Benefits of 3D Getting A Measured Survey

Accuracy & Precision

Measured building surveys provide highly detailed and accurate data about the existing conditions of a property. This precision is crucial for architectural planning, ensuring that designs are based on exact measurements and reducing the risk of errors during construction.

Efficiency and Speed

Conducting a measured building survey before construction rapidly captures comprehensive data, saving significant time compared to traditional methods. This efficiency helps streamline the planning process, minimises delays, and facilitates faster decision-making.


By providing accurate and detailed information upfront, measured building surveys reduce the likelihood of costly mistakes and rework during construction. This proactive approach leads to substantial cost savings and more efficient resource allocation throughout the project.

Our Measured Building Survey Process

Initial Consultation / Quote

In response to your enquiry, we need to discuss your specific requirements, including the areas to survey and the necessary outputs (e.g., BIM model, plans, elevations). After this discussion, we will provide a fixed price quotation for the work.

On-Site Survey Work

Our surveyors will visit your site to conduct a comprehensive 3D laser scan using the latest Faro technology. We will meticulously navigate the building to capture all the details discussed during the quotation stage.

Data Processing

Once the on-site work is completed, we return to the office to process and register the data. Our goal is to produce a fully registered point cloud file.


Once the point cloud file is complete, we can begin producing the elements you require, such as a BIM model, 2D drawings and plans, mesh models, and more.

What Our Measured Surveys Provide

Following your measured building survey, we can provide a range of different 2D, 3D and BIM outputs including:

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 Plan

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.

Site Plan

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.

Loft Plan

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.

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.

Point Cloud File

A point cloud is a collection of data points in space produced by 3D scanning technologies to create detailed models of physical environments; for a more detailed description, visit this link.

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.

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.

Our survey service is designed to capture a diverse range of elements, depending on your specific requirements.

For more complex assignments, we extend our survey to include additional elements such as radiators, electrical outlets, lighting positions, and more.

If you require further guidance on what to include in your survey, RICS offers a comprehensive document titled ‘Measured Surveys of Land, Buildings and Utilities

The cost of a measured building survey in London can vary depending on several factors, including the property’s size, its location within the city, and the level of detail needed. For a typical 3-bedroom house, you can expect costs to range from £1000 to £2000, based on the specific requirements of the project. For a more in-depth look at pricing and factors that influence it, please check out our detailed article on measured survey costs.

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.

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.
