You can buy a house for the size and not worry about what period it is. This way you can decorate it as you please in the style you wish. Choose Victorian, Georgian, Tudor or Modern.
The majority of doll houses come in kits and this is probably the most popular way to get started. There are many kits to choose from so choose the design you like and set about adding your own style and touch to the house.
Your local hobby store will be able to help you pick the right house for your price and design. Many hobby stores can even build the house for you. The cost will vary depending on how much work you want the store to do. A hobby master can build it as just the walls or even light and wallpaper it.
Ready built houses will come built with the wallpaper done in each of the rooms and are a bit more expensive. The good part of it is there is no work to be done unless you want to light the house. Here is where your local hobby store can work with you and help you pick out your furniture, etc.
The furniture is a matter of taste. How much do you want to furnish it and how elaborate you get. From grand pianos to the silverware on your table. From dolls to outdoor furnishings.
