I got a lot of inspiration for my own enclosure through browsing forums like this, so I wanted to share what I came up with in case it helps with your own design. It is always a work in progress of course but let me know what you think or if you have any questions!

*I don’t have a dedicated workshop but have about half of a garage that I utilize for projects.
*I needed something that would be easily moveable should I want to rearrange anything.
*I have kids who are outside all the time and I live in a residential area so I needed something that was very quiet.
*Since the garage is also used for toys, camping, bikes, etc. I needed it to be reasonably dust-free.
*I wanted a functional, budget-conscious option.
*Since plywood is currently $20-30 a sheet and doesn’t really provide much sound attenuation I knew I wanted to use drywall in some manner (only about $8 a sheet) and it provides much better sound absorption.
*Additionally, from adding cellulose insulation to my attic a few years ago, I knew it was fairly cheap (about $8 a bale) and provides excellent sound damping.
*So I opted for a design that reflects a standard interior wall with 2x4 studs, drywall on each side, and the wall cavity filled with cellulose insulation.
*To prevent the cellulose from settling down to the bottom of the cavity, I just made some cardboard baffles every few feet to keep the cellulose in place.
*I used recycled 2x4s from an old bedframe and leftover wood I had in the garage
*8 sheets of drywall
*2 bales of cellulose insulation
*Two sheets of 24"x24" 1/4 thick polycarbonate for the windows: https://www.amazon.com/gp/product/B006JP5MXK/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
*Eight 25-lb magnet door catches to keep the doors shut
*I already had the door handles lying around
*Eight 3" hingles that I found in the Ace Hardware clearance bin for 99-cents each
*Plywood for the Shapeoko shelf base (already had laying around)
*2.5" flex hose (10’ length) for dust collection: https://www.amazon.com/gp/product/B01M35BE8D/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

*LED lights (I already had extras from my microgreens set-up) but they are affordable, easily linkable and simple to use: https://www.amazon.com/gp/product/B07XQDP5X9/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
*4" heavy-duty casters: https://www.amazon.com/gp/product/B0824S6255/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

*I want to add some weather stripping to close up the door gaps to further dampen the sound (although it already has excellent attenuation.)
*I have a smaller shop vac that I plan to swap out. The one that is in-use now gets too hot and is honestly louder than the Shapeoko. I will also shorten the shop vac hose in the final set-up.
