This Elkins Park house was Kahn's earliest residential commission. It was designed in 1940 for Jesse and Ruth Oser; Kahn and Jesse Oser went to Central High School in Philadelphia together and remained friends. The house sits on the former estate of hat baron J.B. Stetson, so it already had some features that Kahn had to work around: “He had little choice,” reads The Houses of Louis Kahn, “but to situate the house above, on a north-facing slope.” The fireplace, surrounded by Mercer tile, was a standout in the press, as it was the anchor of what Kahn called the conversation nook—a kind of dedicated family gathering spot that would be replicated in later residential projects.

The Philip and Jocelyn Roche House in Whitemarsh Township was built around 1947 (there is some confusion about the construction timeline), and features a Kahn-signature brick wall in the living room. Surrounded by a lush landscape, the three-bedroom home also has ties to Oscar Stonorov. It last sold in 2014 for $710,000.

Winner of the 1950 AIA Gold Medal, Kahn described the Weiss House in East Norriton Township, Pennsylvania, as "a house that is contemporary, but does not break away from tradition." The wood and stone structure, built between 1947 and 1950 for local menswear shop owner Morton Weiss and his wife, showcases Kahn's signature connection to the outdoors through a unique window system—residents can rearrange opaque and transparent panels in the living space to control the amount of light being let in throughout the course of the day.

This future of this home remains uncertain and in the hands of a developer. Though neighbors rallied to save the home from demolition, it has been on and off the market for years.

Built between 1958 and 1962 for Norma and Bernard Shapiro, Kahn's clients knew exactly what they wanted from their Kahn-designed home: Privacy. They had to have been pleased with the result; the family still owns the residence. Built on a steep slope, the upper entry level features the living area, while the lower level contains sleeping areas and a den.

The house he designed for Margaret Esherick, niece of sculptor Wharton Esherick, at 204 Sunrise Lane in 1959, is one of the architect's more well-known works. It was recently sold for a little less than a million dollars, a relatively small sum that some contribute to the fact that it has only one bedroom. Over the past couple of years, Kevin Yoder Design has led a major restoration of the home that earned national recognition from Docomomo.

You may remember that the Clever House was recently sold, and for less than $300,000. The house was designed in 1957 for Fred E. and Elaine Cox Clever, who commissioned the starchitect to build the Cherry Hill, New Jersey abode for them after seeing his influential "Trenton Bath House." The three-bedroom, two-bath home sits on .62 acres was built during a period in which Kahn was interested in structures based on triangular geometries, the central element of the home is its large living room, which features an 18-foot ceiling composed of four large angular gables, each fitted with a large triangular window. This living area is surrounded by five smaller rooms, each with its own pyramidal roof. Today, the new owners Kevin Lyons and Jennifer Smith are currently restoring the home bit by bit.

The two-story Korman House in Montgomery County, built in 1973, was Kahn’s last completed residential work and also his largest. Steven and Toby Korman wanted ample space to raise their three boys, and Kahn collaborated with E. Arol Fesmire, who he had also worked with on the Fisher House, to build a 6,500-square-foot home. According to Whitaker and Marcus in The Houses of Louis Kahn, it still feels just as intimate as his smaller designs. Current status: The Korman’s oldest son Larry and his family have lived in the house since 1998, and the structure has been meticulously preserved.
