Colleen Healey Architecture has revamped a home on a radial lot facing Washington DC’s Logan Circle, retaining historic details while updating the spaces for contemporary living.

The renovated eight-bedroom house fronts Logan Circle, one of the city’s grand rotaries that connects several major avenues, created as part of engineer Pierre L’Enfant’s original master plan.

Due to its location, the lines of the building’s plan are subtly radial and therefore none of its walls are parallel to one another.

This proved a challenge for local architect Colleen Healey, who had no choice but to embrace this and incorporate the unusual parameters into the design.

“The effects of the radial lot are not only informed design decisions, but provided inspiration for rounded references and other geometric subtleties,” said the studio.

Built in 1883, the home’s three-story front section once comprised an entry hall, living and dining room on the ground floor, an owner’s suite and two spare bedrooms on the first floor, and two further bedrooms on the second.

The rear section is set at half levels and features smaller rooms and lower ceiling heights.

“Much of the original elements and bones of the house were in great shape and our clients desired a mix of historic charm and modern upgrades,” said Healey.

The back portion received the most attention during the renovation, remade as the “heart of the house” where a large kitchen features a U-shaped quartzite counter and a garden room faces the patio.

Skylights were created on the roof, allowing light to wash down the original brick walls and through the gaps between the wooden floor joists exposed above the kitchen.

Since the walls were positioned at angles, the wood flooring was laid diagonally in this area.

An arched opening between the two sections of the house was extended to 10 feet, allowing a powder room and storage space to be added behind its plaster surfaces.

“A new finished lower level and existing bathrooms are upgraded with a mix of vintage and industrial charm, blending the tastes of both clients and using original elements to the house whenever possible,” Healey said.

The upstairs bedrooms and bathrooms retained their dark wood window trims and shutters, baseboards and ornate fireplaces, but were refreshed with bright white walls and contemporary light fixtures.

However, in the primary suite, the fireplace was removed to make way for a widened headboard and art wall.

In the remaining rooms, items belonging to the clients are combined with mid-century furniture and minimal lighting to contrast the historic details.

“The result is a modern sensibility that unites the old and new spaces and creates a striking juxtaposition with the home’s architecture,” the team concluded.

This isn’t the first time that Colleen Healey Architecture has worked with an atypical lot. The studio previously restored and expanded an early 20th-century carriage house in Maryland, on a site shaped like a smoking pipe.
