Found this Construction article on Modular Construction. I found it interesting because it discusses the past and present.

While modular building dates back at least a century, it gained national attention as troops returned home after World War II, when it became the preferred building method for housing in rural and suburban settings across the United States.

The 1960s and 1970s gave rise to more complicated designs as consumer demands became more sophisticated, and in the 1980s, even more intricate modular homes began to take shape across the Northeast, in New Jersey, Pennsylvania and, to a lesser degree, New York.

“The New Jersey suburbs are full of beautiful, custom-designed houses that were executed in modular factories,” Mr. O’Hara said.

Slowly, modular seeped into the commercial industry, becoming popular for building low- to mid-rise structures—affordable housing, hospitals and other medical facilities, schools and office complexes—with companies like Capsys, Deluxe Building Systems and NRB among those paving the way in the Northeast.

Note: in the above the O'Hara quoted is not me. My name is Ohara, but people stick an apostrophe in my name all the time. Makes it a really pain for medical records reconciliation.

The construction industry can be slow to change, and a recent project may help to change the perception.

Proponents of the method have treated modular design as gospel for years, and real estate industry professionals (even those not directly involved in modular building) agree that the cost and time savings afforded in smaller-scale projects translates into larger, taller buildings.

“It’s one of the best-kept secrets in the real estate industry, but I think that this building will change that,” said Amy Marks, owner and president of XSite Modular, the modular consultant on the Atlantic Yards project. “If you’re building a building today and not considering some sort of modular or prefab, you’re missing out on a tremendous value.”

Modular is not anything new, but not used by all.

But most agree that incorporating at least certain elements of modular design is beneficial, with firms across the city opening up to the idea.
