The buildings where made using molds from Hirst Arts and cast with Dental Stone. I can't recommend the molds enough as the detail is beautiful and its like building with legos. My only limitation with them so far is my imagination but thankfully Mr Hirst has some amazing examples on his website that really get the brain juices flowing.
This first picture is of all but 1 of the Hirst Arts molds I currently have and I used all of them to make the following buildings.
Here is all my terrain so far. My first few ruins and lots of scatter terrain to really give it a clogged feeling
The next three are a raised platform and statue. The Statue is a resin Mother Marry that I painted to look like warn marble. The platform can go anywhere and will also be used in the temp I'm working on. The Temple of the Weeping Mother
This was the first building I made using the molds. Its mounted on thin card stock and the second floor is made from hobby sticks.
I wanted to get multiple use out of my next building so I made it splitable. When the two halves are together its just a one story building with no roof. Or I can slide them apart and have to separate ruin half houses.
I put accent pices around the outside to make it a bit more fancy.
One half has a removable door while the other half is left to look old and broken.
