Ranchito Cascabel, also known as Timmyland, is Tim Sullivan's folk-art fantasy just north of San Miguel de Allende, Mexico. Inspired by the work of Antoni Gaudí in Barcelona, Spain, Sullivan turned what had been a sleeping porch and storage room into a rambling, otherworldly folly.
before you take on building your project, start by sculpting yourself a model. You can use clay soil or purchase modelling clay...it doesn't matter. Your model will represent the thick walls of whatever system you are actually building with. Make sure your model represents some sort of scale...like 1/4" for each foot of the building.
