Congrats on the house - looks like it must be a beautiful home. Wowza - that IS quite a statement piece, but I'm not even sure it goes in the house as it currently stands. Seems very ornate and traditional for the sleek/modern fireplace insert. There seems to be a market for everything, you just have to find it. Craigslist. local auction houses maybe - but only if it's a real material and not some kind of plaster or foam-type imitation of stone or wood. I don't know what it actually is, but if that is real stone it's going to be crazy heavy and you'll need a whole crew of people to cart it out; and getting it out in one piece/without chipping it to sell to an interested party might be a challenge. If it's real wood there has got to be someone that would be interested in it. Do you know if the wood floors run under the columns? It looks like they should from the picture, and hopefully they do and they were stained the same color before that piece went in, otherwise you're going to have to deal with filling in/replacing/staining to match.
