3D Digital Twin Capture & Processing for Heritage and Conservation
Non-invasive documentation using drone photogrammetry, SLAM LiDAR and 3DGS visualisations
Preserving history with drone technology
Heritage conservation increasingly relies on accurate, repeatable digital records. We capture and process high-resolution aerial imagery and 3D scan data to create photorealistic 3D digital twins of historic sites — ideal for condition review, conservation planning, stakeholder consultation and public engagement.
The highest levels of detail captured in a web viewable 3D model
Our web-viewable 3D models are built for close inspection, not just a quick visual. Using high-resolution capture and careful processing, we create models that hold up when you zoom in — revealing fine surface detail and accurate geometry across façades, roofs and complex structures.
The result is a
shareable, browser-based 3D experience that helps teams review condition, plan work and communicate clearly without extra site visits.
What is a 3D digital twin for heritage and conservation?
A 3D digital twin is a high-fidelity virtual model of a building, structure or site. Created from drone imagery and 3D scanning, it allows you to:
- Inspect architectural detail without repeated site visits
- Review hard-to-reach areas safely and efficiently
- Create a clear “baseline” record for conservation and monitoring
- Share a single, consistent dataset with project teams and stakeholders
- Support restoration planning and interpretation work
- Preserve an accurate record for incident response and recovery
Watkins Hall - Lincoln Minster School - 3D Capture
The brief for this commission was primarily to produce scaled 2D orthographic elevations of this historic building for a planning submission. In addition, a highly detailed 3D model was created as part of the overall project deliverables.
This type of spatial data is increasingly welcomed by local authority planning departments, as it provides improved tools for assessment and decision-making. Interactive 3D models allow officers and other stakeholders to visualise the property in detail directly within a web browser, whether on a laptop or a mobile device.
In addition, the resolution of these models is often sufficient to identify and highlight many visible defects without the need for a separate, costly condition survey. While a more thorough, in-person inspection will still be required before any remedial works are specified or undertaken, the convenience of readily accessible data should not be underestimated.
Our Capture Methods
- Drone Photogrammetry: We fly structured capture missions to produce dense, high-detail datasets for highly detailed textured meshes, orthomosaics and measurable visuals.
- SLAM LiDAR Scanning (ground-based): Ideal for interiors and complex spaces, SLAM LiDAR rapidly captures geometry for point clouds and spatial understanding, even in areas where GNSS is limited.
- 3DGS (Gaussian Splatting) Visualisations: For immersive, photoreal viewing (especially interiors), 3DGS can deliver fast-loading, “as-you-stand-there” visualisation that’s ideal for collaboration and presentations.
St Peter and St Paul's Church - Dry Drayton - Cambridgeshire
St Peter and St Paul's Church in Dry Drayton, Cambridgeshire, is a historic parish church with origins dating back to the 13th century. Built in the Gothic style, the church features a medieval tower, a nave with 14th-century arcades, and later Perpendicular-style windows. The church underwent restorations in the 19th century, preserving its historic character while adapting to modern needs.
Inside, notable features include a 15th-century font, remnants of medieval wall paintings, and several memorials to local families. The churchyard contains historic gravestones, adding to its heritage significance.
All Saints Church - Covington - Huntingdon
All Saints’ Church in Huntingdon, Cambridgeshire, has a rich history dating back to the medieval period. The current building primarily dates from the 15th century, though earlier churches may have stood on the site. Built in the Perpendicular Gothic style, it features a striking west tower, large clerestory windows, and elegant stonework.
The church underwent significant restorations in the 19th century, preserving its historic features while accommodating modern congregational needs. Inside, it houses notable memorials, including tributes to prominent local figures, and a finely crafted font.
Church of St James Ruins - Bawsey - Kings Lynn
The hauntingly beautiful ruins of St. James' Church in Bawsey, near King's Lynn, stand as a testament to centuries of history, resilience, and mystery. Perched on an elevated site that once overlooked an estuary of the Gaywood River, the church dates back to the early 12th century and is believed to have originally been a Late Saxon minster.
The site’s rich past, coupled with its striking architectural remnants, made it an ideal candidate for our latest 3D modeling project. Using state-of-the-art drone technology, we meticulously captured high-resolution aerial imagery to create an accurate and immersive digital reconstruction of the ruins.
Bawsey was once a thriving medieval village, but as the landscape changed and water levels receded, its population dwindled. By 1517, the church was likely no longer in use, and records suggest it had already fallen into ruin by the late 18th century. Today, the site consists of imposing stone walls, a towering Norman archway, and remnants of a central bell tower, all constructed from locally sourced carrstone, flint, and limestone.
The church gained wider attention in 1998 when the ‘Time Team’ television programme conducted an excavation, unearthing a female skeleton with evidence of cranial injuries. Initial theories speculated she might have been a victim of a Viking raid, but further analysis suggested that the wounds resulted from an ancient surgical procedure known as trephination, performed over 1,300 years ago.
3D Digital Twin FAQs
How accurate are your models?
Accuracy depends on the site, capture method and the intended use. If you need the model to support reliable measurements, we’ll discuss scaling and control during scoping so the outputs match your requirements.
Can the model be used for measurements?
Yes — when the project is scoped for it. Where measurement-grade outputs are required, we’ll use appropriate capture planning and scaling/control so the dataset is suitable for the level of confidence you need.
Do you scan interiors as well as exteriors?
Yes. We capture exteriors with drone photogrammetry and can capture interiors using SLAM LiDAR and/or 3DGS visualisations, depending on access and the outcomes you want.
What will we receive at the end of the project?
Typically you’ll receive a web-viewable 3D model link for easy sharing, plus agreed deliverables such as point clouds, textured meshes, orthomosaics or still imagery. We’ll confirm formats and structure during scoping.
Do you provide CAD/BIM models (DWG/Revit/IFC)?
We can supply the underlying point cloud/mesh datasets to support CAD/BIM creation. If you need a specific downstream workflow, tell us what software you use and we’ll advise the best output route.
How long does capture and processing take?
Capture is often completed in a single visit, depending on site size and access. Processing time varies with complexity and deliverables, but we’ll confirm expected turnaround once the scope is agreed.
What affects the cost?
Key factors include the size and complexity of the site, whether you need interior and exterior capture, the level of accuracy required, the type of outputs, and any hosting or ongoing update requirements.
Do you host the web-viewable 3D model?
Yes — we can provide a shareable hosted link, or supply deliverables for your own hosting where required. Hosting options and duration can be agreed as part of the quote.
Do you need scaffolding or access equipment?
Often not. Our approach is designed to reduce working-at-height and minimise disruption. If limited access would significantly improve coverage, we’ll identify that during planning.
Can you work on active sites?
Yes. We plan around live environments and your site rules, and can work out-of-hours where needed to reduce disruption.
Do you need permissions for drone flights?
We’ll assess the location and manage the operational requirements needed to fly legally and safely. If the site has restrictions, we’ll advise early and plan accordingly.
How do you handle confidentiality and data security?
We treat client data as confidential and can work under NDA where required. Sharing links and deliverables can be restricted to agreed recipients.
