Find the site nobody else has spotted yet
Splittable gardens, backland plots, conversions, extensions and under-priced land — across listings that are actively for sale and off-market opportunities others never see. SiteSense analyses each one end-to-end with AI, then hands you the owner's name and a personalised letter that's ready to post.
Opportunity detection · site feasibility · owner identification · tracked outreach — in one place.

Incumbents bolt AI onto legacy filtering. SiteSense is built around the engine — genuine, explainable opportunity scoring, vision-model property assessment, and outreach that goes all the way to a tracked letter in the post.
Two ways to find the next site
Whatever the market shows you, and everything it doesn't.
Actively for sale
We scan every new listing across the major portals and land sites and AI-review it for potential the listing photos never mention — a garden big enough to split, a building ripe for conversion, unused permitted development, or land that's simply under-priced.
Off-market
Probate, long-vacant and council-tax empty homes, company distress and overseas-owned watchlists surface motivated owners before anything reaches Rightmove — then we help you reach them directly and compliantly.
Everything from spotting to sending
One platform across the whole sourcing workflow — not another portal.
AI opportunity detection
14 transparent scorers surface what others miss — garden & backland plots, upward and rear extensions, Class Q/MA conversions, HMO and flat splits, and more. Every score is explainable, never a black box.
Scans for-sale and off-market
Every new listing across the portals and land sites is AI-reviewed for hidden upside — while probate, vacancy and distress watchlists surface owners before anything lists.
Vision-model assessment
Claude reads listing photos and floorplans to score condition, estimate refurb spend, extract floor area, and flag extension, split or conversion potential.
Full site feasibility
Planning history, constraint checks, comps, AVM, GDV per scheme, build-cost and profit projection — auto-generated into a white-label PDF appraisal.
Owner ID + tracked outreach
Identify the registered owner, generate an AI-personalised letter from the full site analysis, post it via Stannp, and track every call, scan and reply in the pipeline.
Sensible pricing
80% of LandTech's functionality at a fraction of the price — built on modern, fast, mobile-friendly UX instead of a decade-old codebase.
14 scorers, every residential play
SiteSense runs a battery of transparent, rule-based scorers over every property and parcel — from splitting a garden to converting a barn. Each returns a 0–100 score with the recommended scheme, a confidence band, the top risks, and nearby comps with planning references.
Garden & backland plots
Split oversized gardens or land-locked parcels into new dwellings.
Bungalow uplift
Class AA storeys + rear extension + outbuilding, combined into one score.
Upward & rear extensions
Permitted-development volume the current owner never used.
Class Q / MA conversions
Agricultural and commercial buildings turned into homes.
HMO & flat conversion
Article-4-aware HMO yield and period-property splits.
Off-market & adjacent consents
Probate, vacancy, distress and nearby approvals.
- ▸ Every point is shown and sourced — never a black box.
- ▸ Eligibility is rule-based and auditable; AI handles the narrative.
- ▸ Values are clearly indicative, never an RICS valuation.
