Hi, I'm Elham Khataei, a design-focused architect-in-training with a passion for translating complex ideas into tactile, buildable environments. I earned an HBA in Architectural Studies at the University of Toronto (Graduated with high distinction) and am advancing toward a Master of Architecture. My work blends technology, landscape, and urbanism, with a hands-on approach to robotic fabrication, digital modeling, and site-responsive design.
Through teaching, research, and on-site fabrication projects, I explore how architectural systems can respond to climate, program, and community. I'm fluent in Persian and English, curious by nature, and always looking for collaborative opportunities to push the boundaries of design and fabrication.…Hi, I'm Elham Khataei, a design-focused architect-in-training with a passion for translating complex ideas into tactile, buildable environments.
