Door and window overview and plan
The door and two windows were identical in make although the door was about 5/8" (15mm) narrower than the windows as it had to have clearance to open and close.
The door/windows were constructed out of 1 1/2" x 2 5/8" (65mm x 39mm) cedar for the side stiles (the vertical sides members) and the top rails (the horizontal top member).
The bottom rails were made out 1½" x 7¼" (180mm x 39m) cedar joined together to make the required width.
The muntin bars (grilles, grid) were of 3/4" x 3/4" (18mm x18mm) cedar.
There were two grids of muntins per door/window. A sheet of acrylic was sandwiched between the two grids.
Note: If you are making this door or window, use the measurements as a guide only, as the wood that you use may differ in size along with other inconsistencies.
Check all measurements on site.
The imperial measurements given are not an exact match for the metric measurements. Use one or the other but don't mix and match. For the most part 1" is translated into 25mm for rounding off purposes. In other words, a telephone box made using the imperial dimensions will be slightly bigger that if you use the metric dimensions. About 1.6% or so. Not really worth worrying about.
