About This Home

MID MOD MEWS by OPaL **some of the most affordable all-new single family homes inside the beltway** - Five all-new, mid-century modern single-family homes are coming to super-walkable Cabin John. Located just off the Potomac River and C&O Towpath, these elevator-ready residences are steps from local eateries, markets, playgrounds, tennis courts and even Glen Echo Park with great camps, classes, puppet shows and the famous Dentzel Carousel. If you have kids - you're in one the best school systems in the country; if not, there's a veterinarian right across the street.
These right-sized homes perfectly blend classic mid-century architecture with forward-thinking design. Walls of windows and volume ceilings allow natural light to brighten and warm the home. Classic mid-century features like a screened porch, wood burning fireplace and carport pair seamlessly with modern features like green roofs and Energy Star efficiency. At the heart of the home, an all-pro kitchen stands ready for extended family gatherings or quiet solo evenings. Walls of glass open to the screened porch and right-sized backyard that could be upgraded for the perfect patio vibe. The primary bedroom features an oversized suite with walk-in closets, pitched ceiling, optional skylights, walls of glass, west-facing balcony, and a terrific ensuite bath to include: a double vanity, water closet and efficient wet-room with glass block if you'd like. Two additional guest rooms, a dedicated work-from-home space, and the laundry complete this floor. The versatile fourth level—with optional full bath and elevator access—is perfect for a studio, extra bedroom, or a sunny space for you, a good book and your four-legged buddy. The lower-level rec-room with an additional bedroom and full bath come standard; the perfect space for binging Netflix or Bravo. Maybe even just use the basement for storing the stuff you just can't part with yet. Pre-construction sales are happening now for 2027 deliveries. Developed, sold, and warrantied by OPaL DC—a seven-time DC Home of the Year winner, recipient of dozens of national and local design awards, and your Cabin John neighbor.
