Overview

House Extensions Built for New Jersey Homes

Extend the rooms you already use and gain the space your household needs — without moving.

A house extension expands existing living areas rather than adding an entirely separate wing. It is the right choice when your kitchen is too tight, your family room can't hold everyone, or you need a larger dining area that connects to the yard. All About Additions LLC builds extensions across Edison and nearby New Jersey communities with a focus on how the new space flows into the old.

The details matter most where old meets new. We plan floor transitions, ceiling heights, window alignment, and exterior siding so the extension does not look bolted on. Insulation, drainage, and structural connections are handled properly the first time, which is what protects your investment years down the road.

Every extension begins with a free consultation and a detailed written proposal. We talk through how much space you can realistically gain, what the setbacks and permitting look like for your lot, and what the finished project will cost. You approve the scope before work starts, and we manage the trades, inspections, and schedule from there.

Because we are licensed and insured with 15 years in business and 200+ clients served, you get a contractor who is accountable from the first day of demolition to the final coat of paint — and a home that fits your life without a move.

Answers

House Extensions FAQs

What is the difference between a house extension and a home addition?

An extension expands an existing room or area, while an addition typically creates new rooms or a new section of the home. Both increase usable square footage, and we build both.

Will a house extension match my existing home?

Yes. We match siding, rooflines, trim profiles, and interior finishes so the extension blends with the original structure.

How far can I extend my house in New Jersey?

Local zoning setbacks and lot coverage limits determine how far you can build. We review those requirements for your property during the free consultation.
