Hi Modelbuilder!
First of all, you are a lucky ....... that you can afford a hobby room, enjopy it!
I would focus on lighting, lots of it and if you have to use lamps I recommend "day light" lamps. I bought a socalled "daylight" light bulp and it is the best (and cheapest) investment in my hobby since years.
If you can afford / manage I'd install lots of TL lighting, then you can work when you want (even when it is dark)
My stash....mmmm....please do not get me started! I have too much to be bothered counting.
