The large house contains three stairwells and many outbuildings, such as the Spring House, Carriage House, and barn, which still remain in use on the property. The house originally had a two story porch where the kitchen is now located. Although the porch is gone, the large pillars that sustained the structure are still evident in the kitchen.
Built in 1837, the Quail House is an excellent example of the colonial architecture of the time period. Complete with Greek Revival and Palladian-style architecture, the house is largely preserved. Interesting features of the home include: the plain stone lintels; elegant interior woodwork; the original blacksmith-forged iron lightning rods and door hardware; a regal stairwell banister imported from Europe and carved from one cherry tree; and double chimneys connected by a gable curtain.
In 1811, William Quail, a very successful farmer and stock broker from County Down Patrick in Ireland, purchased 147 acres of land in Washington County, Pennsylvania. This property would become known as the Quail Acres Estate. William Quail left the property to his son, David Quail, who purchased additional land for the estate. Though the property expanded, it was not until David’s son, William McAlpine Quail, inherited the property that the Quail Mansion was finally constructed.
Of the original 180 acres, 4.5 exist today, which provide a wonderful outdoor space forweddings and other events on the side terrace lawn.
Palladianism is based on symmetry, which the house dramatically displays with its front porch columns, window placement, and parallel chimneys. Many features from the original structure remain including the imported European hardwood floors and woodwork. At one time, the roof was covered entirely in clay tile shingles that the Quail family had imported from Belgium.
In the early 1990's, Washington County Businessman, Jerry Polen and his wife Nancy, acquired the property and restored the house with respect to much of its original character.
During its heyday, the Carriage House, which is located adjacent to the restaurant, had large bi-parting doors to accommodate the entrance of horses. The horses were utilized to draw the estate’s carriage as it was driven by the Carriage Master who was essentially the estate's chauffeur. He lived above the horses in the upper part of the structure, was well-dressed and was in charge of keeping the harnesses and carriage polished, as well as taking care of the horses.
