"Pierre construction is Awesome!!! If you’re looking to have someone to do your next project, look no further. I spent quite a bit of time interviewing and getting quotes for a major 2 story deck project for my house which included some intense structural improvements to my house as well, since some of the existing columns where in tough shape. I’m so glad that I picked Dave Pierre and his great crew to do this for me! Dave’s price was very reasonable and he was very much on top of all details. He bent over backwards to make sure that I was happy with every step of the project. His crew of over 12 years was also very skilled and often had discussions about challenges to make sure the details where the best that they could be before proceeding on the the next phases. As you can see from the attached video of the 2nd floor, the results are fantastic and I’m enjoying my new space immensely. "

The Narrow Lane Company is a full service landscape company dedicated to creating and maintaining beautiful outdoor spaces you'll absolutely love! All work is done in a timely, professional manner and 100% guaranteed.

"Worst experience working with a contractor we have ever had. Lack of communication was astounding. Reached out to start the project on our tiny front lawn in June/July. Didn't start planting until mid October. Was told there were 5 jobs in front of ours. Ignored photos of exactly what we wanted. Finish product is passable at best. Would not recommend."

FAQs for addition to existing structure building service projects in Worcester, MA

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.
