I'm considering getting a greenhouse, but I'd like it attached to my home so i can sit in it in the winter. I've really gone back and forth on the idea because much as I'd love a greenhouse, my home is already way too big. Id also want it attached to my home so I could sit in it in the winter easily (I'm near Philadelphia) and it would have to look good with the house. Heavier framed than many of the ones I see on the internet.

I have no idea where to start in the process.

Any thoughts or ideas on it would be appreciated.
