Still working on the Warehouse pieces but I've made some great progress towards completing several buildings. I basically took everything I was able to cast before wearing out the first set of molds and work them up into several buildings. You'll have to excuse the conditions of the grounds as the workmen left the place in a mess in their hurry to get to the pubs on a payday.

I'll be working on the walls and out buildings for each cluster this weekend. I might even get some painting done.
While I will probably have some set pieces for sale occasionally and will be happy to take custom orders one at a time, after putting these together I don't think I'll be doing them on a mass commercial basis. But I have been thinking of making the molds available to interested parties. A very rough cost estimate for the basic set of molds to make the pieces shown would be in the $100 to $200 range. Each mold is good for about 20-30 casts in resin before it starts to warp give you curved wall ends. Casting in plaster as opposed to resin will make the molds last a lot longer. Some decent sanding equipment would also be required.
Many thanks to everyone that has offered their insight and help in this project especially Malamute and Gatetraveller.
