The Fairfax (Virginia) County Times has a regular column by Bruce Wentworth, architect and principal at Wentworth Studio in Chevy Chase, where readers' questions about their own homes and remodel issues and architecture in general are answered in detail. From the September 12 column:
I own a classic 1,200-square-foot bungalow built in the mid-1920s and I want to remodel my rear-of-the-house kitchen as well as build a two-story rear addition that will include a new family room below and a master suite above. What are some architectural considerations that will help ensure the added space will appear to be a part of the whole ... not merely tacked on? - A.L., Vienna
