About us
GIANT Architecture is a Colorado-based residential design studio focused on creating modern, intentional homes through a thoughtful and collaborative process. We specialize in custom homes, renovations, and additions—tailored to the diverse lifestyles and landscapes of Colorado, from the Front Range to the mountain communities.
Our approach blends contemporary aesthetics with technical precision, offering a full range of services including design development, 3D visualization, and permitting support. We use industry-leading tools like Revit, Photoshop, and Enscape to deliver highly realistic renderings that help clients visualize every detail of their project early in the process.
At GIANT, we prioritize sustainability and long-term livability—integrating energy-conscious strategies, material efficiency, and site-responsive design from day one. With extensive experience navigating Colorado’s permitting and zoning requirements, we guide each project from concept to approval with clarity and confidence. Our goal is simple: to design homes that feel as good as they look, and work as beautifully as they live.
Behind GIANT
With over 7 years of experience in residential architecture, I’ve designed dozens of homes across the U.S. and Brazil. With my diverse academic background, I hold an architecture & urban planning degree from a top-ranked architecture school in Brazil along with a year of full scholarship at CU Boulder’s Environmental Design program.
My work is grounded in a passion for modern design and a strong commitment to sustainability. I strive to create spaces that not only reflect each client’s vision, but also minimize environmental impact through smart and responsible solutions. I believe every project is a true collaboration—where your goals and lifestyle are shaped by thoughtful planning, creativity, and technical expertise to bring your dream home to life beautifully, functionally, and sustainably.
