re: So I'm building a workshop, what else should I put in it?

honestly with 15' wide he needs a leanto to store the mower and golf cart.


2 ft bench
3 ft walk/work space
4 ft island
3 ft walk space
2 ft storage rack on other wall

he only has 1 ft left.


15 ft is tight

Your table saw will need 10' of space in front, at least (minimum) 8' in back and 6' wide (4' on one side of the blade and 2' on the other). If you build a4'x8' table on the back side of your saw it can double as drop and work/assembly table.

On the other wall, you'll need a minimum of 8' on one side of your mitre saw and 12' on the other. You can build one long table on the saw side and incorporate a router table if you want.

That's the top of your table. Your saw should be in the gap mounted flush. Be sure to leave enough room for the slide on your saw from the wall.

All your plugs should be 40" from the floor so they are over your tables and minimum 48" apart.

Shelves, shelves, shelves

Clamps, clamps, clamps

Invest in a bolt/screw/nail bin.

220 service at either end and one somewhere for a an AC unit. 220 Window unit will keep it plenty comfortable in a shop that size if you insulate it (spray foam

Lay out the floor before you decide on door and window placement.

These are all things I messed up on the first time and corrected the second time.

I built a 40 x 60 here's what I did for the lay out.
Vaulted trusses so I would have plenty over head room.

I had sky lights installed so no need for lights to be on during the day time, but they do let in a lot of heat. I need to install a fan and ventilation in the ceiling.

20 x 24 office with 10' over head storage all the way down one side 40'long not counting the office. The top of the office has 3/4 plywood flooring for a second floor of storage. A separate 10 x 10 space for my trapping room. I divided my office up with a bathroom, reloading area, hunting and fishing area and a general work bench.

One front 10' roller door and one on the side wall in the back 8'. This has came in real handy.

20' lean to down the whole length of the building. I wish I had gone 30'.

I set up an area for cleaning fish and animals with a floor drain. I used pressure treated plywood for the occasional water spray. I put a 5" x 6" beam to be able to hang deer from. I can back right up to it through that 8' roll up door.

Electrical

Ran 200amp feed under ground and put in 200amp break panel. I have welding machines, air compressor and a water heater on 220. I put in a lot of plugs and lights. I put 4 plugs outside.

Plumbing

I ran floor drains for toilet and to wash down floor. I put water outlets in the front and back. I will have 2 sinks installed for fish cleaning and such.

Compressed air

I ordered the kits from Northern tools that uses the plug in fittings and tubing. I just finished installing it today. It works great but be sure to order extra T's, 90's and threaded fittings.

I still have a long ways to go to finish mine. Doing it yourself is very time consuming. Just installing the 120 plug in took me almost 2 days. I have ran around 1,300' of electrical wire so far.
