Converting building for Housing




The Hub has been developed in the Netherlands as a way of converting empty buildings into comfortable housing is a short space of time. 

The Hub has been developed in the Netherlands as a way of converting empty buildings into comfortable housing is a short space of time. 

Hubs include a kitchen, a bathroom, toilet and provide heating, a sound system, an internet connection and are 15m2 in area. 

 More information is available here.
Scientists have claimed that 2015 was the warmest year on record. 

By using climate data from Accuweather, the New York Times have charted the range of actual city temperatures experienced for 2015 relative to normal the normal range.

Human Habitat Creation


Habitats are defined as the natural environment in which an organism lives, or the physical environment that surrounds (influences and is utilized by) a species population.

This was the subject of an Institute of Landscape Architects of South Africa (ILASA) Seminar on 11 May 2016 and number of interesting presentations were made by John Masson, Siegwalt Kusel and Ben Breedlove.



My contribution was titled 'Human Habitat Creation' and addressed the following questions:

  • What is a sustainable human habit?
  • What are the specific requirements for a sustainable human habitat? 
  • How can sustainable human habitats be achieved?
  • Can a structured process be developed to enable this to happen at a neighbourhood level?

The presentations led to a very interesting discussion on how  methodologies used by Landscape Architects and Habitat Designers to design habitats can be applied at a wider built environment scale.  Copies of the presentation on gauge site soon.

Why buildings collapse

Buildings in Kenya, Uganda, Rwanda, a bridge, a mall in South Africa, and a church building in Nigeria have collapsed. Building Investigators attribute these failures to:
  • Inadequate foundations
  • Poor and counterfeit building materials 
  • Workers making mistakes and a lack of supervision
  • Excessive loading 
  • Non-compliance with building regulations and a lack of controls

They suggest that often corners are cut during construction to maximise profit and that corruption is usually the reason that standards are not adhered to and proper checks are not carried out.

Integrating Informal Trade


City planning and urban design in many African cities are based on western and colonial standards that ignore the informal economy.  However, informal trade has been identified as one of the main sources of employment and it is estimated are that this provides between 20 and 75 percent of employment in many African countries. A range of benefits are associated  with informal trading including:

• Creates employment
• Requires very little capital
• Can improves security as there are more 'eyes on the street'
• Convenience, as goods and services that can be accessed easily
• Can improve street life and the vibrancy of an area or street
• Reduced transport impacts as local access is provided to services and goods
• Increased city efficiency as densities and trade is increased
• Improved resilience through diversity in the local economy
• Reduced cost and waste as repairs on items like appliances and shoes are carried out instead of these being disposed of

Despite these benefits, there is very little support for informal trade and many city plans and policies ignore informal trading.

Informal trade can be easily designed for in new streets and be supported through interventions in existing streets.  The example below shows how a city block, individual buildings and city furniture, such as bus stops can be modified to support informal trading.  These interventions are described below, with the numbering referring to the numbers in the sketch.

KEY

1.
Road
2. Pavement
3. Semi-private area that could be used by employees to access food provided by an informal trader who could also supply passing trade.
4. Food and beverage informal trader with stool seating that did not impinge onto pavement pedestrian traffic.
5. Small informal trading stall with awning which could sell small grocery or other items and receive power from the building. It can also be secured and closed off from the street. By occupying an 'indentation' in the building informal trade would not affect passing traffic.
6. Small lockable compartments where traders could park mobile sales trolleys and goods at night instead of having to transport these. During the day, these trolleys would positioned in street locations where traders would sell their goods.
7. A plant nursery run by an informal trader in a garden of an established local business. To reduce costs, traders could enter into agreements with landowners to maintain gardens in return reduced rental for prime locations.
8. A cafe run by an informal trader in a garden belonging to an established business. To reduce costs, traders could enter into agreements with landowners to provide in-house catering  in return for reduced rental for prime locations.
9. Trading locations designated on streets for designed for mobile trolleys which provide appropriate shelter and services such as power.
10. Bus stop
11. Informal businesses which are able to assist with some of the non-core services required by established businesses such as printing, stationary and courier services. These would be accommodated on established business premises and would provide services to both the passing other local businesses, passing trade as well the established business.

What Africa will look like in 100 years

Interesting article in the Daily Telegraph on ''What Africa will look like in 100 years''. It makes the following assertions:

  • By 2100, it will be home to 4.4 billion people - four times its current population.
  • By 2050, more than half of Africa’s 2.2bn people will live in its rapidly expanding cities. That’s the equivalent of the population of China.



Given the implications of this huge growth, it suggests that current development trajectories are not promising and may not be able to  "deliver on the aspirations of broad-based human development and prosperity for all". 

Solutions recommended include;

  • infrastructure that improves  education,health and security and economic prospects
  • sustainable governance systems
  • embracing new urban paradigms,
  • better data, better decisions and
  • diversified economies
