"Francisco Garcia did an excellent job finishing our basement. The work quality is excellent. The communication and flexibility throughout the project was excellent. The project finished on time within budget with zero surprises. Any concerns that arose were addressed expeditiously and professionally. I highly recommend Colorado Paradise Builders for your next project. The building inspections were coordinated by Colorado Paradise Builders and passed easily. We learned while talking to the inspectors that we had a gift by using Francisco as a general contractor. They mentioned other people in the business may not provide the level of customer service and professionalism which Colorado Paradise Builders demonstrated on our basement finishing project. I could not be more enthusiastic with a recommendation."

"All I can say is WOW! We hired HWG to re-do our rather dingy, dark and unspectacular basement. Briana and crew were so very kind helping us reimagine our circumstance and make it a reality, an unimagined dream come true. Light, welcoming and now... maybe the showplace of our home? We'd feared having to deal with a lot of noise, dust and the like and what a great surprise! The crew was courteous, friendly, considerate and, guess what! They finished ahead of schedule and a little below budget. Along the way, I suppose like most people, we decided to make changes here and there. HWG took this all in stride and embraced our suggestions / preferences as work progressed. Delightful people. Incredible work and what a fantastic result! Thanks, Briana. Thanks to all the folks who transformed our basement. HIGHLY RECOMMENDED! Simply the very best. We just wish there were 10 stars to award. ð"

"Ben Muck of A & M Landscaping turned our backyard into a sanctuary. It is now my favorite place to be, in or outside of my house! Whether for socializing, or recharging alone, Ben created spaces that are comfortable, functional, and beautiful. He was easy to work with, pleasant, informative, and professional, and delivered above and beyond all we had hoped for. Our backyard renovation was especially important to my husband and me, because this is our first house, and it was inheritance money from my grandparents that provided for the project. I told Ben that it was at their house as a child that I learned the joy of â visitingâ with loved ones outside. Ben designed a space Grandma and Grandpa would have loved, and I am so very grateful."

Addition to existing structure building services FAQs

Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take. 

Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements.
