Hello! I am a young freelance software engineer who moved out to Raleigh about a year ago to live in the country but have close access to the city. I own about 10 acres of land and built myself a treehouse in the middle of my "forest." What I'm offering is a 2nd treehouse close to mine for someone who is looking for a more natural / off the grid environment. This is ideal for "work from home" types. Here are the details:
Awesomeness Hand-Crafted:
- Very small and cozy. Essentially a 600sq ft apartment
- Composting toilet
- Solar system for laptop charging (panels plus deep cell batteries)
- Small propane stove for cooking
- .25 mile walk to the driveway (where I have my car)
- Sleeping bag + electric spaceheater to stay warm in the winter
- Small fan for staying cool in the summer (although the heat didn't bother me too much this year)
- About 20' off the ground (too high up for the annoying bugs)
- Rope ladder to get up and down
- Rainwater catchment system w/ water purifier
- Dumbwaiter for getting stuff into / out of the treehouse
- WiFi system installed (yes, internets in the forest)
- Shared workshop / toolshed that is on the ground
The Good:
- Off the grid. No utility bills.
- Wake up with the astonishing beauty of nature
- Occasionally see some forest critters
- Fresh air
- It's a treehouse!
The Bad:
- Getting cold some nights (that's when I got the space heater)
- Climbing up and down the ladder multiple times in a day can be a little annoying
- Too many days of overcast and I ran out of electricity. I installed more solar panels so this shouldn't be a problem
- If you have trouble with the idea of composting your excrements this isn't the lifestyle for you
- Trying to get big things up 20' is difficult by yourself (like a mattress.. necessary but ugh)
- No refrigeration! This isn't that bad when you adjust your diet (more in a separate email if you want to know more)
- Laundry must be hauled into town or use a hand-washing system (which I do for everything but my bluejeans). This is particularly important in the winter!
From the picture, it looks spherical, and probably 2 levels. I really don't think it's 600 sq ft, but it's very interesting.
