Inside a Ultra Luxury McLean Mega Mansion | 15,000+ Sq Ft Estate Tour

Welcome to 1174 Old Tolson Mill Road — a grand luxury estate tucked away on a private road in prestigious McLean, Virginia. Set behind motorized wrought-iron gates and surrounded by two acres of fully fenced grounds, this 15,000+ square foot residence masterfully blends timeless old-world architecture with cutting-edge modern technology.

From the moment you arrive, the estate commands attention. A double-height portico supported by Corinthian columns introduces a dramatic marble-clad foyer with a sweeping bifurcated staircase inspired by New York’s iconic Four Seasons. Soaring ceilings, intricate millwork, and curated finishes define interiors designed for both formal entertaining and refined everyday living.

The great room rises nearly 25 feet and centers around a floor-to-ceiling fireplace, seamlessly integrating invisible speakers for a clean architectural aesthetic. The chef’s kitchen is a true showpiece, featuring dual islands, custom cabinetry, and a full suite of Miele, Sub-Zero, and Wolf appliances. Smart home integration via Crestron allows complete control of lighting, sound, security, cameras, blinds, and climate — all from your smartphone.

Upstairs, the primary suite spans over 38 feet and delivers a private retreat experience with a screened-in balcony, spa-inspired travertine bath, hot tub, and custom dressing spaces. The lower level transforms into a private entertainment club with a professional cinema, twin wine cellars, wet bar, recreation lounge, wellness center with sauna and steam shower, and additional guest accommodations.

Designed with fortress-level construction and over $350,000 invested in advanced security and technology systems, this estate offers 18+ security cameras, hardwired alarm integration, cell boosters on every level, a private elevator, dual garage lifts for five-car capacity, and a full backup Generac generator.

Approved plans for a resort-style pool and lower-level expansion further elevate the estate’s long-term potential. Combining privacy, scale, craftsmanship, and next-level engineering, this McLean mega mansion represents refined American luxury at its absolute peak.
