Age Value and the 50-year rule

The latest issue of Forum Journal (from the National Trust for Historic Preservation – you can join here.) has an article questioning the 50-year rule. The National Register of Historic Places was created in 1966 and shortly thereafter the Park Service promulgated policies for listing properties on the National Register. Eight categories of properties have to jump some more hurdles to become landmarks: birthplaces, gravesites, cemeteries, memorials, relocated buildings, reconstructed buildings, houses of worship, and buildings less than 50 years old.

Now, first it should be noted that I can name properties in each of those categories that ARE on the National Register of Historic Places, but they had to prove extra significance.

The article, by Elaine Stiles, notes that the 50-year rule actually dates from the Historic Sites Act of 1935 as a guideline for the Park Service and its publicly owned sites. They originally rejected all sites before 1870, and then revised it in 1952 to “50 years”. Stiles notes there is no evidence as to why 50 years was chosen, but it is a problem, since most buildings are threatened with demolition or remodeling within 25 or 30 years of their initial construction. Heck, the Rookery by Burnham & Root (1886) was totally remodeled on the inside only 19 years later, in 1905.

by Frank Lloyd Wright

it was remodeled again 25 years later by Wright’s student William Drummond, with elevator doors by Annette Cremin Byrne. The point is, the cycle of building remodeling is a lot quicker than 50 years. EVEN some of the most famous battles in preservation history happened to buildings about my age. Penn Station, the epochal demolition in the early 1960s that helped spur New York City’s Landmarks Ordinance, was only 52 when the wrecking ball hit.

Chicago’s Robie House was only 47 years old when the Chicago Theological Seminary proposed demolishing it for a dormitory.

Now, the idea of letting some time pass before you decide whether something is worth preserving has merit. A century ago Alois Reigl defined several reasons for saving historic sites, including “age value,” “historical value,” “art value,” and “use-value”. For Reigl, “age-value” and “historical value” were about the past, while “art value” and “use-value” were about the present and future.

Personally I think our preservation/conservation field today is all about “use-value,” but our criteria still put a lot of weight on the artistic and historical merits of properties we want to conserve. Reigl defined “age-value” with reference to evidence of decay or aging, which would inspire nostalgia. Like historical value, it resided in the past. This is arguably a Western value, deriving from the aesthetics of decay so prevalent in writers like John Ruskin, and I agree that there is something to the sense of age that certain historic sites can evoke.

I used to always relate a story I heard about Frank Lloyd Wright’s 1894 Winslow House in River Forest. I heard that a woman lived across the street from the house for decades and she told an interviewer that she had looked at that house every day for 50 years and never got tired of looking at it.

I don’t know the validity of the story, but it seemed an excellent definition of a landmark. Although, in reality she was referring not to age value but art value, one of Riegl’s present values. If it looks good for a half century, odds are its “beauty” is not a passing fashion.

One of the examples in Stiles’ article was Chicago’s Inland Steel building, built in 1957, landmarked by the city in 1998 and listed on the National Register in 2009. Actually, the story is even more amazing than that.

Inland Steel was considered a landmark before it was even completed. It was included in the first lists of Chicago landmarks, and there is actually a city landmark plaque from 1960 (the paint probably wasn’t even dry yet) still visible on its exterior.

Inland Steel was considered landmarkable in 1960 and it still is today – Frank Gehry even became a part owner he thought it was so cool.

But back to Stiles’ argument against the 50-year rule, which notes several places, including Chicago, that have no age limit on their landmarks. Indeed, in Chicago we have a National Historic Landmark that made the grade at the youthful age of 25. Then again, it was the site of the first self-sustained nuclear reaction, which is a scientific achievement we all agree was more than a little significant for subsequent earth history.

We also designated numerous Mies van der Rohe buildings before they hit 50 years old, because, well, we knew he would remain one of the most significant architects of the 20th century.

It isn’t simply the date of construction that is important, either. in 1990 the City of Chicago landmarked – to great public acclaim – the Chess Records Studio at 2120 South Michigan Avenue, the only Chicago Landmark to have a Rolling Stones song named after it. The building dates from 1911, but it achieved its significance – as Chess Records – from 1957 to 1967.

But the real problem is not exceptional sites but typical sites. Stiles notes that only 3 percent or less of sites on the National Register are less than 50 years old, and that most places that matter to people today will be less than 50 years old and will NOT meet the standard of “exceptionally important.”

When we were landmarking properties in the 1970s and 1980s, we were coming up against 1930, which represented the beginning of a generation-long hiatus in the construction industry – very little was built between 1930 and 1946. But once we hit the 1990s, postwar buildings started to become eligible even under the 50-year rule, and today a building from 1960 is eligible. But that also means many 1960s and 70s resources are being threatened, if they have not already been lost.

At SAIC’s Historic Preservation Program, we have been dealing with this issue for years. Anne Sullivan started a course in Preserving the Recent Past in the 1990s, and for the last four years together with Landmarks Illinois, (and thanks to Jim Peters) our students in the Preservation Planning Studio class have been surveying the postwar buildings of suburban Cook County, and finding a host of swinging 60s gems, almost none of which have any form of protection.

Age value is important, but it is only one of the criteria used to determining what to conserve and retool for the future.

I suppose I am sensitive to the 50-year rule since I became eligible myself this summer. My half century birthday occurred in two buildings, this one I woke up in in Germany, a Jugendstil treasure from 1907

And this postwar Buitenveldert townhouse in Amsterdam that I went to sleep in. Heck, it was probably younger than me.

I found them both to have art value, age value, and historical value. And they both obviously had “use-value” because families live in them. And now I am commemorating them.
