2D Orthophoto image of a 3D building


With the latest developments in 3D modelling software we are able to use the photogrammetric processing of digital images to generate 3D spatial data. We can create a fully rendered and incredibly lifelike 3D model that is dimensionally accurate. Crucially, the various stages of the software process also enable the information to be output in useable formats. Such as a point cloud, which is Revit compatible, and 2D rectified Orthophotographs.

One of the many benefits is being able to accurately draw irregular and unusual shaped buildings or structures. It is increasingly considered to be an efficient way to record within the conservation and historic sector. “BIM is arguably more important in the case of significant historic assets, where any change in the historic fabric must be carefully considered and justified.” Historic England

One example seen here is of The Market Cross in Barnard Castle, a building central to the town.


  • What is photogrammetry?

Photogrammetry is a relatively new technique for 3D scanning. You can capture large objects, like buildings, bridges and other structures. It is the technology of obtaining reliable information about physical objects through the process of recording, measuring and interpreting photographic images.

  • Why is a 3D model useful in the conservation of historic properties?

Recording buildings and structures has up until recently been achieved through photography and 2D technical drawings. 3D models offer a new technology that give a life like representation of what is actually there which provides an accurate recording of the asset.

  • If I get a 3D model made of my property- how do I view it?

Using the online platform Sketchfab we are able to upload the 3D model, password protected, and share with clients which makes it accessible to all.
