Introduction

I have always had a passion for construction, design and increasing home values. From my personal bad experiences with sub par contractors that take on too many jobs or has a sloppy finish, I figured our team can do better than the industry "standard". Being Japanese in this industry, we focus on laser like precision and take pride in our finish carpentry. Fast, Good, Affordable, you get to pick all three.

Hired on Thumbtack

We hired Kohei and his team for several projects, and everything turned out amazing. They completely changed the layout of our yard including a retaining wall, fence and plants. They also laid a flagstone patio, a concrete patio and assembled a gazebo at another property. They remodeled a small guest house as well. Kohei is a great communicator and always keeps you apprised of the timeline and next steps. The work is done in a reasonable time frame as well. We’ve been happy with our experience!

Kohei and his crew are exceptional. They were prompt, hardworking and finished on time. They met with challenges that came up in my hundred year old house with creative solutions. It was a pleasure to work with them and I am delighted with the results.
