Testimonials

Some words from our clients

We worked with Pat in the renovation of our four story, 3900 sq ft home. We were immediately attracted to Pat because, unlike the architect we had hired, Pat listened and got to know our tastes/desires before helping us develop a plan.

Stephen H.

You've completely transformed our house in a way we never would have conceptualized. The entrance to the living room, dining area and kitchen are completely open instead of the clutter of closets, chest and kitchen walls, so that the view over the valley and hills toward Mystic and beyond now dominates the house, instead of being half hidden.

D & P

We appreciated your dedication and guidance in helping our vision come to life. You went the extra mile and have so many talents – thank you for putting such effort into our project. Your business card doesn't lie, you do draw pretty pictures, but the best part is that you turn those pictures into reality!
