From that site I was able to construct "skins" for the houses. A month or so ago I finally started applying the "skins." This is a report of the progress as of about a week ago.
And here is a second building (on left) being clad in its skin. I cut and moved the wall pieces higher towards the divide between the lower building part and the roof part which, I think, makes the buildings look better. The piece I trimmed off the top was then glued along the bottom. This second building and a third similarly clad are being mounted on a piece of foam-core to serve as a small set of apartment buildings for my town. They will have walled back yards with a brick patio and some flower beds.
The second and third buildings now have their complete "skins" applied. I still have a fourth one to do which will hopefully happen later this week. Another progress report will be forthcoming.
