Authorship

Sloan became a prolific author on architecture most notably for The Model Architect as well as City and Suburban Architecture and Sloan's Constructive Architecture (1859). In 1861, he wrote Sloan's Homestead Architecture and American Houses, and A Variety of Designs for Rural Buildings. Sloan also reached thousands of potential customers through the pages of Godey's Lady's Book, which began publishing his designs in 1852.

"The man who has a home," wrote Sloan in 1871, "feels a love for it a thankfulness for its possession and a proportionate determination to uphold and defend it against all invading influences. Such a man is, of necessity . . . a good citizen; for he has a stake in society."^[4]

Economic downturns and work outside Philadelphia area

Economic downturns in the late 1850s as well as the American Civil War put a halt to his professional success and Sloan briefly left Philadelphia for New York in 1867. Important examples of his later work are found outside Pennsylvania, notably in Morganton, North Carolina's Western State Asylum for the Insane.^[1] Sloan ended up building about 20 hospitals for the insane based on the "Kirkbride Plan System".^[5]

Sloan enjoyed some later success in North Carolina, opening an office in Raleigh, where he died on July 19, 1884.^[1] His body was buried in Mount Moriah Cemetery, Philadelphia, Lot 11 Sec 20.^[2]
