Architect David Stirling, who'll be working on the Manchester, Mass., renovation, shows off a Manchester house he designed. Stirling also discusses plans for the project house's master bedroom with homeowner Bruce Leasure. Outside, there's lead-based exterior paint to strip; and trees and shrubs to remove (temporarily) during construction. Then, on “Ask This Old House,” projects include fixing a damaged garden hose. Also: tips for buying plumbing tools are offered; and in the “housecall” segment, landscaper Roger Cook visits a family with a dirty kitchen floor---the result of mud under the children's swing set. Steve Thomas hosts.
