As a Washington native, architect Christian Zapatka has long been drawn to homes in the Kalorama neighborhood. When a chance to work there on a Waddy Butler Wood house came up, it was too good an opportunity to pass up.

“Kalorama is a laboratory of great examples of 20th-century architecture, especially in the neo-classical revival style,” he said. “Waddy Wood is one of the major figures of that period.”

A self-taught architect, Wood designed many residences and important buildings in and around Washington. Some of his more well-known buildings include the Interior Department and Pepco facilities, the Woodrow Wilson House, the Thomas Balch Library in Leesburg and part of the Chevy Chase Club.

“His charm and knowledge of people led him to gain many important commissions,” Emily Hotaling Eig, founder of EHT Traceries, wrote in an email.

Hickory Ridge in Howard County | Hickory Ridge “is considered today one of the truly splendid homes built by the Maryland Ridgeleys,” Celia M.

The 1923 house was commissioned by M. Carter Hall, the general solicitor for the Chesapeake & Ohio Railroad. After Hall left, Rear Adm. Charles Wilson Dyson, who was awarded the Navy Cross and earned the Distinguished Service Medal for his work in propeller design, lived there.

Sen. Wallace White Jr. (R-Maine), a former Senate majority leader, and his heirs spent the longest time in the home, residing more than 30 years. After White’s death, his wife, step-daughter and step-granddaughter — all of whom were named Nina Lunn — continued to call 2449 Tracy Place home. The Lunns were colorful Washington society figures.

The Lunns were followed by another socialite with a flair for entertaining. Fur heiress Renee Zlotnick Kraft and her husband, Alvin, hosted lavish parties, sometimes renting a champagne fountain.

Before the home underwent its most recent renovation, it was the residence of the ambassador from Gabon.

Zapatka renovated the home in 2014. Most of his work was stripping away layers of bad renovations over the years, including fiberglass fireplace surrounds, cheap wood flooring, dated hardware and overly ornate elements.

“There was really no interesting detail intact,” Zapatka said. “It was a little bit of a blank slate to work with. The good part of Waddy Wood, the overall volume, that sweep of rooms across the front, was still there. It was just a matter of bringing out the best of it.”

Because the home is more horizontal than vertical — unusual for a city house — the entrance hall, living and dining rooms stretch languidly across its width.

“That’s the best part of the house, that sweep of three rooms across the front,” Zapatka said.

The front of the house remains classical in its design, while the back is more modern with staircases with glass railings.

“I’m very pleased with those front rooms,” he said. “We made the most of what was there. We refined and improved the details. And then the back of the house, we made it feel a lot more open and airy.”

The six-bedroom, seven-bathroom house is listed at $5.9 million.
