Drew and Jen Tarara bought their early-1990s suburban house because of the large rooms and finished basement. As roomy as the house is, the place is missing a mudroom, so the plan is to close off the entryway from the front door and tear down the wall from the laundry room to the hallway to open the space up and expand it out. Since the mudroom has become the workhorse of the American home, these homeowners are hoping that future buyers will see the benefit, too, and the hard work will pay off now - and later.
