Home Additions · Burke, VA
The rear deck is showing every year of pressure-treated life. The kids came and went and the primary suite never got the walk-in closet it needed. Your mother is asking about visiting more often as she gets older. Twenty-two years into the same Burke Centre Colonial, the addition is the last major piece of the house you kept.
The Burke Addition Project
You walk out onto the rear deck and can feel the framing flex where the household has been walking on it for twenty-five years. The primary suite upstairs is the primary suite from the original build. The kitchen sits behind the load-bearing wall on the older Kings Park West and Signal Hill parcels, or reads more open on the Burke Centre-era Colonials. Wooded rear lots on parcels backing to Burke Lake give the addition somewhere natural to sit.
Alex meets the household on the deck on the second walkthrough. He reads the framing for code compliance, checks the roof line for tie-in geometry, and pulls the plat against the rear setback. Where the deck is past service life, the four-season conversion starts with full replacement rather than an overlay. Where the parcel supports a real wing, the design shifts from porch conversion to primary-suite or in-law scope.
The four-season room off the rear reads like part of the house year-round now — low-E glazing on three sides, low-slope ceiling, dedicated mini-split running quiet on both a January morning and an August afternoon. Or the new primary suite has a walk-in closet, a real shower, and finish that matches the kitchen the household did a decade ago. Or the first-floor in-law wing holds your mother when she visits, and eventually when she stays. Twenty-two years of being in place finally has the room that reflects it.
What Burke Homeowners Are Solving For
The Burke households we hear from have almost all been in the same house since the youngest was in strollers at Lake Braddock. The rest of the house has been renovated one room at a time. The addition is the specific room the household still doesn't have, or the aged rear deck that's finally becoming real living space. The walkthrough surfaces which one.
We built the deck the second summer we owned the house. It's now our third or fourth pressure-treated resurface. It's time to close it in.
Burke's rear-deck-to-four-season conversion is one of the most common addition patterns we run. Framing rebuilt to real footings, insulated walls with low-E glazing on three sides, a dedicated mini-split for HVAC, and the room reads as usable January-through-August. The porch stops being seasonal storage and becomes real square footage the household actually uses.
Ask yourself
Is the deck replaced fully as a four-season room, or does part of it stay open as a porch or grill area? Both work — the household lifestyle decides which.
We did the kitchen eleven years ago and the powder room last winter. Our primary bath is still the one that came with the house. It's the last room I keep the door closed on.
Burke long-tenure households often solve every room except the primary suite before they finally build the primary-suite addition. Rear-elevation bump-out with a real bath, dressing room or walk-in closet, and finish that matches the anchor rooms the household has been solving for twenty years. The suite finally reads as part of the same house the rest of the finish already did.
Ask yourself
Should the primary bedroom itself move into the new footprint, or stay in the existing bedroom and the bath expand into the addition? The household's furniture and bedroom orientation usually decide.
Mom drove herself to Christmas the last three years. This year my brother is bringing her, and she asked about staying a month.
The Burke first-floor in-law scope has real accessibility weight because the parent's timeline is usually already visible. Bedroom on the ground floor with a real closet, full bath sized with a no-curb shower and grab-bar blocking, and (where the wooded rear supports it) a private entry off the flagstone walk. She keeps her mornings, and the household keeps its own routine when she's here.
Ask yourself
Is this an addition for a parent moving in eventually, or one for extended visits over the next decade? The accessibility details are the same; the private-entry scope shifts.
The oldest is home from William and Mary with two friends. The youngest is at Robinson with her boyfriend downstairs. The couch is somebody's bed until Sunday.
Adding rooms above the existing footprint lets the Burke household hold the visitors without giving up rear yard. Second-story addition over the garage or over the primary wing, two bedrooms plus a shared bath, roof-line engineered to the existing pitch. The ARC packet with elevation drawings files alongside the design phase.
Ask yourself
How permanent are the extra bedrooms — visitor scope or eventual multi-generational? The framing plan and the finish tier both shift.
The electrician mentioned aluminum wiring in one of the bedroom circuits last time he was here. When we open the walls for the addition, are we going to have to deal with that?
Kings Park West, Signal Hill, and older Cherry Run parcels carry aluminum branch wiring on isolated circuits. When the addition load touches an aluminum circuit — new bathroom, new HVAC branch, new kitchen scope — it has to be addressed. COPALUM connectors at every junction is Fairfax County's approved remediation; full copper replacement is the alternative. Priced separately on the proposal so the household sees the actual number.
Ask yourself
Was the household's original inspection report clear on aluminum wiring, or was it a plumber's or handyman's later observation? An aluminum survey at the walkthrough removes the question.
How It Works in Burke
The concrete parts of a Burke addition: the Fairfax County permit stack, the Burke Centre ARC or subdivision-ARB review calendar, the deck-framing read for four-season conversions, the aluminum-wiring survey on older pockets, and what a long-tenure Burke addition actually costs at the finish tier the anchor rooms already set.
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 Burke — Burke Centre, Kings Park West, Timarron Cove, Longwood Knolls, Signal Hill, and South Run 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
Burke rear decks from the 1990s and early 2000s were built to code at the time, but most don't meet current frost-footing requirements for a conditioned enclosure. The four-season conversion starts with a framing read: joist and ledger condition, footing depth, ledger-flashing detail. Where any of those fail current code, the deck gets rebuilt on new footings before the enclosure goes up. Overlaying a four-season assembly on a deck that won't hold it is the fastest way to fail inspection and eat the cost.
Step 04
Kings Park West, Signal Hill, and older Cherry Run pockets in Burke carry aluminum branch wiring on isolated circuits. When the addition's finished-load package (new bathroom, sub-panel, HVAC branch, kitchen scope) touches an aluminum circuit, remediation is real scope. COPALUM connectors at every junction is Fairfax County's approved approach; full copper replacement is the alternative. We run the survey at the first walkthrough on any pre-1985 Burke house so the scope conversation reflects what's in the walls.
Step 05
A bump-out addition (kitchen bump-out, bathroom extension, mudroom, or a screened-porch conversion to a four-season room (up to ~225 sq ft)) runs $85K–$140K and finishes in three to four months. A full room addition (rear family room, primary suite bump-out with walk-in closet and full bath, first-floor in-law suite, four-season sunroom with low-E glazing and mini-split HVAC, or a paired kitchen-and-family-room extension (225–850 sq ft)) runs $140K–$285K and lands at four to six months on-site. A signature addition (second-story addition over the garage or main-level footprint, full multi-generational wing with kitchenette and separate entry, or a signature primary-suite wing on wooded parcels backing to Burke Lake or park land) runs $285K–$525K+ and takes six to ten months. Design plus permit adds four to eight weeks plus three to six weeks at Fairfax County plus two to four weeks at the Burke Centre ARC or other subdivision ARB on the front end. Every proposal is fixed-price after the walkthrough.
11+ Years in Burke
The Burke households we work for have almost all been in place through three principals at the local schools. Eleven years of Burke addition work means we know when the rear deck framing is past service life, which pockets carry aluminum branch wiring the addition load will touch, and how the Burke Centre ARC reads a two-story elevation against the block.
Across Burke
A Burke Centre four-season conversion reads different from a Kings Park West aluminum-wiring-heavy scope or a wooded South Run wing addition. Housing eras and ARC pattern shift across the pockets.
The Burke Centre Colonial, rear-deck four-season conversion.
What you have
A Burke Centre 1988–1993 Colonial with an aging pressure-treated rear deck from the original build or an early owner. Household in place fifteen-plus years, kitchen already done, primary bath done, deck is the last exterior element to solve.
What you're asking for
Four-season conversion on the deck footprint: new footings to code, insulated walls with low-E glazing on three sides, dedicated mini-split HVAC, ceiling detail that reads as part of the house. Burke Centre ARC packet on the elevation before the county drawings finalize.
The Burke Station Square parcel, paired kitchen and family room.
What you have
A Burke Station Square single-family from the late 1980s or 1990s. Kitchen behind the load-bearing wall, family room next to it. Rear yard supports a paired bump-out. Household hosts extended family regularly.
What you're asking for
Paired scope: kitchen bump-out with the load-bearing wall coming down, family room extended out onto the rear elevation, the two rooms reading as one hosting-scale volume. Coordinated crew rotation and shared permit stack.
The Cherry Run 1980s Colonial, forever-home primary suite.
What you have
A Cherry Run 1980s Colonial where the household has been in place through three principal changes at the elementary school. Rest of the house already renovated. Primary suite still original.
What you're asking for
A rear-elevation primary suite bump-out at forever-home finish tier: walk-in closet, spa-tier bathroom with soaking tub, dressing room, redrawn primary bedroom. Same trim and floor spec as the anchor rooms already done inside the house.
The Fox Lair parcel, first-floor in-law with private entry.
What you have
A Fox Lair Colonial with an aging parent moving in scheduled for the fall. Wooded parcel backing to a natural buffer, existing walkout on some parcels, standard ceiling, bathroom rough-in variable.
What you're asking for
First-floor in-law scope on the rear or side elevation: bedroom with real closet, accessibility-sized full bath, kitchenette with cooktop and fridge, and (where the parcel supports it) a private entry from the wooded rear. Fox Lair ARC packet on the exterior work.
The 1970s Kings Park West parcel, aluminum survey first.
What you have
A 1970s Kings Park West single-family. Tighter ceiling clearance than Burke Centre-era Colonials, aluminum branch wiring on isolated circuits, older 100-amp panel at capacity, no rear-deck starting condition.
What you're asking for
Systems-first approach with the addition: aluminum-wiring survey and COPALUM remediation where the addition load touches it, panel upgrade to 200 or 400 amps, sub-panel for the addition circuits. Then the addition scope — rear primary-suite bump-out or a modest side-elevation extension, sized against the tighter footprint.
The Timarron Cove Colonial, second-story bedroom count.
What you have
A Timarron Cove 1990s Colonial where the household has run out of upstairs bedrooms as the college kids keep coming home with friends. Rear yard shallow, panel with room for a sub-panel, roof line supports a pop-top.
What you're asking for
Second-story addition over the existing primary-suite footprint or over the garage. Two bedrooms plus a shared bath, or a primary-suite move upstairs. Roof-line matched to the existing elevation. Timarron Cove ARC packet with elevation drawings.
The wooded South Run parcel, rear wing addition.
What you have
A South Run single-family on a parcel that backs to park land or wooded acreage. Existing rear deck aging out, generous rear-yard depth, mature-tree canopy near the exterior wall, bathroom rough-in usually present.
What you're asking for
A rear wing addition that treats the wooded rear as part of the design: primary suite with dual walk-in closets, spa bath, and a screened-porch or four-season conversion off the corner. Mature-tree protection plan for any exterior scope. South Run ARC packet on the elevation and any tree removal.

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.
Burke Additions FAQ
The Fairfax County permit stack, Burke Centre ARC review, deck-framing reads for four-season conversions, aluminum-wiring survey on older pockets, and finish-tier realism at the long-tenure Burke household's forever-home level. Burke-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. Burke's HOA review boards — Burke Centre, Kings Park West, Timarron Cove, Longwood Knolls, Signal Hill, and South Run — 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, bathroom extension, or a screened-porch conversion — runs $85K–$140K and finishes in three to four months. A full room addition — rear primary suite, in-law suite, four-season sunroom, or paired kitchen-family bump-out — runs $140K–$285K and lands at four to six months on-site. A signature addition — second-story over the garage, full multi-generational wing, or a signature primary suite on a wooded parcel — runs $285K–$525K+ and takes six to nine months. Every proposal is fixed-price after the walkthrough.
Depends on the deck. Burke rear decks from the 1990s and early 2000s were built to code at the time, but most don't meet current frost-footing requirements for a conditioned enclosure. We read the deck framing at the walkthrough — joist condition, footing depth, ledger flashing. Where the framing meets current standards, an enclosure overlay is workable. Where it doesn't, the four-season conversion starts with a full rebuild on new footings before the enclosure goes up. Overlaying a four-season assembly on a deck that won't hold it fails inspection.
Kings Park West, Signal Hill, and older Cherry Run pockets in Burke carry aluminum branch wiring on isolated circuits. We run the survey at the walkthrough on any pre-1985 Burke house. When the addition's finished-load package touches an aluminum circuit — new bathroom, sub-panel, HVAC branch, kitchen scope — it has to be addressed. COPALUM connectors at every junction is Fairfax County's approved remediation; full copper replacement is the alternative. Either way, it gets priced as its own scope on the proposal.
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.
