Infill New‑Builds in Hollin Hall/Wellington: A Builder Guide

Thinking about replacing a tired cottage in Hollin Hall or Wellington with a new custom home? Infill building in Fort Hunt can be rewarding, but it moves faster and cleaner when you know the local rules, the right sequence, and what buyers here will pay a premium to own. You want a clear roadmap that minimizes surprises, stays neighbor-friendly, and produces a floor plan and finish package that sells well now and on resale.

This guide gives you a step-by-step process for Fairfax County permitting, lot selection, demolition logistics, construction touchpoints, buyer-preferred layouts and features, timeline ranges, and risk controls specific to Fort Hunt’s Hollin Hall and Wellington neighborhoods. Let’s dive in.

Fairfax County infill basics

Fairfax County uses a defined set of agencies and online systems for infill new builds. Getting your arms around who does what will save weeks.

• Land Development Services and Planning and Development handle zoning interpretations, site development, grading, erosion and sediment control, and building permits. You will work through the county’s online permit portal for plan submissions, reviewer comments, payments, and inspections.
• The Zoning Ordinance and county GIS parcel tools confirm your zoning district, setbacks, height, coverage, and any need for lot consolidation or variances.
• Department of Public Works and Environmental Services reviews stormwater management and drainage.
• Virginia Department of Transportation gets involved for driveways or any work within a state right of way.
• The Health Department reviews only if a lot relies on a private well or septic. Many Fort Hunt parcels are on public water and sewer, but verify per parcel.
• Utilities include Dominion Energy, Washington Gas, and Fairfax Water. Each has its own service connection process.
• The Virginia Department of Historic Resources may be relevant if the structure or lot is in a historic district or contains resources.
• FEMA floodplain mapping is a must for lots near the Potomac or in low-lying areas.

Permitting path and ePermitting

You can shorten your schedule by front-loading the right steps and submitting strategically.

Pre-application and due diligence

• Confirm zoning, setbacks, coverage, and allowable height.
• Check sewer and water availability and utility connection requirements.
• Review floodplain maps and any wetlands buffers.
• Identify tree conservation constraints and canopy requirements.
• Consider a pre-application meeting with county staff to confirm submittal requirements and sequence.

Site plans and adjustments

• If you need a minor subdivision, lot consolidation, or boundary adjustment, expect a land development review. Build this into your calendar early.

Grading and erosion control

• Secure erosion and sediment control approvals before demolition or major earthwork. Install controls before you disturb soil.

Demolition permit and abatement

• Obtain demo permits, utility disconnects, and any required hazardous materials abatement documentation.

Building permits and reviews

• Submit architectural, structural, and MEP plans via the county’s online portal. Where allowed, submit zoning/site and building packages concurrently to reduce sequential delays. Expect multiple review cycles.

Inspections and CO

• Plan for inspections at erosion control, foundation, framing and rough-ins, insulation and energy tests, and final. A Certificate of Occupancy closes the loop.

Lot selection in Hollin Hall and Wellington

The right lot choice in Fort Hunt protects your budget and your resale.

Zoning and buildable area

• Confirm the exact zoning district and setback envelope. Map buildable area after setbacks, easements, and required yards. Verify height and coverage limits and rules for accessory structures.

Topography and soils

• Slope affects foundation type, retaining walls, stormwater controls, driveway design, and cost. Document contours and plan accordingly. Commission a geotechnical investigation to check for clay, rock, or high water tables.

Trees, floodplain, and utilities

• Mature canopy is common and valued locally. Tree preservation and replacement standards can shift your footprint or add cost.
• Parcels near the Potomac or low areas may touch regulated floodplain or wetlands buffers. Check FEMA and county maps early.
• Verify public water and sewer service and any unusual connection requirements. Septic or well approval paths are longer and site-specific.

Red flags that derail infill

• Heavy grading needed to create a flat pad.
• Large protected trees within the target footprint.
• Location in the FEMA 100-year floodplain or adjacent to wetlands.
• No public sewer or water, or high connection costs.
• Neighborhood covenants or design review restrictions that limit your exterior choices.

Demolition and construction logistics

Good site etiquette and compliance keep projects moving and neighbors supportive.

Pre-demo requirements

• Order a hazardous materials survey for older structures. Asbestos and lead-based paint often trigger abatement by licensed contractors.
• Secure electric, gas, water, and telecom disconnects and related permits before demolition.
• Install erosion and sediment controls and hold the required inspection.
• Submit a demolition plan that addresses dust, noise, traffic, and disposal. Salvage reusable materials where feasible.

Site setup and neighborhood impact

• Plan off-street staging and storage to keep curbs clear. Coordinate any temporary lane closures or large deliveries with the county.
• Establish truck routes that avoid narrow residential blocks.
• Install fencing and maintain erosion controls per county standards.
• Arrange worker parking policies or off-site options to reduce congestion.
• Communicate schedules for noisy operations in advance. Follow local hours-of-operation rules.

Floor plans that sell in Fort Hunt

Local buyers often replace smaller homes with modern, flexible layouts that capture light and connect to the outdoors. Proximity to the George Washington Parkway, the Potomac, and regional job centers supports demand for thoughtful, comfortable living.

Size and layout targets

• Finished living area often falls in the 2,200 to 3,800 square foot range. Offer both right-sized plans at 2,200 to 2,800 square feet and move-up plans above 3,000 square feet.
• Provide 3 to 5 bedrooms and 2.5 to 4 or more baths depending on size. A main-level primary suite is highly marketable and supports aging in place.

Kitchen, storage, and flex spaces

• Open sightlines with a large island, dining and family room flow, and a casual eating area perform well.
• Include a walk-in pantry, stone or quartz counters, and a 36 to 48 inch professional-style range or an induction cooktop.
• Deliver a true home office or a flex guest suite that can double as an office.
• A mudroom or drop zone near the garage with adjacent laundry resonates with families.

Basements, garages, and indoor-outdoor flow

• A finished basement with daylight windows adds high-utility space for recreation, a guest suite, and storage.
• A two-car garage is the norm, with side-load or rear-load orientation preferred for curb appeal. Include EV charging capacity.
• Connect living spaces to a screened or covered porch and a well-drained patio through large sliders or folding doors.

Multi-gen flexibility

• Offer an optional main-level guest or in-law suite or a legal accessory dwelling unit where zoning and utilities allow.

Finishes and systems that command premiums

Focus upgrades on function, durability, and low-maintenance luxury that appeals broadly.

Interior specifications

• Kitchens drive emotion and value. Use custom or semi-custom cabinetry, integrated appliances, and a generous pantry system.
• Provide continuous hardwood on main living levels and tile in baths. Avoid carpet on the main floor.
• In the primary bath, use quality tile, frameless glass, dual vanities, and an efficient, high-flow shower. Add a freestanding tub if space allows.
• Built-ins in living areas and a fitted mudroom boost daily utility and perceived quality.

Energy and smart systems

• High-efficiency HVAC with heat pumps, whole-house ventilation, and tankless or high-efficiency water heaters can differentiate your home and support energy ratings.
• Use large, energy-efficient windows to maximize daylight and comfort. Where near major roads, consider sound attenuation.
• Prewire for data, security, smart devices, and EV charging.

Outdoor living and landscape

• Screened or covered porches with fans extend seasonal use and are prized in this climate.
• Execute a durable stone or paver patio with proper drainage, a gas stub for grills, and optional outdoor kitchen elements.
• A fire feature increases year-round appeal. Preserve mature trees where safe and add privacy buffering.
• Create a level, usable yard with low-maintenance native plantings and thoughtful lighting.
