What Is a Floor Plan Survey?
A floor plan survey (officially a measured building survey) is a professional service where a qualified surveyor visits a property to capture precise dimensions using laser scanners or total stations, producing accurate 2D/3D drawings of internal and external spaces. It's used for planning applications, architectural design, lease area calculations, BIM projects, and refurbishment.
