While its magic and whimsy come from its design, the treehouse’s warmth radiates from the wood: repurposed live oak, juniper, red cedar and wallaba shingles.

Wallaba, wol′a-ba, n. a Guiana tree with winged leaves and streaked reddish wood.

Here the finest green-heart grows, and wallaba, purple-heart, siloabali, sawari, buletre, tauronira, and mora, are met with in vast abundance, far and near, towering up in majestic grandeur, straight as pillars sixty or seventy feet high, without a knot, or branch.

Behold that newly fallen wallaba! 

The second size, all golden green on the back, must be looked for in the wallaba forest.
