...it's my mother's! It was built by Frodingham Dolls Houses (no longer in business) several years ago. It's a front opening house, but there are no hinges. The front walls and roofs fit together using slots and inside beams to hold everything in place.
The garden to the right is still in progress. Eventually, they will all be "planted" in one flowerbed, so that they can be easily removed to access the house.
Here's a closer view of the front door. The lantern on the left is the one I made.
