**★★★★★ — tim hudak, Nov. 2020**

> The owner, Keith, was very professional and helpful with our recently completed project for an in-law suite addition. The biggest advantage I think we had from working with him over other options were his superb design ideas and recommendations to provide us with options that would work within our budget. Additionally, we had a difficult corner lot where he had to work creatively to maximize our use of space within the building setback distances.
>
> Our project did take a little longer than originally anticipated, but it was mostly due to availability issues caused by COVID-19. There were no major items that required re-work, and any small quality issues we pointed out were taken care of without any further discussion.
>
> Keith is not the cheapest option out there, but I have no doubt that we saved countless headaches and change-orders by working through him via a design-build style contract. You may agree to a slightly higher price up front, but it saves you in the end over going with a lowest bid contractor.
>
> After it's all said and done, I would definitely work with him again if we have any other major renovations on our house.
