A measured building survey company specialises in the accurate recording of building dimensions, layouts, and architectural features using precision surveying methods and digital technology.

Since reliable base drawings are critical to planning applications, refurbishments, and design decisions, a professional measured survey delivers floor plans, elevations, sections, and 3D models that reflect the exact conditions of your property.

Surveyors use tools such as laser scanners, total stations, and CAD software to produce drawings and models for architects, developers, consultants, and property owners.

Whether you need a building elevation survey, a building plan survey, or a full site plan survey, we provide accurate, customisable outputs for every type of project.

What Does a Measured Building Survey Company Do?

A measured building survey company captures precise, scaled information about a building’s internal and external structure.

This includes measuring walls, door and window positions, ceiling heights, staircases, rooflines, and structural details.

As many properties lack reliable documentation—or have been modified over time—measured surveys ensure project teams are working with verified and up-to-date data.

Why Are Measured Surveys Important?

A measured survey is essential because even small discrepancies in existing plans can lead to major issues in design, construction, or planning submissions.

By delivering current, high-accuracy drawings, a measured survey prevents costly redesigns, site errors, or regulatory rejections.

This is particularly important in older buildings, change-of-use projects, or developments involving structural alterations.

What Types of Surveys Are Offered?

As a professional measured building survey company, we offer a range of services tailored to project needs.

A typical building plan survey includes internal floor layouts with doors, windows, walls, sanitaryware, and access points.

A building elevation survey provides external façades drawn to scale, showing window positions, materials, rooflines, and architectural detailing.

A site survey records boundary lines, access routes, and surrounding topography, while a site plan survey combines external and internal building layouts with spatial context.

These surveys can be delivered in 2D CAD or as fully coordinated 3D models for BIM integration.

What Is the Level of Accuracy?

Measured surveys are typically delivered with a tolerance of ±5 mm, making them suitable for architectural, structural, and planning applications.

Surveyors use laser scanning and total stations to capture thousands of data points, which are then processed into scaled drawings through CAD software.

As precision is vital to structural safety and compliance, all data is verified through internal quality assurance procedures.

How Much Does a Measured Survey Cost?

The cost of a measured building survey is from £600 to £5,000+.

The cost depends on the property size, number of floors, complexity, and required detail.

A basic building plan survey for a small residential property may cost between £600 and £900, while a full building elevation survey with internal sections for a commercial site may cost £2,500 to £5,000 or more.

We provide custom quotations following a site brief, access review, and review of existing plans or photos.

When Are These Site Surveys Needed?

A measured survey is required at various stages of property development and management.

Architects and planners need up-to-date base drawings to prepare applications and designs. Engineers use the data to calculate structural loads. Contractors rely on accurate plans to avoid clashes or costly rework.

A site survey or site plan survey is also essential for extensions, new builds, and boundary confirmation.

What Are the Benefits of Working with a Measured Building Survey Company?

Working with a professional survey company ensures your project starts with clarity, reduces risk, and supports compliance.

The key benefits include:

• Accurate base drawings – Supports all planning, design, and construction work
• Eliminates outdated information – Removes reliance on assumptions or historic floor plans
• Supports planning permission – Produces scalable drawings that meet local authority standards
• Flexible detail levels – Choose from basic layouts to full internal and external architectural detail
• 3D and BIM integration – All surveys compatible with Revit, AutoCAD, and IFC formats
• Time and cost savings – Reduces design errors, delays, and rework during construction
• Suitable for all property types – Residential, commercial, heritage, education, and public buildings

Since measured building data influences every downstream decision, a professional survey is a key investment in project success.

Do You Work with Occupied or Live Buildings?

We frequently carry out measured surveys in occupied buildings across, including homes, offices, schools, hospitals, and public spaces.

Our surveyors work with discretion and efficiency, minimising disruption to occupants while capturing the required data.

Where necessary, we can also carry out surveys outside working hours or in planned phases to suit access and operational requirements.

What Is the Typical Turnaround Time?

Most standard residential properties are surveyed in 1 day, with drawings delivered in 5 to 7 working days.

Larger or multi-storey commercial properties may require 2–3 days on site and a 10-day turnaround for CAD drawings and BIM files.

Turnaround time for a measured survey varies by scope.

Urgent building surveys can be fast-tracked where scheduling allows.

What File Formats Are Delivered?

As a standard, we provide all measured surveys outputs in AutoCAD DWG, PDF, and optionally in Revit (RVT) or IFC formats for BIM workflows.

We also supply point clouds, elevation files, room schedules, and area breakdowns where required.

All drawings are quality checked and formatted to suit your project team’s software and documentation standards.

Can You Combine a Measured Survey With a Site Survey?

We can carry out a measured survey alongside a site survey as part of an integrated service.

Because most design and planning projects require both building and surrounding land data, combining surveys provides a full picture of the site’s internal and external conditions.

This is particularly beneficial for extensions, access plans, drainage strategies, and planning applications, where both building and terrain must be represented accurately.

What Is the Difference Between a Measured Survey and a Site Plan Survey?

A measured survey focuses on the internal and external dimensions of a structure, including floor layouts, walls, windows, and elevations.

A site plan survey includes the footprint of the building in its geographical context, showing boundary lines, access points, landscaping, and any external features around the property.

Because many planning submissions require both types of information, clients often commission both surveys simultaneously for full documentation.

How Is a Building Plan Survey Used in Planning?

A building plan survey is used as the base drawing for planning applications, renovation designs, and change-of-use proposals.

Because local authorities require accurate and scalable plans to assess development proposals, the building plan becomes an essential reference for layout changes, extensions, and structural alterations.

It also supports consultants such as structural engineers and building control specialists in assessing compliance.

Is a Building Elevation Survey Required for Listed Properties?

A building elevation survey is highly recommended, and often required, when working with listed buildings or properties in conservation areas.

Since elevation drawings show the architectural appearance, materials, and façade detail, they help support heritage statements and applications for listed building consent.

We can produce elevations of all visible façades, including rear extensions, side walls, and adjoining properties where relevant.

How Detailed Can a Measured Survey Be?

The level of detail in a measured survey can be customised to match your project requirements, from basic structural layouts to high-detail internal features.

For example, a standard survey might include only walls, doors, and windows, while a detailed survey may add floor finishes, radiators, ceiling profiles, kitchen units, and service points.

Since survey data is often used by multiple disciplines, we can also add layers and annotations to clarify specific design elements.

Can You Carry Out a Measured Survey for a Single Flat?

We regularly provide measured surveys for individual flats, maisonettes, or leased units within larger buildings.

Since property owners, leaseholders, and landlords often need accurate documentation for refurbishment or sale, these focused surveys are tailored to single dwellings while respecting shared access and communal areas.

We also provide lease plans, HMO compliance layouts, and area breakdowns where required.

Do You Offer Revisions if My Design Changes?

We offer drawing updates and revisions if your design requirements evolve after the original measured survey is completed.

Since we retain the original point cloud or CAD files, we can revise layouts, add detail, or adjust annotations without needing a second site visit—unless the building has changed physically.

This flexibility is ideal for phased developments or projects with multiple stakeholders.

Is a Site Plan Survey Suitable for Boundary Disputes?

A site plan survey can provide supporting evidence for boundary positioning, especially where the physical layout differs from title plan assumptions.

Although not a legal determination, a professionally prepared site plan with Ordnance Survey overlay and scale annotations can help clarify dimensions for solicitors, land agents, or mediators.

For formal boundary disputes, we may recommend a measured boundary survey in addition to the site plan.

Do You Provide Measured Surveys for Fire Risk Assessments?

We provide measured surveys that support fire strategy development and fire risk assessments, particularly in commercial and public sector buildings.

Since accurate layouts showing fire doors, escape routes, staircases, and compartmentation are required for compliance, our surveys can be tailored to show these features clearly.

We also work with fire consultants to produce CAD-based evacuation plans or fire zoning diagrams using the surveyed data.

Can You Survey Properties Without Original Drawings?

A measured building survey is often commissioned when no reliable existing drawings are available or when historical plans are inaccurate.

Because buildings may have undergone undocumented alterations over time, our team surveys from scratch to produce a fully verified set of floor plans, elevations, and sections.

This is common for older properties, complex conversions, or acquisitions where prior documentation is unavailable.
