Our History

A Heritage of Excellence

The Beginning of a Legacy

Since Ed “E.T.” Thevenot began the company, Perka Hybrid Buildings has always made the client #1. We began our journey of quality service specializing in manufacturing, marketing and distributing wood-steel hybrid buildings in 1981. The structures, composed of steel frames, wood secondaries and metal sheeting, are pre-engineered and individually-designed according to exacting specifications.

Across the country, you’ll see Perka Hybrid Buildings in use for agricultural, industrial, commercial, community and residential purposes!

The manufacturing branch of our enterprise, Interlock Steel Structures USA Inc., fabricates a wide range of structural steel components, actively marketing through a network of dealers and distributors throughout North America and across the globe.

The Reputation for Excellence Grows

As Perka’s reputation grew across the continent and beyond, E.T. developed a line of reflective insulation materials still offered today as the Perka Insulation Board. Our products expanded further to ornamental steel, including railings, fences and gates.

Excellence, Expanded

In the early 2000s, the leadership of Perka Hybrid Buildings transitioned to E.T.’s son Martial Thevenot, who was later joined by his son Guy. Guy was instrumental in the development of a new branch of the business, Veritas Systems Construction, in 2011. The growth of our enterprise soon led to another family member joining the enterprise, and E.T’s granddaughter Sponge was added to the team.

In 2019, we added BARNFixer.com to expand our services offered to neighbors, friends and family requiring a repair, upgrade or expansion to an existing barn or building.

Continuing the Legacy

Throughout the life of our company, Perka Hybrid Buildings has been guided by the strong and determined leadership E.T. consistently demonstrated, and we continue to embrace his core values. E.T. celebrated integrity, commitment, quality, innovation and good stewardship. Just like E.T., our team at Perka Hybrid Buildings always believes that the client is #1.

Our Why

We rise and shine every day to seek out stress-free solutions for buildings so that we are all healthier, safer, more fulfilled, more secure, and happier givers.

Our Vision

Being students of many incredibly wise and successful model entrepreneurs, we aspire to always live up to the highest standards of integrity and service that we can, both individually and collectively.

Hill, Sinek, Robbins, Carnegie, Ford, Edison, Winfrey, Gates, Nightingale, Dyer, Chopra, Walsh, Disney, Stone, Hansen, Ziglar, Maxwell, Vaynerchuk, Redfield, Branson, Tolle, Proctor, Job, Buffet, Blood, Hawkins, Buddha, Musk, Canfield, Dalai Lama, Tesla, Tracy, Waitley, Buscaglia, Nhat Hanh, Blanchard and Jesus Christ, are just some of the names of the major influences that have had a role in the formulation of many on our team making up who we are as we continue to evolve.

To help us stay the course on this infinite journey and maintain a certain strength of perseverance, this website represents the bringing together of all of our business parts — Hybrid Buildings Solutions, Interlock Steel Manufacturing, Veritas System Construction, Super Insulation Board Solutions, barn repair, fences, railings, gates, decorative and security enclosures, metal art and yard beautification, and more to come.

Through the introduction of a coat of arms — The T-SHIELD — we pay homage to a long family history through many generations and tribal lineages that always endeavored to stand for being worthy of blessings received in humbled mercy. The “T” represents our founder’s family surname, Thevenot, as well as our commitment to stand arm-in-arm for the 4 T’s — truth, teamwork, trust and togetherness. It has been passed down through the generations, that these four main virtues will make us stronger, more agile, more resilient, more effective and less stressed! All this lends to an existence that is generally healthier, happier and more prosperous.

This T-SHIELD symbol, worn with a certain faith, will represent a force of protection and empowerment to enable us to forge ahead in sincere, selfless service to and for each other and everyone we meet.

Our Mission

Our day-to-day mission is to continue to stand out and be a leader-innovator in the steel-wood hybrid building industry, as well as in seeking out the most serving and simple sustainable solutions. This all starts with a focus on supplying products that are consistently strong, affordable, flexible, easy and resilient.

We achieve this by providing personalized client service, quick turn-around of information, design options, solution ideas, drawings and products of value. We maintain the highest standard of integrity in all our work while getting it all to our client at value-added prices.

By having all the mates and various skillsets working together as Team Perka, committed to doing things right, we endeavor in every moment to always merit the respect and earn the trust, friendship and loyalty of each client. We aspire to co-create, with each other, relationships based on respect, confidence, trust and moral responsibility, and where we all can succeed, feel fulfilled and be happy.

As Team Perka, we are dedicated to each client’s satisfaction through this trust and confidence in knowing that the materials and services for each project will be provided with the utmost of care, pride, workmanship and attention to quality.

Our Founder

Born in 1936 to an extremely hard-working dad and a shrewd but very loving mom, Ed Thevenot (E.T.) quickly knew he wanted to be a business man. Since his first sale of two packets of garden seeds at 12 years old, he specialized in sales and marketing. Over the years, he successfully promoted and sold everything from pots and pans, to computer courses, to recreational vehicles and building materials.

With his entrepreneurial fire burning, he jumped into the building industry in 1971, promoting and marketing pre-engineered Quonsets in the province of Quebec. Within a few short years, his dynamic personality, hard-driving work ethic, and unswerving dedication to his men landed him vice president of marketing for the head office of the Miracle Span group of companies. In 1980, he decided he was a better entrepreneur than employee, and created his own line of buildings — the cutting edge, hybrid design of Perka (wood and steel) buildings.

In 1995, he was frustrated with inadequate insulating materials as he tried to construct more energy efficient buildings. So, in response, E.T. created P2000 Insulation Systems and P2000TM insulation for Perka buildings. He went through several manufacturers looking for the right formula of high-quality product, dedicated service and a creative, entrepreneurial spirit to match his own.

E.T. was the brainchild behind the marketing engines that have maintained steady sales, in both buildings and insulation, for almost 40 years. His experience, fearless risk-taking, and work habits helped him foresee market trends that enabled his team to respond quickly with assurance and success. Unfortunately, E.T. is no longer with us, but he has left behind an experienced, skilled, highly energized and passionately dedicated team.

We'd love to help you complete your next project.
