You can certainly convert your home from a 2-story into a single level home. My question for you is why you would want to do this? We have a number of aging or handicap clients who remodel to make life in their home easier and more functional. For example, some may opt to have the master bedroom, laundry room, a living area and kitchen all on the same level. This means they won't have to climb stairs so often. They still retain the square footage of the home, but now they are able to live mostly on one level. For ideas to make this happen for your home if you are in the Maryland or DC areas, please visit http://www.tabordesignbuild.com. I will also revist this post to see if you gave additional details I can respond to.
