Floor area ratio : 155.3%Building coverage ratio : 40%The number of apartment units : 803

I designed the site with apartments bulidingsbecause Seoul, the capital city of Korea,has high demand for residental areas.

This development site is unique and will besynchronized with its neighboring communities.Pathways leading to the parks from theapartments, provide residents easy eccessto the outdoor green space.

In terms of safety, there are two entrances so that only permitted vehicles may enter. The main road will circle the site, which will beconnected to entry routes to each apartment.This will prevent from unnecessary driving.

City of Jinju is planning to build a new town todistribute the population around the capital city.For this reason, the plan to disburse the new urbanpopulation into the suburbs has been accelerated.

In order to revitalize the old town of Jinju city,three types of traditional and modern themed streetshave been planned to attract more people into this site.

Area : 1,039.8km²Current Population : 215,000Design Population : 260,000

From 1.4 cents to $6,400 per 1m². It showsGeumhak is the most expensive neighborhood.

Within the Okgye district in Gangneung, the amount of magnesium foundis the second largest in the world. A couple of new business in themagnesium industry are planned to launch in Gangneung.

Gangneung city is one of the most popular tourist areas in Koreawith attrations such as the beautiful Gyeong-po beach and Dano festival,which is part of Unesco world heritage.

Gangneung urban planning for 2035 is designed to accelate both thegrowth of the magnesium industry and tourism. GIS analysis was conductedto gain comprehensive plan. I planned 4 sectors; residental, commercial,industrial and green space based on a design population which is 265,000.

5 Urban Planning

New Town of Bubal

City of Icheon is a rapidly growing central hubin the IT industry. The city of Icheon has a concern thatthere is not enough residential area to accomodate the population growth with the current growth in theIT industrial area.

The Bubal area, which is located in the middle of Icheon,is scheduled to have a transfer station built so that3 different transit lines meet here. Also, Bubal is anoptimal area because it is in between an administration townand the biggest outlet mall in Korea.

I chose the Bubal area to develope a new town toaccelerate the IT industry within the Icheon district. I expectthe town of Bubal as a livable area by planning lots of community squares and green space in order to preventBubal area to become just a commuter town.

1. Bubal station is devide in the middle of the area. This may cause absence of communication between two areas. By planning open areas near Bubal staion, it will minimize this side effect.

2. Open space will be continued from Bubal square towards the north street. Commercial buildings will be set along side both streets.

3. R&D center and knowledge-based infrasturtures will be laid out along side the commeircial bulidings.
