Recommended 1400 x 600pxWhat is a Measured Building Survey?
A measured building survey records the physical layout and geometry of an existing building. It captures accurate dimensions, structural features and key elements to create a reliable base for design, planning and construction work.
This information is typically used by architects, designers, engineers and contractors at early project stages to ensure any proposed works are based on verified, accurate existing conditions. Without an accurate measured survey, design decisions are made on assumptions — a measured building survey removes that risk entirely.
What We Can Provide
Our measured building surveys are tailored to suit the specific requirements of each project. Depending on your needs, we can provide:
- Existing floor plans showing room layouts, wall thicknesses and key features
- Elevations showing external building features, openings and heights
- Sections to illustrate internal layouts and level changes
- Roof plans where required for planning or design use
- Floor-to-ceiling heights and level information throughout
- Clearly identified doors, windows and openings with sizes
- Key structural elements captured as part of the survey
- Reflected ceiling plans where required
Deliverables are agreed at the outset to ensure survey information is appropriate for its intended use.

What is a Measured Building Survey?
A measured building survey records the physical layout and geometry of an existing building in precise detail. Using calibrated measuring equipment and professional surveying techniques, we capture accurate dimensions, structural features and all key building elements to create a verified, reliable base for any design, planning or construction project.
The survey produces a complete set of drawings representing the building as it exists — not as it was originally designed or built. Over time, buildings change: walls are moved, openings are altered, additions are made. A measured building survey captures the building as it actually stands today, giving your design team verified information to work from rather than guesswork.
This is the standard starting point for virtually any project involving an existing building — from a simple extension to a major refurbishment or change of use.

Site plan — building in context with boundaries and levels
How We Capture Your Building
Our measured building surveys use a combination of modern measurement tools and professional CAD production to deliver drawings that meet the standards expected by architects, planning authorities and construction teams.
Measurement methodology
We use a combination of hand measurement, digital measuring devices and — where required — 3D laser scanning with the Leica BLK360 to capture building dimensions accurately. The method is selected based on building complexity, access and required level of detail.
CAD production
All drawings are produced in professional CAD software (AutoCAD / BricsCAD) with clean layer structure, correct line weights and clear annotation. Files are delivered in DWG and PDF format and are ready to use in your design workflow without rework.
Accuracy and checking
Survey data is cross-checked before drawings are produced. Dimensions are verified against each other at multiple points to identify and resolve any inconsistencies — a quality assurance step that protects the integrity of every drawing we issue.
Scales and standards
Drawings are typically produced at 1:50 for floor plans and sections, and 1:100 for elevations. We follow recognised surveying and drawing standards and can adapt to specific requirements from your project team or planning authority.
Coordinate control
Where required, surveys can be tied to Ordnance Survey National Grid coordinates and OS datum, ensuring your building drawings align with site surveys and wider development data.
Delivery formats
All drawings are issued as both DWG (for use in CAD and design software) and PDF (for printing, sharing and planning submissions). Additional formats such as IFC or DXF can be provided on request.
The Value of Getting It Right
Eliminate uncertainty
Design decisions made from accurate survey data are reliable. Without it, even small errors in assumed dimensions can cause significant and costly problems during construction.
Reduce design risk
Accurate existing condition drawings allow your design team to identify constraints, clashes and opportunities early — before they become expensive problems on site.
Support planning
Planning applications typically require accurate existing and proposed drawings. A professional measured survey provides the compliant base drawings needed for a successful submission.
Speed up design
A complete set of survey drawings eliminates the need for your design team to measure the building themselves, saving time and allowing design work to begin immediately.
Protect your budget
Unforeseen conditions during construction are a leading cause of budget overruns. Accurate survey data reduces the risk of costly surprises when work begins on site.
Create a permanent record
Survey drawings remain a valuable asset long after the project is complete — for facilities management, future works, insurance and asset records.
What Goes Wrong Without a Proper Survey
Skipping or cutting corners on a measured survey is a false economy. Here are the most common problems that arise when projects start without accurate existing condition data.
Working from outdated drawings
Relying on original architectural drawings or planning documents is risky — buildings rarely match their original drawings exactly. Alterations, repairs and natural movement all change dimensions over time.
Self-measuring without the right tools
Tape measure surveys carried out by non-surveyors routinely contain errors. Even small inaccuracies compound across a building and can result in design elements that simply do not fit on site.
Assuming dimensions from photos
Photographs cannot provide accurate dimensions. Perspective distortion and lens effects make photographic measurement unreliable and unsuitable as a basis for design.
Discovering problems during construction
If existing conditions are not properly understood before design, problems frequently emerge during construction — when they are most expensive and disruptive to resolve.
Planning application delays
Inaccurate or incomplete existing drawings are a common cause of planning application rejection or the requirement for costly amendments before re-submission.
What Affects the Cost
The cost of a measured building survey depends on a number of factors specific to your building and project. We provide clear, competitive quotes tailored to each job — there are no hidden fees.
Building size
Larger buildings with more rooms, floors and features take longer to survey and produce more drawings — the most significant factor in survey cost.
Number of drawing types
A floor-plan-only commission costs less than a full package including elevations, sections, roof plan and levels. We agree the scope upfront so you only pay for what you need.
Building complexity
Irregular geometry, multiple split levels, complex roofs and restricted access all add time. Historic or listed buildings often require more care and additional methodology.
Use of laser scanning
Where 3D laser scanning is required — for complex geometry, heritage buildings or high-accuracy requirements — this adds to the cost but significantly increases accuracy and completeness.
Location and access
We travel UK wide for every project. Travel costs are included in our quote — no hidden charges for distance.
Turnaround time
Standard turnaround is 5–10 working days from survey. Faster delivery can be accommodated — please mention your deadline when enquiring.

When You Need a Measured Survey
Measured building surveys are required at many stages of a project. Here are the most common scenarios where accurate survey drawings make a real difference.
Planning Applications
Local planning authorities typically require accurate existing and proposed drawings. A measured building survey provides the reliable base drawings needed for a complete planning submission.
Refurbishment & Extensions
Before any refurbishment or extension work begins, accurate existing condition drawings allow designers to understand the building and plan works with confidence.
Change of Use
Converting a building to a different use requires accurate as-existing drawings to assess compliance, plan layouts and demonstrate suitability to the planning authority.
Listed Building Consent
Works to listed buildings require detailed existing condition drawings as part of the consent application. Measured surveys provide the accurate base information required.
Asset & Record Drawings
Accurate floor plans and elevations are invaluable for facilities management, estate records and future maintenance planning — particularly where original drawings no longer exist.
Pre-Purchase Surveys
Verify the actual size and layout of a building before committing to a purchase or lease — particularly useful for commercial property acquisitions.
