As-Built Drawings for UK Architects

Accurate, professionally prepared as-built drawings for UK architectural practices — documenting existing buildings for planning, Building Regulations, refurbishment, and property records.

What we deliver

At JDS Designs, we provide accurate and professionally prepared As-Built Drawings for UK architectural practices, helping you document existing buildings with confidence. Whether for planning applications, Building Regulations, refurbishment, extensions, change of use, or property records, our drawings accurately reflect the completed or existing condition of a building.

Working from measured survey data, hand sketches, site notes, point cloud data, photographs, or marked-up drawings, we produce detailed floor plans, elevations, sections, roof plans, and site plans in AutoCAD or Revit. Every drawing is prepared to your office standards and checked for accuracy to ensure it can be seamlessly incorporated into your project workflow.

What is included

  • As-built floor plans — showing the building as constructed, with all site variations from the issued drawings noted
  • As-built elevations — exterior faces updated to reflect constructed materials, openings, and levels
  • As-built sections — vertical sections through the building updated to reflect actual construction
  • Red-line mark-up to as-built — your contractor-marked PDFs or drawings converted to clean CAD
  • Existing condition survey drawings — where a measured survey is required as the basis
  • As-built schedules — door, window, and room schedules updated to reflect final construction
  • Coordination between structural, architectural, and services drawings where required
  • Drawing revision schedule — showing which elements changed between issued-for-construction and as-built
  • Delivered in DWG and PDF format

Who this service is for

UK architectural practices that need to produce as-built documentation at the end of a construction project — for building control final sign-off, for handover to the building owner, or for the project's O&M manual. Particularly relevant for practices that are managing multiple projects simultaneously and need to outsource the post-construction documentation phase without delaying live project work.

Also used by practices that have been engaged to work on an existing building and need an accurate as-built record of the current condition as the starting point for a new commission.

Questions

Frequently asked questions

  • We can work from verbal site notes and photographs where formal redlines are unavailable. The accuracy of the as-built drawing is limited by the quality of the information provided — we will confirm the approach at briefing and flag any uncertainty.

  • Yes — where the starting point is a physical building rather than an issued drawing set, we produce as-built drawings from the measured survey information you provide.

  • No — JDS operates remotely as an outsourced studio. We produce drawings from survey information you supply. For the survey itself, we recommend engaging a measured survey specialist.

  • Yes — as-built drawings showing the existing condition of the building form the 'existing drawings' required for a planning application for further alterations or extensions.

  • As-built drawings are produced at the end of a construction project, updated from the issued-for-construction set. Existing drawings are produced at the start of a new project to record the current condition of an existing building — often a building that has never had accurate drawings produced.

  • Yes — where the structural engineer and services consultant have also produced as-built versions of their drawings, we can coordinate the architectural as-built with those to produce a coherent combined record set.
