Former Canadian software developer and current carpenter Joel Allen built a unique egg-shaped tree house, The HemLoft. It is located in the woods near Whistler, British Columbia. The exact location of the house is a secret though, because Allen built it on Crown lands - government property - without permission. Allen had to hand-carry all of the materials out to the site and carry the construction waste back out. The HemLoft is a treehouse in the truest sense: the entire weight of the egg-shaped structure is supported by the tree around which it is built. Allen's complete story of the HemLoft, as it's known, is epic and far too long to encapsulate here. But if you can carve the time out of your day it's a worthwhile multi-part read, with photos of the creating process.
