The Webb Horton House is a 40-room mansion in Middletown, New York, United States, designed by local architect Frank Lindsey.

The mansion was designed by Frank J. Lindsey, a local carpenter turned architect, for Horton, a Delaware County native who had built a fortune starting from a Narrowsburg tanning business, later benefiting from an oil strike in Sheffield, Pennsylvania.

In addition to the current complex, there was a conservatory and hothouse on the site, as well as a frame house facing East Conkling.

In 1911 the Horton children had bought the house at South and East Conkling, later tearing it down for the sunken garden.

[1] Morrison's will left the estate to Horton Hospital (also named after the house's first resident) in Middletown, with his wife Christine[3] granted life tenancy.

The hospital was not willing to sell at that time since it had planned to do so upon Mrs. Morrison's death in the hope of getting the best possible price to pay down its debt.

While many more modern buildings have been developed on the campus, the mansion, stables, and other outbuildings are still used for educational, administrative, and custodial purposes.

The college has made a few changes: converting one of the upper balconies to an office, enclosing the porches, and putting in new vestibule doors.

[1] The house sits on a low hilltop on South Street between East Conkling and Grand View avenues in the southwest quadrant of the city.

[1] The college campus surrounds the house on three sides, with a large modern building called Hudson Hall immediately to the east.

A 6½-foot–high (2 m) stone and iron fence, ornamented with scrolls and the initials "WH" on the main gate, screens the house from South Street and the parking lots across it.

The conical roof has three dormers, each gabled, decorated with marble in a shell motif and topped with a finial.

It is topped with a carved cartouche consisting of the WH monogram, ribbons, fruits and oak leaves.

Above it is a frieze similar to the one on the tower, a molded stone cornice, three dormers and a hipped roof with a conical top over the bay.

[1] At the other end of the northeast facade, with fenestration similar to the rest of the house, is a flat-roofed balustraded porch, now enclosed.

In the center is a projecting curved section, three bays wide, three and a half stories high, similar to the one opposite with a balcony.

At the top of its stairs is an iron and glass vestibule with intricate carved cartouches, scrolls, foliage and circles.

The major rooms are off to the south, including the circular salon, linked to the stained oak library by pocket doors.

Its ceiling, right under the tower's conical roof, is ornamented with ribs and Moorish Revival relief designs.

The Webb Horton House is typical of the country seats built by the wealthy of late 19th-century America, though in an urban or suburban setting.

It shows the influence of Artistic Country-Seats, an 1887 pattern book by George William Sheldon, which had houses with many different rooms.

The masonry exterior is a Richardsonian Romanesque touch, the complicated roofline is in accord with the Queen Anne Style, and the classically inspired decorations a nod to the Beaux-Arts mode.
