Reverse Graffiti

A new kind of urban art has recently surfaced. It's called 'Reverse Graffiti' and basically involves artists graffiti-ing walls - but not with spray paint cans. Instead they scrub the grit and grime off dirty concrete walls and create fresh artwork.

The effect created is pretty neat while ridding the environment of the unpleasantness of grime and dirt. This simple idea really helps to beautify the urban environment. It's a pretty cheap and effective way to make an unsightly wall look a lot better. Perhaps it may even deter 'real' graffiti too..

Growth Concept

An assignment I completed at university in 2009 involved creating a Growth Concept Strategy for Rodney District, Auckland, looking ahead until 2050. This was assigned to us because Aucklands population is increasing steadily and Rodney District is a key area in which this growth can be accommodated.

A specific area of Rodney (Kumeu) was further examined. I proposed that 30,000 residents lived there by 2050 (a fair increase from what it is now). This gave a moderately high gross density of 41 people per ha.

The ‘pedestrian pocket’ theory is used in my proposed town design. The town will be developed along a linear pattern in line with a new light rail. ‘Pockets’ of development will exist along the light rail line. Each pocket will be of mixed use, however some will have more of a focus than others (eg.shopping centre, cultural centre etc).

This type of design allows for housing to be nearer services and employment. Many will be in 400m walkable distance, while feeder buses will be provided to others. In essence it is like a linear version of Ebenezer Howards 'Garden City' idea, very much focused on concentrated urban design as opposed to sprawl. In general I think the pedestrian pocket theory explained in The Pedestrian Pocket Book (1989) is an excellent idea, focusing on walkable, public transport orientated cities in a fairly compact form.

Building Typology

For a university assignment back in 2008, I had to explore different building typologies and the merits and disadvantages of each. I stated that it is important to establish the performance of different typologies when considering the development of an area where the inclusion of housing is concerned”. This is because different typologies have different characteristics. I assessed these characteristics against some basic criteria:

Private Realm: room size and shape, natural light and ventilation, orientation, noise, outdoor space, public/private front and storage space.

Communal Realm: mix of bedroom numbers within a building, number of dwellings, resident profile, safety.

Public Realm: walking distance to things, public open space, surrounding buildings.

An interesting example of row housing I found is located in Hatfield, London:

‘The Ryde’ is a fairly upper-class residential development in London. There are a total of 28 house units all on one level. It is an attractive neighbourhood, hence the development of aesthetically pleasing modern look buildings. They are 1 -4 bedroom houses thus providing for resident diversity.

The depth of the row houses means there are no windows either side. To provide natural light and ventilation however there is a patio centrally located in the larger houses. The inner court also provides a completely private outdoor space, along with the semi private front and back yards. Numerous skylights in the larger houses also provide light to the deep building layout.

There are several communal park/garden spaces and play areas such as tennis courts within the complex. These communal facilities would enhance rather than hinder residents getting to know each other. An unfortunate disadvantage is that directly to the west of the complex is a railroad running parallel nearby the length of the complex. This makes an otherwise short journey to several facilities more difficult as pedestrian movement is limited.

Housing typologies have great influence over the 'feel' and demographic of a neighbourhood, so should be shown great consideration when being considered.

Visualising Traffic Patterns

A guy named Pedro M Cruz has put together an interesting video. It's cool to see a neat graphical interpretation of something so mundane as traffic.

Pedro's explanation:

'One month (October 2009) of traffic information (1534 vehicles) is condensed in a 24h day. The arteries are colored in a way capable to represent average traffic speeds (the greenish and cooler represents high traffic velocity, and the reddish and hotter, corresponds to sluggish traffic). There is a visual emphasis on areas where the traffic is predominantly slow'.

Location: Lisbon, Portugal.

This video could do with some music though.

The Wall of Green

We hear of green roofs a lot but not so much green walls. This is probably because in theory it's great but in practice green walls take a lot of effort. However the latest large scale green wall has emerged on PNC Financial Services Group Inc's building in downtown Pittsburgh. 'The wall is made up of 602 two-foot square panels. Each panel contains 24 evergreen plants'. The panels were anchored into the buildings frame after some of the granite facade was removed.

Not only is this visually awesome but it obviously has environmental benefits. 'The vertical garden, similar to a green roof, will help to cool the 30-story building. Preliminary studies show the south-facing living wall will be 25 percent cooler behind the wall than ambient temperatures'. A man in the green wall industry states that 'green roof installations have increased at about 30 percent a year over five years'. However it will be a while until this idea is widely used because 'on average green walls cost about $100 to $125 a square foot'.

In the mean time we can admire the public art the walls inadvertently create, whilst wondering how the plants are watered in the summer and who prunes and takes out the dead ones...

Traffic Lights

This neat design by Damjan Stankovic called 'Eko', is an alternative to the traffic light's widely used now. The Eko light claims to help the environment and road safety. This simple concept is quite useful, allowing drivers and pedestrians alike see how long until a light phase ends.

'Since you know exactly how long you have to wait you can sit back and clear your head for a while. No need to keep your foot on the gas. Relax.'

This seems like a pretty handy idea, and would be helpful in reducing the stress and anticipation that can occur at traffic lights. Some people argue that it'll make people speed off faster. To help counteract this Stankovic has only designed for this technique to work on the red light as opposed to the green.

I can see this design being widely implemented, apparently similar concepts have been used in some countries.

Urban Design Argued

'The Value of Urban Design' is a report put out by the Ministry for the Environment, New Zealand in 2005. Basically it's a comprehensive document that details whether or not there is a case for good urban design. New Zealand doesn't really have an established history in the urban design department, with little robust examples. This document however is published to assist the public and private sector e.g. helping evaluate projects in the urban environment.

This document conclusively proves that urban design does have many benefits:

• Good urban design can offer significant benefits to the community; conversely, poor design can have significant adverse effects on the urban environment, society and economy.

• While good urban design sometimes costs more upfront, this is not necessarily the case; moreover, long-term costs can be avoided.

• Communities value the better quality of life that good urban design can deliver.

• Urban design can affect people’s ability and willingness to undertake physical exercise: good design can offer health benefits.

• Urban design can help make towns and cities safer and more secure.

• Urban design elements are interconnected: urban design is most effective when a number of elements come together (eg, mixed use, density and connectivity).

Evidence of the benefits of urban design were categorised under the following eight core urban design elements:

- Local character
- Connectivity
- Mixed use
- Adaptability
- High quality public realm
- Integrated decision-making
- User participation
- Density

Obama for High Speed Rail

Obama has recently announced his plans for the government to heavily invest in High Speed Rail (HSR). His package includes $8 billion for high-speed rail to be spent over two years and an additional $1 billion a year being budgeted over the next five years. He reasons for this large scale infrastructure investment:

"What we need, then, is a smart transportation system equal to the needs of the 21st century, a system that reduces travel times and increases mobility, a system that reduces congestion and boosts productivity, a system that reduces destructive emissions and creates jobs.”

“Imagine whisking through towns at speeds over 100 miles an hour, walking only a few steps to public transportation, and ending up just blocks from your destination,” Mr. Obama said. “It is happening right now; it’s been happening for decades. The problem is, it’s been happening elsewhere, not here.”

Americas current HSR is basically non existent as Obama points out. In terms of public transportation America is lagging in many aspects. Highways are congested and airports are getting increasingly busier, all impacting on the economic growth of the country. His desire for HSR stems from how well overseas examples have worked such as China's HSR system and the TGV of France.

Ofcourse, from a planners perspective it can be argued that HSR could lead to more sprawl. It is universally agreed, that urban living and compact cities are a more sustainable option than sprawl. HSR could encourage more people to leave the urban area and further influence suburban sprawl, creating more land and energy usage. However with appropriate land use policies in place, sprawl can be curtailed and rather the focus can be placed on Transport Orientated Development, that is building communities close to points of transit - limiting sprawl and encouraging more sustainable practises such as walking to transit points.

Under one of many of Obamas strokes of genius - public transport investment - one of the first initiatives of the HSR package is occurring in the Golden State of California. They have received $2.3 billion in funds to build an 800mile system that spans from San Diego to San Fransisco. This line is envisioned to provide many jobs, positive environmental benefits as well as decreasing the States dependence on oil.

The following videos are of respectively the graphical demonstration of the proposed California line, and the Business Plan of California's High Speed Rail Authority.

Developments in this groundbreaking USA project will be interesting to follow.

Planning as a host nation

For any country hosting a large event, major planning effort is required to cater to the influx of people and to also promote the greatness of the host city whilst it's in the international spotlight. Auckland will be hosting the Rugby World Cup in 2011. An issue that has been identified is the lacking provision of a large outdoor area for people to gather and celebrate. The Auckland City Council has bought a large wharf area, known as 'Queens Wharf'.

Design submissions have been called upon to develop this site. The vision for it is to be 'party central' for the World Cup. However, with the time pressure faced the site will be developed temporarily to cater to the needs the World Cup demands and a more permanent design will be put in place later on. This is a stunning site, and it would be a shame to make an ad-hoc permanent development there.

London faces a similar issue in 2012 with the advent of the Olympic Games. With this event being so large in scale, the city wants to portray itself in a positive light to the international audience, but likewise suffers from time constraints. Submissions have been called for a tourist attraction that can help symbolise the games and make the city stand out. A submission of note is 'The Cloud'.

This is a visually stunning but also rather complex design. It acts as an observation deck but also a broadcaster of information. Another neat feature is that it's completely self sustaining. Even though this monument may not be selected, the team working on it hope to build it. More information can be found at the projects website: http://www.raisethecloud.org/



Let's hope Boris Johnson really gets behind this!

As Monet said... “Without the fog, London wouldn’t be a beautiful city”.
