From dormered Capes to two-story rear extensions and permitted in-law suites, Milton's Construction builds additions that grow with Brentwood families.
Brentwood has one of the highest concentrations of multigenerational households in all of Suffolk County, and the housing stock — Capes, ranches, and splanches on modest lots — was not designed with that in mind. A single-story Cape originally built for a couple and two kids is now asked to house an aging parent, a young family, and sometimes a returning adult child. The answer isn't always moving. Often it's building up, building back, or finishing out space that's already there.
Milton's Construction specializes in exactly these additions. We design second-story additions that work with existing foundation loads, rear extensions that maximize what Town of Islip zoning allows, and full accessory apartments and in-law suites that meet the code requirements for legal occupancy. We file every permit, manage every inspection, and keep the project on one team from design through certificate of occupancy.
Town of Islip has specific regulations for accessory apartments, including owner-occupancy requirements and size limitations. Navigating those rules correctly at the permit stage is essential — an improperly permitted addition can create problems when you sell or refinance. Our team is familiar with the Town of Islip Building Division's requirements for accessory dwellings in Brentwood, and we design additions that pass review the first time.
A second-story addition over an existing ranch or expanded Cape is one of the highest-return projects available to Brentwood homeowners. It doubles living space without touching your yard, and it can be designed with a private entrance and separate climate zone for an in-law suite or rental unit. We assess the existing foundation and framing during our estimate to determine what structural reinforcement, if any, the first-floor walls and sill plate require before adding weight above.
Home additions in Brentwood range considerably in cost depending on scope. A simple first-floor rear extension without plumbing differs from a full second-story addition with a kitchen and bathroom. Dormer additions to open up a Cape attic fall somewhere in between. None of those figures mean much without seeing your specific home and understanding exactly what you want to accomplish — which is why we offer free written estimates.
The design-build model means you're not paying separate design fees to an architect before any construction pricing is on the table. We assess, design, and price as a single engagement. Call or text 631-741-0199 to get started.
Yes, but the requirements for accessory apartments in the Town of Islip are specific — owner occupancy is typically required, and there are size and entry requirements that must be met to qualify for a permit. We walk you through those rules during the estimate and design the space to satisfy them so the permit goes through cleanly and you have a legally occupiable unit.
We start by evaluating the existing foundation, sill plate, and first-floor wall framing to determine load capacity. In many Brentwood ranches, some reinforcement is needed before adding a full second story. We include that structural work in the permit drawings and scope, so there are no surprises mid-project. From there it's standard framing, roofing, windows, mechanical rough-ins, and interior finish.
Most Cape Cods in Brentwood have steep rooflines that make the upper level barely usable — cramped knee walls and low ceilings that can't support real bedrooms. A shed or gable dormer opens that space up to full standing height on one or both sides, turning what's often used as storage into actual living space. We handle the framing, roofing, windows, and insulation as a single permitted project through Town of Islip.
