This Old House

In the basement, host Kevin O'Connor finds plumbing and heating expert Richard Trethewey finishing up the installation of the floor-warming radiant heat that will be in the slab under the new family room. A concrete pump truck arrives to pour all of the concrete on the basement level, including the footings for the new deck, and a team of concrete finishers works to create a smooth and level new basement floor. In a tile showroom at the Boston Design Center, Kevin and homeowner Allison Sharma meet interior designer Melissa Gulley to begin making aesthetic decisions for the entire project. Melissa gets a feel for Allison's style by looking at images she loves, pulled from books and magazines. Back at the house, general contractor Tom Silva is busy installing the new energy efficient, vinyl clad casement windows in what was formerly one of the darkest corners of the house. He cuts in new window and wall openings to reveal the spectacular views of the Charles River for the first time in that corner.
