[1] In 1903 and 1904, prominent Buffalo businessman Seymour H. Knox I had a new 13,700 square foot Beaux Arts style mansion and carriage house constructed at 1045 Delaware Avenue.

Mr. Knox commissioned celebrated architect Edgar E. Joralemon to design the three-story residence, which features 27 rooms and 11 fireplaces.

[1] That same year, his spouse, Grace (née Millard), purchased property on Delaware Avenue north of Summer Street in Buffalo.

The resulting structure was a stone mansion built over the course of three years that was completed in 1918, which is today known as the Grace Millard Knox House.

[3] The Bishop's previous residence, immediately south, was subsequently demolished, explaining why Blessed Sacrament Church is set back farther than any other primary building along Delaware Avenue in Buffalo.

In 1953, the Diocese of Buffalo purchased a new residence for the Bishop at 77 Oakland Place and transferred custody of the former Knox estate to New Cathedral Parish for use as a convent for the Sisters of St. Joseph.

[4] In the years ahead, Singer invested more than $250,000 into the property to restore the second and third floors to their original configuration, selectively added overhead lighting to support office functions, installed air conditioning, and replaced plumbing throughout the main residence.

It is composed of triple wythe exterior walls of Roman brick with a continuous white marble water table and trim, including window and door headers.

The third floor is crowned with an entablature featuring a projecting cornice decorated with a parade of lion heads above ornamented modillions with acanthus leaves that alternate with rosettes, as well as egg-and-dart and dentil molding.

The rear portion of the house is only two stories tall and is clad with yellow Roman brick from grade with marble trim.

The second-floor porch was extensively rebuilt in the fall of 2020 due to rotted wood columns, balustrades, and box beams.

The roof overhang, including fascia, cornice, gutter, and soffit ornamentation, are composed of painted tin.

A one-story “manure pit” room originally extended from the north side of the building, topped with a tin roof.

A yellow Roman brick chimney-like manure vent incorporated into the northeast corner of the building remains in place.

The west and east sides of the second floor of the Carriage House were originally laid out to accommodate the communal quarters for a gardener, housekeeper, and coachman.
