[1] Kohler commissioned the Olmsted Brothers, well known for creating Central Park in New York City and the Harvard and Stanford campuses, to design the grounds of the estate.

The grounds were landscaped in the English tradition to accentuate the natural beauty of the site that captivated Walter and his wife Charlotte.

[8] The home was expanded and remodeled with a four-story addition added at the east end, and opened in 2001 as an exclusive private membership club.

The house was notable, partly because unlike most Tudor Revival homes constructed in the time period, it was not designed with a modern interior.

The open solarium in the southern facade was surrounded in four-centred archways supporting additional floors of living space above.

Other design elements included tiled floors, carved stone fireplaces, and stained glass medallions in the windows.

This large room measured 20 by 42 feet and was paved with Vermont granite slabs, a wooden ceiling supported by cased oak beams, white stucco walls and numerous four-centred arch openings.

The house was furnished with many antiques such as Kurdistan rugs, William and Mary highback chairs, Flemish tapestries, a Queen Anne bookcase (c. 1719), and a Chippendale chest (c. 1780).

[8] Exterior restoration work included replacing much of the original stucco on the gables ends with a modern EIFS in matching textures and colors.

The primary elements of the landscaping are rustic stone walls, rock gardens, sunken lawns an allée of evergreens, formal beds, and a bowling green.

A painting of the tree by Charlotte, titled Earthbound, was featured in a gallery display of Wisconsin art sponsored by The Milwaukee Journal, in 1930.
