A measured building survey is the right service when you need traditional architectural drawings (plans, elevations, sections) of an existing building. If your project also needs a registered point cloud, a Revit BIM model, MEP scan-to-BIM or a clash-detection deliverable, our 3D laser scanning service is the better starting point.
Measured building surveys provide the accurate existing building information needed for design, planning and construction work. At THS Concepts, we carry out measured surveys for residential, commercial and specialist properties, producing clear floor plans, elevations, sections, roof plans and as-built drawings.
Depending on the project we capture site data using total stations, conventional measurement and 3D laser scanning. For projects centred on point cloud or BIM deliverables rather than 2D drawings, see our dedicated 3D laser scanning survey service.
Our measured survey service is used for house extensions, refurbishments, fit-outs, lease plans, heritage documentation and commercial redevelopment projects. Drawings are typically supplied in DWG and PDF format, with E57 and Revit outputs available where needed.
If you need a measured building survey quote, send us the property address, required drawings and any timescales, and we will confirm the most suitable survey scope for your project.
A measured building survey provides accurate, to-scale information that supports a wide range of property and construction projects. Whether you’re a homeowner, architect or developer, it’s often the first step in any successful design or renovation.
Planning Applications & Building Control
Local authorities and architects rely on measured surveys to produce precise drawings for planning submissions and building control approval. Accurate existing plans reduce design errors and prevent costly re-submissions.
Property Extensions & Renovations
When extending or altering a home or commercial property, a measured survey ensures your designer works from exact dimensions and structural layouts. This gives confidence that new works will integrate seamlessly with the existing structure.
Lease Plans & Boundary Verification
For property transactions, lease agreements or land registry submissions, measured surveys provide the legal accuracy needed to confirm boundaries, floor areas and shared spaces, particularly valuable in complex London developments.
Heritage & Conservation Documentation
Historical and listed buildings often require detailed measured drawings before restoration. Our laser scanning process captures every architectural feature while preserving delicate structures through non-contact measurement.
Interior Design & Space Planning
Designers and fit-out contractors use measured surveys to plan lighting, furniture layouts and bespoke joinery accurately. High-precision floor plans allow for better visualisation and efficient use of space.
Facilities Management & Refurbishment Planning
Building owners and managers use measured surveys to maintain accurate as-built records, simplifying future refurbishments, maintenance scheduling and asset management.
Every project starts with reliable data. By commissioning a measured survey in London, you can make informed design and construction decisions based on precise, verifiable information.
We carry out measured building surveys for a wide range of clients, from single-property residential projects through to larger commercial and specialist buildings.
For house extensions, refurbishments and renovation planning, a measured survey provides the accurate floor plans, elevations and sections needed for design and planning work.
We provide reliable existing building information to support concept design, planning drawings, technical design and coordination.
Measured building surveys help developers assess existing properties, plan redevelopment works and coordinate design information across project teams.
We survey offices, retail units and other commercial spaces to support fit-out design, refurbishment planning and space reconfiguration.
Historic and listed buildings often require accurate existing records before repair, restoration or alteration work begins.
We also support engineers, project managers, lease plan requirements, asset teams and other consultants who need dependable as-built building information.
The examples below show the type of information a measured building survey can provide for design, planning and construction work. If you require specific examples, please visit out measured survey example drawings page.
Every measured building survey follows a clear process, from on-site capture through to checked drawing production and final issue.
Our surveyors attend site and capture the building using the most suitable combination of 3D laser scanning, total station observations and hand measurement checks. Depending on the project, we record internal layouts, external elevations, stairs, openings, floor level changes, ceiling features and other key elements needed for the agreed drawing package. We also take site photographs and notes to support drafting and later quality checks.
Once the survey is complete, we register and process the raw data in specialist software to create a coordinated and usable survey dataset. At this stage, we check scan coverage, alignment, control information where applicable, and any site notes or photographs needed to confirm unclear areas. This quality-control stage helps ensure the final drawings are based on reliable, properly reviewed information.
Our team converts the checked survey data into the agreed deliverables, which may include floor plans, external elevations, internal elevations, sections, roof plans, reflected ceiling plans, point cloud outputs or BIM models. Drawings are produced to the required scope and level of detail so they can be used confidently by architects, designers, contractors and other consultants.
We issue the completed drawing package in the agreed formats, typically DWG and PDF, with point cloud or model files provided where required. If anything needs clarification, we can review the outputs with you or your design team to make sure the information is clear and suitable for the next stage of the project.

Measured building survey costs depend on the size of the property, the required drawings, the level of detail, site access and whether additional outputs such as point cloud data or BIM models are needed. As a guide, smaller residential measured surveys often start from around £600 + VAT, while larger, more detailed or more complex buildings are quoted based on the agreed scope.
To prepare a quotation, we usually need the property address, the building type, the drawings or outputs required, any known access constraints, and your timescales. If you already have a brief, mark-up or example drawing requirement from your architect or consultant, you can send that as well.
Once we have reviewed the scope, we will issue a clear quotation covering the survey work, drawing production and standard quality checks. For broader pricing guidance, you can also view our Measured Survey Cost Guide or use our Instant Estimate Tool for an indicative figure.
Our quotations clearly set out the agreed survey scope, deliverables and cost, so you know exactly what is included before any work begins.

Answers to the most common questions about our measured survey service, deliverables and quotation process.
A measured building survey records the existing layout and geometry of a property so accurate drawings can be produced for design, planning and construction work. Typical outputs include floor plans, elevations, sections and roof plans. For a fuller explanation, see our What is a measured survey? guide
The terms are often used very similarly, but an as-built survey is more commonly used to describe a record of what has actually been built, often after construction or alteration work. For a more detailed explanation, see our as-built survey guide.
Depending on the scope, we can provide floor plans, elevations, sections, roof plans, reflected ceiling plans, point cloud data and BIM models. You can also view our measured survey drawing examples to see common output types.
The cost depends on the size of the property, the drawing types required, the level of detail, access conditions and whether point cloud or BIM outputs are needed. For a more detailed pricing breakdown, see our measured survey cost guide.
The most useful information includes the property address, building type, required drawings, any access constraints, and your timescales. If you already have an architect’s mark-up or brief, you can send that as well.
Yes. These are some of the most common outputs requested as part of a measured building survey. We can tailor the drawing package to suit the project scope, from basic floor plans through to more detailed elevation and section packages.
Yes. We regularly survey occupied homes and working buildings. Access conditions can affect the detail that can be captured in some areas, so it is helpful to mention any restrictions when requesting a quote.
We undertake measured building surveys in the counties surrounding our offices. These include:
However, we have been much further afield within the UK and internationally. We have undertaken surveying work as far away as Liberia in West Africa.
