Can anyone offer me some tips for setting up a home studio? I've never had a dedicated room of my own before (at least not one where I'm allowed to do things like drilling into the walls!

I imagine bass traps are going to need to be fairly high up on my list. I'm also thinking of lining one of the longer walls with open shelving to store all my music gear. I'll need to get a desk as well - maybe something like this: https://www.gear4music.com/Recording-an ... tural/2QY9. That's as far as I've got in my thinking up to now.
Any thoughts, recommendations or resources that you could share with me? Any favoured brands, or things I should avoid? I don't have a huge amount of cash at the moment, so I'd like to get something basic working fairly quickly, and maybe look to upgrade gradually in the future.
All thoughts gratefully received. Thank you!
