BINYAN architecture studio
ADU Contractors in Mercer County
Average rating: 5 out of 5 starsFebruary 16, 2015
“I hired Naama Faucett to design a mid-scale 3-story office building. Naama quickly understood the program and its complexity. Working within tight site and demanding schedule, Naama developed a building layout that emphasizes the fluidity from one space to another, enhancing the required interaction between the various departments while marinating a coherent design scheme . Her aesthetics solutions and perspective in bringing light throughout the building and providing indoor-outdoor common spaces were innovative. I mostly enjoyed her attention to details and her capability to visualize the space. The end result is remarkable!”
Primiano Architecture
ADU Contractors in Mercer County
Average rating: 5 out of 5 starsApril 29, 2020
“We hired Primiano Architecture to design an addition for our house. We had no experience dealing with an architect or doing a home improvement project of this magnitude. Primiano Architecture was recommended to us by an acquaintance. From our first meeting with Joe we knew he was the right person. He was honest, intelligent and most importantly he listened and made suggestions. It was a true partnership. Joe worked closely with us throughout design, township approval, choosing a contractor and final approval. We could not be any happier with how the project turned out. I would give Primiano Architecture 4 out 4 stars and would recommend him highly to anyone looking for an architect.”

“We have worked with Karen at Brinkman for countless projects; baths, kitchens, whole-house remodels; light commercial spaces, and additions. She is a true professional and has some great ideas for the spaces we are hired to remodel. She is willing to stop by on a moment's notice for questions and advice, which is important for the remodeling that we are involved in. We plan to continue working with her for all of our remodels in the future.”

Average rating: 5 out of 5 starsMay 14, 2012
“Robie is terrific. We interviewed quite a few architects for this job. Many had great ideas and beautiful plans though they were double our budget. Robie stuck to the budget and came up with lots of great ideas. He was very flexible and creative. We'd use him again in a heartbeat!!!! We love the result and the pictures posted don't do it justice!”
Stephen Rhoads Architect LLC
ADU Contractors in Mercer County
Average rating: 5 out of 5 starsJune 24, 2014
“When we bought our 1300 square foot bungalow in 2004, we knew that a renovation was in our future. The house needed major updating and in 2006, we hired Architect Stephen Rhoads to help us with that renovation. We had interviewed another architect, as well as a designer, however, it was clear that Stephen Rhoads was the right architect for us. Stephen is extremely knowledgeable, and creative as well as being friendly. He listened carefully to our wish list, and must haves, took notes, and even drew sketches with some ideas as we spoke. Eventually, Stephen turned our 1960 outdated bungalow, into a 2200 square foot dream home. Our family room with a stone fireplace and plenty of natural light is an addition to the back of the house. Our new kitchen opens to the family room complete with granite countertops, stainless steel appliances and track lighting. Stephen designed a second floor with a Master bedroom with a spa like bathroom, and a studio with natural light. We also wanted a front porch and back deck, and better curb appeal which Stephen accomplished. He also designed a fieldstone patio, a front and back blue stone walkway, and helped us with some drainage issues in the back yard. Stephen Rhoads was able to come up with the perfect design so that we could have it all, and as the project manager, Stephen was on site every day making sure that the builder was doing their best work. We had several upgrades and change orders along the way, and Stephen negotiated with the contractor to get us the best deal possible. He also helped us get great deals on granite counter tops, faucets, lighting fixtures, and everything else that we needed to buy. Stephen is a wonderful problem solver with construction expertise, knowledge, and familiarity with the local building codes and laws. We are very happy with our renovated home, and highly recommend Architect Stephen Rhoads for any upgrading or renovation project.”

“Smart Design helped us with design and install, removing a large old gravel based driveway, and replacing with concrete. They also designed a new entryway and back patio for us. The whole process was amazing, Segev was extremely organized, responded immediately, and the finished product is better than we hoped! I highly recommend Smart 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 Mercer 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 Mercer 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.
