Find your estate
Whatever you answer for, start here.
From flight to funded plan
We capture what nobody can safely reach.
A CAA-approved drone flies the whole envelope - roof, facade, every elevation - in hours, with no scaffold and no one working at height.
Every image becomes data.
Thousands of images resolve into one measured, located 3D record of the building. Not photos in a folder - structured intelligence.
AI finds the risk. People confirm it.
The Ovrsite engine detects and grades every defect across the full set, then our team validates each finding and removes the false positives.
Map it to the duties you answer for.
Every finding ties back to the regulation behind it - the Building Safety Act and the Golden Thread, fire safety, Awaab's Law, MEES - graded by risk, so you see what the law requires, not just what the roof needs.
Risk you can act on. Spend you can defend.
Findings become a costed, prioritised CAPEX plan - worst risk first, safe deferrals justified, every pound traceable to a dated finding.

001The problem
The condition data was never good enough to bet millions on.
Most property teams rely on periodic stock-condition surveys, ground-level walkovers, or contractor-led assessments that miss the roof, the upper facade and the building envelope. The areas where the most expensive failures start.
The result: incomplete records, reactive maintenance, undefended capital plans, and findings that do not survive scrutiny from a board, a funder, or a regulator.
Ovrsite closes that gap. We give you one current, independent record of every asset in the portfolio, with the findings graded and the spend already prioritised.
002What Ovrsite changes
Three jobs, done from one record.
Decisions stop being instinctive. Budget stops being political. Risk stops being a surprise.
Decision making: defensible, not instinctive
Prioritise spend on context, constraint and evidence, never a hunch. Every recommendation traces back to dated imagery and a measured finding.
Budget protection: every pound, justified
Direct CAPEX to the assets and interventions with the greatest impact. Defer what can safely wait and show why.
Risk reduction: see it before it costs
Find where risk concentrates across a portfolio and act early, while a repair is still a repair and not a claim.
003Capabilities
One capture. Six outputs.
A single drone inspection feeds every line below. You commission once and the data works across compliance, planned maintenance and the board pack.
Roof & building envelope
Flat roofs, pitched systems, membranes, drainage and standing water captured at high resolution, with no scaffold and no one at height. The whole roof, not the corners anyone could safely reach.
Thermal anomaly detection
Radiometric thermal capture surfaces anomalies the eye cannot see, the kind that can point to trapped moisture or heat loss, flagged for investigation.
Golden Thread evidence
Dated, located, structured condition records that feed the Golden Thread and the building safety case for higher-risk buildings.
CAPEX forecasting
Findings convert into a costed, time-phased plan. Worst risk first, deferrals justified, ready for the board and the lender.
AI detection, human-validated
The Ovrsite AI engine detects and grades defects across thousands of images, then our team validates every finding. Purpose-built computer-vision detection, not a repurposed language model.
Facade & external wall
Elevation-by-elevation condition of cladding, render, brickwork, sealant and movement joints. Evidence that supports PAS 9980 and EWS work.
004The platform
Atlas. The single source of truth for your estate.
Every inspection lands in Atlas, mapped to the asset, the elevation and the date. Filter by building, by severity, by cost. Track remediation from raised to resolved. Compare year on year. One login, one record, every stakeholder.
- Asset managers see the whole estate at a glance, ranked by risk and by spend
- Compliance leads pull the dated, located evidence a regulator asks for
- Finance and the board see where the money should go, and why
- One source of truth for everyone, not six spreadsheets

005Who we work with
Different duties. One source of evidence.
REITs, housing associations, NHS trusts, councils and FM providers all manage different obligations. The need for independent, current condition data is the same.
Higher-risk & housing
Golden Thread evidence, Awaab's Law response, and condition data for G15, housing associations and HRB dutyholders.
Commercial & REITs
Portfolio roof and facade risk, CAPEX forecasting and MEES planning for landlords, REITs and asset managers.
NHS estates & public sector
Backlog maintenance evidence and roof condition across hospital estates, campuses and public buildings.
Student & PBSA
Envelope and roof condition for purpose-built student accommodation, ahead of the summer turnaround window.
Local authorities
Independent stock condition evidence for council housing, schools and the wider corporate estate.
FM providers
The inspection and evidence layer behind your service. White-label capture, your client relationship.
006How it works
From flight to board pack in four steps.
One pipeline takes your estate from aerial capture to verified findings, a defensible report and a costed plan. No spreadsheets in between.
Capture
A CAA-approved pilot flies the asset and records high-resolution visual, thermal and, where needed, 3D data. No scaffold, no access towers, no closures.
Full-coverage capture
Analyse
AI models detect and grade defects across the full image set, measuring and locating each one rather than sampling.
Located, graded findings
Validate
Our team checks every finding the AI raises, removes false positives, and writes it up to RICS-aligned reporting conventions you can put in front of a board.
Human-validated findings
Act
Findings land in Atlas as a costed, prioritised plan. You decide what to fix now, what to defer, and you can show the reasoning.
Costed CAPEX plan

004FAQ
Questions estates teams ask us
Ovrsite is a UK building-intelligence company. We use drones to capture the whole building envelope (roof, facade and thermal), a purpose-built computer-vision engine to detect and grade defects, and human quality assurance to verify every finding. The result is an independent, defensible record of building condition, delivered in our Atlas platform for institutional property portfolios.
Atlas is the Ovrsite platform and system of record. Every inspection, finding, compliance flag and pound of planned CAPEX is graded, located, dated and kept live in one place, so the condition record stays current between visits and holds up in front of a board, a lender or a regulator.
No. Drones are how we capture data quickly and without working at height. The product is building intelligence: an independent, structured record of condition you can act on and defend. The flying is a means, not the point.
Both. A purpose-built computer-vision engine detects, measures and grades defects across thousands of images, then our team verifies every finding and removes false positives before it reaches you. It is a real detection engine with human validation, not a repurposed language model.
A traditional inspection samples what a person can safely reach and writes it up as a document. Ovrsite captures the whole asset at high resolution, grades every finding, locates it on the building, and keeps it live in Atlas so the record stays current between visits.
No. We give them better evidence. Many clients use Ovrsite as the independent capture and analysis layer underneath their own consultants or FM provider.
From a single landmark building to estates in the thousands. The platform earns its place fastest where the same questions repeat across many assets and the cost of being wrong is high.
See the evidence on your own estate.
Most teams start with a single building or a conversation about what they need to know. We will scope the work, inspect the site, and walk you through exactly what we find. No retainer, no platform commitment upfront.
