Dormers & Extensions in Old Bethpage
Old Bethpage sits just north of Bethpage proper but on noticeably larger lots, with a mix of ranches and Cape Cods rather than the dense Cape grid to its south. Those bigger lots change the math. Where a compact Bethpage Cape points toward a dormer, an Old Bethpage ranch on a wider parcel often has room to grow outward, which makes ground-floor extensions a practical and popular choice here.
We build the full range in Old Bethpage: shed and gable dormers on the Capes, full second-story additions on the ranches, and rear and side extensions that take advantage of the extra yard. Families in the Plainview-Old Bethpage Central School District tend to invest in staying, so we see larger additions here, including kitchen and family room extensions and in-law suites that the roomier lots can accommodate.
The extra land is what sets Old Bethpage apart from Bethpage proper. Where a tight lot forces the decision upward into a dormer or a second story, an Old Bethpage parcel often has the side and rear yard to support a full ground-floor extension, an attached in-law suite, or a wide primary suite addition. Old Bethpage sits close to the Long Island Expressway and the Bethpage State Parkway, so our crews reach the neighborhood easily for consultations and daily supervision. We look at your specific lot, your setbacks, and how you want to use the space, then recommend whether building out, building up, or dormering the existing roof gives your family the most for the budget.

Old Bethpage Building Permits & Regulations
Old Bethpage falls under the Town of Oyster Bay for permits and zoning. Every dormer and extension requires stamped architectural and structural plans, a building permit, and inspections through the Town of Oyster Bay, plus zoning review for setbacks, lot coverage, and floor area ratio. The larger Old Bethpage lots often leave more room within setback and lot coverage limits, which opens up ground-floor extensions that a smaller parcel could not support, and we design to those numbers. Meigel handles all permitting from filing and plan corrections through the final inspection and certificate of occupancy.
