Our Measured Survey Service In Detail

On-Site Survey

Our seasoned site survey team will visit your property to conduct a comprehensive 3D scan, capturing all the necessary measurements to create your precise drawings.

You have the option to provide us with your exact specifications, or you can rely on our expertise, honed from completing hundreds of measured survey projects over the years, to recommend the best approach for you.

CAD Drawings & PDF's

We utilise Autodesk’s industry-leading AutoCAD software to craft your CAD floor plans, sections, elevations and more.

Over the years, we’ve fine-tuned our drawing package to maximise efficiency, enabling our clients to seamlessly integrate, manipulate, and expedite their design projects.

Key Features Of Our Drawings:

  • Through the use of layers, we organise the drawing meticulously, incorporating helpful colour coding, line types, and line weights for ease of use.
  • We avoid cluttering the drawings with extraneous information, making them more straightforward and easier to comprehend.
  • Upon request, we can align the drawings to Ordnance Survey grids, simplifying the integration of additional mapping data.
  • Each drawing undergoes rigorous quality checks before dispatch to eliminate any elements that could lead to confusion.
  • We provide scaled PDF copies, facilitating printing and markup for those who may not have access to AutoCAD.

For more information on CAD standards, you may refer to CAD Standards.

Point Cloud File

Upon completion of your measured survey or 3D laser scan, we offer you a link along with complimentary software to access the point cloud file of your building.

A point cloud enables you to navigate through your building in a virtual environment. You can take measurements, add markups, and experience your building as a 3D visualisation right on your computer!

For more information on how to utilise point cloud data, you may refer to Autodesk’s Point Cloud Software.

On-Site Photographs

During our visit to your property, we capture a series of photographs to assist us in the CAD drawing process. These images not only facilitate our work but can also be invaluable to you.

We offer to share this photo folder with you, which could serve multiple purposes. It can be a useful resource for future reference or even act as a compelling before-and-after record of your property.

For tips on how to effectively use photographs in your design projects, you may refer to this ArchDaily article.

We can tailor our services to provide various types of CAD drawings to meet the specific needs of your project.

Floor Plans

A floor plan is a two-dimensional layout of a room or building, showing the relationships between rooms, spaces, and other physical features at one level of the structure.

It typically includes dimensions and labels for doors, windows, walls, and fixed objects, as well as furniture and appliances.


An elevation drawing shows a 2D representation of a building viewed from the front, rear, or side, with details on its vertical features. These drawings are often used with floor plans and sections to show a complete representation of the building.


A section drawing is a drawing that shows a slice through an object, illustrating its internal features and arrangement. It is used in engineering, architecture, and construction.

Roof Plans

A roof plan is a specialised architectural drawing that provides an overhead view of a building’s roof structure. It typically includes details such as the roof’s pitch, material, and features like chimneys and vents, as well as drainage systems.

Loft Plans

A loft plan is a detailed architectural drawing that focuses on the layout and features of a loft space within a building. It often includes dimensions, structural elements, and any specific design features like skylights or storage areas. Loft plans are particularly useful for conversions or renovations.

Site Plans

A site plan provides an aerial view of the entire property, including the building, landscaping, and any external features like driveways or garden paths. It’s essential for understanding the layout of the property, and is often required for planning permission.

Street Scene Elevations

These drawings provide a view of how the building will look from the street level, often in the context of neighbouring buildings. They are particularly important for understanding the visual impact of a new building or renovation on its surrounding environment.

Internal Wall Elevations

These are vertical drawings that show the details of internal walls within a building. They can include the placement of windows, doors, built-in features, and sometimes even furniture. These drawings are crucial for interior design and renovation projects.

Frequently Asked Questions

A measured building survey is a thorough and precise examination of a building’s size, features, and overall condition. This process typically requires a surveyor to visit the building and use specialized tools like lasers or total stations to gather detailed information about the building’s layout, features, and state.

Based on the data collected, the surveyor will create detailed plans and drawings, including floor plans, elevations, sections, and other views of the building.

Measured building surveys are conducted for a variety of reasons, including designing renovations or extensions, obtaining building regulations / planning applications, or simply gaining a better understanding of the building’s layout and condition.

For a more comprehensive guide to measured building surveys, please refer to our detailed article here.

The cost of a measured building survey depends on a number of factors such as the size of the property, the location and the level of detail required. A typical cost for the average architect’s requirements on a 3-bedroom house will be between £1000 and £2000.

We have written an article on how much you can expect to pay for a measured survey.

A measured building survey is a critical step for architects, engineers, and construction professionals to begin their projects accurately. By precisely surveying the required area and producing accurate CAD drawings, the survey forms the basis of the design proposals. Without a quality survey, design and build issues may arise.

This type of survey is detailed and involves taking precise measurements of a building’s dimensions, including the size, location, and shape of all features and components. A measured dimensional survey offers several benefits, such as providing accurate and detailed plans of a building’s layout and features for purposes like designing renovations or extensions, preparing building regulations applications, or simply understanding the layout of a building.

Moreover, a measured dimensional survey can be instrumental in planning construction projects, meeting legal requirements or lender requirements for mortgage applications, or determining a property’s value by providing a detailed and accurate assessment of its features and dimensions.

In summary, a measured dimensional survey is an indispensable tool for anyone seeking to understand a building’s dimensions and layout, especially for those planning renovations, extensions, or other building work.

At THS Concepts, we use Autodesk AutoCAD to produce all our drawings in DWG format. Our organised drawing layout speeds up your design work, while our default production of PDF drawings allows for easy paper mark-ups. We specialize in producing high-quality plans, elevations, sections, roof plans, and more, so you can rely on us for all your design needs.

To measure a building, we use a range of high-tech equipment. The primary piece of equipment is a 3D laser scanning device which scans over 100,000 points per second. The 3D scanner surveys an extremely detailed picture of a building, allowing us to present the drawings in a very accurate, precise and detailed manner.

We use a range of other equipment depending on the complexity of the job. From the more complex total stations and GPS equipment to laser measures and measuring tapes.

When in the office we use a variety of software packages to process the information. For our point cloud data we use a program called Faro Scene which helps clean up and register point cloud files together. We use Autodesk AutoCAD for our CAD work.

This obviously depends on the size and the scope of the project. Typically, we will be able to get to your site within 10 days and drawings are usually issued within 7 days of the final day on site.

Absolutely, we can liaise with your design team directly or even discuss what you may require for your project. We have undertaken 100’s of measured survey projects so know what is usually required depending on what you are looking to build.

Yes. The land around your building is often very important when planning a project. We can undertake topographical land surveys to pick up all the detail you require.

Our measured building surveyors provide you with accurate, easy to manipulate measured building survey information to help you design your projects more effectively. You can rely on the information we provide, which is undertaken to RICS (Royal Institute Of Chartered Surveyors) standards.

Our clients receive great service from us, which is reflected in our 5 star reviews on Google and Trustpilot. We ensure you are happy before, during and well after the project has ended.

As a professional surveying company, we carry all the relevant insurance to give our clients confidence in what we produce. We offer a money-back guarantee on all our work and have £5 million in both professional and public liability insurance.
