You should know that there are several scales for miniatures but only one which is very popular. This is the most popular and the most common in most shops. This means that by choosing this scale you will always be able to find lots of little goodies which will fit in your house. The next thing you need to decide on is a budget for your project. Don't feel pressured to do everything at once.
Many miniaturists enjoy doing little bits at a time.
There is a wide variety of styles, sizes and qualities to chose from within that spectrum and it can all seem overwhelming at times. The answers to the next few questions should help you decide on a budget. A small budget house is fine for a young girls first playhouse while many adult collectors prefer the larger, better quality houses. If the house is to be a family project then you might want to get a larger house that everyone can work on. If a young boy is interested in miniatures you might consider a Firehouse, auto garage, Log Cabin or train depot.
