Milton's Construction builds home additions in Farmingdale — dormers and second stories on village Colonials and ranches, room extensions, and in-law suites.
Farmingdale homeowners add space for the same reason most Long Island families do: the house worked fine for a couple and it no longer works for a family, an aging parent, or a teenager who needs a bedroom that is not in the basement. What makes Farmingdale interesting is the variety of housing that drives those projects. In the village, you're typically looking at Colonials and Capes where the attic space is partially finished or entirely wasted — ideal candidates for a full dormer that adds a bedroom and a bath without touching the footprint. Out in the surrounding neighborhoods, the mid-century ranches and high-ranches are single-story homes on lots that usually have room for a rear addition or, in the right cases, a full second story.
We've been building additions on Long Island for over forty years. We handle the design, the structural engineering coordination, the permit filing — through the Village of Farmingdale Building Department for village addresses and the Town of Oyster Bay for South Farmingdale — and every trade from foundation to final finish. One team, one contract, one point of contact. Call or text 631-741-0199 for a free written estimate.
A Cape Cod near Farmingdale Main Street typically has a second floor that is half the square footage of the first — two bedrooms tucked under a roofline that cuts the ceiling height on every side. A full shed dormer opens that floor to full ceiling height across the width of the house, which can convert a cramped half-story into two proper bedrooms and a full bath. It is one of the best returns per dollar of any project on a Cape, and Farmingdale has plenty of them. The permit goes to the Village of Farmingdale Building Department for properties inside the village limits.
For the ranches and high-ranches in South Farmingdale, Bethpage, and Massapequa, the addition options depend on the lot and the foundation. A rear extension adds square footage on the ground floor and is typically the most straightforward path. A full second-story addition — lifting the roof and framing a complete second floor — is a larger undertaking but can double the living space of a ranch. Both routes require permits through the Town of Oyster Bay for South Farmingdale addresses, and we manage that process.
In-law suites have become one of the most requested projects we see on Long Island, and Farmingdale is no exception. A ground-floor addition with a bedroom, full bath, and kitchenette gives an aging parent independence while keeping them close. For ranches with an attached garage, converting the garage and adding a small addition behind it is a common path. Zoning rules in the Village of Farmingdale and the Town of Oyster Bay govern what is allowed for accessory dwelling units — setbacks, square footage limits, separate-entry requirements — and those rules have been evolving.
We know what is currently permitted, we help you design within those limits, and we handle every permit and inspection. A free written estimate outlines the full scope and cost before you commit to anything. Call or text 631-741-0199.
Yes. A dormer is a structural alteration that affects the roof, the framing, and often the electrical and plumbing for a new bath. It requires a building permit from the Village of Farmingdale Building Department for properties inside the village. For South Farmingdale addresses, the permit goes through the Town of Oyster Bay. We handle the application and all required inspections.
It depends on the foundation. Many mid-century ranch foundations in the Farmingdale area were poured with enough capacity to support a second story, but we verify that before designing anything. If reinforcement is needed, we build it into the scope. We give you a clear answer in the written estimate so you know exactly what the project involves.
A modest rear addition or finished dormer on a Farmingdale Cape or ranch typically starts in the mid-to-high five figures and moves into six figures as the scope grows. A full second-story addition is a more significant investment. The only accurate number is in a written estimate based on your home and your goals. Ours is free — call or text 631-741-0199.
