No Documentation for Your House?

Do not start by redrawing immediately. First determine what records exist and whether the current building matches known approvals and use.

Search available records

Check previous owners, designers, the building authority, archives, managers and historic contracts.

Inspect current conditions

Record extensions, attic conversions, garages, layout changes, use changes and building services.

Choose the correct document

A passport may restore missing records; refurbishment usually needs a more detailed survey; unauthorised changes may require a separate legal process.

Confirm requirements

For uncertain cases, consult the authority or an authorised designer before ordering the final scope.

Create a controlled archive

Store PDFs, editable source files, decisions, inspections and photographs with clear names and revision dates.

Need deliverables that remain usable

Before commissioning the work, define the purpose, survey scope, required accuracy, deliverable formats and acceptance checks in writing. DigiStav provides surveying, building records, 2D documentation, point clouds and BIM-ready outputs for buildings, infrastructure and industrial assets. The scope should always follow the intended use rather than a generic package.

This article provides general technical information. It is not a substitute for project-specific legal, surveying, engineering or professional-authorisation advice.
