A favorite spot for both kids and adults to play – and a favorite HLTF project – this custom treehouse in the countryside of Chester County, PA, boasts 8×8 oak timbers attached by lag and through bolts, which will not affect tree growth or harm the trees’ structural integrity. The timbers form a near-circular “foundation” platform spanning three trees at the center of the house. A sleeping loft and rooftop dormer offer stunning views. Much of the wood for the handrails and balusters was collected from the property and hand-crafted on site. The remaining oak was sourced locally.
