I would like to briefly introduce myself:
I'm Diego Bernal A.,
Design Consultant and Owner of DBA Design & Drafting.
I bring nearly a decade of experience in environmental, structural, and architectural design, with a primary focus on residential projects such as custom homes and cottages, as well as select commercial buildings. My goal is to guide clients through the design process by transforming their ideas into practical, well-designed, and buildable solutions while maintaining a strong emphasis on quality, comfort, and efficiency.
I hold a degree in Architectural Technology from Fanshawe College and have gained valuable experience working with engineering firms and building inspection departments. This professional background provides me with a thorough understanding of building code compliance, construction best practices, and efficient building design. As a result, clients can expect clear, accurate drawings that support a smooth and efficient permitting and construction process.
I established DBA Design & Drafting with a commitment to delivering a higher standard of design and service. I take pride in clear communication, attention to detail, and creating designs that are both functional and visually refined, ensuring a positive and professional experience from concept to completion.
