Shared space, accessible space

The best route from Vesterbro (my neighborhood) to Nørrebro (some friends' neighborhood) passes through a woonerf, or shared space.  Shared spaces are zones where cars, bikes, and pedestrians are on equal footing.  There are no sidewalks and no lanes.  The idea is that motorists are more attentive and drive more safely when they have to negotiate with pedestrians and bicyclists for the same piece of roadway.  I found myself at this spot today, and decided to stop and take a few pictures so I could share it with you.

If you'd like to see exactly where I'm taking about, click here for a Google map and streetview.

In this first photo we're entering the area from south.  You can see the special signage on the post that indicates this is a shared space.  The speed limit is 15 KPH, or a little over 9 MPH.  Notice all the people milling about in the middle of the road.  This how streets were used before the car was invented.  They were social spaces--maybe even the primary social spaces--as well as facilities for transporting goods and people.


Beyond signage, you can signal the transition to an environment like this by changing the character of the roadway.  You can paint a pattern on the road, or use a different paving material, like brick.  You can also change the grade of the road, giving travelers a physical cue that they're dealing with a new set of rules.  Here, Copenhagen planners used a subtle change of grade.



On the other end of the shared space environment we have these bollards, which allow bicyclists and pedestrians to pass while diverting motorized traffic.  Cars can still enter the site from the south, but because it's not a through route, volumes are low.


A playground blends seamlessly with the road.


Maybe you've guessed by now that I am a fan of shared spaces.  I've read the data and am amazed at how well they perform on safety, throughput, and aesthetics.  They should be deployed more widely than they are today.

One of the challenges that holds the shared space concept back is the fact they they can be disorienting to the blind.  Blind people rely on sensible materials and edges to maneuver through a city.  Take away the curbs, and you've taken away their guide rails.  With this in mind I took a look around this shared space to see if the city has addressed that problem.  I was pleased to find the following solution.

As you step into the shared space you are greeted by an array of metallic truncated domes in the pavement, which you can feel through your shoes.  These are similar to the yellow textured pads that you see on new crosswalk ramps in the US.  Leading from the array is a row of metal ridges that lead you across the square.  Let's pretend that black car is not parked over the ridges for a moment, shall we?



And ignore this shopkeeper's cart too.  Here we have an intersection of routes, and another array of dome to signal that you've reached a decision point.


True, these pictures reveal a flaw in the system, but in general I love the idea.

A confession

When my carry-on luggage gets selected for additional screening at the airport, there's a little part of me that's flattered by the attention.

Venice Biennale

Early last week I got back from the 2010 International Architecture Exhibition in Venice, also known as the Biennale.  It's a massive collection of exhibits by architecture firms from around the world.  The theme this year was "People Meet in Architecture," though it seemed to me that most entrants pursued their own ideas.  And some of those ideas were pretty far out: a cloud suspended in a room.  An array of hoses, hanging down from the ceiling of a darkened warehouse, whipping around as they spray water, illuminated by strobe lights.  Synthetic sea fans that twitch and move as you come close.  Check it out (plus my photos of Venice): http://www.flickr.com/photos/patrickandkristen/sets/72157625176397508/detail/

Ørestad Part 2

Continued from part 1

The first thing you notice when you arrive at Ørestad City--by bike, at least--is that it's difficult to tell that you've arrived.  After entering the site from the west I found myself in an ambiguous space surrounded by parking lots, a few department stores, and the rear ends of apartment buildings.  In the hour I spent criss-crossing the site, I never found the "100% corner."  I don't think there is one.  Not yet at least.

What I did find were some classic urban design blunders.


The elevated Metro line slices through the center of Ørestad from north to south, creating a ribbon of these shadowed interzones through the development.  While they've been spruced up with landscaping and water features, they still feel like smaller versions of the Alaska Way Viaduct: okay during the day, perhaps, but spooky at night and lacking in street life.  I'm not going to blame the designers of Ørestad for creating the problem.  I doubt the planning of the Metro was under their control.  But it is unfortunate that the physical center of this town is a series of underpasses.

Just up the street I found a much less forgivable condition.  Get a load of this facade.

There is no excuse for such an antisocial frontage in a dense, urban area--especially on a main drag.  In a city like Copenhagen this comes across as surprisingly inept.  I wonder how the development regulations missed it.  By the way, notice that utility cabinet.  After only a few years in this unwatched space it stands dented and vandalized.

Under the train tracks, on the east side of Ørestad City, we have the only collection of leased street-level commercial space I found during my visit.

You feel like you're about 2 feet tall while walking along this streetwall, thanks to that cladding that extends, unvaryingly, from the top of the entranceways to something like 50' up.  That's beyond your peripheral vision when you're looking straight ahead, so you get the sense that it continues up forever.  The outdoor seating is right there in the walkway, no awning, alcove, or ropes to give you some psychological separation from the public way.  Compare this to an image I took of the streetwall along the main drag of Greenville, SC (my sweetie's home town).  Where would you choose to sit to drink your cup of coffee?


There are things I liked about Ørestad.  All the residents are within walking distance of a Metro stop.


Between that and the long term plan for the town, which calls for a mix of shopping, employment, and housing, the vehicle miles traveled for Ørestad residents (and, consequently, their carbon emissions) will probably be low.  I couldn't read the Danish-language promotional materials, but I got the impression that the area uses advanced wastewater treatment techniques.  I'm sure the buildings are built to high environmental standards.  And then there's that wind turbine we saw in the previous post.

I liked the look of the buildings, generally.  They were fresh without any Gehry-like absurdity.



In other positive impressions, I was surprised at how much I enjoyed the central green.  It's a large space, surrounded by apartment blocks.  Here's a model of it that I spotted at Denmark's exhibit at the Venice Biennale, so you can get a sense of the scale.  North is toward the upper left.

 And here's a photo from the ground level.



I was prepared to dismiss it as Radiant City folly; Corbusier's "towers in a park" scheme was the inspiration for some of the most tragic and alienating urban planning of the 20th century.  Maybe it was because the sun was shining that day, or maybe it's because this area is new and entropy hasn't set in, but I thought the grassy area was quite pleasant.  There were families using the playgrounds.  Mounds--like you see on the left of the above photo--divided up the space into more manageable pieces, so you never felt overwhelmed. If I had to improve it, I would only add commerce to the center, maybe some food vendors, to give people a reason to visit and to create a hub for people watching.

...

Ørestad is struggling.  Many of the commercial spaces are empty and there aren't many people walking around.  That's especially disappointed considering how much I want places like this to succeed.  On paper it's doing the big things right.  It's got the density.  It's oriented around transit.  It mixes uses.  This is what we must do as a society if we're going to tame climate change and rebuild our cities.  Maybe Ørestad's slump will pass in time.  Maybe more residents will trickle in, and businesses will follow, and you'll have more people on the street than I saw.  But even if it fills up completely, you've got irreversible damage at the street level.  It's just not a pleasant place to walk around.


For example, look at the ground floor of the building to the right.  How could a sucking void like this have been constructed here?  Street-level garages like this one are banned along Eastlake Ave, a comparable street in my old neighborhood in Seattle.  Seattle's pretty progressive when it comes to urbanism, but I wouldn't expect it to outperform Copenhagen.  And yet here we are. 

I think part of the problem has to do with the way Ørestad was created.  A handful of architectural firms were given design control over individual portions of the development.  They each had a blank slate.  In that vacuum, with no context to draw upon, they all built monuments.  Nobody built the ordinary buildings that form the fabric of a city.  Don't get me wrong, I like monuments when appropriately spaced.  But a town that's entirely monuments is like a party guest who begins every sentence with the word "I."

The experience of visiting Ørestad got me thinking about a book I read recently, The Timeless Way of Building.  In it, author Christopher Alexander encourages the architecture and urban design communities to seek common languages of design, or "pattern languages."  Users of a pattern language are free to innovate within commonly understood limits.  For example, some communities might reach a consensus that the right height of its buildings is four stories, but that the colors should be up to the owner.  Like the syntax of a spoken language, a pattern language might also mandate that some classes of design features must be paired with others; buildings must have sidewalks or pedestrian pathways, for example. 

In Ørestad can you see what happens when builders lack a shared language of design.  Instead of a city you get a collection of buildings.  I don't know all of Ørestad's backstory, or who did what job.  But I hope as the city continues to develop the area it attends to this problem. Short of a consensus among architects about what constitutes good urbanism, we need someone overseeing these projects whose job it is enforce some basic constraints.

Agh! It's dripping funny smelling water on me!

I recently got an envelope from my sweetie back in the USA.  Oh boy!  As I handled it I noticed it was thicker than a sheet of paper.  I opened it up and tipped out the contents into my hand.

'Gee, how did these get past customs?' I wondered.  After dutifully swallowing a few and waiting an hour, my gut told me that maybe they weren't pills after all.  No, they were something much better: toy sponges!

Like Bart Simpson in 3F02, I had diabolical plans for these babies.



So I popped one in a glass of water.  It sat there doing nothing.  I poked it.  It bobbed.  I waited.  And waited.  15 minutes went by.  Then another.

Finally the gelatin coating dissolved enough to release its monstrous contents.  I peered down...


So I'm thinking,

Right?

But a few minutes later I saw that, in fact, I had a giraffe on my hands.


Majestic?  Yes.  Absurd?  Sadly no.

Ørestad Part 1

Sunday was a beautiful, crisp fall day here in Copenhagen, and I took the opportunity to visit a place I've heard a lot about: Ørestad. Ørestad is a “new town,” a built-from-scratch development outside of the city. Fellow students described it (positively) as a showcase of modern architecture, but always with the caveat that the street life “is weird” or “doesn't work.” The City of Bellevue, where I've interned for the past two years, is working with Sound Transit and the private sector to develop the areas around the East Link light rail stations, and this seemed like a good opportunity to see how Copenhagen—a smart growth giant—performed when it got a similar chance.

The Danish parliament passed the enabling legislation for Ørestad in the early 1990s as part of a long term plan to channel growth and boost the competitiveness of the region.  The Øresund bridge, which now links Copenhagen and Malmö, Sweden, was also included in that plan. The legislation created a company—jointly owned by the Copenhagen municipality and the state—to oversee an architecture competition and to develop the site. If all goes according to plan, Ørestad will some day be home to 20,000 people and 80,000 jobs. A strip of land about 3 miles long and 2000' wide, it straddles an impressive confluence of infrastructure: a regional rail line, a metro line, bus lines, arterials, and a motorway leading to the Øresund bridge. It's a monster TOD by Western standards.

I approached Ørestad by bike, across the Sjællandsbroen (“Zealand Bridge”) which connects mainland Copenhagen to Amager island across the Kalvebodløbet waterway.  You can see Ørestad rising in the background of this photo.

Ørestad's far enough from the central city that I'm guessing your typical cyclist won't be pedaling out there.  It feels like it's in the middle of nowhere.  

Speaking of, you might expect transportation planners to cut corners in this context, painting a bike lane instead of pouring a grade-separated cycle track, for instance.  You'd be wrong.  I was on paths and tracks the entire four miles from my apartment building to the site.  That's one of the great things about Copenhagen.  You can trust the network, even through the least-trafficked segments.  In the U.S. the infrastructure would have shriveled up and died on the side of some 50 mph highway, leaving me to white-knuckle it along the shoulder.  I'm convinced that, especially for vulnerable users, the chain is only as strong as its weakest link.

Moving on now.  Here are a couple of shots to show you just how strange this place looks from the outside.  You've got avant-garde, high-density architecture next to a wind turbine, next to...a huge empty field?

When I was a kid I read a sci-fi short story about the last humans on a 50th-century Earth.  They ran out the clock by sailing around and using nanoassemblers to conjure up replicas of cities from the wasteland.  I was reminded of that story while standing here, alone between the shiny new buildings and the not-quite-natural grassland of the Amager Fælled.

Balkans expenses

Kristen and I traveled through six of the Balkan states back in August, and it was interesting to see how much prices varied from country to country.  It felt like a big spread.  Since then I've wanted to see that data in a graphical format, so with some time today I went ahead and made a chart.  The green line is a three day rolling average, and the gray dots are individual withdrawals, with $0 values for the days when we didn't withdraw anything. 


As I remembered, Macedonia and Albania were the least expensive, with prices going up as you go north toward Central Europe.  The overall average day was about $125 for the two of us.  That does not include plane tickets, but it does include a five day car rental in Slovenia.  Not too shabby!
