I work from home and the last lab I had was spare space at the end of the hallway, maybe 2m^2 maximum. It was packed to the gills, and much of the equipment I had that was rarely used ended up in cupboards in the spare room.
I moved a year or so ago, and decided as part of that I'd get enough space for a proper office. That space is 7m^2, and within six months the space was full again.
The benefit of working from home are many, one of which is the view from the window and the balcony, but realistically I maybe look out of the window once a day if at all, and the balcony is used once per month if that. The balcony at the last place had an awesome view over the Thames too, I just didn't use it very much, and when I did it was usually with a pint of gin and tonic in hand.
