You might not be able to have something exactly like Michael Pollan's writing house, but it is worth your time to find something similar to it...
Here are some tips on how to get closer to Michael's recluse paradise:
1. Shut down your mass weapons of distraction.
Phone, email, Facebook, twitter, visitors, TV, web browsing, etc. These elements are designed to attract and control your attention. Unless you have the will power of a Supermonk, shut them off. Give your focus a fighting chance.
2. Find a physical location that has built-in distraction minimizers.
To achieve number one, you might need to do number two. Michael's Writing House works because of the recluse nature of the structure itself. It is physically removed from people, possibly Internet, etc. From the look of it, he pretty much has access to a handful of books, his laptop, a printer and oxygen. When I was in college, this was the fifth floor of the library. Your options are endless if you choose to seek them out: a restaurant, a library, a neighbor/friend's house, your backyard, the hood of your vehicle in the middle of a field, etc.
3. Surround yourself with sights, sounds and smells that inspire YOU.
I don't know, but I would venture to guess that Micheal is inspired by nature, especially since he is a green movement advocate. His Writing House is built of natural material and looks to be in the middle of Sherwood Forrest. These sights, sounds and smells are simply muse fuel. There might even be a certain time of day where he is most prolific. You need to do some self-evaluation and figure out what sights, sounds and smells most inspire you to be creative and/or ultra productive in solo projects. It might be in the middle of a bright, loud, and busy cafe or it could be in your grandma's dark, damp, and quiet basement.
