Chapter 1. Brief of Competition
1.1 Title of competition : Bcome 2020
– International Ideas Competition for Community Housing Model Proposal –
1.2 Site location: the whole area of 66, Sujeonggongwonsang-ro, Dong-gu, Busan, Republic of
Korea (Gugil Apartment)

The general condition of the project site

1) Land Area: about 11,757 sq. m.
2) Use Area: second-kind general residential area
3) Building coverage : up to 60%
4) Floor-area-ratio: up to 210% (adjustable within the range of ±5%)

1.3 Background
1) In the era of super-aging and depopulation, Bcome 2020 is to discover new community
housing models that can cope with the obsolescence and deterioration of a backward housing
on the urban hillside of Busan, as well as to review the feasibilities of proposed models and
apply them extensively to adjacent similar areas.
2) The main purpose is to develop low-rise housing models considering local characteristics and
the public good of housing stability for the socially vulnerable populations, exploring how to
realize the architectural-urbanist models of “inclusionary city” like the social housing promoted
by the present Korean governmental policy.
3) Our programmatic suggestion of social housing is to enable the resettlement of existing
residents as an alternative to the existing practice of urban renewal due to urban deterioration
and hollowing-out, exploring how to provide the sustainable rights to housing for the
socioeconomically vulnerable, improve the environment for their stable dwelling and maintain
their community.
4) It is primarily to develop social housing models by the public expenditure for the
neighborhood living facilities as social overhead capital to secure urban infrastructure and for
the reconstruction of collective housing to improve dwelling environment.

Chapter 2. Basic Guidelines
