I'm 'of that age' where I have a large-ish house, and hence a large, well equipped study. I don't much like my work office. It's on the top end of 'good': spacious, well equipped, light, modern, free snacks, etc. But... and it's a big but, it's open plan. And noisy. With people eating at their desks, talking, interrupting you and so on.
But I still miss it. The last nine months has taught me that whilst I work fine from home, I thought I'd be completely happy like that, but I'm not. And I'm surprised by that. I want to go back to the office, but not for 9-5, 5 days a week. Once a week will be fine.
