3D Building Models & Point Clouds
Drone 3D Photogrammetry
Survey-grade drone photogrammetry that turns hundreds of overlapping aerial images into accurate, measurable 3D models and point clouds, captured safely from the air with no scaffolding and no disruption.
EXPLAINER
DRONE 3D PHOTOGRAMMETRY, EXPLAINED
Drone photogrammetry captures hundreds of overlapping, high-resolution aerial images of a building or site and processes them into a georeferenced 3D model, point cloud and orthomosaic map. Because every point has a real-world position, you can take true distances, areas, heights and volumes directly from your desktop, without returning to site.
It is a fast, accurate and non-contact alternative to traditional measured surveys for architects, surveyors, developers, conservation teams and asset managers. Using RTK positioning and ground control points, we achieve horizontal accuracy down to 1cm, and every survey is flown by a CAA-registered pilot and processed by experienced specialists.

WHERE 3D PHOTOGRAMMETRY MAKES THE DIFFERENCE
Survey-grade measurements
Take true distances, areas, heights and volumes directly from the model, with RTK positioning delivering horizontal accuracy down to 1cm.
Detailed 3D building models
Reconstruct roofs, façades and whole sites as textured 3D models you can rotate, inspect and share with your project team.
Point clouds & BIM input
Export dense point clouds and CAD-compatible data, ready to drop into your BIM, design and restoration planning workflows.
Georeferenced mapping
Produce high-resolution orthomosaic maps and digital surface models that sit accurately on your site plans.
No scaffolding, no disruption
Capture every elevation, roof pitch and hard-to-reach detail from the air, with no access equipment and no working at height.
Repeat surveys and change tracking
Revisit the same site at agreed intervals and compare models side by side to track progress, movement and condition over time.

HOW A 3D PHOTOGRAMMETRY SURVEY WORKS
-
01
Survey planning
We agree your required outputs and accuracy, then plan the flight, ground control and airspace so the survey is safe, compliant and focused on what matters to you.
-
02
Aerial image capture
We fly automated, overlapping flight paths, capturing hundreds of high-resolution images of every roof, elevation and feature.
-
03
RTK and ground control
RTK positioning and ground control points tie the model to real-world coordinates, delivering survey-grade accuracy.
-
04
Photogrammetric processing
Specialist software aligns the images into a dense point cloud, textured 3D model and orthomosaic, typically within 24 to 48 hours.
-
05
Measurable deliverables
You receive your 3D model, point cloud and mapping in formats that suit your workflow, plus a clear report with measurements where required.
IN_THE_FIELD
3D PHOTOGRAMMETRY IN ACTION
A photogrammetry model gives everyone on the project the same accurate picture of the building, from restoration planning and BIM input to multi-year asset management. Pair it with thermal imaging or a drone property inspection for a complete view of your building's condition.
LAUNCH_FAQ
3D PHOTOGRAMMETRY FAQs
How accurate is drone photogrammetry?
Using RTK positioning and ground control points, we can achieve horizontal accuracy down to 1cm and vertical accuracy within 2 to 3cm. Photogrammetry precision can be as fine as 20mm, depending on the building and the level of detail required.
What is the difference between a 3D model and a point cloud?
A point cloud is a dense set of measured points that accurately records the shape of a building, ready for measurement and BIM workflows. A 3D model is a textured, photo-realistic surface built from those points, ideal for visualising, inspecting and presenting your site.
What deliverables do I receive from a photogrammetry survey?
Depending on your project, deliverables can include interactive 3D models, 3D point clouds, orthomosaic maps, digital surface models and CAD-compatible files, with raw data supplied on request. We agree the formats with you before we fly.
Do I need scaffolding or roof access?
No. The drone captures every elevation and roof from the air, so there is no scaffolding, no access equipment and no working at height. This makes photogrammetry faster, safer and lower cost than traditional survey methods.
How long does a 3D photogrammetry survey take?
On-site time ranges from around 20 minutes for a straightforward house to a few days for large or complex sites. Data processing typically takes 24 to 48 hours, with full reports delivered within 3 to 5 business days.
Which areas do you cover?
We carry out 3D photogrammetry surveys across London and UK-wide. Get in touch with your location and we will confirm availability.
