New Construction in Northern Virginia: Loudoun vs. Fairfax vs. Prince William (And Where Buyers Actually Get Value)
By Chris Colgan · The Colgan Team, powered by PLACE at Real Brokerage · August 2026
22+ years selling Northern Virginia real estate, across Fairfax, Prince William, Loudoun, Arlington, and Fauquier counties.
Thousands of new homes are coming to Northern Virginia. Plenty of them look like great buys on the builder's website. Then you factor in the price, the lot, and what can legally get built on the other side of your fence — and the list gets a lot shorter.
I've been selling in this market for 22 years. Below is the honest comparison of new construction in Loudoun County, Fairfax County, and Prince William County — what it costs, what the real risk is in each one, and which community I'd point you to depending on the kind of buyer you are.
Prefer to watch? The full breakdown is on my YouTube channel — new Northern Virginia market videos every week.
The short version:
Loudoun. Best product, highest prices, biggest zoning risk. Buy west of Route 28 or don't buy new here.
Fairfax. Averages have crossed $1M. Herndon is the last real value pocket with Silver Line access.
Prince William. The most house and land per dollar in the region. Independent Hill and the Quartz District lead it.
The mistake most buyers make: falling in love with a floor plan and never checking what's approved behind the tree line.
By the numbers: new construction across the three counties
| County | Typical new-build range | The catch |
| Loudoun | High $600s–$1.5M+ | Data center adjacency and zoning risk |
| Fairfax | Upper $500s in Herndon, $5M+ in McLean | Average assessment now over $1M |
| Prince William | Mid $400s and up | Longer commute, active roadwork |

Loudoun County: the best new construction, and the biggest asterisk
Loudoun has some of the best new construction in Northern Virginia right now. It also has some of the highest prices in the region. There's a reason people call it "Cashburn."
What it costs. New construction is going up all over Ashburn, Aldie, and Leesburg. Larger single-family homes in Ashburn and Aldie run from the high $600s up past $1.5 million, and well into the multi-millions on the high end. Some new homes near Leesburg are now pushing the low $2 millions.
At those numbers you cannot just fall in love with the house. You have to know what's planned around it.
The data center question — the honest version
Loudoun has one of the largest data center footprints on earth. County records show more than 50 million square feet permitted, with tens of millions more square feet somewhere in the application pipeline. Individual buildings cover hundreds of thousands of square feet and run 24 hours a day.
What residents are actually complaining about
Constant mechanical hum, blocked views, and new transmission lines. Public hearings on transmission routing near neighborhoods have been packed. Search YouTube and you'll find a dozen creators standing in Ashburn cul-de-sacs holding decibel meters. It's going viral for a reason.
The part nobody posts about
A George Mason University analysis found that homes closer to data centers actually sold for more on average — most likely because those same homes sit closest to the highest-paying tech jobs in the region. Data center tax revenue also carries a meaningful share of Loudoun's budget, which holds residential property tax rates down.
Loudoun has also tightened the rules. New data centers now face public hearings instead of sailing through by-right approval, and projects within 500 feet of homes can't use the old fast track. The era of a data center showing up unannounced next to your backyard is largely over. That doesn't undo what's already approved.

Where I'd actually buy new in Loudoun
I wouldn't avoid Loudoun. I'd avoid the wrong lot in the wrong location.
For separation, look west of Route 28, where farmland, tree cover, and conservation easements create natural buffers you can't get inside the Route 28 data center corridor. Willowsford in Aldie is the clearest example — the community is wrapped in permanently preserved open space rather than industrial-zoned land. New homes there generally land between the $700s and the mid-$1 millions.
Belmont in Ashburn is another one I'd put on the list — established, grown-in, with mature landscaping instead of a construction staging yard. Leesburg still has pockets worth touring.
I currently have a client under contract on new construction in Aldie — a YouTube viewer, actually. Beautiful property, walking trails, small community. That deal works because of the lot, not just the elevation they picked.
Do this before you sign with any builder in Loudoun: pull the zoning map for every parcel touching the community and check what's already been approved. Not what's there today. What's approved.

Fairfax County: averages crossed $1 million — Herndon is the value play

In Fairfax the problem isn't zoning risk. It's the price spread from one ZIP code to the next.
The average assessed value of a single-family home in Fairfax County has crossed $1 million for the first time. Read that again — the average assessment. That's Malibu math in a county with a Costco on every corner. In McLean and Great Falls, an 8,000-square-foot new build starts around $5 million and climbs from there.
Why Herndon keeps making my list

Herndon gives buyers a genuine entry point into Fairfax County without giving up location, schools, or job access.
- Silver Line access. Herndon Station and Innovation Center are both right there.
- Dulles in 10 minutes. Not 40. Ten.
- The employers. Amazon Web Services, Northrop Grumman, General Dynamics, MITRE, and CACI all sit in the surrounding corridor.
- An actual downtown. Local restaurants, shops, a farmers market, and Friday Night Live all summer.
What new construction costs in Herndon. The range is wide, which is exactly why representation matters here. We just put a client under contract on a brand-new Drees townhome at $550,000 — after a $70,000 price reduction negotiated for a YouTube viewer. Those Drees townhomes generally run from the upper $500s into the $700s. Alpine Valley townhomes start in the mid-$700s and reach roughly $900,000. Luxury single-family can cross $2 million, which is right where a listing I just sold in Herndon closed.
That $2 million sale matters. It tells you high-end buyers are choosing Herndon on purpose — for the location and the lifestyle, not as a fallback.
More is coming, too. Hundreds of new homes, ground-floor retail, and walking paths straight to the Herndon Metro station are in the pipeline. Herndon is at an earlier stage of that transformation than Tysons or Reston, which is exactly why the value is still on the table.
One caution on schools: Herndon gives you Fairfax County Public Schools, but assigned schools shift by address — sometimes street by street. Verify the boundary for the specific lot before you write the contract, not after.

Herndon Townhomes
Prince William County: the most house and land per dollar
Prince William is a genuinely different market from Loudoun or Fairfax. You get more house, more land, and more for your money — and new construction usually starts below what buyers see in the other two counties.
The county's median sits in the low $600s, with detached homes averaging near $700,000. It's the best place left in Northern Virginia to buy real land without leaving the region. If space matters more to you than a 20-minute Metro ride, this is your county.
Independent Hill, Manassas — the family pick
Independent Hill by Ryan Homes is the community I'd send most families to right now. Townhomes start in the low-to-mid $600s and single-family homes start in the upper $800s.
The base price includes a gourmet kitchen with quartz counters, a finished rec room, a two-car garage, and the smart home package — features that are $40,000 in options at other builders.
The location does real work: direct access to Route 234, about 10 minutes to I-95, 15 minutes to Old Town Manassas, 20 minutes to Stonebridge at Potomac Town Center. George Hellwig Memorial Park is half a mile away. Prince William Forest Park is about 20 minutes out. Manassas Regional Airport and VRE service are both close.
And the schools: it's zoned for Charles J. Colgan Sr. High School — fully accredited, strong reputation, and home to an audition-based fine and performing arts academy that ranks among the best in Virginia. It's named after my grandfather, the late Virginia State Senator Charles J. Colgan Sr. Obviously the reputation is because of me and not him. Feel free to disagree in the comments.

Quartz District, Woodbridge — the first-time buyer pick
If you're a first-time buyer or you're buying primarily for investment value, this is the first place I'd take you.
The Quartz District sits at Prince William Parkway and Minnieville Road in Woodbridge, a few minutes from I-95. It's 145 acres of walkable, mixed-use development — more than 1,000 homes plus retail, office, and Prince William County's first Whole Foods. A walkable community in Prince William County is genuinely rare.
- Condos in the mid-$400s, townhomes starting in the mid-$500s
- Quartz counters and gourmet kitchens in the base price
- Rooftop terrace options — almost unheard of at this price point
- Builder incentives running up to roughly $22,000 toward closing costs
- Prince William County schools at all three levels within a few miles
A major grade-separated interchange is being built at that intersection right now, which is the whole reason the district is possible. I'll be straight with you: buying here in 2026 means living next to roadwork for a while. That's also exactly why the pricing is what it is.
Go deeper: The Quartz District Dossier covers the full development analysis, and this post breaks down what the Whole Foods and the interchange actually mean for your home's value.

4 mistakes that quietly destroy new-construction value
These are the ones I watch buyers make every single year.
- Ignoring the HOA math. Fees stack fast once pools, internet, trash, and community programming get bundled in. Get the current fee and the reserve study before you go under contract.
- Buying the wrong lot. That wooded view behind your deck is only yours if somebody owns it and can't build on it. Otherwise it's a future data center, a school, or 40 more townhomes.
- Skipping the zoning check. Pull the future commercial and industrial zoning for everything adjacent, especially anywhere near a substation or a Route 28 / Route 234 corridor parcel.
- Negotiating the wrong number. Builders protect the base price because it sets the comp for every remaining home in the phase. They will move on upgrades, closing costs, and rate buydowns. That's where the money is.
The verdict: which county wins for which buyer
There is no single community that wins for everybody. Each of these wins for a different reason.
| If you are… | Buy here | Entry price |
| A tech commuter who wants Silver Line access and walkability | Herndon (Fairfax) | Upper $500s |
| A family who wants space, included features, and a strong high school | Independent Hill (Prince William) | Low $600s |
| Focused on land, buffers, and long-term school funding | Willowsford / western Loudoun | $700s |
| A first-time buyer or value/investment buyer | Quartz District (Woodbridge) | Mid $400s |
Never walk into a builder's model home alone
This is the single most expensive mistake in new construction, and it costs buyers nothing to avoid.
That agent at the sales desk is a nice person. They also work for the builder. In most Northern Virginia communities, the builder pays a buyer's agent commission out of their marketing budget — meaning representation costs you nothing extra and gives you somebody negotiating the upgrade package, the closing cost credit, the lot premium, and the punch list on your side of the table.
The one rule: register with your agent before your first visit. Walk in unrepresented and most builders will lock you out of bringing one in later.
An agent who knows builder sales cycles knows when a phase needs to close out and when the incentives get real. That's how we got a $70,000 reduction on a Herndon townhome.
The bottom line
Loudoun gives you the best product at the highest price with the most homework required. Fairfax gives you the location premium, and Herndon is the last place you can buy into it without a $1 million entry ticket. Prince William gives you the most house, the most land, and the two communities I'd put a first-time buyer in today.
Find the one that fits your budget, your lifestyle, and where you're headed next. Get that right and you're not just buying new construction — you're making a smart move.
