The Read House is located in central downtown New Castle, facing the Delaware River across The Strand midway between Harmony and Delaware Streets. The house's view of the river includes a surviving portion of the wharf of George Read. The house is a 2-1/2 story bric building, with a side gable roof and a stone foundation. It has four chimneys, two built into each end wall, with a curtain wall between. The roof's peak is truncated, the flat top section ringed by a low balustrade. The front face of the roof has two dormers, topped by gabled roofs and covering round-arch windows. The main facade is five bays wide, with sash windows set in rectangular openings, with stone sills and splayed stone lintels. The main entrance is at the center, with flanking sidelight windows and pilasters, and a large half-round transom window above. On the second story above the entrance is a Palladian window, its sections flanked by narrow pilasters. To the rear of the main block are two large ells, giving the house a total area in excess of. The house was built in 1793 for George Read Jr., the son of George Read, one of Delaware's leading statesmen and a signer of the United States Declaration of Independence. The younger Read was a successful lawyer and businessman, whose wealth enabled him to build what was then the largest private residence in the state. Stylistically, it is an important early example of Federal period architecture, taking inspiration from several Adamesque houses built in Philadelphia a few years earlier.
Garden
The house was purchased in 1836 by John M. Clayton, another Delaware statesman, after Read's death. The third owner was William Couper, a wealthy New Castle businessman who had grown up in the house of George Read I, which stood next door to this house. Houses on either side of this one, including the George Read I House, were lost to fire in 1824. Couper used the open space created by the fire on the south side of this house to establish a formal garden beginning in 1847. The basic layout of the garden appears follow Couper's basic plan, although the type of plantings is likely not original. Features of its design include brick walkways that wind between the beds, and two gazebos, placed by the Delaware Historical Society at locations of similar structures seen in late 19th-century photographs.
Subsequent history
Couper was a bachelor, who occupied the house along with a number of other family members. After his death, they continued to reside in the house until the last, his niece Hettie Smith, died in 1919. The house was then acquired by Philip and Lydia Laird, who were involved in New Castle's early historic preservation movement, and undertook to maintain the property's historic integrity. Lydia Laird bequested the property to the Delaware Historical Society in 1975. The Society has since undertaken a full restoration of the property, and interprets it primarily in the period of the Read ownership, although some rooms reflect the styles of subsequent owners. The house is open Wednesday to Sunday year-round, closed only on some holidays; admission is charged.
