Architectural Acorn Deck House on 3.88 Private Acres
This is not a typical suburban house—8620 Polk Street is an authentic Acorn Deck House, sited on a rare 3.88-acre parcel at the quiet end of a cul-de-sac in McLean’s Woodside Estates. The property’s mid-century modern vocabulary—brick and cedar cladding, exposed beams and vaulted ceilings—was conceived to connect interior and landscape. Floor-to-ceiling windows and broad decks frame a wooded, gently sloping lot that feels miles from the city while remaining an easy commute to Washington, D.C.
Inside, more than 6,300 square feet of living area unfolds across three levels with an open, purposeful plan. Living spaces emphasize texture and volume: vaulted ceilings, character woodwork and a fireplace anchor principal rooms. The fully finished lower level expands the home’s footprint with flexible recreation and media spaces, while five bedrooms and 5.5 baths are arranged for privacy and family life. Systems are maintained in excellent condition, and the home’s generous footprint includes a four-car attached garage and long private driveway.
Outdoor living is a defining feature: expansive decks step down into mature woods, offering multiple terraces for dining, yoga, and evenings under the trees. The large lot invites gardens, a pool, sport court, or simply the preservation of a private natural setting—rare in close-in Northern Virginia. Utilities include well and septic; buyers should review related inspection reports as part of any due diligence.
Location is quietly exceptional. Woodside Estates is prized for large lots, mature canopy, and top-rated school access. Tysons Corner’s shops and services are minutes away, Great Falls Park is within striking distance for weekend outings, and the Langley High School pyramid is a major draw for families. This property suits buyers seeking an architecturally significant home that delivers privacy, scale, and a strong connection to nature while remaining within close range of city amenities.

A factual market snapshot around 8620 Polk Street.
McLean’s luxury single-family market remains firmly in sellers’ territory. Inventory across the McLean corridor is tight—approximately 2.5 months of supply—while average days on market for comparable upscale homes sits near 31 days. Recent comp sales within one mile closed in the $2.5M–$2.7M range, supporting an estimated fair market midpoint around $2.6M ($412/SF) for architecturally distinctive homes like this one. Over the past year appreciation is modest (≈5%), with a stronger 20% gain over five years as affluent buyers prioritize privacy, lot size, and proximity to top schools.
Single-family estate properties in Woodside Estates attract professionals and families seeking long-term holdings, and leasing demand for luxury homes remains robust—rental estimates for comparable inventory suggest strong monthly rates and institutional-level interest. For buyers, limited inventory and a stable pool of qualified purchasers make now an opportune time to acquire an architecturally significant property; for sellers, comparable pricing and brisk marketing timelines indicate favorable positioning. Prospective purchasers should verify well/septic and major systems, and consider that the unique lot and mid-century design offer upside through targeted modernization or landscape enhancement.
