i just had my dream come true 2 months ago..i had a 35x60 arch us building 18' tall built.it was costly but its a very very secure bldg..with a 15x20 foot forging (crushed #10 stone dust)area as my friend and bs mentor doug merkel did to his shop..his is a huge post and beam..mine is smaller and arched..i had it with 6' straight walls so i did not loose space on low arched area as some are..i should of gone 8' oh well hind sight lol..
i am building a series of sepperate rooms on both side of the big doors and will add on a 2nd floor above thos rooms for a extra 1,000 sgft for roughly 3,000 sqft...the seperate rooms are for different arts and crafts not wanting to cross contamaneteeach other,,one for fine finishing like knives and jewelry...others pottery,leather..and a grinding room with a metal dust collector and spark arrestor...the open area will have wood working machines that ill move about freeing up space as i need it.
the shop has 4" of concrete with 3x the rebar as the contractor planed on useing..to me ill always over build..it pays off later.
with the bldg up and 7 power circuts on for now the hard part is deciedng the size of the rooms and where to put in power and eqt so its a very efficent plan that later i do NOT have to re build urrr lol...its going to be a work in process as i go...but now all my eqt is under one roof.
