IIC Technologies of Harrogate, specialise in 3D modelling of buildings like Mingary.
The two Davids are back because they weren't satisfied with the quality of the first survey they did - the outside of the building was fine, but they needed to re-do the interior. It's a reflection on the project's attention to detail.
Many thanks to David Crawford and David McCreadie for their patience in describing what they were doing.
The Mingary Castle restoration blog was written by Jon Haylett, who lives in the local village of Kilchoan. Now that restoration is almost complete Holly and Chris Bull will take over to report on bringing the Castle back to life.
