This three-story atrium is crowned by a Venetian stained glass skylight, a vibrant mosaic of reds, blues, and golds that bathes the hall in an ethereal glow.

The skylight is not just decorative; it sets the tone for the entire mansion, showcasing a deep appreciation for both art and natural light.

At the heart of the Great Hall is the marble-clad grand staircase, flanked by intricately designed wrought-iron railings. The staircase sweeps upward in a gentle curve, commanding attention without overpowering the space.

I remember standing at the foot of that staircase, craning my neck to take it all in, and thinking, “This isn’t just design—it’s poetry in stone and light.”


Formal Parlors

Shadow Lawn’s formal parlors redefine majesty. Their gilded coffered ceilings are works of art in their own right, with intricate patterns of gold and bronze that shimmer in the ambient light.
