Northwest Washington’s Kalorama neighborhood, known for its embassies, ambassadorial residences and elegant manor homes, also has townhouses, condominiums and co-ops in a variety of architectural styles.

Straddling Connecticut Avenue, the neighborhood offers proximity to restaurants, shops and nightlife. Yet its tree-lined, curved and sloping streets retain their quiet residential character. Kalorama Triangle, the section of the neighborhood tucked between upper Dupont Circle and Adams Morgan, features many former mansions with preserved facades that conceal new condos.

Casbro Development recently completed construction on three condos in Kalorama Triangle at 1922 Belmont Rd. NW, a classic example of the Mediterranean Revival style with its arched front door, wide front porch and mansard roof. The style was introduced in the United States in the early 19th century, according to Matt Vilardo, a realty agent with Brian Logan Real Estate.

“The building was a single-family home that had been owned by the same family 40 or 50 years, but it was in terrible condition inside and needed renovation,” Vilardo says.

Exterior preserved, interior new: The developers preserved the arched front door, the arched windows, the mansard roof and the wrought-iron window grilles when they converted the building to condos. The front berm has been landscaped to fit in with the greenery of nearby yards.

The builder added flagstones of Pennsylvania bluestone to the front porch, as well as copper gutters, widened the entrance to the lower-level unit and dug out the basement to allow for 9.5-foot-high ceilings.

“The building was completely gutted to the shell, so everything inside is completely new,” Vilardo says. “Each unit has its own separate level, as well as outdoor space, either a patio or a deck.”

Penthouse Unit 3, a three-bedroom, three-bath residence with approximately 1,700 square feet, is priced at $1.495 million. This two-level unit has high ceilings, hardwood flooring, an open floor plan and three tall windows with transoms facing the treetops and the street. The unit has a six-speaker home theater system and a private parking space.

“Each interior has slightly different features, but they all have high-end fixtures and finishes,” Vilardo says. “The penthouse unit has a three-inch-thick marble countertop and center island. We had to shut down the street and bring it in through the windows with a crane.”

The marble extends from the counter to the ceiling behind the six-burner stainless-steel gas oven and grill for a dramatic focal point for the open room.

Wet bar, rooftop terrace: This level also has a full bath in the hall and two bedrooms, one with a private full bath. One of the bedrooms has a glass door to a balcony. Hardwood stairs lead to the upper level, which has a wet bar and glass doors that open onto the rooftop terrace. The adjacent master suite includes a second set of glass doors to the terrace and an unusual walk-in closet with an exposed-brick wall and windows. The luxurious adjacent bathroom has an oval soaking tub, a double-sink vanity and a glass-enclosed shower with a seat.

Unit 2, a two-bedroom, two-bath residence on the main level, is priced at $799,000 and has approximately 900 finished square feet. This residence has an open living and dining area with arched front windows facing the street, a walk-in pantry and a movable kitchen island. The kitchen has a polished Brazilian marble counter and backsplash and dark wood cabinets.

Toward the back of this home are a closet with a stacked washer and dryer and a full bath. The master bedroom has a private full bath and glass doors to a private terrace. The second bedroom has two walls of windows with transoms.

The lower-level Unit 1 has a private entrance with a flagstone terrace in the front and a private flagstone patio in the back. This two-bedroom, two-bath residence has approximately 1,100 square feet and is priced from $689,000.

The open floor plan includes a living and dining area and an open kitchen with a center island with pendant lighting, stainless-steel appliances, white cabinets and a subway-tile backsplash. The hall bath includes a distinctive colorful tile wall in the glass-enclosed shower.

Nearby is a closet with a stacked washer and dryer. The master bedroom and the second bedroom have glass doors to the patio. The master bedroom also has a private full bath and a dressing area with a double-door closet.
