Meridian House is a residential jewel, designed by renowned architect John Russell Pope, who designed the Jefferson Memorial, the National Gallery of Art (West Building) and the National Archives. In 1929, Meridian House was described by Architectural Forum as:
"Perhaps as fine a piece of work of its kind as this country can show... Certainly the manner of this house has not in this country been better done, not only in terms of stylistic authenticity, but in terms of pure architecture, meaning good taste in selectivity, in elimination, in execution. It cannot from its nature do otherwise than set a standard which should endure permanently."
After undergoing a major renovation in 1994, Meridian House's principal rooms retain their architectural detail as well as some of the original decorative features, such as the 18th century European overdoor paintings and antique brass hardware and lighting fixtures. The classical symmetry of the Louis XVI style is reflected throughout the house.
The dining room features a beautiful Mortlake tapestry, which has been dated by experts as late 17th century. The tapestry, purchased by the Laughlin family in England at the turn of the century, depicts the legendary reception given Alexander the Great by the Greek philosopher Diogenes. An almost identical tapestry hangs in Holyrood Castle in Edinburgh, Scotland.
The reception gallery remains much as it was at the time the Laughlin family occupied the house. The wrought-iron and marble-topped side tables, the four Waterford crystal torcheres in the corners, the blue Chinese temple jars, and the antique clock and barometer on the mirrored walls are all part of the original furnishings. The loggia, which links the major reception rooms and rear garden, includes four marble busts sculpted in France, representing the four seasons. The dining room also features two portraits one of Ambassador Laughlin and one of his daughter, Gertrude Laughlin Chanler, as a child. A portrait of Mrs. Laughlin hangs nearby in the Chairmen's Study. All three were painted by Philippe de Laszlo, the renowned portrait artist of the early 20th century.
The Latin inscription "Quo habitat felicitas nil intret mali" appears over the front door and translates "Where happiness dwells, evil will not enter." The inscription over the rear courtyard doors reads: "Purior hic aer: late hinc conspectus in urbem," meaning "Purer here the air whence we overlook the city," a quotation also inscribed on a house at the top of Rome's Spanish Steps.
The rear and side gardens largely retain their original design. The pebbled courtyard has 40 linden trees, imported from Europe when the house was built. The statues throughout the garden are original to the house, as are the statues at the four roof-line corners.
