Chelsea mansion, the 40-room North Shore residence listed on the National Register of Historic Places, will open its doors to the public in October following a makeover by 19 of Long Island’s top interior and exterior designers, announced Nassau County Executive Thomas R. Suozzi.

The Chelsea designer show house kicks off with a fund raiser on Friday, October 3, from 7 - 10 p.m., with regular public tours beginning on October 4 and running through November 16, Wednesday through Sunday from 11 a.m. - 5 p.m. (last tour starts at 4 p.m.).

Admission is $25 for adults and $15 for senior citizens and children 10 - 17 years of age. All proceeds will benefit the restoration of the mansion and gardens.

Chelsea is located on the north end of the spectacular 550-acre Muttontown Preserve in Muttontown, off 25A west of Jericho-Oyster Bay Road, on Muttontown Lane (south side of 25A). The mansion was built by Mr. and Mrs. Benjamin Moore in 1924 and is an outstanding example of the design prevalent during the latter part of Long Island’s Gold Coast era.

The architecture reflects a French Normandy style with English and Chinese influences. The building’s south side, courtyard moat and bridges showcase the Chinese influence, while the front elevation, roof and wings evidence the influence of 17th- and 18th-century French styles.
