Opinion: The prefab homes of the past are now the future

Modular housing is now being used in B.C. for workforce and homeless housing projects, but why not much-needed regular homes?

Long before online ordering at Amazon.ca, the Sears print catalogue was the major shopping source for Canadian families, especially those in rural areas lacking any nearby retail locations.  They bought household tools and appliances through mail order as well as the same item of kids’ clothing in multiple sizes, with an easy return policy for items that didn’t fit.

But a lesser known item at Sears was the pre-fabricated single-family home, mass-produced in a U.S. manufacturing facility by Sears, Roebuck and Co. More than 100,000 of these homes were sold between 1908 to 1940, shipped in “kits” throughout the U.S. and Canada for onsite assembly. Priced at less than $2,500, kits included some 30,000 pieces, such as lumber, nails, paint and shingles, plus an instruction book, similar to a child’s Lego set. Owners could hire someone or choose to build the homes themselves, often convincing friends and family to provide sweat equity.

That early innovation is now back in style. In a bid to improve current housing affordability challenges and combat rising land and construction costs, many cities are returning to that prefabricated (prefab) or modular construction. Prefab is now featured in everything from single-family homes and seniors’ complexes to six-storey hotels and 25-storey apartment buildings. These homes are currently being designed for B.C.’s Kitimat LNG employees.

Stack Modular, one of our Urban Development Institute members, specializes in this cost-effective construction method for multi-family housing, hotels, and student residences. Their operations manager Matt Hallaran recently described the benefits at our November educational seminar, attended by almost 200 interested builders.

The major advantage is manufacturers can build within a large indoor, climate-controlled factory, at a much faster rate, while demolition, excavation and foundations are concurrently completed on the actual site. Depending on the project complexity, shipping destination and other factors, a builder can save up to 50 per cent on construction time and about 20 per cent on the cost of traditional construction, due to a shorter financing period.  A six-storey hotel can be built on the factory floor in three months and assembled on site in about 20 days, allowing three to four months of additional finishing work for mechanical, electrical, and plumbing. Compare that to an approximate 24-month conventional construction timeframe for a similar project. Construction disruption to the surrounding neighborhood is also significantly reduced. 

Contrary to some assumptions, a modular building is not a cookie-cutter, basic box.  Pre-fab homes are incorporating modern and pleasing architectural elements plus customized, eco-friendly and smart home technology by design. People won’t even know they’re modular.

Some B.C. communities have already welcomed modular housing, approving projects for the homeless in as little as six weeks. But Canada has been slow to adopt this construction method for urban developments, unlike our European or American counterparts. One of the world’s larger hotel chains, the Marriott, recently opened a modular hotel in California with 97 rooms, called the Folsom Fairfield Inn & Suites, with plans for more.

A 32-storey skyscraper was recently completed in New York with similar high-rise modular buildings to follow. Even the Swedish company, IKEA, is selling pre-fabricated homes called BoKlok. In the last 20 years, IKEA has soldmore than 11,000 modern, prefab homes to European clients. They cost 40 per cent less than their traditionally built counterparts and are ready in eight to 12 months.

The Financial Times reports that prefabricated homes comprised 16 per cent of Japan’s housing built in 2015. The Malaysian government went further, dictating 70 per cent of all construction should be prefabricated.

For British Columbia, where many are struggling to afford a good home in many communities, these prefabricated homes represent a smart living solution. With straightforward designs and high-volume manufacturing, they can help lower costs while maintaining high-quality standards.
