Foundation questions, options
I'm trying to educate myself a bit about foundations ( and 100 other things) before we start talking with General Contractors.
We are building a 1500 sq ft cottage/cabin in a rural, wooded and rocky area. It will be a vacation home. We are in a cold climate (hot summers, cold winters). We don't want or need a basement. We have two potential building sites, one sloped facing south, one flat facing east. I prefer the south facing sloped lot as it is more accessible from the road/driveway, and because we may be able to take advantage of passive solar heating.
What foundation options are there for sloped sites? There isn't a whole lot of soil on either site before you hit rock. I had assumed piers might be the best bet, but I'd appreciate your thoughts.
