Search "new construction homes McLean VA" this month and the results will not agree with each other. One listing shows a fully staked lot with demolition permits pending. Another shows a rendering for a home that will not exist until late 2028. A third shows a colonial from 1968 in Chesterbrook with a note about asbestos floor tile that needs to be abated before anyone can touch the kitchen. All three show up under the same search term. None of them are the same purchase.
That is not a filter problem Zillow or Redfin can fix. It reflects something true about how McLean actually builds right now. The label "new construction" covers three separate paths with three different price floors, three different timelines, and three different kinds of buyer standing at the closing table. A buyer who does not know which path they are actually shopping for will misjudge both the calendar and the check they need to write.
Path One: You Are Buying the Lot, Not the House
In much of McLean, the structure on a property is worth less than the ground under it. Older colonials and ramblers from the 1950s through the 1980s sit on quarter-acre and half-acre lots in established neighborhoods like Langley Forest, Franklin Park, Salona Village, and West McLean, and buyers are increasingly purchasing them for the land alone. The home comes down. A custom build somewhere between 5,000 and 11,000 square feet goes up in its place.
That process has a friction most search filters do not surface. Nearly every McLean home built before 1980 contains asbestos in some form, commonly 9-by-9 floor tile that was standard through the 1950s and 1960s. Before any demolition permit clears through Fairfax County, that material has to be inspected and, if present, professionally abated. A teardown project in the McLean Hamlet neighborhood recently ran through this exact sequence: a 4,200-square-foot mid-century colonial demolished and site-graded in three days, with a Fairfax County DEMOR permit coordinated ahead of time, clearing the way for an 8,200-square-foot replacement home. A separate project in Chesterbrook involved selective kitchen and bathroom demolition on a 1968 colonial, with asbestos tile inspection and abatement completed before the renovation contractor could mobilize.
None of that shows up in the sale price of the lot. It shows up afterward, in the calendar and the change orders.
The full economics of the rebuild path are steep even before ground breaks. A realistic 2026 custom project in McLean, roughly 5,200 square feet above grade plus a 1,800-square-foot finished basement, typically lands between $3.8 million and $4.5 million all-in once lot acquisition, demolition, design, permitting, construction, landscaping, and contingency are counted. Construction costs alone run $350 to $550 per square foot. From lot acquisition to occupancy permit, the full cycle usually takes 18 to 30 months: 4 to 6 months for design and engineering, 2 to 4 months for Fairfax County review, and 12 to 18 months for construction itself, depending on complexity and inspection scheduling.
That is why a buyer touring an "available now" teardown lot in McLean is not touring a house. They are touring a two-year commitment with a demolition permit as the first line item.
Path Two: The Last 25 Acres
McLean is nearly built out, which is what makes Knolewood unusual. The 24-lot subdivision is rising on 25 contiguous acres near the corner of Lewinsville Road and Lancia Drive, the last remaining undeveloped parcel of that size in McLean, according to reporting from FFXnow. The site plan was submitted to Fairfax County in December 2023, and county staff completed their review in September 2025. Lots range from 0.82 to 1.2 acres, laid out along wide tree-lined streets with sidewalks that end in two cul-de-sacs. Buyers work with one of three vetted local builders, Artisan Builders, Galileo Signature, or Winthrop Custom Homes, on a custom home built from scratch. The first section of the subdivision was on track to be paved by December, with the second section completed by February 2026.
This is the one true ground-up path in McLean right now. There is no existing structure to remove, no asbestos abatement to schedule, no demolition contractor to coordinate. A buyer picks a lot, picks a builder, and starts from a clean site plan that Fairfax County has already reviewed and approved. It is also, by definition, finite. Once the 24 lots sell, there is no comparable parcel behind it. McLean does not have another 25-acre assembly waiting in the wings.
Path Three: New, But Not Quite McLean
The third path carries the McLean name without sitting inside the neighborhood most buyers picture when they hear it. The Ritz-Carlton Residences, McLean, Tysons is a 102-unit standalone condominium building from developer Renaissance Centro, the same firm behind the Monarch tower that opened in Tysons in 2023. Units run from roughly 2,500 to 4,500 square feet, priced from about $1 million, with construction scheduled to begin in 2026 and completion targeted for late 2028. The building sits adjacent to the Ritz-Carlton Tysons Corner hotel and Tysons Galleria, with architecture by FXCollaborative and interiors by MAWD, and more than 15,000 square feet of amenities including a pool, spa, pet spa, theater room, and rooftop pickleball and padel courts.
The project's own developer has been direct about who it is built for. Renaissance Centro's leadership has pointed to strong demand from empty-nesters currently living on large lots in McLean and Great Falls who want to downsize without giving up scale, people ready to leave a five-acre yard behind but unwilling to compress into a 1,200-square-foot unit. For that buyer, the Tysons address is a feature, not a compromise: single-level living, hotel-style service, and a walk to Tysons Galleria in place of lawn maintenance. For a buyer who specifically wants a McLean street address and the Langley school pyramid, it is worth knowing upfront that this project sits in the Tysons corridor rather than inside McLean's residential core.
Three Paths at a Glance
| Teardown-Rebuild | Knolewood | Ritz-Carlton Residences | |
|---|---|---|---|
| What you're buying | An existing lot, then a demolition and custom build | A ground-up lot in a new 24-home subdivision | A branded condo unit in a tower under construction |
| Typical timeline | 18 to 30 months from purchase to occupancy | Custom build timeline per chosen builder | Completion targeted for late 2028 |
| Entry price point | $3.8M to $4.5M all-in for a mid-size custom home | Lot pricing not publicly disclosed as of the subdivision's late 2025 announcement | Starting around $1 million |
| Best suited for | Buyers who want a specific established neighborhood and are prepared to manage a build | Buyers who want ground-up new construction without a demolition step | Downsizers who want single-level luxury and hotel-style service |
Why the Market Is Sorting Itself This Way
The broader McLean market has been sending a consistent signal underneath all three of these paths. Median sales price surpassed $2 million in October 2025 even as the number of homes sold declined year over year and days on market lengthened, based on Redfin data reported by FFXnow. Buyers are still willing to pay top prices, but they are taking more time and applying higher standards, often passing on homes that feel dated or compromised.
That helps explain why the market has split into these three specific tracks rather than one blended "new construction" category. Each path is a different way of guaranteeing the buyer gets exactly what current demand is rewarding: the teardown path guarantees the location and lets the buyer control every finish, Knolewood guarantees a truly clean lot in a market where clean lots barely exist, and the Ritz-Carlton Residences guarantees new construction without any lot at all. A market that is punishing anything that needs work will naturally produce these three cleaner, more defined alternatives to the compromise of buying something older and hoping it ages well.
For anyone comparing raw price data across portals, this same bifurcation explains why the numbers look inconsistent from source to source. A list-price median measured in September 2026 sat near $1.72 million, while a closed-sale median for the three months ending in May 2026 ran closer to $1.9 million, and a broader home-value model placed the typical McLean home nearer $1.47 million during the same general period. Each of those figures is measuring a different slice of a market where a handful of high-value closings, teardown lots, or brand-new units can move the number by hundreds of thousands of dollars in a single month.
Frequently Asked Questions
If I buy a teardown candidate in McLean, can demolition start right away? Not until the property has been inspected for asbestos, since nearly every structure built before 1980 in McLean contains asbestos-containing material, and any abatement work has to clear before a Fairfax County demolition permit is issued.
Are lots still available at Knolewood? The subdivision's 24 lots were announced in November 2025 with construction on the first section targeted for completion by December and the second section by February 2026. Availability changes as builders sell through inventory, so current status is worth confirming directly.
Is the Ritz-Carlton Residences actually in McLean? The building sits in the Tysons corridor adjacent to the Ritz-Carlton Tysons Corner hotel and Tysons Galleria, carrying the McLean, Tysons name but not a McLean residential street address.
If you are weighing a teardown lot against Knolewood or a branded tower in Tysons, the math and the timeline are different enough that they deserve to be worked through side by side before you write an offer on any of them. Cristina Sison has spent years watching McLean's building cycles up close and can walk you through which path actually fits your timeline, your budget, and the neighborhood you have in mind.
