Called ecobuild architects on a short notice they came and help us . Highly recommend.
I was working with a friend on a remodel design and our city planning department was being a bit difficult. Our contractor recommended Courtney at EcoBuild to help us finish our plans. Courtney and Amalia picked up our project and created something we really like. This is a small addition to update the look of the house and enlarge our garage for hobby and storage space.
They always welcomed suggestions and were quick to respond to my needs or the things the city brought up. The project cost was very reasonable. They kept it within our budget for the whole project.
I highly recommend EcoBuild and if we ever need a new addition or modification, Courtney will be our first pick.

Eco Build Architects was out there within hours of my call walking through the home, coming up with a plan of action and taking measurements. Within days we had a comprehensive plan submitted to the city and a quick approval.
I can't recommend them enough for your architectural needs.
Thanks 🙏 again. I owe you one.

Courtney and his associates did an excellent job with our project. The project was very detailed and needed someone that exemplified the same. Courtney exceeded our expectations at every level. He handled not only the design work but also took on the project manage work coordination with the city when the other firm failed.
We expect to see Ecobuild Architects again soon on our future projects.

I worked with Courtney for a smaller commercial project under a pretty pesky time line. He was good natured, professional and knowledgeable. Delivered his drawings on a reasonable deadline, and without issue. He was open to feedback, and creative in his problem solving and approach.
