Folsom Powerhouse is between phases, Awesometown is soon to begin and Pop is selling… Sure we’ve got Duplexcellence II to worry about but that still leaves us with some free time to get back to blogging. So we’ve decided to pick back up with Jane Jacobs and continue our Urban Planning 101 series. This time we’ve been reviewing “Border Vacuums”, which are a cool concept especially in conjunction with mixed use neighborhoods. Cool, like new rubber bands on your braces cool.

So what exactly are border vacuums? And where can I get one?

Yes, it is a great name for an as seen on tv product but, “Border Vacuum” is really just a simple urbanist term used to describe  any long, single use territory.  I-676 for example as it cuts through Center City and particularly Old City is a border vacuum.  The Delaware river, I-95 and our network of rail lines are all classic examples of Border Vacuums. Less obvious are large shopping plaza’s, parking garages and blocks of solely 9-5 office towers. In all cases these areas form borders for pedestrian activity. Their single use, although it may be a pedestrian draw like the 9-5 office tower, creates a void in the otherwise chaotic variety of uses that makes a city exciting.

As the variety of uses declines so will the number of pedestrians on the street. The border vacuum has the effect of sucking the life out of the city directly adjacent to it. That’s where Jacobs got the vacuum part of the term… we assume. Either way the effect of border vacuums is the creation of an edge, where pedestrian life forms a void and everything lies quiet.

To help us visualize this, and because even we wouldn’t read this if it wasn’t broken up with pictures, we made a map of Philadelphia with all the borders as defined by Jacobs removed from the map. First we took out the rivers, the most obvious borders, then large stretches of open space, the used and unused rail lines, large highways, and really wide streets. What we are left with is a city divided up into smaller sections.

If we were to compare this to a map of Philadelphia’s neighborhoods we would see that many of the neighborhood boundaries are the border vacuums we’re talking about. This doesn’t work exactly for every neighborhood and some of the zones on our map may contain 2 or 3 neighborhoods, but as long as you don’t hold us to a strict interpretation, this remains true. Now before we start arguing about where your neighborhood begins and ends I should mention that neighborhood boundaries aren’t an official designation. Neighborhoods, aren’t even an official designation. After all you don’t cross a line and go through customs but they do sell different kinds of  beer and the ethnicity of the ethnic food has changed. So uhh, disclaimers aside, once we zoom in you can see those “neighborhoods” take shape. (FYI in these zoomed in maps we removed giant shopping plazas and parking lots as well since they are also borders. It was too much work to do for all of Philadelphia.)

Borders are important in defining neighborhoods but clearly a lot of what lets you know you’re in a new neighborhood is the disparity between them.  Whatever it is, one neighborhood has a different feel than the other. One might feel safe, the other kinda iffy, one might be bustling with people while the other may be mostly trash tubleweeds. This is where “Mixed Use” comes into play. If you’re a loyal follower of our blog you already know from our first Urban Planning 101 post that “Mixed use” is the backbone of a healthy neighborhood. But in case you forgot exactly what that means; mixed use neighborhoods are neighborhoods that have a variety of uses (Residential, Commercial, Civic, Industrial,). Not exactly an earth shattering concept, but the important thing behind it is that a mixed use neighborhood will have pedestrian activity on the street at all times of day; people going to work in the morning, doing some shopping in the afternoon and going out for a drink at night. Having people on the street is what keeps it safe and interesting. Take a look at those same three neighborhoods but now with commercial space overlayed on top. Info courtesy of google maps.

 

In these three neighborhoods you’ll notice a line of yellow starts to emerge. That’s what we’d call a commercial corridor, and it’s the hub of pedestrian activity. From our perspective as developers, Philadelphia seems to range from these healthy urban neighborhoods with a lot of pedestrian activity, the ones seeing massive redevelopment, to sadly unhealthy neighborhoods that have changed little since the loss of population that shook Philadelphia from a city of 2 million in 1950 to a city of 1.5 million 50 years later.

This dichotomy occurs where it does largely as a result of border vacuums. Taking a look at these three neighborhoods, which are not seeing massive redevelopment, you’ll notice there is really no yellow line emerging from the dots. Point Breeze has a few blocks along Point Breeze Ave and some rumblings of commercial space along Passyunk Ave but nothing definitive. That Passyunk commercial space is also fairly car-centric as Passyunk widens west of broad, and was something we debated cutting out as a border. The same story occurs in Port Richmond. The yellow dots begin to coalesce on Allegheny Ave, but just barely, and its girth also puts it in the “almost border” category. West poplar is nearly commercial-less, with some transit oriented commercial happening at broad and Girard. But this is mostly fast food and it happens at the intersection of two borders.

You may have noticed we’ve compared only neighborhoods with healthy street life that lie next to ones with unhealthy street life. This being about borders we needed to take two neighborhoods undergoing very different development conditions and see what happens where they connect. Fishtown and Kensington, with hip Frankford Ave, have been booming for a while but Port Richmond has seen very little redevelopment. The 25+ foot high Lehigh Viaduct, which brings that commercial activity to a halt, is the border there.

 

Similarly The graduate hospital extravaganza hasn’t been able to do much passed the Washington Ave border. Once our map removes the big box stores that are a car draw before they’re a pedestrian draw that Washington Ave border grows. And is enough to isolate the healthy street life of Graduate Hospital.

 

 

NoLibs and West Poplar are the same story. Two neighborhoods side by side, one developing out of control, the other has been modest. A gentle fade, then a border is the culprit here. Although the low density housing of West Poplar plays a large role as well by preventing higher density of urban living (something that tends to lead to a higher density of commercial activity).

The surges going on in the booming neighborhoods like Fishtown/Kensington isn’t likely to spread across they’re respective borders any time soon either. If it did the people living in Port Richmond would still have a 5 minute walk passed some industrial land, under a gross tunnel and across Lehigh to get to anything Fishtown has to offer. For Port Richmond to see the same surge in development that Fishtown has it needs to develop its own variety of uses and create its own central hub of excitement. Border vacuums divide the city into smaller sections. Those sections then have to be able to stand on their own in terms of healthy street life. No leeching off your neighbor.

All in all border vacuums have gotten a pretty bad rap, and for good reason. Unfortunately they are an integral part of what makes the city a city. After all the city wouldn’t exist here if it weren’t for the two rivers converging. And the rail lines which were an integral part of our cities industrial past are still used to transport goods in and out.  They define the urban landscape as much as they divide it. The key is to manage borders well, to add uses in each segmented area and to bridge and connect the areas that are too small for many uses.

It is important to note that successful commercial space isn’t necessarily the thing to promote massive development, nor is massive development the thing to promote successful commercial space. It’s a little bit of both happening at the same time. The main take away is far simpler than that, (this is 101 after all). Hopefully we’ve shown that border vacuums dictate where the mixed use needs to be and that healthy urban neighborhoods cannot happen without their segmented area containing a variety of uses. That means planning for the density that will necessitate those uses, encouraging mixed use developments and live/work developments and incentivising transit oriented development while de-incentivising car oriented development. And of course, equally important to having these things is having them all in the right spot, in the right segmented area.

Open House Saturday Sept 13, 11:00 – 1:00

2037 + 2039 Blair St.

3 Bed, 2 Bath, Roof Deck – 375,000


Plans for the weekend? Why not visit one of Philadelphia’s hippest neighborhoods and come take a look at our Pop! project, the nations first cork clad homes. We had some help from our good friend Andrew Rottner staging these to bolster our photo archives and we’d love to show it off. Rarely do we get to come in and take pictures of a “lived in” home, so this is an exciting opportunity for us.

It just so happens that this Saturday is the “End of Summer Block Party” on Frankford Ave, complete with food trucks, a DJ and plenty of local vendors, (maybe a soft opening for the new La Columbe, well see). We recommend stopping by our two homes on Blair street around 11 or 12 and then heading south to the block party. That will get you there exactly fashionably late, or on time as we like to think of it.

Take a look a some of the preview pictures below if you need some more enticing.

Open kitchen complete with Bosch Appliances, Grohe Fixtures and custom Posgtgreen Homes oak or walnut cabinet fronts.

Check out that accent wall. Along with the 11′ ceilings this living room has some style. Solid white oak flooring throughout with a natural finish contribute to the durability.

Cedar Decking and a very streamlined back yard. Landscaping complete!

The master suite with customize-able Ikea storage options…

Attached bathroom…

And luxurious roof deck.

Of course the cork, and lots of it. 3″ thick for added insulation and soundproofing.

2037 and 2039 Blair St.

Just off Frankford ave in Fishtown: Three Bedrooms, Two Baths, and Roofdeck. Also Cork. Lots of Cork.

 

Construction is complete on our long awaited Pop! Project and we’re pleased to announce its release on the market! These two have been getting a lot of interest as the first homes in the United States to be clad in cork. If you’re interested, Treehugger wrote a nice article about the benefits of cork as a building material.

But for those who would just like a quick refresher look no further. Cork is way more durable than you would think. It has a natural waterproofing agent called suberin which keeps it from absorbing water, also keeping it mold free. The suberin when heated also acts as a binding agent meaning that toxic glues are never used in its production. Over time the cork will fade, but as the seasons change so will the color. It gets browner in the winter and more orange by the end of summer. That’s all good news but what attracted us to cork is its value as an insulation material. We use an exterior insulation on all of our homes which will then get covered up with usually steel or fibre cement cladding. On Pop we were able to maintain the same R-value with 3” of cork and forgo covering it up with cladding. Cork has been used as a cladding material before on many homes in Portugal, where most cork is grown, but Pop is the first in the U.S.

Designed by Netherlander Jefta Van Bellen of Orange Concept, the unique design does not stop at the façade. Head inside and take a look at the accent wall of your living room. Covered in a layered cork tile this wall highlights the 12’ ceilings and really puts us on the map as far as cork purchasers go.

Another first for this project is our custom designed and fabricated, Postgreen Homes cabinet fronts. Tired of the old Ikea fronts we decided to test out the process of fabricating our own simple, modern cabinet fronts. ¾” Apple Ply in Oak or Walnut painstakingly hand finished provides another unique element to what is already not your typical row house.

A quick verbal tour- The second floor has a bathroom and two loft style bedrooms with options to be closed off. Going up one more leaves you in the master suite looking out on to your roof deck facing Frankford Ave with a distant but unhindered view of center city. This is a great spot to… I’m sorry I can’t resist… “pop” the cork  on your favorite bottle of wine and soak in some rays.

All bad Pop puns aside these homes truly reflect the design stance of Postgreen, with innovative cladding materials, modern design, all of our usual sustainable features like thick insulated walls, efficient appliances durable and low VOC materials. Adding one more, this project represents a commitment to local design and fabrication. Starting with our architect, Jefta of Orange Concept who lives in Fishtown, to the to the USA made products like our new light fixture options from Cedar and Moss and The Good Flock there is no shortage of local craft in this home. Our new custom cabinet fronts top it off with some made in Philly talent. If the cork wasn’t from Portugal we might be talking about Pop as an American made home.

So come on by and let us know what you think of these homes.
