1. URBAN PLANNING AND URBAN DESIGN NKUMBUYABERA Esdras Portfolio 2. URBAN PLANNING STUDIO LOCATION: The site is located in Kigali/Nyarutarama/ Kangondo II. PROJECT OBJECTIVES: The aims to upgrade a slum know as Bannyahe. In the neighborhood analysis we identified several features such the topography, the wet- land which takes the lower part.Many and highly densified houses are in the wetland without toilet,dranages,.... However there are some facilities; water, electricity, shops, and the road . The project of Bannyahe upgrading was done through community participation where we were able to know their preferences and different information of people living in the neghbourhood. Many people staying in the neighborhood do not work in it, there is daily movement of people from the neighborhood to their job,students going to school. Mostly women are found in the neighbourhood in working days due to that they stay at home taking care of kids(Insecurity) 3. Together with the community we decided to have a neighbourhood with improved living condition,which is self reliant and facilitate interaction and recreation of people to be our vision for Bannyahe. with different objectives, strategies and inter- ventions. We defined different main urban nodes in the neighborhood, where we have transport node at the main entry,Commecial node, administrative node, educational node and community/social node, related to their programs; car parking, market,cell office,school and community center respectively. OBJECTIVES STRATEGIES INTERVENTIONS infrastructure SERVICES, FACILITIES AND PUBLIC SPACES HOUSING Promote easy accessibility and movement in the neigh- bourhood Provide a good infrastructures network Creation of job opportunities Provide recreation area and diversity of services Use renewable energy Improve safety and comfor, Avoid relocation Create main roads and upgrade the existing. Improve pedestrian circulation. Collecting and recycling water from dwellings Creation of cooperatives Increase green area and public spaces Provide education,administrative and commercial node Use biogas and solar energy Improve quality of the dwellings Unification of plots(clusters) and construction of apart- ments constructio of roads:external and internal roads and upgrading the existing. Construction of water treatment infrastruc- ture &drainages combined with paths . Construction of school,market and community center;Creation of parks, public plazas Construtruction of energy facilities and coop- eratives offices. Use of materials which do not have nega- tive impact on human being at the same time affordable. Cattle & pigs keeping Parking Garage Church Carpentry& Welding workshop Market DispensaryE nergy center (Biogas) Wetland park AgricultureCommunity center Natural park Mixed use houses Medium rise residential Low rise residential Single residential The new land use was defined according to the exixting conditions, where commercial activities an high density are on the upper part, going down the density decreases from apartments to single family residential. Sanitary sewage are treated, using a principle of gravity to remove and treat wastewater and water is reused.There a Biogas digesters that produce cooking gas and fertilizers, and grey water is re-used for irrigation and fl ushing. Trash are collected and recycled at the environmental treatment zone(ETZ) and ETZs are located at the bottom of slopes, where gravity brings waste to be treated environmentally. 4. Master plan implementation: PHASING The implemenation is divided into four phases where the main starategy was to create cooperatives of plots owner (plots to be combined to form cluster) and start marking where new roads will pass so that people are informed that in next phase they will be moved and reactivating the existing cooperative of people working in the existing market. The other action was to start constructing apartments in the vaccant plots found at the upper part of the neighborhood, where people will be moved to.(to develop new roads and move people from the wetland. In the fourth phase(After 25 years) all works will be completed through in-situ upgrading and Bannyahe neighbourhood becomes A neighbourhood with improved living condition ,which is self reliant and facilitate interaction and recreation of people. Some Urban guidelines were designed to respect master plan implementation,such as storm water collection, sewage treatment, road setbacks to provide linear parkings along streets, providing spaces for kitchen gardens,.... 5. URBAN DESIGN STUDIO PART I: Travelling for case study, KIGALI_ KAMPALA_ NAIROBI. PART II: Urban design project in Kigali heritage village(CBD) The trip stared from Kigali , where we experienced diffferent public spaces, used differently, In travel I looked at how pedestrians use roads vis a vis vehicular movement, where It was found that in some roads cars consume pedestrians walkway, and it highly affect their confortability. Kist to town(Kigali) pedestrian walkway is defined by curbs with paved area and the path big, however there are bigger trees(Greverea robusta) planted in the mid- dle of the path, which consume that walkway so that when two people meet, one should go in the road. There was an opportunity to experience different types of road and how they are used, looking at the relationship public spaces and human being. Entebbe road(Kampala) is quite big, with pedestrian walkway, and a space reserved for street vendors in front of shop, however the pedestrian walkway is defined by only line(paint) in the road so that when cars are overtaking(during traffic jump) they consume it and the road is always full of cars in the morning and the evening time. In addition some building consumed street vendors space( Florida hotel) which make them to go in the street. Nakuru to Nairobi road is a bigger road with a system of four one way roads, railway and protected walkways so that pedestrians are comfortable due to that they are separated by cars by a line of trees and grass. The experience of high traffic roads was gained, looking at how building along these roads react to let people get in, some buildins are opened up to three floor fo exhibi- tion, which gives another quality of space, and make shops part of public space/ road. In Nairobi city , the analysis was about understanding how pedestrianss spaces are working in vehicular setting, The analysis was done on three different public space, but linked together by green connectors. These are: Bomb blast memorial, Aga Khan walk and Tom Mboya statue. The facade is opened from ground floor up to 3rd floor to diplay different goods Namirembe road, the street is busy with alot of people and big public cars are found due to that it is nearby bus terminal. When you reach open public spaces, you start to have a long view which actually blocked by tall buildings in other part of the city, and different building with differ- ent features are found in Nairobi. Cental park KICC Library NAIROBI Bomb blast memorial Aga Khan walk Tom Mboya statue Hilton park Car parking Bus stop Pedestrian connection 6. Some roads are one way to increase pedestri- ans walkways( Mamangina Street) The walk is located nearby the bus stop so that some people use it while waiting for bus or their relatives especially when it their first time in the city(reference point). Creation of linear parkings along streets and pedestrians paths have been made bigger .Integration of Green connectors( Sheltered pedestrians paths connecting public spaces). Car parkings serving public spaces and nearby buildings. BOMB BLAST MEMORIAL TOM MBOYA STATUE Nairobi has alot of vehicular traffic, especially in pick hours hen people are going to work in the morning and in the evening when they are going back to their homes after working hours. These public spaces are found helpful in the urban context, for they help people to relax and enjoy urban area, spaces are used as resting area, reading area, conversation, and gathering, In addition many people prefer to walk in city than using cars for transport. AGA KHAN WALK PART II: Urban design project in Kigali heritage village(CBD), The project aims at creating a passage connecting two different blocks that are separated by road( proposed to be pedestrianised by Kigali Master Plan) and within a block there is no continuous path. These blocks has a religious landmark(Inkurunziza church) and it is bounded by the road which connect other two important element of the city;Market in West and future city hall in East. These three elements are found to be important and it relevant to create a passage which connect them. EXISTING LAND USE Nyarugenge market City hall Church 7. Many houses in these blocks are only ground floor and others are one story, There is a road with a bus stop and many people are standing while waiting for the car. Buildings facing the road have porches which are used differently, sitting,display and walking and stairs are used as seats. There are different features within blocks that can be im- proved and create good spaces,including courtyards, corridors,...However some of them needs programs that may activate them, and others have poor quality of houses. The road Kazi ni kazi courtyard The corridor is directly connected to the pe- destrian street,but it is not active because buildings along it are storages. This view seems to be an entrance from the pedestrian street to a block with Inkurunziza church, with a small building which defines privacy of residential building which is on one side. The courtyard has a garden with storages and an office and at its entrance there a small canteen which make it active. Kazi ni Kazi Entrance They attached a wooden truc- ture that is used as exhibition along the corridor. Three important elements of the city were identified(Main gathering spaces) and the concept is to connect them and creat
