Hearthstone Castle is a three-story, sixteen-room stone castle with associated outbuildings built between 1895 and 1899.
It is located in a wooded setting at the crest of a hill to the east of Brushy Hill Road in Danbury, Connecticut.
The complex is centered on the castle, which is essentially early Norman in form but incorporates elements of many periods of castle architecture as well as features commonly associated with styles of the late nineteenth century.
Outbuildings, all Shingle style, include a caretaker's cottage, carriage house, pump-house, barn, woodshed and water tower, clustered on higher ground to the south of the main building.

The eminence upon which Hearthstone Castle is built is approximately 650 feet above sea level and commands panoramic views to the north and east.
A pair of large granite gateposts with globe finials stand at the entrance to the property, on the east side of largely rural and undeveloped Brushy Hill Road.
A steep 800-foot-long gravel driveway ascends to the buildings, which cannot be seen from the road.

The castle occupies the brow of the hill.
Its east wall is built upon a retaining wall which is a direct continuation of the steep hillside, and then curves across the north side.
The castle is rectangular in shape, constructed of unfinished local granite over a core of brick.
Its dimensions are approximately 45 feet × 83 feet, and it has a flat composition roof, which is surrounded by a parapet with battlements created by pointed, upturned stones.
The main or front section of the building features D-ended towers at the northeast corner and beyond the northernmost bay of the west elevation.
The end bay of the north facade, located between these two towers, is beveled.
An 11-foot-wide veranda on a stone base extends from the south end of the east elevation around the north facade to terminate at a stone porte-cochere to the north of the D-ended tower on the west elevation.
Its roof is supported by stone piers which rise above it, and it features a denticulated cornice.
The porte-cochere has a flat roof and three pointed-arched openings, with buttresses suggested on the outer piers.
 In addition to the two towers, there are corbelled bartizans on the southeast corner and on the north facade, and a square chimney on the southeast corner.
The corners of the building are reinforced with large stones, some of which resemble quoins.
Bands of vertically set stones project below the parapets on the towers.
Segmentally arched openings at ground level admit light to the basement, and ventilate the area beneath the veranda.

The windows on the lower two stories are trabeated, with granite slab lintels and sills, while the third story is lighted by pointed and round arched two over two windows.
Fenestration is irregular, with large triple windows in the south and east elevations on the first and second stories and in the second story of the north facade.
On the east and west elevations, other windows are narrow but irregular in size, and are placed diagonally to light interior staircases.
There is a slit-like window in the south elevation, and in the west elevation a narrow window with bull's eye art glass.
The rear of the building is a two-story, flat-roofed kitchen wing, 18' x 23', which contains a rear entry.

The front entry is trabeated with a granite lintel and features a double-leaf, semi-glazed door with carved Gothic tracery and sidelights which opens onto an entry hall.
The hall features paneled wainscoting, cased and studded beams carried on consoles with carved scrolls, and a fireplace with a denticulated and modillioned mantelpiece carried on consoles carved in the shape of lions, all in oak.
To the east of the entry hall is the music room, which has molded door and window surrounds and a peach colored marble Neo-Classical fireplace with cable molding, a central carved scallop, and a denticulated mantelpiece carried on consoles.
The music room opens onto the dining room to the south.
The dining room features cased beams, molded door and window surrounds, paneled doors, and vertical wain
