Remodeled basements can mean additional living rooms, play rooms for the kids, home offices and a lot more.
One advantage of remodeling a basement is that it's not generally an essential living space, so you can take your time, doing one area at a time. But be aware that, to save money, you'll want to do all of the necessary plumbing and electrical work while walls and floors are unfinished.
Your basement probably houses some of your home's work engines: a boiler, hot water heater, furnace, maybe an extensive network of pipes carrying water or sewage. It's the area that's extremely susceptible to water damage and leakage. Whatever work you do to your basement, you probably will want to include waterproofing.
