Here's a favourite website I go to, to dream of not just working from home, but having an "office" to work from at home. Shedworking
Sounds a little primitive, but you should see some of the things people come up with, primitive is the furthest from what it is, some of them are downright extravagant.
Personally I would situate mine out past the pasture near the woods and brook.


And if I can't have a yurt or a shed, I would like a treehouse.

A tree house.
A free house.
A secret you and me house.
A high up in the leafy branches.
A happy as can be house.
A street house.
A neat house.
A be sure to wipe your feet house,
is not the kind of house for me.
Let's go and live in a treehouse.
