In*Situ Architecture

Company Profile

In*Situ Architecture, co-founded by William C. Helm II, AIA, and Edgar Lopez, AIA, is a distinguished architectural firm with over 48 years of combined experience. Since our establishment a decade ago, we have consistently delivered award-winning projects that stand as a testament to our unwavering commitment to beauty, sustainability, and community-centered design. Our portfolio is a testament to our diverse body of work, showcasing our dedication to creating spaces that uplift individuals and entire communities. Notably, our recent conceptual design for the Advanced Manufacturing and Design Center to be located on the grounds of the El Paso International Airport secured a substantial $40 million federal grant, solidifying our role in advancing industrial growth. In*Situ is one of the pioneers in the architectural realm, continuously breaking new ground with a profound emphasis on innovative tilt-up construction. Our portfolio showcases our unwavering commitment to pushing the boundaries of architectural potential, where we transform utilitarian methods into exceptional, almost artistic creations utilizing architectural tilt walls. Furthermore, our expertise in historic preservation and rehabilitation reflects our deep respect for the past while seamlessly coexisting with our drive to build for the future. As architects defined by boundless curiosity, we remain at the forefront of design exploration, continuously crafting spaces that inspire and endure.
