David goes on to describe the method of construction:

Method of Construction

The first step was to make a line drawing of the front elevation of section C just to make sure that my estimated dimensions were on the right lines and that printing would be of the necessary accuracy (see fig. 6).

Next followed the detailed drawing of all the elevations -front, side and platform. Wherever possible, actual door and window surrounds were copied from the photographs and resized in situ (see figs. 7- 23, below).

The process of determining dimensions was carried out from the photographs, and some examples of this are shown in fig. 24, below.

These images were then printed onto A4 sheets of white card. The ink used in inkjet printers appears to be soluble in water and white spirit so each sheet was sprayed with artist’s fixative. This seems to give some protection but care has to be taken to protect the parts from contact with these. I’m also not too sure about the colour permanence of the ink so it may be a good idea to shield models made this way from direct sunlight.
