Litebox Inc.

About us

Litebox is a Winnipeg based, employee-owned firm; a pioneering force in the realm of high-performance building envelope engineering. Founded by Grant Walkin, a visionary for a better tomorrow and industry expert. Our company is driven by a passion to support the future of architecture and the construction landscape with innovative designs that seamlessly merge form, function, and sustainability.

Litebox Inc. (Litebox) is a boutique building envelope and structural glass engineering firm who is passionate towards reshaping the built environment with healthy, resilient, durable, low energy, low impact, high performance buildings. Our services include building envelope design, building envelope commissioning, structural glass engineering, passive house consulting, deep energy retrofit consulting, thermal modeling, and forensic investigations. Our clients are architects, builders, and owners who share our values of innovation and sustainability and simply want to build better; projects range from single family to commercial to institutional buildings, for both new and existing builds.
Our Vision
At Litebox, we envision a world where high performance low energy buildings harmoniously coexist with the environment and their communities. Our ambition is to be at the forefront of the movement, bridging the gap between cutting-edge engineering solutions and carbon-conscious practices to create structures that are long lasting, resilient, durable, safe, comfortable, and environmentally responsible for individuals of all socioeconomic backgrounds.
Who We Are
At Litebox, we are committed to reshaping the future of building envelope engineering, design and construction, through innovative solutions and parametric modelling. The building enclosure permanently forms the most important system of a building, affecting its durability, energy performance, and occupant comfort. We blend cutting-edge engineering expertise with a deep understanding of sustainability principles to create optimized structures that are not only aesthetically pleasing, but also endure the test of time, while providing the upmost comfort.
The spelling of lite is derived from a glass lite, a single piece of glass, also referred to as a glass pane. It signifies the literal structural glass and building envelope services we provide, and figuratively stand for our energy efficient and lightweight designs. The box represents the simple shape of a building and the building enclosure we pride ourselves in designing with the “(building) envelope first” approach methodology. We like to think a “Litebox” is a spark of thought that is idea driven, similar to a lightbulb illuminating, to encourage thinking outside of the box.
Our Mission
Our mission is to be more than engineers; we are partners in our clients' quests to build better. We are experts to fundamentally improve the building and limit owner risks, striving to be more than just another consultant on the project list. Throughout every step of the project, we strive for the value of service to overshadow the cost of service. We are dedicated to delivering engineering excellence that exceeds technical standards and ignites imaginations. With a focus on green practices and sustainable principles, we are committed to minimizing our ecological footprint while maximizing practicality and cost efficiency of every project.
