Going on location is easy. Getting permission shouldn’t be hard. Traveling back in time to a point it hadn’t yet burned… may require more effort.
The amount of detail makes me think this would be very difficult to model using a photogrammetry-based approach. With enough high-quality, high-resolution images, it might be within the “theoretically possible” range, but I know it’s definitely beyond my capabilities.
I’ve personally had some limited success with photogrammetry and generating models, but only at larger scales with less detail. I’ve had very, very limited experience with 3D sculpting – I have the hardware and software to get started, but so far, not the time. An experienced modeler can certainly recreate the door, but I pale to think about the number of hours of work involved to get all that detail.
