The main house is a 2-1/2 structure, its walls and foundations built out of marble quarried either on the property or in West Rutland.

The original main block is built out of ashlar stone, 20 inches (51 cm) thick, laid in irregular courses.

A portion of the larger property is in agricultural use, and hiking trails lead to the quarries from which stone for the original house was taken.

The main house was built sometime before 1820 by Martin Manley, on land originally purchased by his father George.

Lefevre, the son of a Central American diplomat, was an author and entrepreneur, who established the first electric company providing power to Dorset.
