Much of the year, the bungalow spreads out-of-doors. At the Berthelot home, four French doors open into the screened porch, which is comfortably furnished for relaxing, eating, and entertaining. In this Northwest Florida climate, the cooler autumn and gloriously floral spring are especially welcoming, but the shady setting, southern architecture, and a ceiling fam lure folks out even on hot summer days and nights.
