From the Victorian streets of Lambertville and the river towns to the farmhouses and colonials of the Flemington heart to the Highlands country around Round Valley — we design and install custom sunrooms, screen rooms, and patio enclosures across all of Hunterdon County.
Hunterdon County is New Jersey at its most pastoral — roughly 130,000 residents across rolling farm country, Delaware River towns, and Highlands ridges, about an hour up the Route 202 corridor from our West Conshohocken headquarters. It’s a county of preserved farmland and horse fences, of village greens and river Victorians, where twenty-six municipalities — including two Clintons and two Lebanons — each run their own permits, and where most lots come with a well, a septic system, and a view worth building a glass room around. We serve every corner of it.
Named in 1714 for colonial governor Robert Hunter, Hunterdon grew as mill-and-farm country along the Delaware and its creeks — and the river towns still carry the old bones beautifully. Lambertville, paired with New Hope across the bridge, has become the antiques-and-arts capital of the state; Frenchtown, Milford, and Stockton keep their landing-town charm along the water and the Delaware & Raritan Canal towpath; and in the Delaware Township countryside, Green Sergeant’s Covered Bridge — built in 1872 — remains the last of New Jersey’s historic covered bridges still carrying traffic through Sergeantsville.
Flemington holds the county’s center — seat since the 1780s, its historic courthouse made a household name by the 1935 Lindbergh trial, its later decades famous for Stangl pottery, cut glass, and the outlet era. Around it, Raritan Township carries most of the “Flemington” addresses across its colonials and newer neighborhoods, Readington spreads east through Whitehouse Station and the Solberg Airport fields where the summer balloon festival lifts off, and the Amwells roll south through Ringoes toward the river hills.
The north is Highlands country — Clinton’s twin municipalities around the old mill town, High Bridge and Califon on the South Branch, Tewksbury’s horse farms and the postcard village of Oldwick, and the reservoir country of Round Valley, New Jersey’s deepest lake, and Spruce Run. It’s the most preserved, most protected corner of a county that leads the state in preserved farmland — which brings its own set of rules, covered honestly below. Add the commuter spines of 78, 202, and 31, and Hunterdon manages a rare trick: genuinely rural life within reach of everything.
Hunterdon County is about an hour from our West Conshohocken headquarters, straight up the Route 202 corridor and across the river at Lambertville. Looking beyond Hunterdon, we also serve Bucks County just across the Delaware.
Whether you’re adding a four season sunroom to a farmhouse outside Sergeantsville, enclosing the patio behind a Raritan Township colonial, or designing an era-true room for a Lambertville Victorian, the right product depends on your home and how you’ll use the space. We build all four primary outdoor living products across Hunterdon County.
Fully insulated, year-round rooms — and in a county this scenic, the argument makes itself: preserved farmland out the glass in January, the ridge line in October, insulated comfort through all four seasons. Real living space with Hunterdon’s best feature built in.
Light-filled rooms designed for spring through fall enjoyment — a natural fit for a county whose calendar runs from the first river-town weekend to the last leaf on the ridge, stretching the outdoor season at both ends.
Built around your existing patio, deck, or porch — and a strong fit across the county’s housing range. The colonials of Raritan, Readington, and Clinton Townships almost universally carry a rear patio or deck waiting to become a real room; farmhouse porches convert beautifully with era-true detailing; and the enclosure is the most integrated, most economical addition either can take. Glass, screen, or combination styles.
Insect protection plus overhead weather coverage for the months Hunterdon lives outside — evenings on the farm, dinners above the river — without the mosquitoes that come with creeks, ponds, and a county full of old trees.
Hunterdon projects come with considerations rooted in what makes the county itself — twenty-six municipalities with paired names built to confuse, a Highlands protection region across the north, river-town floodplain and canal zones along the Delaware, and rural lots where the well and septic map comes first. Here’s what shapes projects here.
Hunterdon’s municipal map is a local sport. Clinton Town and Clinton Township are separate municipalities with separate permit offices; so are Lebanon Borough and Lebanon Township; and most “Flemington” addresses sit in Raritan Township rather than the borough — the same envelope-versus-parcel game played across twenty-six jurisdictions, each with its own zoning, setbacks, and process. It matters at exactly one moment, and it’s our job to sort: our project managers confirm your actual municipality from your parcel during the consultation and design to the correct rulebook from the start, so the county’s naming quirks stay trivia night material rather than a project complication.
Hunterdon’s landscape is protected on purpose, and two frameworks do the protecting. Across the county’s north and west runs the Highlands Region — and here’s the honest good news: additions and improvements to existing single-family homes are generally exempt from the Highlands permitting layer, so for most homeowners the Act protects the view without complicating the project; we confirm your parcel’s status and any municipal overlay as part of the consultation. Along the Delaware, the river towns carry their own layers — the D&R Canal review zone near the towpath, and the river’s mapped floodplain, which has earned respect within living memory. For parcels near the water, we confirm flood zone status by address before the footprint is final, and where a zone applies, the room is designed to its standards from the start. Either way, you’ll know exactly where your parcel stands before anything is drawn.
The county’s housing asks for three kinds of craft. Its farmhouses and village homes — Sergeantsville to Oldwick — deserve era-true additions: attachment detailed for old framing and stone, rooflines that defer to the original, divided-light glass and trim at the home’s level of finish. Lambertville’s Victorians bring compact river-town lots where proportion does double duty and an addition should read as a considered chapter in the house’s story. And the wooded acre — Hunterdon’s signature lot — starts with siting: well and septic setbacks shape where a room can sit, tree canopy factors into orientation and footings, and the view usually settles the rest. It’s work a consultation visit resolves — and a glass room facing preserved farmland is about the best reward this business offers.
Whether your home is a farmhouse in Delaware Township, a Victorian in Lambertville, or a colonial in Raritan or Readington, the same factory-trained installers do the work — our own team, never subcontractors.
Half a century of structural coverage on every project. No depreciation, no fine print — a commitment at home in a county still crossing its 1872 covered bridge.
Our products are manufactured in Pennsylvania — just across the river — and engineered for the Delaware Valley’s humid summers and freeze-thaw winters. Regionally made rooms for a county that values things built to last.
Twenty-six permit offices with paired names, the Highlands across the north, floodplain and canal zones on the river, wells and septic nearly everywhere — a Hunterdon project manager has to know which applies to your specific parcel. Yours confirms it during the consultation and handles the right path from there.
We install across the river towns, the Flemington heart, and the Highlands north. A representative sample of the communities we serve, organized by region:
Lambertville | Frenchtown | Milford | Stockton | the Delaware Township countryside and Sergeantsville
Flemington | Raritan Township | Readington and Whitehouse Station | Ringoes and the Amwells | Kingwood and Franklin
Clinton Town and Clinton Township | Annandale | High Bridge and Califon | Glen Gardner, Hampton, and Bloomsbury | Lebanon Borough and Lebanon Township | Tewksbury and Oldwick | the Round Valley and Spruce Run country

Yes — Hunterdon is about an hour up the 202 corridor, crossing at Lambertville, and we plan consultations and installations there as dedicated visits. It changes nothing about what we build, the crews doing the work, the warranty, or the design attention your project gets. The river is a border on the map, not in our operations.
Welcome to Hunterdon geography — the county runs twenty-six municipalities, including two Clintons, two Lebanons, and a Flemington address that usually means Raritan Township. Each issues its own permits under its own zoning, and your envelope won’t tell you which. Your parcel tells us everything: we confirm your actual municipality during the consultation and prepare the correct submission, so the answer becomes our job rather than your homework.
In almost all cases, yes — and the honest news is better than the rumor. Additions and improvements to existing single-family homes are generally exempt from the Highlands Act’s permitting layer, so for most homeowners the Act protects the landscape without complicating the project. We confirm your parcel’s Highlands status and any municipal overlay during the consultation, and prepare whatever the correct path requires — which, for a typical home addition, is simply your township’s standard permit.
Yes — with design that takes the assignment seriously. Attachment details are worked out for old framing and stone construction, rooflines follow the original pitch and defer to the home’s massing, glass is divided in proportions the period would recognize, and trim and materials are chosen at the house’s level of finish. The standard is an addition the original builders would have approved of — a considered chapter, not an interruption.
It shapes the design in good ways. Well and septic setbacks determine part of the buildable envelope, tree canopy factors into orientation and footings, and the view usually decides the rest — a site visit settles all of it in an afternoon. Rural siting is standard work for us, and the reward on a Hunterdon acre is a room aimed at scenery most counties can’t offer.
