Factor Design Build
ADU Contractors in Thornton
Average rating: 5 out of 5 starsMay 12, 2016
“Factor Design Build is the type of reputable company that makes things happen. In the world of construction, there are always challenges and deadlines. This team of professionals has a great ability of pulling together their resources to take action quickly. They take problems and turn them into opportunities that work well for the construction team, design team and home owner. I will continue to work with this team as they create beautiful, thoughtful and creative design projects.”
Natural Construction
ADU Contractors in Thornton
Average rating: 5 out of 5 starsJune 11, 2013
“Natural Woodworkers completed a full remodel of our home including exterior and interior elements. We enthusiastically recommend them! They gave us a new kitchen, bathrooms, hardwood floors, tile work, custom cabinets and all the details perfectly done to my wife's quite exacting standards. Let me also mention the pergola, siding and important fixes our 40 year old home needed. Now our home is like new. The former owner drove by one day and begged us to give him a tour. He was so impressed that he pleaded to have us show it to his wife later that day! Aside from the excellent work these craftsmen do, you will find they are just plain great people. We actually missed them when they were finished. I whole heartedly recommend these guys. Come see my place if you think I'm exaggerating.”
Savignon Interiors
ADU Contractors in Thornton
Average rating: 5 out of 5 starsAugust 3, 2015
“Gabriela went way beyond the call of duty to help my husband and I pull together the remodel/interior design of my home in 2 months. I had a contractor but we needed help to choose tile, paint, draperies, faucets, tub, lighting fixtures and more. She also gave us contact information to find a great electrician to install new lighting fixtures - sconces, chandeliers, and many recessed lights to brighten up a dark home. We met at stores and showrooms. Gabriela met our deadline, gave us suggestions but is a great listener and always supported our decisions.”
Hive Architecture By Becky Alexis
ADU Contractors in Thornton
Average rating: 5 out of 5 starsJanuary 31, 2014
“From start to finish this was an amazing experience. Becky listened to all of our input and took all of our wants and needs into consideration. The project came in under budget and ahead of schedule and the crew doing the work were fabulous. We will be using them again on next major project! Our house was built in 1910 and they did a great job of incorporating the character and charm into the project! Couldn't be happier!”
Paramount Remodeling
ADU Contractors in Thornton
Average rating: 5 out of 5 starsMarch 8, 2021
“Levi and his team are exceptional at what they do! As an Interior Designer, I have worked with many builders, and have been blown away by the final product. I hand over floorplans, space plans, finish plans and everything in between and they execute it as specified, or contact me when suprises arise. I appreciate the specific attention to detail, excellent communication and completion of a job. Their work is always to the standard of my clients, and their team is always friendly. They finish a project with the same "gusto" they start a project, which is another thing I see among other trades I have worked with in the past. I highly recommend Paramount. Thank you Levi and team for always bringing my ideas to reality for my wonderful clients.”

Built by Krueger
ADU Contractors in Thornton
Average rating: 5 out of 5 starsFebruary 9, 2016
“It is clear to all of us here at Green Landscape Solutions, that Built By Krueger is one of the best general contractors in the Boulder County area. We’ve had a strong business relationship with this company for several years. During that time we’ve found that Kruegers excel at communicating with their clients and subcontractors. They outclass their competition by a wide margin; by paying attention, providing an excellent value for their work, and demonstrating a commitment to providing the best customer service.”
Forward Architecture, LLC.
ADU Contractors in Thornton
Average rating: 5 out of 5 starsJuly 24, 2020
“I pretty much knew want I wanted to do with my project. I warned Ellen I knew enough about architecture to be dangerous. Ellen recognized my requirements and was instrumental in identifying other considerations needed for the project. Included was a need for a code variance (setback). I was informed by the city, before starting the project, a code allowance(variance) was not required. Ellen’s code research was right. A code allowance was required. With her help, the review board approved the code allowance request unanimously. Our project involves bumping the attached garage eight feet to allow for a utility room between the garage and house. The design includes moving the washer and dryer out of the basement. As simple as the project sounds, there is a lot involved. Ellen listened to my wife’s concerns and ideas on the project. Together we achieved a very efficient design. We are now in the permit and construction phase of the project. I am looking forward to Ellen’s input. Ellen deserves your serious consideration.”
Helios Design Group
ADU Contractors in Thornton
Average rating: 5 out of 5 starsFebruary 28, 2014
“Home renovations are extremely stressful - especially the renovation of a diamond-in-the-rough hundred-year old house in a neighborhood with many fine examples of well-preserved hundred year old houses. I looked at the result of several renovations before hiring Carol - what was obvious in her work was a deep understanding of the technical challenges as well as a love of understated, elegant design and an eye for detail. I made the right choice. Carol's sensitivity, approachability, and unflappable resolve rescued the project. The architectural elements that Carol recommended have drawn admiration in the neighborhood, without overwhelming the original character of the house. Mission accomplished”

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 Thornton. 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 Thornton: 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.
