Money and renovation

I feel a need to talk numbers. However, finances are a very personal topic, it’s sort of like talking about the details of your last doctor’s appointment. Yet, without numbers the topic remains vague.
In 2007 I documented the renovation of my house. Prior to that in 2003 the kitchen was done. Both jobs were done by David of Something Different, and I’m quite happy with David’s work and his work ethic. The kitchen cost about $17,000 and the main renovation was around $100K (hello big fat 2nd mortgage), counting the work done before and after with heating and cooling. The house is a little over 1,000 sq feet, not counting the cellar. So those are the numbers.
So when I hear others say that a renovation for a certain house of roughly the same size would be $200K to $300K to renovate, I’m not totally convinced. Not that you can’t spend that much, but it seems you can spend less. People with more building daring have spent less, being their own general contractor, saving $40K, working with the same sq. footage as my house. From my own experience, I know I could have saved some money by cutting out some luxuries. Such as the heated floor in the kitchen, the tile from Expo, the fancy bathroom with the claw foot tub, the separate heating and cooling systems. Of course there are some things I did and didn’t do that would have bumped the price up. I didn’t replace the section 8 windows, they work, the eco-building guy said they were acceptable, I’ll replace them later. I used low VOC paint, which costs more than regular Home Depot paint. On the other hand, some wonderful volunteer helpers and I painted the house, saving on labor.
Labor, that was a majority of my expenses. David bills by labor and materials. If I wanted we could have come up with a single bid price for the whole job but it would have been more. But with David’s way I saw what I was paying for, and man are men expensive, even the unskilled ones.
Lastly, a thing that I think really helped in price was I was renovating the house for me, not some unknown buyer whose tastes and preferences are unknown. I don’t need stainless steel anythings, so I won’t pay top dollar. I prefer Corian to granite, Formica would have been acceptable too. I am okay with used items, like the tub and the radiators. Also okay with the low end barber carpet. I like IKEA, and we hacked them a bit and gave them a non-IKEA look. My tastes were not an unknown factor, so then money could be targeted towards things I actually cared about or whatever David convincingly talked me into, like the heart pine floors.
