I am in the planning phase of my shop and greenhouse and construction will start in the next couple of months. I am in central Mississippi in zone 8b.
The actual building will be 24' wide and 48' long. It will have a gabled roof. One gable end will face due south. This will be the greenhouse end. The greenhouse portion will be glazed on the east, south, and west walls with clear poly carbonate panels. The gabled roof of the greenhouse will also be clear. The overall floor space of the greenhouses will be 24' X 16". The North wall that separates the shop from the greenhouse will also be clear to let light into the shop. On this North wall will be a fish tank that is 20' long, 4' feet wide and 4' deep partially sunken into the ground so 2 to 3 feet stick out of the ground. I will install vents and fans to move heat in the spring, summer, and fall.
The shop that attaches to the greenhouse will have the north and west walls sided with solid panels. The east wall will be clear also to let in light. The roof will be insulated metal. The shop will be 24'X32". The overall height of the building will be 10' sides and about a 14' gable.
The greenhouse portion will serve to start seeds in the winter as well as house some citrus trees during our cold months. The trees will be in large containers that can be placed outside in the spring. The fish tank will be for fun (love running water) and to use to water the plants. Rain catchment into IBC's will serve to refill the fish tank as needed. This shop/greenhouse will be in the center of our garden and orchard in our back yard.
Do you guys see any major flaws with this design?
I may should run the metal out a little further so the fish tank is shaded through spring summer and fall.
One idea is to get a piece of 40% greenhouse shade cloth that you can wind up and down to cover the glazed part of the roof and/or the glazed south wall.
Depending on what kind of glazing you use, you may get some "sanding" effects from the shade cloth laying on the glazing and wind, etc. This will not hurt the plants any, but it may look bad if you have super clear rigid glazing.
Multi-purpose shops are an interest of mine, though. I live on a homestead and sheltered shop space has been something absolutely required - same for every homestead I’m acquainted with. I’ve been contemplating a consolidation of three “shop” areas I’ve got on my place: One heated (but too small) where I do my handyman stuff (electrical, bench-carpentry, etc) & some of my woodworking. Another roofed-over, but open-air, where I have building lumber stored and my table saw is located. The third one (roofed-over, open-air) where I’ve got welders, a metal assembly table, vises, grinders, compressor & a sandblaster etc - where I do small-engine equipment work and other mechanical & metal construction or repair work.
In collecting ideas for a new shop, I’ve created a Pinterest board showing shop layouts and photos or video tours - with links to online articles, videos, and forum threads. I’ll mention again that these pertain to mixed shops, not "dream shops" for fancy woodworking or for working on motorcycles or hot rods.

Just thought the board might help you with your planning.

The light entering the roof would only benefit entering the gable end of the shop during the winter sun angle and would cause too much overheating in the summer. I like your decision to let the light in from the east. morning sun is usually desirable most of the year. but evening sun is a killer in the summer. You wil probably wand to plan on a shade for the west side of the greenhouse for the summer. You want your greenhouse to be cooler than outside during the summer for cool loving greens. The fish tank should be a great heat sink to keep it warmer in winter and cooler in summer. Also consider being able to draw cool air from under the ground or building.
Thanks, I see you are in Washington. I lived in Portland when I was a teen. Love that part of the world.
I considered the idea of metal all the way across the greenhouse but was a little unsure of there being enough light. I think you are probably right though. I saw for the first time the other day how someone was using piping under their greenhouse to heat and cool. I will look into it further.
If you try to please everybody, your progress is limited by the noisiest fool. And this tiny ad:
