Home Additions & Extensions - Design & Build

On Long Island, Home extensions & home additions are a great way to gain valuable space without the hassle of moving. Extensions generally mean adding another room with a foundation to the outside of an existing home. Home additions and dormers generally mean extending upward, adding or expanding an upper level to your home.

Going Up - Home Additions & Home Dormers

If you have limited space on your property, then going up with a home addition is probably a wise move. Adding a second floor or constructing a dormer keeps your yard space intact and utilizes the free real estate above your home.

Spreading Out - Home Extensions

Plenty of land? Choosing to add a home extension usually means that there will be less disruption to your existing home. Home extensions typically can be built “outside” your existing home and connected to the existing part of your home just before completion. Your mileage may vary! Trade some yard space for a beautiful Long Island home extension.
