Sure, its a great question. (This is all my opinion by the way)
This is all a matter of scale. The south end has narrow streets made for walking. And the uniform facades that have a slightly different look every 30' are perfect for the human experience of walking down that scale of street. There is a cadence. A rhythm that just works for people walking on a street like that. It connects to your internal clock. Ever notice that you have a better sense of time walking down Newbury Street vs Boylson? I do
While the material qualities of Comm Ave are heightened. Stone vs Brick or Granite vs Brownstone or just Better detailed brick vs brick. (which is actually the real condition believe it or not) The relationship to the scale of the Avenue and the height and lot street frontage has been maintained. (I am not sure by what mechanism but somehow it was. probably economic). Because of the promenade and the two lanes of traffic on either side ... the pedestrian experience shifts and now the buildings can be a bit taller and a bit wider and still have a sense of rhythm and cadence when walking by. As far as being statement building after statement building. I am not sure I agree. Look at the linked picture.(below) There is mostly texture buildings, nice ones, but texture still. There is ONE image center that is clearly telling you to take notice. But even that building is playing pretty nice with its neighbors.
A couple key points for both the South End/Comm Ave/Newbury Street are that there are:
- multi-parcel blocks
- an overall uniformity of scale (height and street-face), materials (in both cases brick with a punctuation of other materials.
- Some slight variability in both scale, materials, height, and street face. It is a richer more interesting experience if things DON'T all line up. No great street has all the cornices lined up. Look at the Parisian Boulevards. All of those buildings have about the same elements on the facades .. their properties just wobble a bit. This brings a sense of delight.
What are the things we do wrong in the Seaport/Kendall/Every F'n Other Place?
Well. Its the economy stupid (without other good urban controls). First of all. Multi-Parcel blocks are an anachronism. The economics of building in an expensive urban environment are such that to make the requisite "killing" it makes not sense to build one stand alone chunk at a time. Superblocks are king and will not go away.
There is much more opportunity and much more desire to be a standout. I think people don't understand why the south end and most of Boston, and most all New England Cities are predominantly brick. The reason that I know is that it was code driven. After a number of disastrous fires in Boston, the city required by law that all buildings had to be made out of fireproof materials. The cheapest way to do that was with brick. When someone wanted to stand out, be unique, they went to stone. There were NO OTHER OPTIONS in the 1800's. No terra cotta (sorta), no metal panel, no cement fibre board, no precast concrete. The options were limited. Peoples houses/buildings stood out in the smaller details and those details were based on what they could afford. Some people had jack arches, some had, granite lintels, some had copper bay windows.
Now ... we have a personal expression pasted onto every building. AND it gets a name too. Troy,Watermark, Watermark2, Watermark2.1. (although the naming is not new, how we name them is).
In the end, what we have chosen to ignore is the human scale of cities. We build at the scale of the proforma, and unfortunately, the proforma does not have human health, comfort, and delight baked into it. (at least not often).
Whew. Sorry for all of that.
