At Line Surveying, we deliver accurate measured building surveys across London for residential, commercial and mixed-use properties. Our surveys provide precise floor plans, elevations and sections to support planning applications, architectural design and redevelopment projects.
Using advanced laser scanning and total station technology, we capture detailed, reliable building data — ensuring your drawings reflect the property exactly as it exists.
Our experienced survey team combines modern surveying technology with practical building expertise to deliver dependable measured survey drawings.
Every project follows a structured workflow to ensure consistent quality and accuracy suitable for:
We capture precise measurements to create reliable floor plans, elevations and sections that reflect true building dimensions.
Architects rely on measured surveys to develop extensions, refurbishments and structural alterations.
Accurate base drawings prevent design conflicts and costly site variations later in the project.
Residential homes, commercial buildings, retail units, offices and mixed-use developments.
Supplied in DWG, PDF and other requested formats.

Answers to common questions about how our surveys are carried out, what to expect on site and how the process works.
Typically floor plans, elevations and sections. We can also provide roof plans and site layouts if required.
Most residential properties are surveyed within a few hours. Larger commercial sites may require additional time.
We supply drawings in DWG, PDF and other requested formats.
Yes. We undertake surveys for offices, retail, industrial and mixed-use properties.
We use professional-grade equipment to deliver highly accurate survey data suitable for design and planning purposes.
We provide professional measured building surveys throughout Greater London and surrounding areas.
The right measured survey starts with the drawings your architect needs. Agree the floors and external faces to be covered, the positions of sections and any roof or site information required. Send existing plans if available and mark the areas affected by your proposal.
Floor plans describe the building in plan; elevations record its external faces; sections explain the relationships between levels and spaces. The quote should identify which drawings are included. Roof plans, additional detail and point cloud outputs can be discussed as part of the brief.
DWG and PDF drawings support common design workflows. Confirm units, drawing scale, layer requirements and any project datum before capture. Where garden levels or external site features matter, coordinate the building survey with a topographical site survey.
Survey coverage depends on access and visibility. Tell us about locked rooms, roof spaces, occupied areas or features hidden by storage. Concealed construction is not established by measuring visible surfaces, and a measured survey is not a structural condition assessment.
Use our survey brief checklist for architects and property preparation guide to plan the visit. For model-based work, see Revit and BIM survey deliverables.
