I am sure that Tub Chairs mixed with a bed furniture is the best solution for your normal size dolls house. Personally I believe that this hobby is a little extreme and to expensive to practice. But everyone is entitled to their own strange hobbies. Can I see some picture of your dolls house?
 

You can try making such furniture yourself. There are some nice DIY jobs websites where you can learn how to do it yourself. Hope you find my advice useful. Good luck and have fun!!

 My daughter loved so much the Fargo ND hotel and she requested a doll house with the same living.She collects doll rooms and houses and my husband is building them for her.He's a carpenter and he knows hou to use little pieces of wood and how to recycle materials so we don't have to spend a lot of money on plastic houses.

It's good to see that there still are people preoccupied with this hobby. I remember that in my childhood I had a beautiful doll house with projector lamps and a mini garage. Too bad that the kids these days don't build many doll houses.

You know what's so great about these houses? That you can actually imagine yourself living there, without any worries, like having to cook, going to the bathroom or bugs extermination. I'm not a doll, I consider myself being pretty ugly, that's why I love to create tiny perfect places, it's my getaway from reality sometimes.
