Work on the Los Angeles project wraps up with the finishing touches both outside and in. Plaster specialist Alfonso Garcia replicates the original "cake frosting" plaster detail on the walls, while plumbing and heating contractor Eric Downs shows host Kevin O'Connor the new bathroom fan system that not only takes stale air out, but also brings fresh air in through a damper in the basement. Homeowner Kurt Albrecht gets a look at the new HVAC system that will also clean the air, while landscape designer Melanie Williams shows off the finished landscape and the irrigation system that will keep the plants healthy year round. Inside, interior designer Rachel Horn and her team from San Miguel de Allende, Mexico, show master carpenter Norm Abram how they've used a mix of antiques, reproductions and upholstery to create inviting spaces that are appropriate for a Spanish colonial revival. Homeowner Mary Blee introduces Kevin to her new son, who's arrived just in time to enjoy the renovated house. After a look at the master suite and the new kitchen, the family gathers on the back terrace to congratulate general contractor Steve Pallrand and site supervisor Angel Leon on a job well done.
