INTRODUCTION Bangalore, being the capital of Karnataka and a cosmopolitan city has been making strides in the fields of information, technology, aerospace, education etc. It has the distinction of being one of the fastest growing cities in the world. While concentration of such socio-economic activities within the Bangalore urban district has been continuing to attract significant immigrants into the region, the Government of Karnataka has felt the absence of an international standard airport, which forms the national and international gateway for traffic to Bangalore. Therefore, to bridge this gap and to meet the requirements of the anticipated growth in air traffic, a site near Devanahalli on NH-7 has been selected which is at a distance of 40km from Bangalore city center for constructing a new International Airport.

The corridor connecting Hebbal to Devanahalli comprises of various urban conditions which are highly transforming zones,a historic pricinct,the village agglomerations and ecologically sensitive zones. The present trends of developments indicates a generic built typology which is often the characteristics of corridors connecting metrocities to theInternational Airports.The process degenerates the Imageability of the area thus getting charecterised by huge glass boxes. Fig-2 Showing the Building development trend as on 2007
Source- Author This thesis is an attempt to understand the Airport corridor at its various dimensions and come up wth a design strategy. Which explores tests the strength of the local context in evolving legible corridor to the city of Bangalore from the International Airport. The thesis has also tried to demonstrate the strategies adopted.

2.Objective : Objecive of the project is to propose the design guidelines to evolve a legible & sustainable development along the Bangalore -International Airport Corridor. 3.Background : The Ministry of Civil Aviation of the Government of India had in the year 1994, approved the proposal submitted by the State Government of Karnataka to establish a new world class and modern International Airport for its capital city of Bangalore by private sector. 4.Need for the study : The rapid changes in the types of function,accomodated in buildings has resulted in programme less spaces or generic building typology. This can serve the link to its local context and hence a lost legibility. This thesis attempts to address this issue in the making of a corridor at its city level at the same time responding to the local imageability. 5.Scope and limitations : The methodology of this study can be adopted for fast transforming corridors in other Metropolitan cities. However the design strategies proposed are extremely tune to the local given situations. 6. Hypothesis : The corridors connecting International Airports to the metropolitan cities, located in its outskirts, have always generated generic built form irrespective of its local characterstics. This can severe the imageability the corridor to the local context.

7.METHODOLOGY : 7.1 Defining the corridor : Bangalore - International Airport Corridor is the one which connects Bangalore International Airport to the city at the Outer Ring Road.. 7.1.1.Location Bangalore is the capital of Karnataka situated at the south of India Fig- 3 Showing the Location of Bangalore in India.

This lane will have dedicated bus lanes which makes the spine very busy Also, a super fast railway connection is also being planned to link the airport and the city of Bangalore. The potential for fast transformation along this spine between Hebbal and the new Bangalore International Airport will be more than any other corridors of development in the city over the next few years. Hence the same is selected for study in this project.

7.1.2. Study area The airport has been constructed near Devanahalli about 40 kilometers from the city of Bangalore. The Bangalore International Airport is along the National Highway No.7. The length of the highway (about 23 kilometers) from the Hebbal junction on the Outer Ring Road up to the new Airport is the corridor selected for the present study.

7.2.2.5.Historicity. •Yelhanka is one of the oldest towns iKarnataka and is it believed that it has a history of more than 500 years. •As late as the fifteenth century, when Devanahalli, Doddaballapur, Hoskote and Yelhanka were formed, the original setlers had cleared the surrounding forests and started cultivation. •Jayagowda (AD 1418 – 1435) acquired the title of “Yelhanka Nadu” meaning “the Lord of Yelhanka” from the Vijayanagar kings. He ruled for 15 years and was succeeded by his son Gidde Gowda.Kempe Gowda (AD 1443 – 1453) son ofGidde Gowda was the most distinguished of the line who succeeded and acquired the favour of Vijayanagar Kings. As a reward, he got Yelhanka from Vijayanagar Kings. Fig- 13

Crops like Ragi should be made compulsary as it consume less water and also prevents soil erosion.Plantations like Honge trees should be encouraged so that it recharges underground table and it consumes less water .This also have Added economical value.
