Milwaukee was long known as the Cream City, when its buildings were adorned
with a handsome local variety of pale brick that gave the city a distinctive
light appearance. But it may be time to call it the City of Moving Roofs:
a gossamer design by Santiago Calatrava will move with the sun to shade
the atrium of the Milwaukee Art Museum addition (and is so delicate and
complicated that there is speculation whether it can actually work); a movable
roof for Miller Park, the Brewers' new baseball stadium completed in April,
is as beefy as a bratwurst and bigger than an airplane hangar.
Among seven movable North American stadium roofs, Miller Park is the first
that's fan-shaped and opens radially, making it the only one of its kind
on the continent. It may also be the least obtrusive of the breed, even
though when open it's the tallest, at about 330 feet. The Brewers set it
in motion at the end of every game, accompanied by music from the sound
track for 2001. Fans linger to watch the ceremony, applauding at
the end. This is not just local boosterism; there is something beautiful--even
mesmerizing--about flve immense roof panels gliding effortlessly overhead
to a Strauss waltz.
It's not stifiing like Seattle's Safeco fleld, whose canopy is an instrument
of darkness. In Milwaukee, natural light fllters in from three directions
even with the roof closed. Beyond the outfield, large translucent wall
panels open and close with the roof. Under the roof arches along the baselines
are nicely detailed window walls that are grand in scale--530 feet long
and about 90 feet high at their apex. Their appearance recalls the end of
a glazed train shed in a nineteenth-century railroad station--the image
designer Dan Meis of NBBJ Los Angeles used when presenting his proposal
to the clients. (Other members of the design team were HKS of Dallas and
locally based Eppstein Uhen.)
Miller Park's great design coup is its manipulation of natural light and
the impressive architectural elements that transmit it; of the eight roofed
stadiums I've seen in North America and Japan, this is easily the finest
in that regard. The structure is also praiseworthy for its deft handling
of circulation. There are no pedestrian bottlenecks (unlike the recent Pac
Bell Park in San Francisco); it is easy to go between levels via escalator,
elevator, or stairs; and the ramps, which can be awkward in other stadiums,
are discreet and unobtrusive.

Park are more than 40 feet farther from the batter.
The Brewers' ballpark creates what Reyner Banham would have called a well-tempered
environment. Milwaukee's early and late-season climate can be frigid, but
the roof and the fully glazed walls seal the building so that a massive
air-handling system can warm the interior as much as 30 degrees above the
outside temperature. The Cream City is major-league baseball's smallest
market, so the Brewers can't afford to lose patrons to cold weather. Most
fans will also like Miller Park for another reason--the shorter outfield
fences, as well as warmer temperatures, permit more home runs than the old
stadium did. At deadline time, the Brewers were hitting 90 percent more
home runs per game at home than they did last year.
These are Miller Park's greatest strengths--and they are significant.
But by their very nature, large American stadiums are imperfect. The design
inevitably involves geometric trade-offs, fast schedules, budgets that don't
permit refined detailing and fine flnishes, and a dearth
of skilled clients.
Miller Park, unlike most of the dozen other post-1989 ballparks, occupies
a suburban environment of parking lots and freeways. This dates back to
the early 1950s, when County Stadium--Miller Park's underrated predecessor--was
built near an abandoned quarry. The resulting fan culture became one of
sausage grilling at tailgate parties rather than urban synergy. There was
political support, led by Mayor John O. Norquist, for locating County Stadium's
replacement downtown, but inertia, along with the Brewers' desire to capture
maximum parking revenues and stadium spending, led to it being built a few
hundred feet away. This may prove to be a poor long-term decision for the
Brewers as well as for the city. Attendance data suggest that ballparks
in urban settings draw more fans than those in suburbia.
The Brewers wanted a new suburban ballpark, but they wanted it to look like
an old urban one. About ten years ago, before the final design team
became involved, they released drawings of an oversize, Ebbets fleld--inspired
exterior, which was later incongruously combined with an even larger high-tech
retractable roof. Ever since, the Miller Park project has embodied a basic
design confiict between rationality and subjective nostalgia.
The roof and the basic building form that grows from its geometry are symmetrical,
but the fleld shape and seating patterns inside are not. This tension
grows out of a questionable impulse to emulate vanished 90-year-old ballparks
and manufacture character and uniqueness out of whole cloth. But old parks
such as Ebbets fleld and the Polo Grounds, and the better retro ones such
as Pac Bell Park and Baltimore's Camden Yards, earned their identities legitimately
through adaptation to site constraints and opportunities, not through self-conscious
and arbitrary asymmetry. Miller's fleld and seating patterns not only
have no connection to the qualities of its site, but they are also at odds
with the structure they inhabit.
The outfield fences have a gratuitous quirkiness. They take ten separate
twists and turns, supposedly to create better game action, but really for
little reason other than to be "interesting." Some of the classic
ballparks had as few as two or three outfield wall segments, and none
of them had such a voluntary fussiness. Among today's retro parks, the best
outfields have three to six wall planes. Likewise Miller's seats angle
in various directions, and the number of rows in the upper deck fluctuates
quixotically. Some of the angling improves horizontal sight lines, but that
doesn't explain the asymmetry--the alignments along the first and third
baselines differ, but surely one of them is better for viewing and should
have been the standard.
The Brewers claim that in designing the new park, they eliminated County
Stadium's 10,000 worst seats and then improved on what was left. Not so.
Even with a much smaller seating capacity of 43,000, Miller Park's worst
seats are further from the action than those of County Stadium: behind home
plate, the first row of the upper deck is more than 40 feet farther
from the batter. Most new parks claim to be intimate but are usually larger,
despite lower seating capacities. This is due to the lavish space devoted
to premium seating--the private suites and exclusive club seats--that form
the main impetus to build new ballparks. Still, among the 13 newest parks,
Miller Park's upper deck is the second worst in fleld proximity.
Most new ballparks claim to eliminate obstructed-view seats. In actuality,
they may eliminate views obstructed by columns, but other sight-line problems
are created because of stair landings, handrails, and upper-deck geometries.
At Miller Park, there are also columns in right fleld and in the upper
deck behind home plate, and the lower stands block views of the right and
left fleld corners from many seating locations. A more rigorous seating
design could have reduced these problems.
Given the innovative high-tech roof, one might have expected a modern treatment
of the exterior, but the Brewers' desire for nostalgia ruled that out. Meis's
exterior design is an honorable attempt to walk the line between postmodernism
and uncluttered expression--and is most successful in the facade's upper
reaches, where glass supplants brick. Seen from outside, the roof is somewhat
awkward, especially where its trusses converge in a crowded way at the home-plate
end. Its pivot points and drive mechanisms are hidden rather than celebrated.
And, like almost all retractable roofs, it is too big and prominent externally
compared to the stadium itself.
On paper, this detailed recitation of pros and cons may give the impression
that the stadium's failures eclipse its successes. But in execution, Miller
Park exceeds the architectural norm for a new baseball stadium: the roof
arrangement and internal circulation are outstanding, the scale is properly
grand, and the skillful provision of natural light is unsurpassed in a covered
ballpark.
