Property Floorplan Extractor

The Property Floorplan Extractor is an Apify Actor that turns a property listing URL into structured, room-by-room data read straight from the listing's floorplan image. Paste a Rightmove or OnTheMarket link and get back every labelled room with its type, size in m², printed dimensions, and storey — plus bedroom count, total floor area, and balcony/garden flags.

Room-level data is the most valuable information on a property listing and the only part that is never published as text. Agents render it once, into a floorplan drawing, and it stays locked in that image. This Actor reads the drawing with AI vision and gives you the numbers as JSON.

Key Features

• Listing URL in, rooms out: Go straight from a live listing page to structured rooms — no manual image hunting, no separate OCR step.
• Search URLs supported: Point it at a search results page and it walks the pagination, opening every listing that publishes a floorplan.
• Per-room measurements: Room name as printed, room type, area in m², the original dimension text, and the storey each room sits on.
• Property-level rollups: totalRooms, bedroomCount, totalFloorAreaSqm, floors, hasBalcony, and hasGarden.
• Bring your own images: floorplanImageUrls accepts any public floorplan image, so the Actor still works for portals it does not support natively.
• Cost-aware crawling: Listings that never uploaded a plan are skipped before they are fetched.
• No API key required: AI vision is included — you do not supply or pay for your own model key.
• No login required: Works entirely on publicly reachable listing pages.

Why Extract Floorplan Data?

Portals publish a price, a postcode, and a bedroom count. They do not publish the size of the kitchen, whether the third bedroom actually fits a double bed, or how the space is distributed across storeys. That detail exists only inside the floorplan image, which means it is invisible to every filter, model, and spreadsheet downstream.

• Valuation and AVMs: Price per m² and room mix are far stronger predictors than bedroom count alone.
• Property portals and search: Build filters buyers actually want — "kitchen over 20 m²", "double bedrooms only".
• Lettings, BTR and HMO analytics: Check room sizes against licensing minimums across a whole portfolio.
• Renovation and construction: Estimate flooring, heating loads, and material quantities from room areas.
• Proptech and iBuyers: Normalise heterogeneous listings into a comparable room-level schema.
• Market research: Track how room mix and floor area vary by area, price band, and property age.

Who Is It For?

• Proptech and portal teams enriching listing databases with room-level attributes.
• Data scientists and quants building valuation, AVM, or comparables models.
• Letting agents and BTR operators auditing room sizes at scale.
• Surveyors and renovation companies pre-qualifying jobs from floor areas.
• Researchers studying housing stock, space efficiency, and layout trends.

How It Works

1. You supply Rightmove or OnTheMarket listing URLs, search URLs, or direct floorplan image URLs.
2. Search pages are read and every listing that publishes a floorplan is queued; listings without one are skipped.
3. Each listing page is parsed for its floorplan image and headline metadata (address, price, property type).
4. The floorplan image is downloaded and analyzed by AI vision, which transcribes every labelled room.
5. Areas are taken from the plan where printed, and otherwise derived from the printed dimensions.
6. One dataset row is pushed per floorplan image, with the floorplan set as imageUrl so it renders as a thumbnail in the Apify Console.

Pricing

This Actor uses pay-per-event pricing:

Event	Charged when
listing-scraped	A listing page is read for floorplan images
floorplan-analyzed	A floorplan image is sent to the AI vision model
room-extracted	Per individual room extracted from a floorplan

Listings without a published floorplan cost only a single listing-scraped event, and Rightmove search results are filtered before fetching so plan-less listings are mostly skipped entirely.

Notes and Limitations

• One row per floorplan image, not per property. Larger homes often publish a separate plan per storey. Raise maxFloorplansPerListing and group rows by listingId to assemble the whole property.
• bedroomCount reflects the plan, not the advert. It counts rooms labelled as bedrooms on the drawing, so it can differ from listingBedrooms when a plan labels staff bedrooms, studies, or annexe rooms that the agent does not market. Compare the two fields to spot these cases.
• Only labelled rooms are returned. Unlabelled spaces are deliberately not invented, so a plan that draws a bathroom without naming it will not produce a bathroom row.
• Areas are as accurate as the plan. Floorplans are marketing drawings; agents state that measurements are approximate. Rooms with no printed dimensions return areaSqm: null.
• totalFloorAreaSqm falls back to a sum. When the plan prints no gross internal area, the value is the sum of measured rooms, which excludes walls and unlabelled space and so reads low.
• Check confidence. Low-resolution, rotated, or heavily compressed plans return low; filter on this field for high-precision pipelines.
• Public data only. No login, account, or user-supplied credentials are involved.
