Featured Reviews for ADU Contractors in Alton Bay

KBS Contracting
ADU Contractors in Alton Bay
Average rating: 5 out of 5 starsJuly 25, 2018
“Kreg did two projects for me. Both involved repair of an old house that had extensive structural rot. He did an excellent job in both cases restoring the house to like new condition while controlling costs. I would definitely engage him for future projects”
Full House Home Improvements LLC
ADU Contractors in Alton Bay
Average rating: 5 out of 5 starsFebruary 6, 2020
“I had Rob finish about 700 square feet of my basement. We relied heavily on his input and are thrilled with the results. Rob gave me an upfront cost and stuck to that cost throughout the process. I’d definitely recommend Full House Home Improvements.”
KOAL, PLLC
ADU Contractors in Alton Bay
Average rating: 5 out of 5 starsSeptember 7, 2019
“Don Bladja and his team at Koal PLLC have provided remarkably professional and creative work product for our home development efforts. It has been a joy to see our vision unfold with Don as he deftly works with our builder, his structural engineering partner, our cabinet maker, and others on our complex project. He has taken a very rough plan, started by another architectural firm with which we were unsatisfied, mixed in quite a number of unique and complicated requests from us along with forbidding site restrictions and has turned it into a detailed set of drawings that has "wowed" all with whom we have shared. Our builder and his tradesmen have easily implemented our shared vision straight from Don's plans. Many of our complicated requests, including a float room, sauna, elevator, and golf simulator/theater/business conference room combination (to name just a few) started as simple ideas scribbled on a napkin. With Don's expertise and experience, he quickly showed us many alternatives; turning our crazy simple sketches into detailed plans that worked within our uniquely challenging house footprint. It has been an absolute pleasure working with Don and his team. We only wish there were more than 5 stars to rate Koal PLLC, so you would more fully understand how impressed we have been!”

D. A. McCullough - Designer - Builder
ADU Contractors in Alton Bay
Average rating: 5 out of 5 starsApril 21, 2018
“Dave is an exceptional designer and builder. His knowledge and execution of a plan are professional, accurate and completed with integrity. His talents as a designer and hands on builder are remarkable. His versatility in his abilities to design and build traditional homes as well as more modern-style homes of every size is impressive. I am convinced he can do anything! I found Dave to be patient, kind and trustworthy. He was always willing to hear design ideas and take things out of the box when I wanted to while keeping me within the box when I needed to. He only uses respectful and skillful crew memebers that appear to be loyal to him and admired by them.. I have never felt in better hands with the most important financial and emotional project of my life. I would do another project with Dave in a second! -Julie and her dog Novia”

M&M American Builders of NH, LLC
ADU Contractors in Alton Bay
Average rating: 5 out of 5 starsDecember 1, 2022
“M&M American Builders are a very professional company. My wife and I own a ranch style home. In the kitchen she wanted a double window to be removed and a door. She wanted it replaced with a sliding door. John & Keith came in and reconstructed the entire back wall of our kitchen to accommodate her vision, and let me say they did just that. We are told over and over again how much this has changed the look of our kitchen from the natural lighting, space and above all the quality of work done. They were very helpful and when leaving they left everything spotless inside and out. If you ask for something to get done M&M American Builders of NH will deliver just that.”
Bonin Architects & Associates
ADU Contractors in Alton Bay
Average rating: 5 out of 5 starsAugust 9, 2012
“"My wife and I had pursued several options as we developed a plan for our home. In many cases we were frustrated with the input we were receiving, so we began looking at timber frame plans because of their openness and creativity. It seemed that an architect familiar with timber framing had a special eye for the type of features we were looking for in our home. We contacted them and we were pleasantly surprised when they informed us that they were happy to assist in designing a home that accommodated our needs. We were frustrated because we had general design ideas but couldn't put it all together and needed the creativity of an architect. Bonin Architects did a wonderful job in working with the best of our ideas. They assisted us with difficult site issues and we are now able to go forward with the construction of the home confident the home is filled with our ideas and their expertise.””
Great Northern Builders, Inc.
ADU Contractors in Alton Bay
Average rating: 5 out of 5 starsMarch 10, 2016
“We had Great Northern Builders completely finish our large basement, and Len Bogh did a great job. I never thought we could transform that basement into such a comfortable living space. My husband, who recently retired, is now putting his home office down there and he loves the space. It is also great when we have all the family staying here over Christmas. We can sleep 4 or 5 people down there.”
Crossroads Contracting, LLC
ADU Contractors in Alton Bay
Average rating: 5 out of 5 starsDecember 15, 2016
“After a year of searching for the right people to replace our attached carport we were happy to find Crossroads Contracting. From the first meeting with the project manager ( Nick), we could see that this was going to be a positive experience. Nick worked with us to design something that was both structurally superior and surprisingly affordable. In fact, we were so impressed with the workmanship that we hired them again a few months later to replace our porch. If you are looking for quality work at a competitive price , then look no further. Our thanks to Nick, Crystal, Johnny, Shaun, Barry & Jim for increasing both the comfort level and the value of our home. We know who we will be calling for any future projects!”

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 Alton Bay. 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 Alton Bay: 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.
