What Is a Floor Plan Survey?
A floor plan survey (also called a measured building survey) is a professional service where a qualified surveyor visits a property to take precise measurements and produces accurate, scaled drawings of the layout. It differs from a structural or homebuyer survey — it's about capturing the as-built geometry for design, refurbishment, planning, building control, or lease registration.
