Building a dollhouse is not simply a weekend project. Building one is quite similar to the building of a full size home. There are walls, floors, ceilings, stairways, windows and more. The only real difference is the scale which is very crucial. After all, you want everything to remain in perspective. Building the house itself is usually quite quick. It's the decor that can take a long time to complete...if ever completed. Regardless, beginning with a good workspace is probably the most important aspect.
