Thank you all for your responsre to this post.
Harry, My intention is not to create a kit. I tried once and it turned out to be a very expensive but educational proposition. The cost of creating a kit is very expensive in time creating the masters. Mold and resin cost. The market is limited to the few people who may also want exactly what I made. Sorry but I can not give you a price for the entire front as shown.
My approach is to offer items (parts) I created for my models that could be useful to others in creating a building to their specific size shape and purpose. Take for example the 'bay window' This is a fairly difficult item to scratch build. A modeler using my part can accomplish the task of adding bay windows to multiple kinds and styles of buildings with minimal effort.
The building front pictured is 6-1/4" wide. My search was for a building that would fit in the area I dad to fill which was about 6-1/2" wide. The plans were selected because it called for a 25' avenue front depth or 6-1/4". The street length of the building block was truncated by limiting the houses to 5 mid block ones.
If you notice on twio fo the photos that I had to create a side facing stoop because as you mentioned realestate is limited on a layout. Even in this situation I still have to widen the side walk to make the appearance correct.
Jim, Woodward showed 2 building blocks and one mid block house or appartment house in his book. I got the feeling the drawings were based on New York architecture. Any way all of them were in my imnd suited for a model railroad layout. The finished building would top out at about 16"high . Such a building would allow an elevated train to pass below the roof line nicely. Memories of riding the 3rd ave L when I was a kid.
