The house is located on the west side of the road roughly 1.4 miles (2.3 km) north of the Vanderbilt Mansion National Historic Site at the north end of downtown Hyde Park and 1 mile (1.6 km) south of the hamlet of Staatsburg.
The surrounding terrain is gently rolling, just east of a 100-foot (30 m) rise up from the Hudson River a quarter-mile (400 m) to the west.
It is extensively wooded, with a few clearings for a nearby yacht club to the south, the former summer camp on the property, and the Anderson Center for Autism a thousand feet (300 m) to the north.
On the opposite side of the road, is a large tract of unbroken woods extending almost to New York State Route 9G two miles (3.2 km) to the east.

The house's main block is a one-and-a-half-story three-bay structure of uncoursed fieldstone on an exposed stone foundation.
It is topped with a cross-gabled roof sheathed in asphalt shingles and pierced by brick chimneys on either end.
There are additions on the north and west sides, and small porticos sheltering both entrances.

On the east (front) facade, the stone has been covered with stucco, which was later scored to suggest a smooth-cut ashlar pattern.
It has begun to flake and spall near the roof and foundation lines on the south of the main entrance.
A short set of unpainted wooden steps leads up to a porch of the same material, with guardrails on the sides.
Two plain square pillars support the gabled portico roof, with clapboard in the gable field.
To its sides, each bay has one double-hung six-over-six sash window with paneled wooden shutters.
A wide plain frieze with simple cornice and bracketed eaves mark the roofline.
The gable field above the main entrance is built of timber frame.
It, too, is faced in clapboard.
In its middle, is an arched two-over-two double-hung sash window.
Its roofline has a similar treatment as the one below, except for having smaller brackets in pairs.

On the south, the windows, entrance and facade treatment of the first story are identical to that of the east.
The portico-roof is supported by narrow metal poles, but is otherwise the same as its larger counterpart on the east.
The gable field above it similarly set in clapboard, however, has two smooth-arched one-over-one double-hung sash windows.
The roofline treatment matches that on the east cross-gable.

The stone on the west elevation is not stuccoed, only painted.
A single narrow one-over-one separates the south corner from a shed-roofed addition with modern siding and paired storm windows in each face.
On the north is another, similar addition, larger and with a smaller gabled roof.
It has almost continuous screened windows, serving as a sunroom.
There is no stucco on that side of the main block, either.

A plain molded surround, topped by blocks with bulls-eye centers, sets off the main entrance door.
Above it, on the lintel, is carved "GR 1769".
The door itself has four lights on its top and four wooden panels below.

Inside, the house has many of its interior features intact.
It has a central hall with wide planked wooden flooring.
In the rooms are original mantels; the kitchen has a large stone fireplace with wooden lintel.
Many of the original wooden four-paneled doors remain.
The original ceiling hand-hewn exposed beams are still present, and the staircase to the garret features an original wooden newel post and balustrade, among many other original wooden and plaster finishes in the house.
