Home Additions · Centreville, VA
You've been putting on makeup in the hallway for eleven years because the primary bath has one small vanity. The kitchen sits behind the load-bearing wall. Your mother asks about visiting for three weeks in May and there's no ground-floor bedroom for her. A bigger colonial in the same school pyramid runs three or four hundred thousand more than the addition costs.
The Centreville Addition Project
You come around the rear and see what the parcel actually gives. Most Centreville lots run shallow before they hit the coverage cap, so the addition either lands as a modest rear bump-out or lifts up over the garage as a second story. The primary suite upstairs is undersized. The kitchen is closed off. No mudroom off the garage.
The husband and wife stand in the rear yard with Alex and the plat on the second walkthrough. The impervious-surface cap is already close from the driveway and patio. The rear setback runs to twenty-five feet. The addition either builds up over the garage, adds a smaller side footprint, or takes the existing screened porch as scope. Alex sketches all three against the lot lines and the household picks the one that reads right against the block.
The new primary suite has a real walk-in closet and a shower that reads at the finish tier of the kitchen you did four years ago. The bedroom over the garage is the teenager's, and she stopped asking for her own bathroom because she has one now. Your mother has the first-floor guest suite with the private entry, and she comes home from her walk without needing anyone to open the front door for her.
What Centreville Homeowners Are Solving For
The Centreville households we hear from have almost all outgrown the original colonial floor plan. Kids added a bedroom, parents added an in-law scope, or the primary bath that used to work stopped working. The walkthrough turns into a list of what the household is actually solving for.
One vanity, no walk-in closet, and the same tub-shower surround that came with the house. I have been putting on makeup in the hallway for eleven years.
The original Centreville primary bath was sized before walk-in closets and separate showers were standard. The addition rebuilds the whole suite: rear bump-out for a real bath, walk-in shower and a soaking tub, real closet.
Ask yourself
Would the addition extend the existing primary or build the new suite above it? The answer usually turns on how the roof line reads against the neighbors' elevations.
Every gathering we host runs across two rooms and one wall. The wall has to go.
The load-bearing wall between kitchen and family room shows up in almost every Centreville addition conversation, even when the addition is elsewhere. Kitchen bump-out adds counter and gives the beam an easier path. The wall comes down as ride-along scope on the addition permit stack.
Ask yourself
Should the kitchen bump-out ride along with the primary suite scope, or wait a phase? Bundling shares the crew rotation and permit calendar.
Mom is coming in April for a month. Long-term after that. We have four bedrooms upstairs and none of them work for her.
First-floor in-law scope is one of the most common Centreville addition triggers. A rear-elevation bump-out on the ground floor holds a bedroom with a real closet, a full bath with a walk-in shower, and (where terrain allows) a private entry. Level access from the driveway or the front walk. She keeps her mornings, and the household keeps its upstairs.
Ask yourself
Does the household want the suite as a permanent addition, or a flexible one that later reads as a home office or guest room? The finish specs shift with that.
Our third and fourth kids are in the same bedroom and they are almost too old for that. We're not moving. We need another bedroom.
Growing families in the four-bedroom Centreville colonial run out of bedrooms. When the lot won't support a rear addition, the second-story-over-the-garage answer usually holds two more bedrooms plus a shared bath, or one bedroom plus a bonus room the household later turns into a home office. The footprint stays the same, the roof line changes, and the household stops re-shuffling bedrooms every fall.
Ask yourself
How long does the household plan to need the extra bedrooms? Ten-year horizon supports the second-story build; three-year horizon usually points at a smaller side-elevation bump-out.
The colonial two neighborhoods over sold at seven-fifty last month. We paid four for this one. We're not writing that check.
The Centreville household on a locked-in mortgage rate hits the trade-up math and stops. A comparable colonial in the same school pyramid runs three or four hundred thousand more, and the addition costs a fraction of that. Same neighbors, same tree cover the kids grew up under.
Ask yourself
How does the finished-home value compare to the neighborhood comp after the addition? Over-improving the block usually doesn't return.
How It Works in Centreville
The concrete parts of a Centreville addition: the Fairfax County permit stack, the six-ARB HOA landscape that reviews every exterior scope, the setback and lot-coverage read that decides build-out vs build-up, the foundation and roof-tie scope, and what a Centreville addition actually costs across the tier range.
Step 01
An addition project pulls the full permit stack: structural, plumbing, electrical, mechanical, sometimes zoning variance and grading, all filed through the Fairfax County Land Development Services. Residential plan review typically runs three to six weeks. Reviewers include Zoning for setbacks and coverage, Building for framing and structural, Site for grading and drainage, the Fire Marshal for egress and separation, and Wastewater for any plumbing scope. We file the full package as one submission and coordinate the trade sub-permits so the crew is never sitting on paperwork.
Step 02
Additions always trigger HOA architectural review in Centreville — Little Rocky Run, Virginia Run, Compton Village, Faircrest, Sully Station, and Newgate each run an active ARB with distinct submission requirements and meeting schedules. The working order is HOA architectural review FIRST, then county permit. We submit the ARB packet with elevation drawings, materials specs, and site plan before the county drawings finalize, wait for the association's decision in writing, then file with the county. Skipping this order is the fastest way to have county-approved plans that the HOA rejects.
Step 03
Fairfax County R-3 zoning (the Centreville planned-community default) puts front setbacks at 30 feet, side at 12, rear at 25, with impervious-surface caps at 35% of lot area. Many Centreville parcels are already close to the coverage cap from the original driveway, patio, and rear walkway. That's why second-story additions are common here: they add square footage without adding footprint. The walkthrough always includes a plat read against the setbacks and coverage cap before the design phase starts. Where the parcel can support rear scope, we build out. Where it can't, we build up.
Step 04
Second-story additions in Centreville tie back to the existing roof line at a seam the ARB will read. Roof pitch has to match, ridge height has to align, and shingle color has to blend where the new roof meets the old. Ridge-vent geometry, valley details, and gutter transitions all get designed against how the elevation reads from the street. The framer and roofer work together at the seam, and the HOA reviews the elevation drawings before the county drawings finalize.
Step 05
A bump-out addition (small footprint growth — kitchen bump-out to open the wall, mudroom off the garage, or a sunroom on the rear elevation (up to ~200 sq ft)) runs $85K–$140K and finishes in three to four months. A full room addition (full room addition — rear family room, primary suite bump-out with walk-in closet and full bath, in-law suite with private entry, or four-season sunroom (200–800 sq ft)) runs $140K–$275K and lands at four to six months on-site. A signature addition (second-story addition over the garage or the main-level footprint, full multi-generational wing with kitchenette, or attached ADU — the biggest structural bet short of a whole-home rebuild) runs $275K–$500K+ and takes six to ten months. Design plus permit adds four to eight weeks plus two to six weeks at Fairfax County plus two to four weeks at the HOA (running in sequence, ARB first) on the front end. Every proposal is fixed-price after the walkthrough.
11+ Years in Centreville
Alex still handles most Centreville first-walks himself. The shop is on Kendra Way, ten minutes from Sully Station, Virginia Run, and Newgate. Eleven years of Centreville additions means we know which parcels have already hit the coverage cap, which ARBs read a two-story elevation cleanly, and where the load-bearing wall in the original floor plan sits before we've measured it.
Across Centreville
A Sully Station second-story addition looks different from a Virginia Run primary suite bump-out or a Little Rocky Run coverage-capped side scope. The parcel and the ARB shape what's possible across every Centreville neighborhood.
The Sully Station second-story addition over the garage.
What you have
A mid-nineties Sully Station colonial with a shallow rear yard already close to the county coverage cap. Four bedrooms upstairs sized to 1990s standards, primary bath without a walk-in closet, kitchen closed off from the family room. The household has outgrown the bedroom count.
What you're asking for
Two bedrooms plus a bath added over the garage, roof-line matched to the original elevation, and Sully Station ARB packet filed before the county drawings finalize. Kitchen bump-out with the load-bearing wall coming down as ride-along scope.
The larger Virginia Run parcel, primary suite scope on the rear.
What you have
One of the larger Virginia Run colonials with real rear-yard depth. Primary bath from 1994 with no walk-in closet, single vanity, tub-shower surround. Household in place for fifteen-plus years and planning to stay.
What you're asking for

What you're asking for
First-floor in-law scope: bedroom with real closet, full bath with walk-in shower, private entry from the driveway side, level access throughout. Kitchen bump-out where the scope also needs a mudroom off the garage. Centre Ridge ARB packet on the exterior scope.
The 1980s London Towne parcel, coverage cap forces up.
What you have
An early-1980s London Towne colonial on a smaller parcel where the coverage cap is already tight from the original driveway and patio. No room for a rear ground-floor addition without variance.
What you're asking for
Second-story bedroom addition above the existing primary suite footprint. Two bedrooms plus a shared bath. Roof-line and ridge height engineered to sit cleanly against the London Towne elevation pattern. ARB packet with elevation drawings filed before the county.
The Newgate colonial, statement primary suite scope.
What you have
A mid-nineties Newgate colonial at the larger end of the neighborhood. Two-story family room already present, oversized primary suite footprint, but the primary bath and closet are sized to 1994 standards. Household spends money and the block finishes support it.

What you're asking for
A modest side-elevation bump-out where the setback allows, or a second-story addition above the existing primary suite that stays inside the coverage cap. Faircrest ARB packet with careful elevation match to the townhouse row.
The Compton Village bump-out, kitchen and primary paired.
What you have
An eighties or nineties Compton Village colonial. Primary suite and kitchen both due for scope changes. Rear yard shallow but supports a modest addition to the primary suite. The household wants to bundle rather than sequence.
What you're asking for
A paired scope: primary-suite rear bump-out with walk-in shower and closet, plus a kitchen bump-out with the load-bearing wall coming down. One permit stack, one crew rotation, one dust-containment window. Compton Village ARB packet on both elevations.

The finished addition matters. So does everything before it: the months we spend in someone’s home, the questions we answer at nine at night, the calls we return the same day. These are the words of people who lived that with us. The experience is the work.
Centreville Additions FAQ
Setbacks and coverage caps, the six-ARB review calendar, build-out versus build-up, roof-tie details, HVAC and panel scope. Centreville-specific questions before signing.
Yes. Additions carry the biggest permit stack of any residential scope — structural, plumbing, electrical, mechanical, sometimes zoning variance and grading. Every one gets filed through the Fairfax County Land Development Services, coordinated across trades, and inspected before the walls close. Plan review typically runs three to six weeks. The full paperwork sits in the handover binder — nothing waits on the homeowner to chase.
Yes, always. Centreville's HOA review boards — Little Rocky Run, Virginia Run, Compton Village, Faircrest, Sully Station, and Newgate — read every addition against exterior visibility, elevation match, materials, and (on some boards) even the roof pitch of the new work. The working order is ARB review FIRST, county permit SECOND. We submit the ARB packet with elevation drawings, material specs, and site plan before the county drawings finalize. Timeline is usually two to four weeks at the ARB, sometimes longer if the meeting schedule forces a defer. Skipping this order can leave county-approved plans that the HOA won't approve.
A bump-out addition (kitchen bump-out, mudroom, small side scope) runs $85K–$140K and finishes in three to four months. A full room addition (rear family room, primary suite bump-out with full bath, in-law suite, four-season sunroom) runs $140K–$275K and lands at four to six months on-site. A signature addition (second-story over the garage or main-level footprint, multi-generational wing, attached ADU) runs $275K–$500K+ and takes six to ten months. Every proposal is fixed-price after the walkthrough.
The plat decides. R-3 zoning puts front setbacks at 30 feet, side at 12, rear at 25, with impervious-surface caps at 35% of lot area. Many Centreville parcels are already close to the coverage cap from the original driveway and patio. Where the parcel can support rear scope, we build out — usually a room addition or a primary-suite bump-out. Where the coverage cap or rear-yard depth won't support it, we build up — most often a second-story addition over the garage. The walkthrough always includes a plat read before design starts.
Working order is HOA architectural review FIRST, county permit SECOND. Little Rocky Run, Virginia Run, Compton Village, Faircrest, Sully Station, and Newgate each run their own ARB with distinct submission requirements and meeting schedules — usually monthly. We submit the ARB packet with elevation drawings, materials specs, and site plan before the county drawings finalize. Once the ARB approves in writing, we file with Fairfax County. Timeline is usually two to four weeks at the ARB; the county's plan review adds two to six more.
Usually yes, with a plan. The existing envelope stays sealed while the addition foundation and framing go up separate from the house. The disruption window lands when the addition ties into the existing house — the wall or roof-line opening between old and new is usually a two-to-four-week focused phase, and we schedule it against the household's calendar. Dust containment stays sealed at the tie-in, and the site broom-cleans daily. A primary-suite addition where the household's only shower is the current primary bath is the hardest live-through call — we sometimes stage the finish sequence so the shower window compresses to a few days.
