“I'd give 10 stars if I could. They took on a fairly large job for me, with many moving pieces. It was such a pleasure working with this company. The workers were efficient, polite and cleaned up after themselves daily. I was given regular status updates. They even helped me sort through some of the insurance paperwork (headaches). I have recommended them, and will continue to recommend them to anyone who needs a reliable, honest contractor.”
Creative Build
ADU Contractors in Nassau County
Average rating: 5 out of 5 starsMay 2, 2016
“We engaged Creative Build Interior Design right after we started our new construction. We have been working with designer Melissa for kitchen design, color (exterior and interior) selection, vanity selection, light fixture, tile design/selection, hardware selection and etc. for the whole house. Melissa has provided very professional and valuable advice during the whole project and made our life much easier. She quickly helped us to find out our style (we often do not realize what we really like) and found something that fits our style and also in the right trend. We become more and more rely on Melissa's taste and advice. Melissa always stays on top of things and does things in the right order. She is very passionate about the work and often goes beyond the initial scope of the work to make sure that we get all the advise we need. The house turns out to be great and we reality love it! We received a lot of compliments from all the people who worked there and friends who stopped by. Everyone told me that they like the colors, kitchen, lights and everything. The house looks elegants and different from the spec houses on the market. We are thankful that we engaged Creative Build Interior Design for our new house and we felt we are lucky to work with Melissa. I would recommend their company and Melissa to my friends.”

ADU Contractors in Nassau County
Average rating: 5 out of 5 starsSeptember 21, 2012
“John from Loridon was our last bid. From the moment he looked at our plans we knew he was the one for the job. We had total confidence! It was just like the Line- save the best for last! It was a total transformation . We made a contemporary home totally traditional. All his workers were great. We felt like it was white glove service. We also were tarped for 10 days with monsoon rains. But John handled it all perfectly. Him and his team are all extremely talented. Not only did they build us a beautiful home but their detail with azek is beautiful! We are just about to rip out our existing sidewalls on the inside staircase and add a railing and moldings and because it Loridon we have total confidence. We would have total confidence to recommend them for any size job - because it will be aggravation free! Also- John has Diana who is the go to person for all your needs. She is amazing and a real take charge person! We couldn't have been happier with the workmanship and all the workers! My husband was expecting this construction to be a nitemare and it was just the opposite! It was a grea experience Again ... we couldn't be happier! Again- we owe it all to John from Loridon planning and design!”

An accessory dwelling unit (ADU) is a separate living space that can be added to your property. It functions as an additional dwelling on the same land where your main home is located. ADUs have their own amenities and entrance, providing a self-contained living area. Unlike a traditional home, an ADU cannot be sold separately and is considered part of the same property.

ADUs are subject to specific zoning regulations and building codes in Nassau County. These regulations determine where and how an ADU can be constructed, ensuring compliance with local laws and requirements. It’s important to consult with local authorities or a professional contractor who is familiar with ADU regulations in your area to understand the specific legal differences and ensure your ADU meets all necessary criteria.

Consider these options for cost-effective ADU:
  1. Prefabricated ADUs: Affordable and easy to assemble, they’re a practical choice. Many prefab ADUs cost under $100,000.
  2. Traditional Construction: Work with an ADU contractor to find budget-friendly options and make smart choices.
Tips for cost-effective ADU construction:
  1. Define your needs: Determine the purpose of your ADU, whether it’s for family, rental income, or a home office.
  2. Consult a contractor in Nassau County: Their expertise can help with cost-effective materials, designs, and planning.
  3. Prefabricated components: Consider using prefabricated elements like cabinets or bathroom fixtures to save time and money.
  4. Explore financing options: Look for ADU-specific loans or programs to help cover costs.
Ensure compliance with local regulations and seek professional advice. A knowledgeable contractor can make the process smoother and cost-effective.
