Home Additions & Add-a-Levels at the Jersey Shore

Expand your home without giving up the location you already love. KBR Builders specializes in large-scale home additions, second-story additions, and add-a-level projects throughout the Jersey Shore.

From structural planning and foundations to framing, roofing, mechanical systems, interior finishes, and final inspections, our team manages the entire construction process and integrates the new space with the existing home.

Types of Home Additions We Build

Kitchen & Family Room Expansions

Open and expand the main living areas of the home with additional square footage, larger kitchens, improved layouts, and stronger connections between indoor and outdoor spaces.

Multi-Room Additions

Combine several new spaces into one coordinated addition, such as bedrooms, bathrooms, family rooms, laundry areas, offices, and expanded living spaces.

Rear & Side Home Additions

Expand the footprint of the existing home to create larger kitchens, family rooms, dining areas, primary suites, mudrooms, and additional living space.

Second-Story Additions

Add significant square footage above an existing home with new bedrooms, bathrooms, primary suites, or complete second-floor layouts.

Add-a-Level Projects

Transform a one-story or undersized home by adding an entirely new level. These projects can involve major structural reinforcement, new stairs, roof removal, framing, mechanical upgrades, and extensive renovation of the existing home.

Primary Suite Additions

Create a larger primary bedroom, bathroom, walk-in closet, and private living area while integrating the new space with the existing floor plan.

Home Additions Require More Than Extra Square Footage

Adding onto an existing home requires careful coordination between new construction and the structure that is already there.

Foundations must support the new space. Framing needs to tie into the existing house correctly. Rooflines, windows, siding, plumbing, electrical, HVAC, insulation, and interior finishes all need to work together.

KBR Builders manages these details throughout the project and works with architects and structural engineers when required to make sure the addition is built correctly from the structure outward.

Build Up or Build Out?

Every property is different.

Building outward can be a great option when the lot has enough room and the goal is to expand kitchens, family rooms, primary suites, or other first-floor living spaces.

Building upward may make more sense on tighter Jersey Shore lots where homeowners want substantially more square footage without increasing the footprint of the home.

KBR Builders helps homeowners evaluate the construction considerations involved with each approach, including the existing structure, proposed floor plan, zoning, setbacks, foundation requirements, structural engineering, and overall project scope.
