It's a lot nicer than what I intended when I started to build it. Was originally going to do a large run-in, then a quick cheap pole building, then... well, now I have this with a full poured foundation, insulated slab, and stick framed. Plumbing roughed under the slab. And I'm happy!
I think its the curse/blessing of any trade or profession. I design and build things for a living and just can't get past the mental harassment I would have given myself with anything less. Took me longer to build as I saved up money as I went and looked for good materials deals (the windows are Pella's top of the line simulated divided lite - my rep ordered them wrong for another job, got them for the cost of vinyl windows). Even the little run-in woodshed I have at the other end of the property has rafter/plate ties and synthetic roof underlayment - even though I built it out of salvaged deck boards.
Next up hopefully this year will be electric. With any luck insulation and wallboard will follow.
