Tregaron Estate

Tregaron Estate is a 20-acre property set in woodland with Georgian-style architecture and several outbuildings. It features a two-story brick mansion, greenhouse, Russian-style dacha, gardener's cottage, and carriage house arranged around formal gardens and natural streams.

The property was designed in 1912 by architect Charles Adams Platt for James Parmelee and received its current name when Ambassador Joseph Davies purchased it in 1940. Davies and his wife Marjorie Merriweather Post, who lived there from 1942 to 1958, added Russian-inspired elements to the grounds.

The name comes from a Welsh estate that inspired the owners who took residence here. The gardens and buildings show how wealthy American collectors brought European influences into their country homes.

Access to the property is through the entrance on Macomb Street, a short walk from Cleveland Park Metro station on the Red Line. Wear comfortable shoes since the grounds are uneven and include woodland paths and garden areas to explore.

The Russian-style dacha was added by the Davies family and reflects their collecting passion and connection to Soviet culture. This unusual feature sets the estate apart from other Georgian homes in the area.
