Thornhill Design Studio did an outstanding job…

designing a beautiful and practical kitchen renovation for our center hall colonial home in a historic neighborhood of Baltimore. Tina and Doug took the time to understand what we wanted to achieve with our renovation, and created a plan that met all our needs. They are a joy to work with. We can't wait to hire Thornhill Design Studio again for the next phase of our home renovation: an amazing backyard! I highly recommend Thornhill Design Studio!

Tina and Doug McCoach are a great team of architects.

They do wonderful work, particularly in historic districts where sensitivity to designing new and compatible building elements is critical. They are also very quick to see creative solutions to problems with existing flow patterns that are critical in livable design. I would recommend them highly.
