I've been a guide at two of the three Wright buildings in #27 (quoted in #46), so I have predictably more affection for them than most here. The post makes its point largely by selecting unflattering photos, like those no-makeup ambush shots of tv and movie stars we see in the supermarket tabs. Ennis was much altered for the worse in the building (after Wright had moved back to Wisconsin and left his son in charge). As drawn it was far more delicate and angled to fit the landscape without so many opressive right angles. The jarring contrast between natural dark-grey concrete and off-white. The Hollyhock photo dates, I suspect, from during or shortly after the 2000-2005 restoration, when the lawn was neglected (and the lawn is the really ugly part of the photo). The jarring two-tone color scheme juxtaposes the original color (grey-green, above the cornice) with the inauthentic sandstone pink of an earlier restoration. Imagine all the stucco in grey-green. More importantly, see these buildings inside if you get a chance.
Finally, German is a warehouse. It should be secure and well-insulated and should look it. By those criteria it succeeds.
