The Kyle Estate, also known as the Rosbrook-Kyle House, is an interesting Victorian residence at 18 Park Street in the village of Florence in Northampton. It was originally constructed as a one-and-a-half story Gothic cottage around 1865. The land on which the house was built was purchased by Francis O. Rosbrook in 1850 and passed through three other owners before it was purchased in 1844 by Oscar N. Kyle, treasurer and manager of the Florence Machine Company. He hired local architect Charles H. Jones to remodel the cottage, which was elevated one story. The front porch on the ground floor features Eastlake elements and the ornament of the porch on the second floor suggests Middle Eastern design. A three-story octagonal tower was also added at the southwestern corner of the house. The altered house combines different architectural styles, with the Gothic style retained on the original Gothic section (now the second floor and attic gable). The second floor and part of the gable have board-and-batten siding, while wood shingles cover the third story of the tower and the upper section of the gable. The house is now divided into apartments. Behind the house is an architecturally interesting carriage house. It has a large round tower with a wood-shingled bell-shaped roof.
