"Basic Concept designed and built a deck in our back yard and did an entire kitchen remodel for our home.

All of the workers that came to our home were very skilled, polite, and professional. They made sure that all work was done completely and correctly, no shortcuts. Charles was very involved in every aspect of the project. He is a great communicator and coordinated all the work and deliveries very efficiently.

"We could not be happier with the work done by Wyatt. He took time to listen to what we wanted for our project and explained the process and answered any questions we had along the way. Our project was turning a partially finished basement into a family room/office and a Pittsburgh potty into a half bath. His attention to detail was incredible. He did a great job matching the new walls with the existing walls swirl pattern and the baseboards look great. The bathroom turned out better than we could have imagined it. Wyatt also stayed within our budget, so there were no surprises at the end. We could not have been luckier in our search for a contractor and would highly recommend."

FAQs for addition to existing structure building service projects in Mckeesport, PA
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.
An in-law suite is a self-contained living space attached to—or detached from—your main home. Expect a bedroom, full bath, and a kitchenette or compact living area. The setup gives relatives privacy, doubles as a potential rental, and can lift your property value. To qualify as a legal dwelling, the suite must meet local building codes and zoning rules.
