"Aventus completed a 1600 sqft 2bedroom 1 bath addition (in-law suite)for my home. Communication was excellent. The project manager Brianda worked closely with me throughout the project. The permit process is very lengthy and we had some material back order delays but the process overall was timely and I couldn?t be more pleased with the outcome."

Brown's Construction, Inc., provides the highest quality work at an affordable price. We listen to our customers needs and we execute their ideas to near perfection. Customer satisfaction is our number 1 goal!

"Great work when it is done right, but some mistakes should not be made. To completely frame the whole build crooked and have to tear down and rebuild is ridiculous. I am still dealing with water leak issues from the build. There were other projects i had planned for them, but I have had a change of heart. "

"I have had numerous people and companies out over the years for various projects but CustomHome Medic was without a doubt the best company Iâ ve worked with. First Russ came and assessed the problems . I had years of water damage under the kitchen sink and was now affecting the floor. They replaced the floor and even attended to other issues such as a water line that other companies had merely zip tied. They were very precise and attentive to every detail. They also adapted to changes in the original work order. Replacing a threshold, adding a deadbolt and moving my ceiling light-Twice ! They replaced all the doors upstairs with regular, bi-fold and sliding glass. This was a repair from a previous botched job, but Larry and Chris made sure they fit perfectly. They really have a lot of pride in their work and it shows. The final project was a tearing out and replacing a shower. Russ provided me with 3 price points to help save money and a tons of options. It is absolutely Stunning. !! I just love how beautiful it is. When I selected tile we found out it had been discontinued and Russ went above and beyond to find some just like it. Larry made sure that the giant hole in my family room from the shower water damaged was repaired to look like nothing ever happened. Larry and Chris are very skilled and great to work with. The owner Adam was onsite frequently and actually did my shower because the guys were busy with another job and he didnâ t want me to have to wait a week until they finished. Really so so glad I called them. Told my daughter about them and she is having all new flooring and kitchen remodeling done. Everyone did their absolute best to make this a well-done and stress-free experience. I Other estimates were thousands more and included work that Russ told me most likely did t need to be done. Honest and reassuring. Also had Larry and Chris remove and replace all the upstairs doors and install new glass sliders, bi- fold and regular doors that instantly updated the look in all the rooms. Again, work was started on time, completed when promised and done the right way. Unlike the previous workers I had hired. The final Project was the most involved. Tearing out and replacing the upstairs shower. Russ gave me estimates with 3 different price points to help me save money. Again, even the highest one was less than 2 other well-known restoration companies quoted me. There was such a wide selection of materials"

FAQs for addition to existing structure building service projects in Fishers, IN

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.
