I disagree about the T1-11 5/8 in GP Siding. That stuff is pretty durable, and with the right water sealant or paintjob, ought to last long enough. It maynot be as long lasting as vinly, but it can take a hit better, vinyl can get holes in it, and be difficult to find a replacement piece.As for the fireplace, it has to be built correctly, to work correctly. If you build the fireplace on the side of the house, you will have the problem, of the chimmney getting cold air in it, and will have smoke blow back in your house. A fireplace should be centered in the middle of the house, so the chimmney can have an insulated barrier, to prevent this common problem. The chimmney needs to be straight vertical from the fireplace bottom, all the way to the top. Yes, a fireplace needs to be cleaned, but I like them better than a wood stove, though I like wood stoves. Price wise, you can get a standard boxwood stove, for about $175.00, not including chimney piping, or reclaimer, but for a larger one your looking at about $500.00-$2,000.00 depending on what kind you get. With a fire place you just have to pay for the block,brick,mortar, and concrete, and a few other things, and do the work. I like the look of a fireplace vs, a woodstove, though the woodstove may be the easy way to go. I don't always do things the easy way, if I believe the harder way is better altogether. Quickrete, for footing will do, but I understand what you mean about one continuous form, poured at one time. I don't know how much a load of concrete poured in a form will cost right now. I agree with you though, about one solid slab form though. If it isn't to expensive, or too much of a hassel, that is the way I will likely go. Notice the slabs left behind in Joplin after that EF5 Tornado ? Might want to consider anchoring the house to those slabs securely, though 200mph winds would likely shear about any house apart. About the strongest winds we get around here would be about 90mph, unless it's a first. 90mph is about the strongest winds I have ever heard of in WV, of course it is the mountain state. We get flooding,and mud slides, and the occassional wind storms, with about 50-70mph winds, with real strong wind storms being 80-90mph winds. These are not everyday conditions though, but tend to come around annually, in the fall, spring, summer, and maybe even in the winter during a blizzard. With the way things are, and the times we live in, freak storms, and natural disasters isn't a big suprise, so prepare for what you believe could happen, if it isn't something like a Alien invasion, though that o'l devil trys anything, and everything he can against God.
