This is a dollhouse my parents built for me as a gift when I was a child. I've done some online research and it looks like the Beacon Hill dollhouse. My parents would've purchased it in the early 1980's. As you can see in the pictures, my parents took a few design liberties when constructing it by giving it larger bay windows and other touches. I also have furniture (not pictured) for every room in the house along with dollhouse figures (a 1970's styled family). I have the piece of the front door staircase and any other trim pieces which may have come off. They are stored with the dollhouse furniture. Apart from cleaning it up, and affixing the 3 details, the dollhouse is in excellent condition.
