Just bought a house with a large greenhouse… how do you actually use yours?

I’m in the process of buying a home that comes with a pretty large greenhouse in the backyard (roughly 15x20+), and I’m trying to figure out how people actually use these in real life. The previous owners clearly got a lot of use out of it, but I’ve never had anything close to this before. Up until now, I’ve barely had a backyard, so this is all new territory. For those of you who have larger greenhouses: Are you actively using it year-round, or does it end up being more seasonal? What are you mainly growing? (veggies, herbs, flowers, tropicals, etc.) Has anyone turned part of it into more of a sitting/relaxation space, or is that not really practical? Any “wish I knew this earlier” advice? One other thing I found interesting: there’s a wood-burning stove in the corner, but there’s also a radiator heater installed. Curious how people typically use heating setups like that. Is the stove more of a backup or for specific conditions? We both enjoy gardening and are excited to get into it, just trying to learn from folks who’ve already gone down this path. Appreciate any insight!
