“I worked as a general contractor with id8bau on two remodel projects in San Rafael and San Francisco respectively. Matthias was very responsive and collaborative, it was a pleasure to work with id8bau on these jobs. I would recommend them highly.”

– David Gordon, General Contractor, San Rafael, CA

“id8bau was hired for a new location study for parts of our research facilities and we really enjoyed working with Matthias and Felix. Their process and communication was very professional and efficient, and the final report was well received. We would be very happy to work with them again.”

“We hired id8bau for our remodel project in San Francisco and really enjoyed working with them. Matthias and Felix were professional, great communicators, always on top of things and easy to work with. id8bau accomplished an-over-the-counter building permit which allowed us to start the project in time, and they worked with us on strategizing a more complicated planning permit. I would recommend this firm highly.”

“Matthias worked as an architect on our house addition and remodel. We really appreciated his patience, professionalism and responsive communication. He and his business partner easily maneuvered the alteration of our existing ranch style house into a modern metal-clad one through all design, permit applications and permit hearings, and he did a great job supporting the construction process. We are working with id8bau now on a carport for our house.”

My wife and I hired Matthias Troitzsch of id8bau, for the purchase and installation of a European front door/side window unit. Matthias took responsibility from start to finish, in counseling us and determining which door to order, what features we might want, what colors, and how to get it to our home and how to get it installed. It is a Pirnar door, manufactured in Slovenia; and, while it is incredibly beautiful, high class and high tech, it is not something which local contractors know how to install. So, what could have been a very difficult task was made much easier by Matthias. He was extremely available, helpful and can-do, from start to finish, both in the decision and ordering of the unit and in its installation. His judgment was invaluable at every step, and we are delighted with the result. My wife and I recommend him very highly and without reservation.
