Beautiful Home Additions on the East-End of Long Island in the Hamptons

Seamless home additions create a fuller, richer life for you and your family


You love your home, neighborhood, and neighbors, but your family or weekend guest list is growing and you’re running out of space. Or maybe your cramped and outdated kitchen doesn’t give you the room you need for entertaining. Does this describe your situation? We constantly hear from Long Island homeowners who want to stay put, but don’t see how to make it work.

FD Building Co. can help you explore your options for expanding your living space with a beautiful new addition. Want to add a second story master suite with deck? Could your small bungalow use a larger open plan kitchen? From minor alterations to whole house renovations, we can design and build the additional space you need.

Kitchen Additions and Extensions

Whether your home is located in Southampton, East Hampton, or one of Long Island’s other charming towns, our design team takes your vision and creates an addition that meets your wants, needs, and budget.

We have a wealth of experience in custom home building and residential remodeling throughout Suffolk County. And over the years we’ve fashioned a design build process that gives you the greatest value while reflecting your vision and meeting your family’s needs.

Projects we design and build include:

  • Master Suite Additions. Always dreamed of a retreat like master suite? We can design a ground level or second story bedroom with spa-inspired bath that you’ll love.
  • Expanded Kitchens. Our kitchen addition services offer a great way to stay in the neighborhood you love while gaining the extra counter and storage space you need. A kitchen addition also adds value to your home and makes life much more enjoyable for family and guests.
  • Dormers & Second Floor Extensions. If your home has an attic you may be able to convert and add on to the area, creating a beautiful new living space. Depending on your home’s structure and township codes, this can be a great way to add space without appropriating more of your property.
  • In-Law or Guest Suites. If you need more room for additional family members, or if you have frequent houseguests, a bedroom suite offers all the comforts of home and gives everyone a nice degree of privacy.
  • New Bathrooms. Are there ever enough bathrooms? A new bathroom half-bath, or powder room addition can bring a lot of joy to you and your family. And if your home is an older one with just one bath, adding on another can increase its value.
  • Great Room Additions. Some people call it a family room, a bonus room, or a den, but whatever you call it, a great room gives you, your family, and friends more space to relax, watch movies, and entertain. Great room additions are often added off the existing kitchen to make entertaining easier.
  • Home Office Additions. If you work part or full time at home, a home office addition can be a great idea. Many people turn these additions into dual purpose rooms. For example, they may also use them as a small study or guest room. In those situations, we can design a room with built-ins that keep the “office” out of site when guests arrive.
  • Sunroom Additions. For people who want to enjoy the “outdoors” all year long, a sunroom addition can be the perfect solution. Today’s sunrooms include insulated windows and heating, making it possible to use the room in colder months.
  • And more…
Architectural Integrity

One of the biggest challenges in designing a home addition is having it flow seamlessly with the existing structure. Though a few people decide to “go rogue” and build a contemporary addition on an older home, most clients we work with want the roof, siding, materials, and colors to look as if they were always intended to be part of their home.

Because no one wants an addition that looks like a bad afterthought, rooflines, window patterns, and other materials need to be flawlessly integrated into the original structure. FD Building can design and build an addition that feels like home from the start. Our talented design team can expertly blend the old and new in both form and function, staying loyal to the integrity of your original Long Island home’s architecture. We don’t change the entire look of your house – we just make it better!
