Overview

Home Additions on the Jersey shore.

An addition is the highest-trust project a homeowner can hand a contractor. Foundation work, framing, roof tie-ins, electrical, HVAC, and interior finishes all have to land cleanly so the new space doesn't look like it was bolted on. We design and build additions across Ocean and Monmouth County — rear extensions, second-story pop-ups, sunrooms, primary-suite additions, and garage conversions — coordinated under one project lead with permits and engineering handled in-house.

What sets this work apart

The four pillars.

01

Real architectural integration

Roofline matching, siding-and-trim continuation, and interior-finish matching so the addition reads as part of the original home — not a 1990s afterthought.

02

Foundation & framing

Frost-depth footings, foundation walls, structural framing, and roof tie-ins built to code with engineering coordinated when required.

03

Permit & engineering

Architectural drawings, structural engineering, zoning variances, and every township permit pulled and managed by us.

04

Seamless finishes

Hardwood, trim, and paint matched into the existing home so transitions disappear. Where matches aren't possible, we design a deliberate transition (beam, header, threshold) so it looks intentional.

Our Process

From first call to final walk — no mystery weeks.

01

Consultation & feasibility

On-site walk to discuss what you want, lot constraints, setbacks, and rough budget range.

02

Design & engineering

Architectural drawings and structural engineering — coordinated with our architect partners or yours.

03

Permits & zoning

We file the building permit and handle zoning variances if the addition triggers them.

04

Foundation & framing

Footings, foundation, framing, roof tie-in, and weather-tight envelope.

05

MEP, finishes & punch

Mechanical/electrical/plumbing rough-in, insulation, drywall, finishes, and final inspection.

Addition types we build

What's actually included.

Most additions fall into one of these categories.

Standard scope:

  • Rear & side additions
  • Second-story additions
  • Sunrooms & four-season rooms
  • Garage conversions
  • Foundation & framing
  • Roof tie-ins

Rear & side additions

Family-room extensions, primary-suite additions off the back of the home, and kitchen bump-outs.

Second-story additions

Full or partial second-floor pop-ups — usually the highest ROI per square foot when lot setbacks are tight.

Sunrooms & four-season rooms

Glass-heavy sunrooms with full HVAC integration, built to be used 12 months a year.

Primary-suite additions

Bedroom + walk-in closet + primary bath additions, often combined with a roof modification on the original house.

Garage conversions

Existing garages converted into livable space (rec room, in-law suite, office) with full insulation and HVAC.

Above-garage additions

ADUs, home offices, and bonus rooms built above existing or new garages — often without expanding the home's footprint.

Project Showcase

Exterior Siding & Skirting Rebuild

NJ

Tired, weather-worn exterior fully rebuilt — old siding and skirting torn off, framing and rough openings addressed where needed, then wrapped with fresh tan vinyl siding, crisp white skirting, new trim, and a new window for a clean, weather-tight finish.

FAQ

Common questions about home additions.

How much does an addition cost?+

Most additions at the shore run $250–$450 per finished square foot depending on complexity, finishes, and whether it includes a kitchen or bath. We give detailed quotes after architectural drawings are in hand.

How long does an addition take?+

From signed permits, most additions run 4–8 months. Design and permitting typically add 2–4 months before construction starts.

Do I need an architect?+

Yes for almost any structural addition. We work with trusted local architects or your own — and coordinate the drawings to keep cost and time tight.

Can we live in the house during construction?+

Usually yes — additions are typically built on the outside of the home and tied in late in the schedule, so daily life inside stays mostly normal until the cut-in happens.

Do you handle zoning variances?+

Yes. If your addition triggers a setback variance or other zoning issue, we manage the application and represent the project at the zoning board.
