This acorn-shaped treehouse was featured in the NY Times magazine of winter 2008 (photo by Dina Pugh). It was built by Jay Nelson on museum director Lawrence Rinder’s 40 acres near Ukiah, CA. Nelson, a young San Francisco bay area artist, is described by Rinder as straddling a line “between urbane and rural, between avant-garde and retrograde, between the dissolution of the boundaries between art and life and the careful management of both.” Yep, that’s all in the article. Here’s what’s not: a video of the treehouse being installed.
The General Store just opened up in San Francisco with this little greenhouse in the back yard, built by area artist Jesse Schlesinger. I snagged this photo from Lloyd’s Blog. Lloyd stumbled upon it one day after stopping in a coffee shop next door: “I fall in love with a building now and then, and this was one of those. Proportion, placement, used materials, it all comes together.” Amen brotha.
Mining relics… this is an old engine house in Cornwell. Photographed by Thenenan T. Kig. Via BldgBlog.

By way of Shedworking, I found this Hobbit-inspired East Hampton treehouse featured in Architectural Digest. Great quote from designer Jeanie Stiles: “A tree house should never overpower the tree in which it is built. It should sit lightly in the branches.” I do respect those builders who recognize the tree as a living being.
Next time I’m in BC, I’m going to check out Rod Palm’s house on the West Coast of Vancouver Island. Mr. Palm owns Strawberry Island, and does marine research there. Wish I could find interior photos… this one was found on Flickr.
Artist Kane Cunningham bought this house for a few thousand bucks in order to document it falling off a cliff into the sea, which, according to him, can be at any moment. It is the next house in a series of houses meeting their demise in Scarborough, North Yorkshire. “It’s global recession and global warming encapsulated.” Mr. Cunningham invites letters to be sent to this address (20 Knipe Point), which will eventually cease to exist. Here’s the BBC story.
