A measured building survey accurately records an existing building’s dimensions, layout and structural features to produce floor plans, elevations, sections, 2D CAD drawings, Revit BIM models and registered point cloud data for planning, design, refurbishment and construction projects.
At XP Surveys, our measured building surveys are delivered to ±2mm accuracy using industry-leading Trimble X7 and Leica RTC360 3D laser scanners. Every survey produces verified, coordinated deliverables ready for immediate use by architects, developers, engineers, commercial property owners and homeowners across the UK. For projects in the capital, see our dedicated Measured Building Survey London service covering all 32 boroughs.
Using High-Definition Surveying (HDS), our scanners capture millions of measurement points every second, accurately recording a building’s geometry, structure and spatial layout. The resulting registered point cloud provides a reliable existing-condition record that reduces project risk, minimises unnecessary return site visits and supports confident planning, design development and technical coordination throughout the project lifecycle.
From residential extensions, loft conversions and listed buildings to commercial developments, industrial facilities and complex multi-storey projects, each measured survey delivers coordinated CAD and BIM outputs tailored to the required level of detail.
Our measured surveys support planning applications, refurbishment schemes, listed building consent, commercial lease analysis (GIA/NIA), asset management and detailed design coordination.
Reliable, highly accurate survey data forms the foundation of every successful design project. Whether working on a private home, commercial property, constrained urban site, complex multi-storey development or sensitive heritage building, XP Surveys delivers survey-grade information that helps architects, engineers, contractors and project teams work more accurately, efficiently and with fewer unnecessary return visits.

See how 3D laser scanning captures a building and transforms it into survey-grade CAD and BIM deliverables.
Our surveyors use Leica RTC360 and Trimble X7 3D laser scanners to capture millions of highly accurate measurement points every second, creating a precise digital record of existing buildings. This survey data supports planning applications, refurbishment, conservation projects, design coordination, asset management and construction across residential, commercial and heritage properties.
Every project begins with High-Definition Surveying (HDS) to capture a building’s geometry, structural features and spatial layout. The registered point cloud is processed into coordinated deliverables, including floor plans, elevations, sections, 2D CAD drawings and Revit BIM models, providing a complete and accurate digital record of the property.
All survey information is referenced to a common control framework, ensuring consistency across every drawing and model. Architects, engineers and contractors can extract additional dimensions directly from the registered point cloud without repeat site visits, improving technical coordination, reducing project risk and supporting efficient design development throughout the project lifecycle.
The as-built documentation can be tailored to suit different project requirements, depending on the level of detail needed and how the survey data will be used. Selecting the right survey type ensures architects, developers and contractors receive accurate existing-condition information that supports confident planning, design and construction decisions.
From basic floor plans through to detailed laser scanning and BIM-ready outputs, our building measured surveys provide flexible solutions for residential and commercial projects of all sizes.
| Measurement Types | Description | Use Case |
|---|---|---|
| Basic Floor Plan | Essential internal layouts showing wall positions, openings, room dimensions and key structural elements. | Ideal for renovations, layouts and early design stages. |
| Elevational | Detailed measurements of building façades, including windows, doors, rooflines and architectural features. | Commonly used for planning applications and façade works. |
| Internal and External Elevation | Comprehensive documentation of both exterior surfaces and internal structural features, such as beams and columns. | Suitable for refurbishments and heritage projects. |
| Detailed Data Survey | Enhanced survey detail including fixtures, fittings and internal building elements where required. | Best for complex refurbishments or technical design stages. |
| 3D Laser Scanning | High-density point cloud capture used to create precise 3D models and BIM deliverables. | Ideal for complex structures and high-accuracy projects. |
| External Site & Context Surveys | Mapping of surrounding land and external features to complement building survey data. | Used when extensions or landscape changes are involved. |
As-built drawings provide architects, engineers and planners with the information required to move projects forward with confidence. The level of detail is tailored to suit each project, ensuring coordinated survey information throughout the design and construction process.
Fast laser scan surveys provide architects with dependable existing-building information from the outset. Using advanced laser scanning and BIM-ready workflows, we capture high-density point cloud information that integrates seamlessly into Revit and CAD environments – helping design teams save time, reduce risk and maintain consistency throughout the project lifecycle.
Architects, developers and contractors rely on measured building survey information to support confident design and construction decisions. Incomplete or outdated existing-condition drawings can lead to delays, coordination issues and unnecessary project costs.
Every survey is delivered in the formats your team needs – including 2D CAD drawings in AutoCAD (.dwg), 3D Revit BIM models, ArchiCAD-compatible files and raw point cloud data (.rcp/.e57). Outputs integrate directly into existing architectural and construction workflows without additional processing.
This allows architects, engineers and contractors to work from coordinated building information throughout design development, technical coordination and project delivery.
CAD-ready outputs can be delivered in as little as 7 days. We use industry-leading equipment, including the Trimble X7 and Leica RTC360 to capture detailed building information to ±2mm accuracy, with clear fixed pricing and no hidden fees.

A measured building survey is usually required when accurate existing-building drawings are needed for planning, refurbishment, extensions, structural alterations or ongoing building management.
CAD/BIM deliverables are required at various stages of property development and management to ensure accurate planning and execution. The specific instances when an existing measured survey is required to improve accuracy include:
As-built precise building measurements are vital throughout the lifecycle of a property, from initial planning to ongoing maintenance, providing accurate data that supports informed decision-making and project success.
The cost depends on property size, complexity, access, level of detail and required outputs such as CAD drawings or BIM models.
Measured survey costs vary significantly depending on project scope – a standard 2–3 bed house costs far less than a multi-storey commercial building.
At XP Surveys, pricing is transparent and straightforward, with no hidden fees or vague estimates. Final costs are based on the scale of the property, accessibility, required level of detail and the type of deliverables needed for your project.
Here’s what you can expect:
| Property Type | Typical Cost (From) |

A measured survey is the professional process of recording the dimensions, layout and structural features of an existing building or site. The result is a set of verified drawings – typically floor plans, elevations and sections – used to support planning applications, refurbishments, extensions and construction projects.
Measured building surveys range from basic floor plans to advanced 3D laser scanning and BIM-ready outputs, depending on project requirements. They provide architects, designers and construction teams with reliable existing-condition information before design work begins.
3D laser scanning allows surveyors to capture complex buildings and structural details quickly and efficiently. The process reduces the need for repeat site visits while supporting accurate floor plans, elevations, sections and technical documentation.
Laser scanning also creates detailed point cloud information that can support CAD drawings, BIM workflows and refurbishment projects.
On-site survey times depend on the size, complexity and level of detail required. Smaller residential properties may take a few hours on-site, while larger buildings or surveys including elevations, sections and laser scanning can take several days. Finished CAD deliverables are then issued within our standard turnaround time.
A point cloud is a digital collection of measured points captured using 3D laser scanning technology, creating a detailed representation of a building or site.
Point cloud information can be used to support CAD drawings, BIM modelling and technical coordination workflows. Explore our point cloud survey services.
Many planning applications require accurate existing-condition drawings before proposals can be assessed. A measured building survey provides the floor plans, elevations and sections that architects use to prepare planning drawings, giving the planning authority a reliable record of the current building. Exact requirements vary by project type and by your local planning authority.
