A home addition isn’t just about adding square footage. It’s about creating a space that improves how you live every day.

EXCELLENT Based on 18 reviews Thomas Aldridge2025-04-07Trustindex verifies that the original source of the review is Google. Woodbine was awesome! Alex and his team were excellent in every way. They were always there when you needed them and were creative in offering ideas/suggestions for the bathroom. Used Alex for several other projects as well which came out excellent. Alex is our guy now. Will not use anyone but him. Parker DiNatale2025-04-07Trustindex verifies that the original source of the review is Google. I had the pleasure of working with Alex and Woodbine Design and Build for several home upgrades, and I couldn't be happier with the results. Alex is incredibly thorough, attentive to detail, and committed to delivering top-notch work. He helped transform my builder-grade townhome by adding custom features like a beautiful built-in fireplace, fully renovating both bathrooms, and upgrading the flooring from carpet to stunning hardwood. Additionally, Alex coordinated the design and installation of my countertops. From start to finish, he was there every step of the way, making the entire process seamless and stress-free. I highly recommend Alex and Woodbine Design and Build for anyone looking to elevate their home with quality work and exceptional service. Brooke Hart2025-03-27Trustindex verifies that the original source of the review is Google. My husband and I moved into a builder grade home we wanted to make our own and cannot recommend Woodbine enough. Every step of the process was easy, reliable and you can truly see the pride in the workmanship. We swapped out floors in two stories of our home and replaced a lot of the builder grade materials in our kitchen. The timing was great and communication along the way even better. We could not be happier with the results, especially of our kitchen upgrades, before and after photos attached!! If you’re considering using any company, look no further! Nicole2025-03-01Trustindex verifies that the original source of the review is Google. Alex installed custom cabinets on the sides of our fireplace and we absolutely love it! He helped us with the whole design process and we could not be more pleased with how it turned out. He works quickly and produces quality work. We will definitely be using Alex and his team for future projects. Christine Bell2025-02-14Trustindex verifies that the original source of the review is Google. Alex and his team were great.

We are so pleased with how our bathrooms turned out and get compliments whenever guests come over. MA Spagnuolo2024-11-19Trustindex verifies that the original source of the review is Google. Hired Alex to build a custom builtin for our bay windows with storage under it. Came out great and only took him two days from start to finish. Will have him do more custom builtins for us.
