Floor Plans

What a floor plan shows

A floor plan presents a building as if the roof were removed and you looked straight down. Everything that matters about how a space works is captured in a single drawing: where the rooms sit, how they connect, where the doors and windows are, and how large each space actually is.

That combination makes the floor plan the most information-dense asset in property marketing. A photograph shows what a room looks like; a floor plan shows how the whole property fits together. Buyers, tenants, designers and builders all read plans for the same reason — they answer questions that photographs cannot.

• The position and size of every room
• Walls, doors, windows and openings
• Fixtures such as kitchens, bathrooms and built-in storage
• Room dimensions and total floor area
• The flow between spaces — hallways, landings and stairs

Types of floor plan

Floor plans come in several forms, and many properties are marketed with more than one. Choosing the right type depends on what you need the plan to do.

2D floor plans are the standard. A flat, to-scale drawing with room labels and dimensions is what portals expect, what buyers are used to reading, and what measurements and compliance work are based on. Every other type of plan is usually built from an accurate 2D drawing first.

3D floor plans add depth, perspective and furniture. They are easier for non-experts to visualise, which makes them popular for new builds, off-plan sales and premium listings where marketing impact matters more than raw measurements.

Interactive floor plans go a step further: each room becomes clickable, linking to photos, video, 360° tours and property information. Built with Planos, they work for single homes as well as building maps for developments, offices and venues.

Site plans show the building within its plot or wider development — useful for gardens, parking, outbuildings and new-build schemes.

Three ways to get your floor plan

Whether you want to draw it yourself, have it done for you, or improve a plan you already have, there is a route that fits.

Create. The floor plan app lets you draw and edit 2D plans in your browser — add rooms, walls, doors, windows and measurements, then export the plan for listings, brochures or the web. It is free to start and suits anyone comfortable spending a little time on the drawing.

Convert. If you already have something — a hand sketch from a viewing, a photo of an old plan, a PDF brochure or a blueprint — it can be converted into a clean, professional plan. This is the most cost-effective route for estate agents, landlords and homeowners who have measurements but not the time or software to draw.

Enhance. An existing 2D plan can be developed into a 3D visual, rebranded for your agency, or made interactive with clickable rooms and tours. You keep the accurate layout you already have and add the presentation layer on top.

Why floor plans matter for property

Listings with a floor plan consistently attract more interest than those without. A plan answers the first question every buyer or tenant has — does the layout work for me? — before anyone books a viewing. That self-qualification cuts wasted viewings and brings more serious enquiries.

For agents, offering professional plans also helps win instructions: vendors notice which agents present properties to a higher standard. For landlords and letting agents, plans set clear expectations with tenants and provide a record of the property layout.

Beyond marketing, accurate plans support renovations, extensions, valuations, lease documents and compliance work — one drawing serving many purposes over the life of a property.

How to read a floor plan

Floor plans use a shared visual language, and once you know a handful of conventions you can read any plan with confidence.

Walls are drawn as solid lines, with external walls usually thicker than internal ones. Doors appear as a straight line with a quarter-circle arc showing which way they swing. Windows are shown as thin breaks or parallel lines within a wall. Stairs are a run of parallel lines with an arrow marked "up". Kitchens and bathrooms show outlines of fixed units — sinks, hobs, baths and WCs — so you can see how each room functions.

Alongside the symbols, look for the room dimensions, the total floor area, and a scale bar or stated scale. Together they tell you not just the shape of the property but its real size. Our floor plan symbols guide covers the full set of conventions.

Measurements, scale and accuracy

A floor plan is only as useful as its measurements. A good plan is drawn to scale, shows dimensions for each room, and states the total floor area — the headline figure buyers and tenants look for.

For property marketing, a plan drawn to scale from sensible measurements is usually sufficient. For valuation, lending or compliance, area should be calculated to a recognised standard: GIA (Gross Internal Area) is common for residential marketing, while NIA (Net Internal Area) is used for commercial valuation. Whichever standard applies, it should be stated on the plan.

If you are converting an existing sketch, image or PDF, the accuracy of the finished plan depends on the accuracy of the source — supplying correct room dimensions is the single biggest factor in getting a reliable result.

How much does a floor plan cost?

Cost depends on the type of plan, the size of the property and how it is measured. As a rough guide for UK residential property: converting a sketch into a professional 2D plan typically costs from around £15–£40; a measured survey with a professional plan costs more because someone visits the property; 3D plans carry a premium on top of the 2D drawing; and interactive plans are usually quoted per project.

Creating a plan yourself online is free to start, which suits one-off needs — though it takes your time and requires accurate measurements. If you produce plans regularly, converting sketches or a subscription usually works out the most economical. See the full floor plan cost guide for detailed pricing.

Floor plans and AI

AI is changing how floor plans are made. The slow, manual parts of the work — reading an existing drawing, recognising rooms and walls, cleaning up lines, calculating areas — are exactly the tasks AI is suited to.
