Definition
A floor plan is a scaled drawing that shows a building or room as seen from directly above, as if the roof were removed. It maps out the layout of walls, doors, windows, and spaces so you can understand how a building is arranged.
Floor plans are one of the most widely used documents in architecture, real estate, and construction because they turn a three-dimensional space into a clear, easy-to-read map. They can show a single room or an entire multi-storey building.
In everyday terms, a floor plan is the blueprint of a space that tells you where everything is and how the areas connect.
How It Works
Traditionally, floor plans were drawn by hand from tape-measure readings. Today they are usually produced in CAD or BIM software, and increasingly they are generated from reality-capture data. When a space is scanned with a laser scanner, the resulting point cloud can be sliced at a set height to reveal wall positions, which are then traced into an accurate plan.
A finished floor plan is drawn to scale, meaning distances on the drawing correspond to real distances in the building. Symbols and annotations mark features such as doors, stairs, fixtures, and dimensions so the plan communicates clearly to builders, designers, and clients.
Applications
Floor plans are used in construction, renovation, real estate marketing, interior design, facility management, and emergency planning. Architects use them to design layouts, contractors to build accurately, real estate agents to market properties, and facility managers to plan space usage and maintenance. Scan-based floor plans are especially valuable for renovating older buildings where original drawings are missing or outdated.
Benefits
- A clear, standardized way to communicate a building layout.
- Accurate spatial reference for design and construction.
- Faster, more reliable creation when derived from laser scans.
- A useful tool for space planning and facility management.
- Better decision-making for renovations and fit-outs.

Frequently Asked Questions
What is included in a floor plan?
A typical floor plan shows walls, doors, windows, room layouts, and dimensions, and may include fixtures, furniture, and annotations.
How are floor plans made from a laser scan?
The scan produces a point cloud, which is sliced horizontally at a set height so wall lines can be extracted and traced into an accurate, to-scale plan.
What is the difference between a floor plan and a blueprint?
A floor plan is one type of drawing showing the layout from above, while a blueprint traditionally refers to a full set of technical construction drawings that may include many plans.
Are scanned floor plans accurate?
Yes, floor plans created from laser scans reflect the building exactly as it exists, which is often more accurate than old or hand-measured drawings.
