our topographic services page, showing the level of detail and accuracy of measurements.
When a topographical survey is requested, there is always a potential development being considered, e.g. a residential or commercial property development.
The purpose of the topo survey is to assess all limitations and considerations relating to the site in question, to allow the architect or property developer to assess the feasibility of the proposed development, as well as decide what can and can’t be done, bearing in mind the findings of the topo survey.
If your project is relatively small – for example, a house extension – it’s unlikely a full topographical survey will be needed. Smaller projects that might require a topographical survey include moving or establishing boundaries.
For larger projects, however, planning authorities will require a topological survey as they will refer to it for considerations such as understanding the visual and environmental impact of the development and how it will connect with existing infrastructure and services.
Whilst topo surveys are often requested by architecture firms and property developers, the range of people and organisations that may want a topographical survey conducted is wide.
Homeowners and commercial property owners who want to assess the value of their property or section of land for future alternative development may well need a topo survey to help them evaluate this.
And construction companies who have an in-house design team are another common client of a topographical survey provider such as XP Surveys.
In layman's terms, a topo survey is an accurate, detailed, and thorough site survey or land survey, more concerned with the potential of the site (i.e. a plot of land defined by a specific boundary), than it is concerned about any existing buildings on that site.
A measured survey, by contrast, is focused on the existing building(s), and so is more appropriate when renovating or extending an existing property, than the overall potential of the plot that the property is located on. Many construction works such as large extensions or new builds benefit from having both a topographic and a measured building survey done, so the architect and planners can determine how the alterations sit within the site. The planning department will likely require a topo survey for large developments, so factors such as the views and sight lines can be assessed.
While our measured survey pricing guide gives helpful and transparent information on the typical costs of topo surveys, we do regard every survey request as a bespoke requirement. Use our Quote Request tool or contact us for a fast response.
If a site warrants a particularly detailed examination of various aspects, maybe due to its conservation area status or historic significance, or even due to the ambitious nature of the planned development, then a tailored survey package will be quoted on each occasion, suited to your requirements.
At the moment, we cover Greater London and the Home Counties.
London has many additional considerations not found in less densely populated areas of the UK, so hiring a local specialist if your project is within London is a smart choice.
Each borough of London has its own set of restrictions and local history, so again, a London-based topo surveys firm is a smart choice for any construction projects in the London area.
Using our specialist equipment, our CAD surveys can output in AutoCAD (.DWG), Revit (.RVT), ArchiCAD (.XYZ or .e57), or PDF formats.
This gives you contours, GPS positioning, levels and 2D sections in any direction required.
We were thrilled to be invited to collaborate with YADA at the London Build Expo in 2023 by sponsoring the launch of their first ‘Speed Mentoring’ event. The Young Architects & Developers Alliance (YADA) was founded in 2016 by Martyn Evans (Property Developer) and Jane Duncan (former President of RIBA) and was formed as a […]News
As every ArchiCAD user knows, it’s a great program for 2D and 3D architects’ work as it brings together technical and aesthetics into one model and uses the ever-more popular BIM (Building Information Modelling) framework. Unlike most other architectural design software, the ArchiCAD program was built for architecture from the start, rather than being an […]Measured Survey Topo Survey

The latest unmanned survey techniques and advancing technology, platforms, optics, ease of control, and fast download speeds mean that a drone survey cost is now a great investment. Our customers for drone surveys include homeowners, builders, landlords, and civil engineering firms that want a fast and accurate drone roof survey and inspection to show due […]Topo Survey
We use Area data from your property's EPC certificate and the UK Ordnance Survey database to calculate your quote estimate. If there is not enough data in the UK database we cannot provide an instant quote, but one of our team will be able to provide a formal written quote by email within 48 working hours. If the database holds incorrect data on your property you will still be provided an estimate, but our fee is subject to change to suit the actual size of your property
