★★★★★

Their design abilities far exceeded our expectations!

We hired Sennes to add a 1/2 bath within the existing footprint of our home. They opened up our floorplan and created a brighter, much more open area than we could have ever anticipated. We found the team to be professional and always available for a call, text, or even a visit when we had ideas or questions. They also went above and beyond to find an exact match for our existing tile to ensure the new bath looked like it had always been there. We appreciate Sennes’ time and commitment to our project—thank you!”
