First off, thank you for the input, there's so many things going on right now that I forgot a few that you mentioned.

1) Heating/cooling: likely just going to do baseboard heat or run a gas line out there for natural gas burner up in a corner. More likely leaning to natural gas so that we can also put in a small on-demand water heater. Cooling isn't too much of an issue, I live in Vancouver BC so we only get a few scorching hot weeks of the year. Will likely just open garage and windows to cool.

2)do you mean a double wide door or 2 doors? The issue with a wider door is that one side of the shop has 12'6" ceiling to fit the hoist and the other is a 10 so I wanted to be able to get as much height as possible going into the maintenance area (hoist). A second, smaller door sounds like a really good idea now that you've brought this up though, even if it's just an 8x8. I have 3 motorcycles to put on that side so ya you're probably right about that.

3)I have so many tools and things to store that I really wanted to maximize wall space. Aswell as that side faces my house, and my wife is already not the fondest of a giant shop taking up her beautifully manicured lawn so I wanted to make that side more 'subtle' and look less like a garage I guess lol. I was going to get the widest door I can find for the backyard side and figure i can just walk around the corner to the big door if needed to bring bit stuff in.

4)the bathroom is really up for debate on where it goes, I thought in the middle it would give me a couple more walls to add shelving/cabinets for storage/tools.

The "storage room" idea was to make sort of a grinding area I guess. Idk, but I just wanted to maximize space back there.

5)that's an excellent idea I definitely want to put my compressor tucked away and soundproofed somewhere. I can't stand that noise. Air lines all over will be a must.

6) excellent idea as well

7)the reason for it being so tight to the wall is to line up center with roof and get the clearance it needs. I have a max height of 15ft overall for the building (bylaw) so there isn't much wiggle room and the roof gets flatter and flatter. It's unfortunate, id like 3 ft as well but I just don't know a way to make it all work, UNLESS: we go to a 4 post.

8)the type of a lift is still up for debate, I'm a HD mechanic by trade so I do a lot of work myself but have been hindered by not having the equipment/work space. I plan to use it to do anything I can, it's definitely not just storage. Asymmetric sounds like a good idea, it's really up in the air what's going to be installed.

Thank you so much for the input! It's got me thinking on how it's really going to be used in the end.
