Giovanna Antonelli
GIANT Architecture is led by Giovanna Antonelli, a residential designer with experience in both Brazil and the United States. Her work focuses on thoughtful, functional, and site-specific design for custom homes, remodels, additions, and interior renovations.
As a solo designer, Giovanna works directly with each client and contractor, creating a more personal and efficient design process from early concepts through construction documents.
With a strong understanding of residential design, permitting coordination, and construction documentation, Giovanna helps homeowners move from initial ideas to clear, buildable design solutions.
What clients say
“Giovanna was wonderful to work with. She listened carefully to what we wanted, helped us understand the design possibilities, and created a thoughtful plan that made the process feel clear and manageable.”
Thoughtful, practical, and personal
We believe good residential design should feel personal, practical, and connected to the way each client actually lives. Every project begins with listening, understanding the site, and developing a clear design direction before moving into drawings, coordination, and construction documents.
