@jerry We worked with an architect to lay down our requirements and they helped us by designing a property that has home designed for aging in place & caters for both my hobby ( WWing ) and my wife's hobby ( gardening ). as for your orchids, have you thought of leanto greenhouse? https://www.bcgreenhouses.com/greenhouses/cross-country/home-attached-greenhouses/
We are seriously looking at their meridian series. can't use their leanto ones because south side of home is going to be walkout.
