What's that white stuff on the floor in the background

?
We don't get that here in South Texas!
That's free air conditioning in Minnesota.
XcYZ,
The shelves are brilliant, so brilliant infact, I see some being fabricated in my garage. I really wish i could put into words how much I like those shelves and please take my "copy cat" attempt as a form of flattery.
Before i launch into my attempt i would like to pick your brain for a moment. I see you built them out of 2x6's, awesome, great minds think a like. I am curious as to how you attached them to the wall. Does each 2x6 coming off the wall attach to the studs, or did you drywall, build the shelves and screwed them into the wall? I am curious about the vertical supports going to the roof. Threw the dry wall to each roof truss, or dry wall with a cross 2x4 spanning the roof with the supports fastened to that?
Lastly, how deep are those shelves? I have terrible depth prospection with pictures.
Thank you again for sharing this GENIUS idea,
Scott
Thanks, glad you like it.
The 2x6's extend into the wall and are screwed to the studs. The vertical supports are screwed into the back of the face of the soffit so I could finish it off. There's a 2x4 that runs along the ceiling that's screwed to the bottom of the rafters so the vertical supports would have something to attach to. The vertical supports are spaced around 4 ft apart.
The depth of the soffit is 24". I designed it that way so I could simply cut a 4x8 sheet of plywood in half and not have any waste. I just had to notch out the plywood where the vertical 2x4 supports were. The height of the soffit opening is also 24". That was also based on being able to take a sheet of 5/8" MDF, cutting it in half and having 2 sliding doors ready to go. Well, that was the plan anyways. After adding the roller tracks and the 1x4 nailer for installing the trim to hide the tracks, the sliding soffit doors are about 22".
Now I have no plans on putting an engine block or transmission up there, but it's fantastic for stuff that I want to keep but only need on occasion. Right now, I have all my extra electrical supplies up there, along with a lot of original Camaro interior parts like the dash, window regulators, door panels, etc. Just tons of random stuff. The soffit also worked awesome for mounting my speakers. They're just laying on their side on the shelf. I just cut the openings in the sliding doors to match the speakers, then re-used the speaker grills to cover up the holes. To mount the grills, I just drilled 4 holes in each door that align to the mounting pegs of the grills and pressed them in. Works great and looks decent I think.
Attached is a pic of a grey plate that I used for a test. It matches the paint on the service door and window trim perfectly, so I ordered up everything I need for replacing all the receptacles, switches and covers in the same grey. Should look good I think. You can also see the last thing I need to do - paint and install the service door trim.
I should also note that I installed the recessed lights 18" out from the wall and NOT centered at 12". You can see that in the attached pic as well. I knew I'd be installing 12" deep wall cabinets, so I split the difference from where the face of the wall cabinets would be to the face of the soffit.
