I do all my own work from start to finish..but did have a guy run out and put up 27' gutters because I didn't want to mess with it.I do concrete(a friend helped me pour it in exchange for helping him hour for hour).I had it all formed up.
I rented a local boat storage shed two miles up the road and packed everything from here in town 100 miles away because the local stores charge an additional ungodly amount for the same thing.
I stacked it in order in the shed as I would need it;precut as much as I could at home so I wouldn't need a generator running more than it should or all the time.
My friend help me stand up the preformed first floor walls..after that I was on my own,even carrying the trusses up to the second floor,standing them by myself and carrying doing all the sheeting(6 in 12..set it down and it slides off and on the ground!
I do all the electrical myself,plumbing,insulation,sheetrock,tsping,& texture,paint,trim,built the cabinet doors from the black oak LOG(dried 10-12 years before building them,inlaid bulletwood diamonds)
carpet,pergo,tile,low voltage,siding,roofing..whatever..it's all MY fault!
The cottage..is an experiment..to see how cheap I could make something.it was built out of two free sheds off craigslist,free windows,free trusses,paneling was out of a mobile home/craigs,insulation/craigs, was $50 for enough for the entire thing + lots of extra ,pergo was leftover from the house,cabinets were $25 from a garage sale,paid about 1/2 price for all the plywood flooring and roof & wall sheeting,electrical stuff leftover from the house,insdie trim and roofing I paid the full amount for.I probably have about $500-1000 into the entire project(with all the extras I have yet)..not bad considering what it is.It's wired 110 volts with a panel(with a plug)..just plug it in... with a couple circuits and another 110 for a water heater someday.I haven't put any plumbing in it yet but have everything to do so for a small barsink,vanity sink,toilet,small shower(a small future wall/door separates the bathroom from the rest)...I have it in the trailer(all converted to house water,septic/toilet,it's own hotwater tank..) so really don't need it in the cottage...yet.
I could convert it pretty easy to off the grid..throw it on a trailer,and move it easy.solar water/power on the 12/12 roof or alongside.I might have to split the roof from the main shed body to move it..but that's do-able...water..have a creek on the property but 2-8" Crescent Water District lines run across my property,hard to deny me access to water out of 600' deep Lake Crescent...
I don't mind a grid for comfort and convenience if it's there...I might have to add an addition for putting in a wood stove though..but a small heater should heat it no problem.It's packed with insulation!
