Hi John, and welcome to the forum. I took the liberty of copying the intro from your profile page and pasting it below. I hope you don't mind. It's an interesting story, to say the least!
I am a noob to dollhouse building. I have two granddaughters (6 and 1) who need, or will need, dollhouses built by their Papa. I am a railroad modeler in 1:20.3 scale, and have scratch built several models in that scale, including cutting my own scale lumber. I have most of the needed tools and some of the required expertise, so I am not intimidated by the complexity of the dollhouse kits I now have. Speaking of which, they are a Dura-Craft Newberg, a Greenleaf Pierce, and a Greenleaf Beacon Hill. I am currently renovating a dollhouse that my father built for my grand nieces about 20 years ago. I believe it's a Dura-Craft, but I haven't identified the model yet. My plans for the Newberg are to make it a reasonable facsimile of Carl and Ellie's house from UP. It's close enough that paint would be enough for many people, but I plan to cut the foundation in half heightwise, new windows and front door (including all the locks), a chimney, and of course balloons! I haven't decided if I want to tackle altering the roof to more closely resemble the UP house. I'll probably mock something up to determine the feasibility of that undertaking. Oh, and I need to find reasonable models of Carl, Russell, Kevin, and Dug.
