The first surprise is that the house is not actually hanging from the trees. Mark knew that would be unsafe, especially with a child living inside every day. Instead, he built the main frame on steel posts set into concrete, carefully placing the structure between the oaks without putting the weight on them or damaging their trunks. The height is modest, more of a raised cabin than a risky playground.

This entrance became Lily’s favorite part before the house was even finished. She called it the “bridge home,” because every day after school she crossed from ordinary life into something that felt private and special. Mark kept the deck wide enough for two chairs, a crate of muddy boots, one small pot of herbs, and a place to watch the sky change through the leaves after dinner.
