Home Additions Near White Plains, NY

Add the Space Your Home Is Missing

Design + build additions handled by one accountable team, so the new space works for your family and feels like it was always part of your home.

Designed & Built To Feel Like It Belongs

Your addition is designed around the home you already have, so the rooflines, materials, finishes, and details come together naturally.

Know What Works Before You Commit

We look at your property, zoning, setbacks, and budget early so you can make smart decisions before investing in a full design.

Have One Team That's Always Accountable

Design, permits, site work, construction, and finishes stay coordinated, with one team responsible to keep it all moving through every phase.

Need More Space in Your Westchester Home?

Most people who call us about an addition already love where they live. The neighborhood works, the schools work, the commute works, and the house is the only thing that stopped keeping up. Adding on solves that without putting your family through a move, a bidding war, and a new mortgage.

Our in-house architects*, designers, carpenters, and builders handle every part of it, so your addition lines up with the house you already have, right down to the trim.

Types of Home Additions

What Kind of Addition Are You Thinking About?

There are three ways to gain square footage. You can build up, build out, or finish space you already own like an attic, garage, or basement. These are the projects we take on most often.

Second Story Additions

Add a full floor and keep every inch of your yard. This is the biggest change you can make to a house without moving.

In-Law Suite Additions

A private space with its own bedroom, bathroom, and entrance, built for a parent, an adult child, or rental income.

Primary Suite Additions

A bedroom that finally fits the furniture, a closet worth walking into, and the bathroom you have been sketching in your head for years.

Garage Additions

Attached or detached, with room for the cars, the gear, and finished space above if you want it.

Bump-Out Additions

A few feet in the right direction can change how a kitchen, bathroom, or entryway works without touching the rest of the house.

Sunrooms and Screened Porches

Three-season space that connects the house to the backyard and gets used far more than people expect.

How It Works

What You Can Expect

1

Start With a Conversation

Tell us what is not working, what you want to add, and what you want to spend. We’ll walk the property with you and talk through what makes the most sense.

2

Plan the Addition Together

If we’re a good fit, we move into design, planning, and budgeting. We work through the layout, scope, permits, selections, and costs before construction begins.

3

Watch It Come To Life

Once the plan is set, we take it from there and keep the project moving, so you can focus on the enjoyable parts instead of managing the build.

New Square Footage Starts Below Ground

If you’re building out to add more space, we keep the site work connected to the rest of the project so everything starts on the right footing. Through De La Paz Masonry, our sister company, we handle the excavation, footings, foundations, concrete slabs, and drainage your addition needs.

Because the crews below ground and above ground are working as part of the same project, there are fewer handoffs, fewer delays, and one team responsible for keeping the work moving.
