This 1936 Colonial Revival home, nestled in a historic neighborhood of Bethesda, has undergone a remarkable transformation that melds its historic elegance with modern living. A carefully executed addition has more than doubled the home’s square footage, complemented by a full interior renovation and the construction of a new detached garage. The addition, designed with six-over-six double-hung windows and three front-gable dormers roofed with reclaimed slate, cleanly integrates with the original structure, preserving the home’s classic charm. The rear extension, decked in fiber cement lap siding, incorporates a screened porch that blends indoor and outdoor spaces, creating an inviting retreat. Inside, the interior design reimagines the layout for modern functionality, thoughtfully adapted to meet contemporary living standards while respecting the home’s historic character. The new detached garage, with its classic carriage door design, enhances the property’s convenience while harmonizing with its period architecture. Outdoor improvements include a stone patio, grill terrace, and a stone seating wall to further elevate the property’s usability and aesthetic.
