McLean's last 25-acre undeveloped parcel at the corner of Lewinsville Road and Lancia Drive is transforming into Knolewood McLean luxury homes, with 24 custom single-family estates set to redefine ultra-luxury living in this elite enclave. Acquired for $27 million in October 2024, the site—once home to an 1875 manor house, stables, and tennis courts—now features cleared land ready for wide, tree-lined streets ending in cul-de-sacs, with the first paving section complete by December 2025 and the second wrapping up this February 2026. As a top-producing agent in McLean, I've watched this McLean new development emerge as the pinnacle of McLean luxury real estate, drawing buyers who demand privacy, customization, and proximity to Langley High School and Tysons Corner.
Inside Knolewood: The Last Frontier for McLean Single-Family Homes
Knolewood stands out in McLean's saturated luxury scene by offering 24 estate-sized lots from 0.82 to 1.2 acres, the largest new opportunity in years amid tightening inventory. Homeowners partner with elite builders like Artisan Builders, Galileo Signature, or Winthrop Builders to craft bespoke McLean single-family homes, emphasizing modern luxury features such as spa-level primary suites, flexible bonus spaces for offices or gyms, and smart-home systems—all tailored to the DMV's discerning tastes. Three lots have already sold swiftly, signaling strong early demand in a market where McLean's median sale price hit $1.9 million in December 2025, down 12.8% year-over-year but with price per square foot up 17.9% to $520.[1][4]
This McLean new construction project preserves McLean's legacy of expansive living, just minutes from Great Falls Park's hiking trails and the buzz of Tysons Corner shopping. In my years selling Knolewood McLean luxury homes and nearby properties, I've seen how these oversized lots—rare in a community with no remaining greenfield sites—appeal to families prioritizing Langley High School's top-rated education and low-density neighborhoods. Paving progress as of February 2026 positions the first homes for groundbreaking soon, outpacing typical McLean new development timelines.
Why Knolewood Excels in Today's McLean Luxury Real Estate Market
McLean's housing data underscores Knolewood's timing: average home values reached $1,415,468 by late 2025, up 1.7% year-over-year, with homes going pending in about 29 days per Zillow metrics—faster than the 42 days Redfin reports for broader sales.[2][4] Yet luxury segments like this thrive, as detached McLean single-family homes command premiums near $1.18 million on average in Fairfax County, buoyed by stable demand despite rising days on market from 17 to 21 countywide.[6][7] Knolewood's no-HOA structure—unlike many McLean enclaves—offers buyers freedom to design without monthly fees, a key draw for custom builds starting well above the area's $1.9 million median.
Positioned at 8700 Lewinsville Road, it's walkable to McLean staples while delivering estate privacy, much like the modern luxury homes I've listed nearby that sold with features mirroring Knolewood's: zoned HVAC, rainfall showers, and multigenerational layouts. For buyers eyeing McLean luxury real estate, this development's scarcity—McLean's final major undeveloped parcel—mirrors the tightness driving Fairfax County's 2.97% average sold price increase to $883,520.[7] Dixie Rapuano clients often compare it favorably to Tysons Corner condos, trading density for acreage.
Custom Builds at Knolewood: Builders, Features, and Price Potential
Select from three vetted builders for your Knolewood McLean luxury homes, each specializing in transitional and modern designs suited to McLean's wooded aesthetic—think clean lines, abundant natural light, and seamless indoor-outdoor flow. Lots support homes with 7+ bedrooms, 6+ baths, and 8,000+ square feet, aligning with recent McLean comps like a $3.28 million sale at 1465 Mayhurst Boulevard boasting 8,220 square feet.[2] Without public pricing yet, expect lot premiums reflecting McLean's 8.9% ZIP 22101 value surge to $1,645,334 averages, positioning finished estates northward of $4-6 million based on custom precedents I've handled.[6]
These McLean new construction homes emphasize livability: boutique closets, app-controlled security, and bonus rooms that adapt from play areas to guest suites—trends I've negotiated into contracts for Langley High School-zone buyers. Near Great Falls Park, residents gain easy access to 800+ acres of trails, enhancing the outdoor lifestyle that defines McLean over denser Northern Virginia spots.
McLean Market Snapshot: How Knolewood Fits February 2026 Trends
As of February 2026, McLean's market shows resilience with 41 homes sold in December 2025 (down slightly from 45 YoY) but homes selling 2% below list after 46 days on average, per Redfin's competitive score.[4] Inventory constraints favor new projects like Knolewood, where McLean luxury real estate outperforms: Northern Virginia medians climbed 2.1% to $715,000, with single-family detached homes leading at $1.18 million.[7][8] In my experience touring buyers through McLean, McLean new development like this accelerates decisions, especially versus older McLean single-family homes lingering longer amid 12.8% median price dips.

The Strategic Edge of Buying into Knolewood McLean Luxury Homes
Knolewood buyers gain from Fairfax County's top schools, including Langley High School's consistent national rankings, and proximity to Tysons Corner's dining and retail—ideal for execs commuting to D.C. Without HOA dues, ownership costs stay lean, contrasting communities with $500+ annual fees I've seen deter luxury shoppers. As Dixie Rapuano, I've closed deals on comparable McLean estates where custom elements boosted values 15-20% post-build, outstripping the area's 1.7% overall appreciation.[2]
This McLean new development arrives as buyers pivot from Arlington's walkability to McLean's lots, per trends in my client consultations. For more on premium Northern Virginia options, see first-time home buyer guide for Northern Virginia—even luxury seekers start there.
