Timson Builders, Ltd., has been helping homeowners and businesses in Chester, Delaware and Montgomery counties realize their dreams for over 30 years. Whether the job is a small specialized residential renovation or a major commercial construction project, it will receive the same attention to detail and budget. As fully-licensed and insured on-site general contractor, we manage a team of skilled, professional subcontractors who understand our commitment to the highest quality craftsmanship. Our reputation for exceeding homeowners' and architect's expectations has resulted in a legacy of referrals and satisfied customers. Let us meet with you to show some examples of our diverse portfolio and talk about how we can help you realize your construction goals.

"We found Stan on Angiâ s List for a remodel of our unfinished basement and we were impressed with his knowledge, his ideas, and his commitment to doing quality work. When we first met, we told him that we had a baby on the way and were working with a tight window to hopefully complete the project before the baby was born. We hired him and we knew that we made the correct decision because he was determined to make that deadline (and he did). Stan also worked with us on our budget and helped us cut where we needed to in order to make our dream basement come true. He handled all of the permits and talked with the borough for us so we didnâ t have to deal with that headache which made the process so much quicker and easier. That was very important to us. Lastly, even though our project was smaller in comparison to what he normally does, we didnâ t feel like he cared about our project any less than others. The commitment and care did not go unnoticed. Thank you Stan for making our basement beautiful for our new family. Highly recommend!"

"We bought our house in June of 2024 and hired Joe/All Phase to complete a full house restoration. The house was built in 1870. Each person that worked on our house over the course of 4 months was exceptionally professional. We received compliments from our new neighbors as the project progressed and about the team from All Phase that handled each phase of the project. Joe Stillman was quick to respond each time we reached out to make a modification or just check in. He was regularly on site to ensure expectations were met. We had walls removed, added insulation, a full house electrical rewire, dual zone HVAC install, walls removed, windows installed in walls that had no windows, sliding glass doors installed where there were no previous sliding glass doors, house fully drywalled and painted, all new woodwork, new roof, new siding and new downspouts. They also built a portico. I would highly recommend Joe and his entire team. We also had a garage built this year that I?ll review next."

FAQs for addition to existing structure building service projects in Malvern, 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.
