Five years ago I gutted our entire 2nd floor (small 100+ year old house) and doubled the size. So it went from 12 x 26 to 24 x 26. So I may have slightly misspoken on the size of my build, I completely gutted the existing second floor to the exterior wall and then doubled the size with new construction. I spent our entire tax return on the structural lumber for the addition and deck so the cost was under $5800, this does not include any 2x4’s. 2x4’s were all free off craigslist plus I had a bunch in my lumber pile. All sheathing was purchased new but I don’t remember what I paid exactly, maybe $700 (10 sheets ¾ OSB tg @ $20 = $200 and about 40 sheets ½” OSB @ $12.50 = $500). All the drywall for the project cost me 72 cents a sheet at Home Depot. They were selling off an entire stack that somebody sheared a corner off. So with mud and a couple rolls of tape I was under $50. Electrical, all free left over from various jobs I have done over the years and I still have lots left in my store room. I bought some of the PVC sanitary plumbing and used a lot of what I had left from other jobs as well so I might have spent $150. PEX was mostly free as well because I also have tons of that in my store room. I bought all the insulation (in new condition) from two separate guys on craigslist as well as a window or two and the cost was really negligible, maybe $300. Windows and Plumbing fixtures were all bought at a 2nd’s supply house here in town for literally pennies on the dollar. For example a new vinyl window costs me between $75 and $100 depending on the size. I purchased a new steel tub, toilet and 36” vanity top from this same place for under $300. The tile in my bathroom was all on closeout for 50 cents a square foot. I was given two windows for helping a friend build a shed. The roofing cost me $27 a bundle for the shingles, so that plus the miscellaneous roofing materials was all under $1100. Siding cost me around $220 for 1 ½ cases as I was able to reuse a lot of the existing siding. One exterior French door cost me $420 at home depot. Carpet was less than $100 per room as I used remnants bought at a different discount/seconds type store.
That alone adds up to about $8750, the rest of the hardware, trim and paint came in under the $10,000 mark. I didn’t include the cost of permits because that came out of a different pot/budget(purchased the year before) but if I recall they were around the $600 dollar mark. I am sure of the total amount only because before we began the wife and I made a deal not to go over that mark because we ultimately are going to bulldoze the entire house and start from scratch.
Here are a few pictures but I didn't have room to include the walk in closet and all of the daughter’s room... (Oh, I waterproofed the underside of the deck the following year so that cost wasn't considered either...)
Thanks!
