Life & Work with Tim Siahatgar of Irvine CA

Today we’d like to introduce you to Tim Siahatgar.

Hi Tim, we’d love for you to start by introducing yourself.
My journey began with a strong academic and professional foundation in architectural engineering, where I developed both the technical expertise and creative vision necessary to rethink conventional construction methods. From the beginning of my career, I have been driven by problem-solving, sustainability, and innovation—particularly in addressing the inefficiencies, waste, and limitations of traditional building systems.
I have always believed that architecture must serve both human needs and environmental responsibility. Visionary thinkers such as Buckminster Fuller profoundly influenced my perspective, reinforcing my belief that structure, material efficiency, and adaptability are essential to the future of building design.
Early in my professional practice, I became deeply focused on one fundamental issue in construction: connections. Whether in wood framing joined by nails and adhesives or steel structures connected by welding and bolts, connectors ultimately define a building’s strength and longevity. Through years of research, I recognized that aluminum extrusions offer remarkable advantages—lightweight strength, durability, recyclability, and precision—but for over a century, the industry struggled to solve the problem of effectively connecting hollow aluminum profiles in load-bearing structures.
After extensive research, experimentation, and testing, I developed an improved interlocking clamping and bolting system for modular aluminum framing. This breakthrough allowed aluminum extrusions to be used efficiently for real buildings—not just interiors or experimental structures—while meeting stringent seismic, wind, and code requirements.
Today, this work has evolved into MHS Building Systems, a certified and award-winning structural aluminum framing technology used in hundreds of built projects. As an architectural engineer, designer, and inventor, I take great pride in contributing a system that enables recyclable, relocatable, resilient, and sustainable buildings, while pushing the construction industry toward a more responsible future.

We all face challenges, but looking back would you describe it as a relatively smooth road?
It has definitely not been a smooth road. The development of MHS has occurred in clearly defined phases, with Phase One spanning nearly ten years—from 2013 to 2023.
This first phase focused almost entirely on research and development. It involved building domain expertise, developing proprietary knowledge systems, securing trademarks and patents, conducting extensive structural material testing, and achieving compliance with California and Los Angeles building codes. Navigating approvals, testing protocols, and regulatory requirements—especially for a new construction methodology—was one of the greatest challenges.
Despite these hurdles, Phase One culminated in the successful construction of over 400 small residential and commercial structures across Southern California, validating the system in real-world conditions. The challenges were substantial, but they were essential in refining the technology and establishing a strong foundation for future growth.

Appreciate you sharing that. What else should we know about what you do?
As an architectural engineer with a strong design background, I have always been motivated by a clear goal: to replace traditional lumber framing for light buildings, particularly in Southern California. The objective was to create a system that reduces deforestation, improves seismic performance, and eliminates many of the fire and durability issues associated with wood construction.
This mission led me to develop a modern structural system that blends Modernist architectural principles with advanced eco-friendly technology. MHS buildings are constructed using high-precision, prefabricated aluminum components that emphasize material honesty, efficiency, and adaptability.
The framing system relies almost entirely on mechanical connections, significantly reducing dependence on nails, glues, and chemical adhesives. Recycled materials are incorporated wherever possible, enhancing both sustainability and long-term value.
MHS prefab homes and structures give clients the freedom to choose finishes, layouts, and materials without being constrained by traditional framing limitations—offering flexibility, innovation, and architectural clarity.

In terms of your work and the industry, what are some of the changes you are expecting to see over the next five to ten years?
“The construction industry is undergoing a major transformation, and modular, prefabricated, and sustainable building systems will define the next decade.
At the center of this shift is the MHS Structural Aluminum Framing Design, a system that challenges the inefficiencies of conventional construction by offering:
• Reduced construction waste through recyclable materials
• Enhanced energy efficiency for net-zero buildings
• Superior seismic and structural resilience
• Faster construction timelines and cost predictability
• Scalable modular solutions for residential and commercial use
MHS has already demonstrated its value through hundreds of completed structures in Southern California, particularly in urban environments where speed, sustainability, and adaptability are critical.
Looking ahead, my focus is on global expansion, including:
• Advanced seismic testing at the world’s largest outdoor shake table at UC San Diego
• Development of large-scale net-zero communities
• Urban infrastructure solutions that are resilient, adaptable, and environmentally responsible

A Sustainable Future – The Ultimate Goal
My long-term vision extends beyond individual buildings. I envision a future where sustainable modular construction becomes the global standard, replacing wasteful and environmentally damaging building practices.
My ultimate goal is to establish a global network of prefabricated modular communities that:
• Help address housing shortages
• Increase access to sustainable living
• Enhance resilience against climate change and natural disasters
For me, architecture is not just about form or structure—it is a tool for solving global challenges. Through MHS Building Systems, I am committed to shaping a future where innovation, sustainability, and human well-being are inseparable.
