I have found an entire community of builders online. Some make this a complete obsession. The following pictures are from one of these. This is the dollhouse I am building, but with probably at least a couple of thousand dollars invested in external trim, trees, gazebo, lights for the porch and inside, etc.
Needless to say, this is not a dollhouse for someone's grandchild. It is a serious collector's house.
Mine will be quite simple compared to this one and sans lights, external plants/shrubs etc.
Mine is to be a dollhouse to be played with by a young girl.
I did find these pics astounding. I cannot imagine the hours involved...however, having checked prices online for lights, wallpaper, and the fancy furniture inside one of these I can imagine the deep pockets needed to complete it.
