Prominent Builders & Design LLC
ADU Contractors in Mahwah
Average rating: 5 out of 5 starsJune 29, 2012
“This was our second time working with the amazing team of contractors, project managers and designers at Prominent. They had previously done a spectacular job refinishing our basement (beams, bedroom, bathroom, storage, Martha Stewart mudroom, you name it). We were expecting twins and the need to expand our house was imminent. Our house is a hundred year old arts & crafts house so maintaining the integrity was essential. And being on schedule! We renovated our kitchen into a kitchen/great room area which therefore doubled our master bedroom and master bath located above. In addition, we created a bar room space where our former EIK was located and renovated our powder room. Lastly, we finished our third floor to be a guest suite with the most incredible bathroom ever. In addition, we added a new deck with under decking materials and had to rebuild stone walls-- I had no idea just how gorgeous this could be. A deck is not just a deck. The end result is nothing short of spectacular, extremely tasteful and maintained Arts & Crafts integrity although my husband and I were adamant that although we liked the linear style and functionality of A&C, we did not like the "darkness." Prominent stayed within our budget unless my husband and I personally strayed afar. They advised us when aesthetically we could all make a better choice. They were available 24/7, literally and if we had even the smallest emergencies, someone from Prominent was in our home immediately. I also love that Promiment Design factors into every project. Having Traci to literally help us with the tile work, cabinetry, paint colors, furniture layouts, the babies' nursery was such a wonderful finishing touch. Our home would not be the same otherwise. I am really not being overly sensationalistic here. We have truly had an amazing experience working with Prominent and having to live out the end of my pregnancy in my basement, and the first two months with twins, 2 big dogs, baby nurse and so forth down there, they did everything possible to expedite and keep us very comfortable.”

Beforehand, I had very little knowledge of cost or labor, but he waled me through the process, and the kitchen was done in a tremendously timely manner. Patrick McHugh is a knowledgeable member in the professional field; he is competitive, communicative, and he sincerely works to provide the client with a high- quality end product.”

“I have on several occasions hired architects-designers, but Bob stands out head and shoulders above everyone. Bob listens carefully to your needs, and brings extensive expertise and creativity to his work. Bob created a new walk-in closet for us, and we ended up with a result that exceeded my vision for it — and well within budget.”

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 Mahwah. 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 Mahwah: 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.
