Recently, my wife and I bought our first house. We are still moving in. Time to stop living in an 80-year-old rental townhouse in a historic area under a canopy of old growth trees. The new place has less character, but at least we can afford to 'own' it! The house is a 'transitional ranch' (whatever that means); it is a ranch with cathedral ceilings over the kitchen and living/dining rooms (and a large attic, not currently equipped for storage, over the rest of the ground floor). It has 3 bedrooms and 2 full baths, but the 'extra' bedrooms are small, only large enough for young children. One of my criteria for the house was that there be a room that could be used as a dedicated home theater, even if it were a small one. About 40% of the basement is finished, the useful part of the finished area is a 17x18 (approximate) room with a walk-out basement (the house is on an incline, which works wonders for drainage; the basement stayed dry even under recent flood conditions). I'd like to use this room for home theater. There are back-up plans; another 14x19 area in the unfinished portion could be made into a room; or in a pinch we could do front-projection in the living room. But I'd rather use this room in the finished area of the basement for home theater if at all possible! The rub is a support post in the dead center of the room. If I could get rid of it, and place a couple of support posts off to the side the room would be pretty good for this purpose! The post supports a steel I-beam, one of two in the house. The other beam is in the unfinished half, and has two support posts of its own. There are likely two other posts in the finished half, inside of existing walls. I'm going to use a metal detector to verify this. I know that I have to have a licensed structural engineer assess the situation and make up a plan that I can use to get a permit (assuming that there is a cost-effective solution). But if anyone has any past experiences to share which may prove useful (things to watch out for as I proceed), I'd be much appreciative if you could share them!
