15x6 - Love It or List It

William and Ashley bought their cozy, 1950s home in a prime neighborhood when their family was much smaller, but their three growing sons are testing the limitations of the house. The kitchen is dated and cut off, and two of the boys share a bedroom. Ashley admits that their house is small but believes they can add square footage to increase function and flow. She's ready to have Hilary Farr work her design magic, but William wants David Visentin to show them houses that will convince Ashley to move.
