From the stone Victorians of Chestnut Hill and Mt. Airy to the twin homes of Roxborough and East Falls to the detached homes of the Far Northeast — we design and install custom sunrooms, screen rooms, and patio enclosures across Philadelphia’s neighborhoods, working with the city’s distinctive architecture and lot conditions.
Philadelphia is a city of neighborhoods, each with its own architecture and its own relationship to outdoor space. We design and install custom sunrooms, screen rooms, and patio enclosures across the city — with particular focus on the neighborhoods where homes have the yards, twins, and detached lots that suit these additions.
The Northwest is our strongest Philadelphia territory. Chestnut Hill, with its Wissahickon schist stone homes and tree-lined streets, has the architecture and lot sizes that make for beautiful sunroom projects. Mt. Airy, West Mt. Airy, Germantown, East Falls, and the Roxborough-Manayunk area offer a mix of stone twins, detached Victorians, and homes with real back yards — ideal candidates for rear sunrooms, screen rooms, and patio enclosures. These neighborhoods feel almost suburban while remaining firmly in the city.
The Far Northeast — neighborhoods like Fox Chase, Somerton, Bustleton, and Torresdale — has substantial post-war detached and twin homes on larger lots, another natural fit for outdoor living additions. Elsewhere, from West Philadelphia’s larger Victorian twins to pockets of South Philadelphia and the river wards, we assess each property individually.
Philadelphia borders three other counties we serve: Montgomery County to the north and northwest, Bucks County to the northeast, and Delaware County to the southwest — and Camden County, New Jersey sits directly across the Delaware River. Many of our Philadelphia clients have moved to or from these neighboring areas, and we work across all of them.
In a city where lot sizes vary block to block, product choice depends heavily on your specific home and yard. A Chestnut Hill stone home might take a full four season sunroom; a Mt. Airy twin might be perfect for a rear patio enclosure; a Roxborough home might want a screen room off the back. We build all four products across Philadelphia and help you find the one that fits your property.
Fully insulated, year-round rooms — best suited to Philadelphia’s detached and twin homes in the Northwest and Northeast where the lot accommodates a permanent addition.
Light-filled spring-through-fall rooms — a more accessible addition that works well on city homes with a back yard to build into.
Built around an existing rear patio or deck — often the ideal Philadelphia solution, turning a compact city back yard into usable enclosed space without a ground-up addition. Glass, screen, or combination styles.
Insect and weather protection for a rear porch or patio — a popular, space-efficient choice for city homes where an open-air room with coverage is exactly what the back yard needs.
Building outdoor living additions in Philadelphia is different from building in the suburbs, and being straight about those differences is part of how we earn trust. City lots, a distinctive permit process, active historic districts, and the realities of rowhouse and twin architecture all shape what’s possible. Here’s what to know.
Philadelphia’s classic narrow rowhomes — often just 14 to 18 feet wide with little or no rear yard — frequently don’t have the lot geometry for a traditional sunroom, and we’ll tell you honestly if yours doesn’t. But much of the city tells a different story: the stone twins and detached homes of Chestnut Hill, Mt. Airy, and East Falls; the larger lots of the Far Northeast; the deep back yards found throughout the Northwest. Where there’s a rear yard or an existing deck or patio, there’s usually a path to an outdoor living addition — whether a full sunroom, a patio enclosure, or a screen room. The first thing we do at consultation is assess whether and what your specific lot can support.
Philadelphia has numerous locally designated historic districts — Chestnut Hill, parts of Germantown, Society Hill, Old City, and others — where exterior modifications require review by the Philadelphia Historical Commission. If your home is historically designated, an addition typically needs Commission approval, and in-kind or period-appropriate materials may be required. This is most relevant in exactly the Northwest neighborhoods where sunrooms are most popular. Our project managers handle Historical Commission submissions as part of the permit process — it adds time, but it’s a well-trodden path and not a barrier to a well-designed project.
Philadelphia’s Department of Licenses and Inspections (L&I) runs the city’s permitting, and the city process differs from the suburban township model. Zoning in Philadelphia can be involved — some projects require zoning review or variances depending on lot coverage, rear-yard requirements, and the specific zoning district. We handle the L&I permit and zoning process on your behalf and set realistic timeline expectations based on your project and neighborhood. The city process generally takes longer than a suburban township, and we build that into the schedule honestly from the start.
Philadelphia’s residential architecture is some of the most distinctive in the country — brick rowhomes, stone Wissahickon schist twins, streetcar-era Victorians with porches and bay windows. A sunroom or enclosure on these homes has to respect that character. On a stone Northwest twin, that usually means a gable roof and trim coordinated with the home’s existing detailing. On a brick home, it means matching proportions and color sensibilities. Our designers work with the city’s architectural language rather than imposing a suburban template on an urban home.
From a Chestnut Hill stone home to a Far Northeast twin, the same factory-trained installers do the work — our own team, never subcontractors. City projects with tight access and historic detail demand experienced hands, not rotating crews.
Half a century of structural coverage on every project, in every Philadelphia neighborhood. No depreciation, no fine print.
Our products are manufactured in Pennsylvania, engineered for the exact climate Philadelphia experiences — hot humid summers, freeze-thaw winters, and everything between.
Philadelphia’s L&I permitting and Historical Commission review are their own world. Your dedicated project manager handles the city process — zoning, permits, historic review where applicable — so you don’t have to navigate L&I yourself.
We install across Philadelphia’s neighborhoods, with particular strength in the areas where homes have the yards and lots that suit outdoor living additions:
Chestnut Hill | Mt. Airy | West Mt. Airy | Germantown | East Falls | Roxborough | Manayunk | Wissahickon | Andorra
Fox Chase | Somerton | Bustleton | Torresdale | Holmesburg | Mayfair | Rhawnhurst | Burholme
West Philadelphia | Overbrook | Wynnefield | Cedarbrook | parts of South Philadelphia | and neighborhoods throughout the city — assessed property by property
Not sure if your block and lot can support a sunroom or enclosure? That’s exactly what we determine at the free consultation. Submit your address and we’ll give you an honest answer.
We also serve the surrounding region — explore neighboring Montgomery County or our complete service area.
It depends entirely on your lot. Many classic narrow rowhomes — 14 to 18 feet wide with little rear yard — don’t have room for a traditional sunroom, and we’ll tell you honestly if yours doesn’t. But if you have a rear yard, an existing deck, or a back patio, there’s often a path to a patio enclosure or screen room even on a rowhome. And the city’s many twin and detached homes, especially in the Northwest and Northeast, are excellent sunroom candidates. The free consultation is where we assess exactly what your specific property can support.
If your home is designated historic, exterior additions require review by the Philadelphia Historical Commission, and period-appropriate materials and proportions may be required. This is common in the Northwest neighborhoods where sunrooms are most popular. It adds time to the permit process, but it’s a well-established path — our project managers prepare and submit the Historical Commission application as part of the project and design with review expectations in mind from the start.
The city process through the Department of Licenses and Inspections (L&I) is different from suburban townships and generally takes longer, particularly when zoning review or a variance is involved. We handle the entire L&I permit and zoning process for you — and we set honest timeline expectations up front rather than promising suburban-speed approvals the city can’t deliver. Knowing how the city process actually works is part of what we bring to a Philadelphia project.
Our strongest Philadelphia territory is the Northwest — Chestnut Hill, Mt. Airy, Germantown, East Falls, Roxborough, and Manayunk — where stone twins and detached homes with real yards make ideal candidates. We also do significant work in the Far Northeast (Fox Chase, Somerton, Bustleton, Torresdale) where post-war detached and twin homes sit on larger lots. That said, we assess homes throughout the city individually — if you have the yard for it, we’ll travel to you.
We design the addition to coordinate with your home’s existing character rather than to literally replicate masonry. On a Wissahickon schist stone twin, that means a gable roofline, trim, and proportions that complement the stone. On a brick rowhome or twin, it means matching color and proportion sensibilities. The goal is an addition that looks like it belongs to the home — our designers work with the city’s distinctive architecture, not against it.
