Construction and Remodeling company that services both Commercial and Residential customers. We are licensed and insured.

"Our house addition project has been 3 years in the making. Not by choice! We have met with right around 10 contractors through this process. Not just messages or phone conversations, but met directly. Some of these companies never got back to us and some were just astronomical regarding pricing. In the end, we met these professionals, Magic Designs, and had an AMAZING experience working with their team. Communication was spot on, with constant updates that were concise. If I had a question, they were on it and very responsive. Their crews were professional and conducted high quality work. They worked on our project consistently 5 days a week and 7 days a week if and when needed. The final product, AMAZING! These professionals delivered a great product and did it at the exact calculated time. "

"Jim and Danielle help me take a room that was old-fashioned and in need of a remodel into a space that is very warm and inviting. With his guidance on the day-to-day work and his ideas for how to design the space, he was a valuable resource for me through the process. He gave me lots of ideas and choices from flooring to fixtures. As the crews that came into the house were friendly and considerate of my privacy as I work from home.

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. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite.
