Preserving Resources from the Recent Past, by Jeanne Lambin.  Published by the National Trust for Historic Preservation. 2007. (Out of Print)

Description:  Love them or hate them, there's no question that "modern" buildings of the postwar era (1940s to '60s) transformed cities, towns, suburbs, and landscapes throughout the country. Now preservationists need to take a serious look at these resources -- too new to be considered "historic" by many, but old enough to be in danger of alteration and replacement -- to consider which ones merit protection. Preserving Resources from the Recent Past, a new Preservation Book by Jeanne Lambin, looks at the historic context of the postwar building boom, the special challenges of preserving this legacy, and some case studies of community successes. The 28-page book also features an illustrated guide to building types and styles.

Mid-Twentieth Century Preservation. Illinois State Historic Preservation Office, Illinois Dept. of Natural Resources.

Main Street changed dramatically in the mid-twentieth century as new buildings were constructed and older storefronts were remodeled to make them modern looking. In small towns and mid-sized cities across America, the first architectural expression of Modernism was often the bank, specialty shop, store, cinema, or pharmacy. Unfortunately, many of these “recent-past” resources are swiftly disappearing from our built environment, often before their importance is recognized. The preservation of smaller-scale, post-World-War II commercial downtown buildings is complicated by their both their familiarity and their incongruity. These historic resources from the 1940’s, 50’s and 60’s often go unrecognized by preservation efforts because they are just too “new” for many to recognize their cultural and historic significance. Furthermore, the sleek lines and smooth facades of post-war construction often contrasts sharply with the more traditional downtown buildings that preservationists warmly embrace. To further complicate the issue, new materials, technologies, and design assemblies of the mid-century often require new approaches to building repair and conservation. Yet these buildings reflect important developments in style, design, economics, and technology that resonated across a newly consumer-oriented America.

The Illinois State Historic Preservation Office (IL SHPO) has had a long-term enthusiasm for the preservation of resources from our more recent past. This site will make available online to the public technical, preservation and historical information created by IL SHPO staff.

New Canaan, Conn. Modern Homes Survey (unknown link)

The Survey of New Canaan homes was prompted by the demolition of the Paul Rudolph home in Westport CT in 2007. A part of the Judge’s decision to allow demolition was the “lack of criteria for significance”. That same year we were opening the Philip Johnson Glass House to the public with great fanfare and interest. How could our Modern assets garner such interest but simultaneously be threatened because of a lack of terminology, criteria or documentation.

As Modernism is our newest entrant into the continuum of architectural movements requiring historic preservation, this teardown was a call to action. The National Trust for Historic Preservation, through the Glass House, partnered with the New Canaan Historical Society to leverage an earlier study done by DoCoMoMo’s Northeast chapter to expand/ enhance, publish and put on-line the survey of the remaining 91 modern homes in New Canaan. Across this site you will see our goals, examples and content to create better tools, common vernacular and greater awareness. Our hope is that other communities embarking on a modern survey will connect to these tools and expand this site to showcase the homes and architects of this newest era of preservation.

Split Visions Remodeling Planbook (unknown link)

Description: A consortium of 15 metropolitan communities partnered to produce an idea book for remodeling, improving and updating split-style homes. Owners of split homes were invited to offer their comments and ideas about what they liked, disliked and what they would like to change about their homes. Homeowner responses were compiled and the planbook derived from their desires and suggestions.
