If you’re planning on renovating, but have a sentimental attachment to your old windows and doors, a treehouse or backyard fort is an excellent way of putting them to good use. We’ve gathered some of our favourite treehouses off of Pinterest that feature old looking or repurposed windows and doors. Ready for a trip down memory lane?
