Hepburn Estate

The Hepburn Estate

In May of 2004, a well-known and highly successful New York builder, and his family purchased the Hepburn Estate. Ten years later, in order to satisfy the needs of their growing family, it was decided to add to the estate.

The Katharine Hepburn Estate is located on Long Island Sound in the Fenwick section of Old Saybrook, Connecticut. The main house was rebuilt in 1938 after the Great Hurricane of 1938 destroyed the original structure.

Hepburn adored the property and spent much of her free time there. She enjoyed a swim in the waters of the Sound each morning, even during the milder winter days when there was still snow on the ground. The Hepburn family owned the home until a year after her death in 2003. In May of 2004, a well-known and highly successful New York builder, and his family purchased the home.

This past year, it was decided to add to the estate to satisfy the needs of his growing family. A local architect was hired to design a guesthouse that was positioned as close to the Long Island Sound without actually being in the water.

This structure, being built in a V-zone (velocity zone), needed special considerations when designing the foundation. This 4200 sq. ft., 2-story guesthouse was designed with a CHANCE® Helical Pile Foundation System and breakaway walls to endure the wrath of raging waters during any upcoming storms. A breakaway wall is not part of the structural support of the building. Through their design and construction, breakaway walls are designed to collapse under specific lateral loading forces, such as waves and debris, without causing damage to the elevated portion of the building or supporting foundation system.

Helical Pile Deep Foundation InstallationRobert Barnabei Contracting installed twenty-four helical piles to a depth of twenty to thirty feet to achieve the 80 kip ultimate torque. The geotechnical engineer chose the CHANCE® RS3500 Round Shaft Helical Pile Foundation System for the extra lateral stability in the upper layers of the soil that would be exposed to coastal scouring during heavy rains and storms.

All of the helical piles were installed in two days and capped off with twelve-by-twelve pile caps. The pile caps and upper pier will be encased within the grade beam. Tied into the grade beam will be concrete posts that will support the breakaway walls. The structure will be elevated thirteen feet above the flood plain which will protect the home from future flood damage during hurricanes.
