Built Prefab is completely devoted to building new modern healthy modular prefab homes utilizing the most exciting and effective building science available on the planet including 3D design and modern modular production technology to deliver exceptional high value to all home buyers across Oregon, British Columbia, Washington and Alberta.

Built Prefab is formed by a team of experienced entrepreneurs in the modular prefab industry. A shining and bright example is Built Prefab’s excusive proprietary software including Build and Price tool which clients can find at builtprefab.com. The Build and Price online tool is a completely automated platform which is intended to design and price a client’s new modular prefab home.

“Our online Build and Price platform is our unique method of selling homes. It’s a place where customers can choose a model, select options and price their own home without ever needing to talk to a salesperson. It’s a complete 180 from the massively hands-on traditional approach of designing and building new homes” says Ian Garrity, President.

Since company's inception, they have introduced to homebuyers 11 modern modular prefab home models. New prefab modular homes range from 768 square feet to 3,280 square feet.

The company offers a variety of contemporary, high quality finishes. There are also superior building performance options available.

Additionally, the company has developed a modern standardized modular design system that includes a wide range of beautiful contemporary finishes, kitchens, baths and other interior options.

“Starting from day one we are a legitimate tech company, that just happens to be in the business of building awesome homes. Our goal is to create a new version of the custom homebuying experience where designing and buying a home becomes more like designing and buying a new car. Picture, fully automated online sales combined with factory production” says James Rosowsky CEO.

On March 3, 2025, Built Prefab, a company formed by James Rosowsky and known as “a leader in modern modular housing,” announced the acquisition of Lake Country Modular, “a respected provider of attainable, high-quality manufactured, modular, multi-family and First Nations housing.”

“This strategic acquisition significantly enhances Built Prefab’s product offerings, enabling it to deliver more move-in-ready housing options and innovative solutions to meet the growing demand across Western Canada,” said a release by Built Prefab Corporation.

A 1994 graduate of the Kamsack Comprehensive Institute, James Rosowsky, the CEO of Built Prefab, is one of four children born to Connie and the late Orest Rosowsky of Kamsack. His mother, a retired principal of the KCI, currently lives in Yorkton, while his sister conducts a legal practice in Kamsack.

Before moving to Kelowna, B.C., where he lives with his wife Karley Scott Rosowsky and two children, aged 17 and 19 years, James had attended the University of Saskatchewan in Saskatoon where he received his bachelor’s and a law degree while keeping an interest in music by performing in a number of bands, including Junto and The Pinch.

James has “a proven track record of assembling teams and establishing processes that foster growth and innovation,” the release said. “In his earlier career, James first pursued his passion as a full-time musician before transitioning to become a business lawyer.

“James’s diverse interests have allowed him to develop valuable skills in web development, online systems, building design, and construction management.

“With a strong entrepreneurial spirit, James ventured into the prefab industry in 2013 with Karoleena Homes. As CEO, he adeptly expanded the company until its acquisition by Horizon North Manufacturing in 2016.

“In 2019, James founded Built Prefab, where he remains committed to building a team and cultivating a company that can effectively achieve its mission. His multifaceted background and leadership qualities make James a versatile and dynamic force in the industry.

“We're thrilled about this opportunity to expand our range of products and contribute positively to addressing B.C.'s housing crisis,” Rosowsky said. “The integration of Lake Country Modular into our group will streamline project timelines, enhance efficiency, and reinforce our shared commitment to sustainable, high-quality construction.”
