Floral Park sits at the western edge of Nassau County, directly on the Queens border along the Elmont/Bellerose corridor. It includes the incorporated Village of Floral Park as well as the Nassau County hamlet of North Floral Park. The housing stock here is primarily post-World War II Cape Cods and Colonial-style homes built between the late 1940s and the early 1960s — compact, well-maintained, and often on tight lots that make every square foot of enclosed living space genuinely valuable.
We build sunrooms and enclosed porches in Floral Park regularly. It is one of those Nassau communities where the lot doesn't give you a lot of outdoor room to spread out, but a three-season or four-season room off the rear of the house creates real additional living space without a full addition.
Cape Cod homes. The Cape Cod stock in Floral Park typically has a rear door that leads directly to a concrete patio or an existing open porch. These are natural sunroom locations — the structural tie-in to the house is straightforward, the footprint is usually 12x16 to 14x20, and the project can often be completed in 3–4 weeks from permit approval.
Colonial homes. Floral Park's Colonials are often slightly larger than the Capes, with more defined rear yards. A patio enclosure or four-season room off a Colonial's rear door or slider is a common project here, particularly for families that want a connected informal dining or family room.
Lot constraints. Floral Park lots are typically 5,000–7,500 sq ft. Rear and side setbacks under Town of Hempstead rules govern exactly how close to the property line you can build. We check these before proposing a footprint — there's no point designing a room you can't permit.
This is the most common question we get from Floral Park homeowners, so it's worth a direct answer.
Three-season rooms are the more affordable option. They use single-pane tempered glass or glass-over-screens panels in aluminum frames — not thermally broken, not insulated. They are comfortable from April through October in Nassau County and occasionally on mild winter days if you have supplemental space heating (a plug-in radiator or electric baseboard). They are not designed for mid-January use without that supplemental heat, and without insulation you will feel the cold through the glass panels during deep winter.
Cost for a three-season room in Floral Park: typically $20,000–$36,000 for 130–175 sq ft depending on the specific configuration.
Four-season rooms are fully insulated: double-pane low-E glass, thermally broken aluminum frames, insulated roof panels. They function as a genuine additional room year-round. They tie into your HVAC system or, if that's not practical, get a ductless mini-split. The room is comfortable in January and in July.
Cost for a four-season room in Floral Park: typically $40,000–$62,000 for the same footprint.
Which one is right for your home? If you plan to use the room from May through October only, a three-season room is a good value. If you want year-round use — breakfast room, home office, TV room that you use in all weather — the four-season option pays for itself in usability. We'll give you a straight answer after seeing the space.
The incorporated Village of Floral Park issues its own building permits for projects within the village boundaries. For homes in the hamlet of North Floral Park or in adjacent unincorporated Nassau areas that fall under Hempstead town jurisdiction, the Town of Hempstead Building Department handles the permit.
Key points about the Floral Park permit process:
We handle the entire permit process. You won't need to visit the building department or track down your survey — we collect what we need and manage the application from submission to final inspection.
What is the most popular sunroom type in Floral Park?
Three-season rooms and patio enclosures are the most common projects in Floral Park. The existing rear porch or patio footprint makes the construction straightforward, and the cost is manageable for Cape Cod and Colonial homes on typical Floral Park lots.
Can I build a sunroom on a small Floral Park lot?
Usually yes. Setbacks limit how close to the property line you can build, but most Floral Park homes have enough rear yard to accommodate a 12x16 or 14x16 room without variance. We check your specific lot before quoting.
How long does a Town of Hempstead sunroom permit take?
Typically 4–8 weeks for an uncontested application with complete documentation. We submit complete packages to minimize review cycles.
Does a sunroom addition require a survey update in Floral Park?
Yes. Any room addition that increases the built footprint of your home will need to be reflected on an updated survey or plot plan. We coordinate with surveyors as part of the permit package when needed.
Can I use an existing concrete patio slab as the foundation for a sunroom?
Possibly. If the existing slab is in good condition, properly reinforced, and meets the depth and thickness requirements for the proposed room load, it can often serve as the foundation. We evaluate the existing slab as part of the site assessment before recommending a foundation approach.

Recent Work
We haven't posted a Floral Park-specific check-in yet, but here is recent work from the Nassau County towns nearest to you.
Built a 14×18 four-season sunroom off the back of a Garden City colonial — insulated Low-E windows, thermally broken aluminum frame, HVAC tie-in, and a coffered ceiling to match the interior.
Enclosed an existing 12×20 concrete patio with sliding window panels and a studio roof — no foundation work needed. Added a ceiling fan and recessed lighting.
Replaced a failing 2008-era sunroom with a properly engineered 16×18 four-season room — triple-pane windows, R-30 roof insulation, and split-system mini-split for year-round use.
Enclosed a 10×18 deck with a three-season patio enclosure — vinyl panels, aluminum frame, and a cathedral ceiling that tied into the gable end of the house.
Added a 14×20 year-round sunroom off the kitchen with radiant floor heat, insulated windows, and a heated slab foundation. Functions as a second dining area in winter.
12×16 three-season sunroom on a new concrete pier foundation. Double-pane windows on all three walls with a cathedral ceiling and exterior covered porch overhang.
Homeowner Reviews
Nearby Nassau County homeowners — we build across the same building departments, codes, and soil conditions.
“Tom and his crew built our four-season sunroom in under three weeks. We use it every single day, even in January. Best investment we made in this house.”
Jennifer M.
Massapequa, Nassau County
“We had a three-season room built last spring. By October we were still using it comfortably. The window quality and insulation are impressive for the price point.”
David W.
Garden City, Nassau County
“Tom gave us an honest assessment — told us our deck wasn't suitable for a full four-season room and recommended a three-season instead. Saved us $20k and we love the result.”
Susan T.
Great Neck, Nassau County
“Had a leaking sunroom installed by another company five years ago. Tom's team ripped it down, fixed the foundation issues, and built a proper four-season room. Night and day difference.”
Karen B.
Manhasset, Nassau County
“Replaced an old screened porch with a proper three-season sunroom. The difference in build quality is obvious. Solid framing, clean welds, no rattling when the wind picks up.”
Thomas H.
Merrick, Nassau County
“We live on a corner lot in Levittown and thought we didn't have room for a sunroom. Tom found a way to make it work with a 12x14 footprint off the kitchen. Perfect fit.”
Maria G.
Levittown, Nassau County
