What is an Internal Survey?
An Internal Survey (also known as an interior survey or measured internal survey) provides highly accurate, to-scale floor plans that outline the existing structure of a property. These plans can include:
Bird’s-eye view of the entire area
Get a complete, top-down perspective of your property, ensuring every space is accurately mapped for seamless planning and design.
Wall positions, dimensions & total square meters
Every wall is precisely measured, providing exact room dimensions and total area calculations for accurate layouts.
Floor levels & ceiling heights
Detailed elevation data captures floor variations and ceiling heights, helping architects and builders create designs that fit perfectly.
Door & window positions
Know exactly where doors and windows are located, ensuring optimal design, natural lighting, and smarter space utilisation.
Stairs & fixed furniture
Identify staircase locations, built-in cabinetry, and other permanent fixtures.
Electricity points & utilities

Whether you need a basic outline or a highly detailed plan, our surveys give you the clarity you need to move forward with confidence.
