    Featured Reviews for ADU Contractors in O'Fallon

    Prime Designs by Nancy
    ADU Contractors in O'Fallon
    Average rating: 5 out of 5 starsFebruary 14, 2018
    “I have used Prime Designs by Nancy for projects at both my office and my home. Nancy did the total design work for my office when it was built 6 years ago and I hired her to remodel my home "man cave" which consisted of a new bar, game room and media room. Her work is outstanding! She is creative beyond my expectations and ran both projects from beginning to completion while keeping me in the loop every step along the way. I highly recommend Nancy's work and I will use her again!!”
    Dana King Design Build Remodeling
    ADU Contractors in O'Fallon
    Average rating: 5 out of 5 starsFebruary 6, 2013
    “I enjoyed working with Dana as she helped reconfigure my space into something I had never even imagined a couple years ago. Her resources are professionals who do the job right AND are decently priced- hard to find these days. She has lots of great ideas, but as long as you tell her upfront what your budget is she will stay within your parameters. We are in the process of fixing up a house and have asked her to help with this project too. Already so excited!”

    ADU Contractors in O'Fallon
    Average rating: 5 out of 5 starsFebruary 9, 2014
    “Donna, Allan, and their architectural support team are amazingly and refreshingly personal, creative, professional, and responsive. They were able to take an old 70s ranch with all its oddities and convert it into a new craftsman style home. They listened carefully over many conferences to come up with a creative design, worked within our budget to get us what we needed, revised and revised patiently to get it perfect, and then followed up with on the job supervision and sometimes substantive changes on the fly, including invaluable help with the governmental review process. They all worked so well with our construction crew, who had their cell numbers for on the spot questions about plans or problems, of which, one can imagine, there were many. Thanks to Donna's architectural design (the neighbors are truly in awe of the front elevation and interior transformation), Allan's meticulously drafted plans (the city review board and fire teams said they had never seen such meticulous detail), and the respectful collaboration with all involved (we are all still talking to each other after what ended up being a tedious, four year project), we now have the transformed home we wanted when we started: solid as a rock and nearly soundproof, aesthetically consistent with the older parts of the house, and the openness, light, and functionality of a new home, even if it all drove Donna and Allan crazy sometimes trying to get it for us! They did it all with a smile, and with exceptional professionalism. They certainly went the distance for us, and are just an awesome team. They have my highest recommendation as an architectural firm.”
    Stockell Custom Homes & Construction
    ADU Contractors in O'Fallon
    Average rating: 5 out of 5 starsFebruary 16, 2015
    “Stockell Homes/Don Stockell has been the general contractor for us on 2 homes. Don completely renovated every square inch of our former home, a 1902 gem (after his renovations!) in an urban setting. We moved this past Summer to a suburban 1980's home and undertook major renovations on it. We have received nothing but the highest compliments from all that have entered either of our homes. Don's attention to detail and craftsmanship are superb. He has a fabulous work ethic and his word is his bond. With all the work he has done for us we feel like Don is one of the family and we recommend him without any reservation to anyone who is ever looking for a contractor.”

    “Drew is always professional, on time, and excellent at giving advice based on his eduction and experience. Most importantly, he's an excellent listener and provides multiple options based on the scope of work. Not to mention, his prices are unbeatable. At this point, I don't even look elsewhere because he's my go to guy. We've worked with him on multiple residential rehabs where tight spaces were involved and creative rearranging needed to happen. Of course, he made it happen!”

    Benchmark Custom Homes, Inc.
    ADU Contractors in O'Fallon
    Average rating: 5 out of 5 starsMay 30, 2014
    “We worked with Benchmark homes on a custom home project. The job site was always well run and clean. We were impressed with the trim work details and the care in which they protected the home when the subs were there. The design and finish work was exceptional. The home truly is beautiful. The project manager and builder were always readily available and responsive when we had questions.”
    Art & Architecture Inc
    ADU Contractors in O'Fallon
    Average rating: 5 out of 5 starsMay 1, 2014
    “We've had a series of major renovations on our home and Mark has done the design/drawings for each phase of construction. We gutted a basement that required lowering the floor to get better ceiling height. We added a master bath/laundry upstairs. And most recently, we redesigned our kitchen and added a family room and office off the back of the house for a more open floor plan and additional living space. Mark did an excellent job of keeping the design in line with the look of the rest of the house, but the floor plan is more open which is hard to find in older homes (ours is close to 90 years old). We have loved the new addition and Mark did such a great job of figuring out what we really wanted and making it all work. I would highly recommend Mark for your next renovation or new design project!”
    Bower Leet Design
    ADU Contractors in O'Fallon
    Average rating: 5 out of 5 starsJuly 20, 2018
    “Susan Bower did an outstanding job as the architect for the remodel of our condo at Lindell Terrace in the Central West End of St. Louis, MO. We purchased our condo for many reasons but one of the principal attractions was that this particular building allowed us to easily take down walls to open up the space and redo the layout to our liking. Susan was instrumental in helping design the perfect home for us. She started by trying to understand our vision and then offered alternative designs that took our initial thoughts and translated them into the clean, modern, practical, beautiful and elegant look we wanted. The use of lighting, something we had not focused on, was a creative way to enhance the space and give it a perfect atmosphere. Also, her vision on how to use all the space (where to put doors and where to move walls) was simply the best use of the space to achieve our goals. Besides her talents as an architect and designer, Susan demonstrated professionalism, competence and an ability to relate to people. Her communication skills and construction knowledge were evident when she was asked to help find solutions to construction related issues. She has been a pleasure to work with in all facets of the project and we highly recommend her for her design skills, her people skills and most of all her ability to take our vision and implement it adding her own spin to make it the perfect home. Jim and Vicky Zimmerman St. Louis, MO”

    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 O'Fallon. 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 O'Fallon: 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.
