FIFTEEN is a design-focused architecture practice driven by the desire to affect positive change. We are change makers, connectors, and bold thinkers committed to amplifying the role that architects and designers have in shaping our world. Inspired by the power of great design, we see ourselves as a catalyst for innovation and aim to redefine the dynamic between clients, communities, and designers. Embracing an ethos of authentic collaboration and innovative disruption, we are a forward-thinking organization where collaborative people, transformative ideas, transparency, and technology drive creative design solutions.

FIFTEEN is rooted in the belief that the best results are obtained through interdisciplinary collaboration and multiple perspectives. Our unique structure of a women-led practice with a network of collaborators has served as a springboard upon which we have shaped our policies and processes. We approach each project with empathy and deep understanding of the needs and aspirations of our clients. By integrating their values, hopes, and dreams into the design process, we ensure that every project becomes an authentic reflection of their vision.
