One of the earliest houses by Coughlin and Ayres, the Halff House stands in the once up-scale neighborhood of Tobin Hill. The architects combined a Richardsonian entrance arch and porch columns with Prairie School details in the column capitals, dentiled entablatures, stone bands, and urns. The green-glazed tile roof shades the two-story house with extraordinarily deep overhangs. The massing of the projecting front porch with its hipped-roof pavilions is rather Japanese in character.
