..is more like a house in the trees. The following shows what the tree house looked like prior to all the panelling I put up. It’s powered by a solar panel that I built, with an integrated 12V battery. The controller makes sure the battery does not get overcharged. I built this for my youngest daughter for personal reasons. It now has knotty pine panelling and wall-to-wall carpeting, recessed LED lighting, dutch doors and curtains.
