Set at the edge of a clear, deep lake just north of Birmingham, the unassuming home of designer Richard Tubb and his partner, Danny Weaver, rises like a tree house from the shore. In the evenings, it glows like a lantern, becoming a beacon of sorts for boaters on Smith Lake.
Originally, their home was a 1970s barnlike cabin defined by a high-pitched, gambrel roof. After transforming its plain interior from shack to chic, Richard and Danny began to consider upping the cottage's square footage. For help, they invited architect and friend Jeff Dungan to join them for a weekend at the lake. Within hours, a plan for a new addition was scribbled onto a cocktail napkin and a boxy, airy, one-room structure began to take form.
