Creative  •  Thoughtful  •  Design


The world is full of imagination. Let it inspire, reconnect, and lead the way.

Good design is not a one size fits all solution and the first answer is rarely the best one. It is a process of understanding the client's needs and the environment they have to work with. I strive to help my clients understand what it is that they truly want, and then help them make it a reality. 

Have you ever wanted to improve the quality of your life by changing your environment?

I am a General Contractor and an Architectural Artisan who specializes in designing and building well thought out spaces for residential or small commercial projects.

What is "Dioxua"? (dee-o-shua)

After spending time living in Brazil during high school I grew used to the mispronunciation of my name, Joshua.  Phonetically in Portuguese it was spelled Dioxua. Years later I realized that my environment in Brazil had given me a fresh perspective on who I am. Now, I hope to help you discover a fresh perspective on your design needs.
