With the increasing demand for public housing, the Singapore government decided to reduce the waiting time of future public housing owners, which requires these projects to be completed on time. As a result, this study aims to identify the frequent and impactful factors affecting schedule performance of public housing projects in Singapore. The survey conducted with 36 industry experts revealed that "site management", "coordination among various parties", "design changes by owner during construction", "availability of laborers on site", "availability of material", and "availability of staff to manage projects" were the six factors that should be emphasized to assure the schedule performance of public housing projects. In addition, there was statistically significant agreement between public housing projects and other building projects on both the frequency and impact ranks of the factors. The findings from this study will help practitioners involving public housing projects to take measures to assure the achievement of project schedule objectives.

The purpose of this study is to analyze the design characteristics of external appearances of Hundertwasser's housing projects through both literature review and field study, and to understand how Hundertwasser's architecture philosophy was embodied in the design of external appearances so such projects. The subjects of the analysis are: Hundertwasser House; In the Meadow Bad Soden; The Forest Spiral Darmstadt; and The Green Citadel Magdeburg. The conclusion of the study is as follows. The fundamental architecture philosophy of Hunderwasser is the close linkage between mankind and nature. He has proven, through his four housing projects mentioned above, that it is possible to build houses without destroying and in harmony with nature. Hundertwasser had identified vitality, irregularity and diversity as being the source of beauty of nature. Using the human creativity, he had embodied such elements into his housing projects, thus suggesting an ideal housing environment whereby humanity is respected. Hundertwasser made use of organic curved line and spiral shapes that exist in nature when designing his housing projects. His creativity was articulated through vitality, diversity, and irregularity in colour schemes and a wide range of form. Indeed, he was an architect pursuing the underlying nature of both human and nature. The current living environment in Korea can be characterized as being standardized and desolate, which is a result of housing projects being focused too much on functionalism. Through its analysis of Hundertwasser's housing projects, one of the objectives of this study is to contribute to a new design paradigm being called for today, including for housing projects to be more ecological and environmental-friendly. By motivating architects and appealing to their clients, this study hopes to motivate those involved in various housing projects to think progressively. Such an attitude change could assist in transforming and thus enhancing the overall living environment in Korea.

This research is an effort to clarify the causes associated with the 'failure' of public housing projects built in the 20th century. Two of the most brutal symbol of failure were selected: the Pruitt-Igoe built in St. Louis, U.S.A. and the Bijlmermeer in the south of Amsterdam, Netherlands. Many critics have attributed the problems of the selected housing projects to architectural failure, and proposed a series of new approaches to architectural design. The claim that many housing projects 'failed' because they were based on an agenda for social reform, derived from the ideas of the CIAM, presupposes that architects were in the position of authority over providing housing for the poor. This research tries to overturn the belief of architectural community which has placed the responsibility for the failure of public housing on designers. The sense of isolation and powerlessness felt by the residents, and the social problems attendant on those feelings, may be reinforced by design but is not caused by Modern Architecture. It should be stressed that the political-economic and social context is more significant than the architectural design for the failure of public housing projects such as the Pruitt-Igoe and the Bijlmermeer.

This study proposes a new housing need and demand assessment model centering on small-scale housing development projects and happy house development projects that reflected the recent changes in rental and small sized apartment centered public housing policies and development paradigms. The housing need and demand assessment model of public housing development projects consists of quantitative evaluation factors such as potential need indicator and demand pressure indicator and qualitative evaluation factors such as local condition indicator. The potential need indicators of small sized housing development projects are calculated by subtracting the stock of already-supplied constructed rental and purchased rental housings from the potential quantity of need drawn from the small regions such as -eup, -myeon, and -dong. In the potential need indicators of happy house development projects, the potential need is calculated from those who are expected to receive a happy house in the unit of -si, -gun, and -gu. In small-sized housing development projects, demand pressure indictors are the number and the proportion of those who opened a subscription deposit, the number of those who received basic livelihood security and the number of those who were patriots and veterans. The demand pressure indicators of the happy house development projects are stock ratio of small-sized houses, rate of rise in housing rent price, level of housing rent price, and rate of monthly rent house.

This study aims to introduce "Street-Housing" Redevelopment Projects adopted by the revision of regulations in 2012 and promote them by surveying residents' needs. The objectives of the street-housing redevelopment projects are to maintain existing street systems and redevelop housing by small units, as an alternative to the large-scale housing redevelopment by the expropriation. Residents, however, do not seem to support the new projects since they are satisfied with their current housing, have difficulty in raising funds, and are uncertain about proceeding with the pre-arranged. Despite these barriers, residents may support the projects if project charges can be lowered by the reduction in each resident's share and the increase in supporting funds. This study proposes new practical methods for realizing the projects: choice of an appropriate site, engaging for resident's participation in projects, reduction in project charges, and removal of barriers to co-operative development. etc.

In this study, the current conditions of the farming and fishing village housing improvement projects that were promoted for the last five years were examined, the results of the survey conducted among the promoters of the farming and fishing village housing improvement projects with regard to their level of satisfaction were analyzed, and the outcomes of the housing improvement projects and the improvement needs were derived for utilization as basic data for preparing an improvement plan for "the farming and fishing village housing improvement projects". Below are the results of this study and the proposals based on such. In view of the reality that the recipients of the farming and fishing village housing improvement projects are limited to the rural residents who are able to repay their loans, ways of actualizing the current loan limit of 60 million won should be prepared, taking into account the actual construction cost. Moreover, as the rural residents do not live on monthly salaries, the repayment periods of their loans should be adjusted to make them payable on a quarterly or a semi-annual basis, reflecting the reality of the farming villages, where loan repayment is based on the residents' yearly income. Further, policies guaranteeing the residential rights of those belonging to the low-income bracket who are unable to repay their loans must be established at the soonest possible time. In view of the realities in the farming villages, where there are 640,000 houses that are over 31 years old, the supply of 10,000 houses as part of the housing improvement projects is grossly inadequate. Of course, it cannot be said that all the residents who are living in worn-out houses have the necessary conditions for receiving support from the housing improvement fund. Therefore, policies supporting the speedy improvement of worn-out houses and guaranteeing the residential rights of those belonging to the low-income bracket are urgently needed.

The purpose of this study is to suggest diagnosis indicators and checklist for urban regeneration projects by Korea Land & Housing Corporation(LH). There are already deprivation indices in the Urban Regeneration Act but not any additional guidelines in the practical aspect. In order to use the diagnosis indicators, the central government should supply more specific checklist to the actors in the regeneration field. The key actor of many stakeholders is LH as an operator and implementer in the regeneration projects. So far, LH has developed housing and cities and there haven't been any obvious changes to realize public benefit in the deteriorated area. From now on, It has to plan, implement, and manage a lot of regeneration projects entirely. Therefore, It is necessary to develope and apply the diagnosis indicators and checklist based on projects. This paper came up with the 6 factors related with LH business field : housing, urban infrastructure, public service, private service, environment, and smart city. For these, 32 diagnosis indicators and 72 checklists were selected that can include both physical and qualitative indicators. These can be used not only for the selection of regeneration projects but also for the process monitoring such as planning and implementation.

While many studies on feasibility analysis for housing projects have been released, the main focus was on economic feasibility and factors related to developers were not clearly identified enough to be used in practice. In order to establish a feasibility analysis model for apartment development projects requested by developers in Korea, 31 driving factors behind projects' success were identified under seven different categories. Criterions of the each factor were also developed, and weight of each factor was assigned by applying the Analytical Hierarchy Process(AHP). Finally, based on the Monte Carlo simulation, the feasibility analysis model was established, providing probability distribution of project's grade. The model was applied to 12 housing projects to verify its reliability, and found that the model properly filtered projects that are unlikely to be profitable, indicating reasonable reliability of the model. The model can be a useful tool for contractors, especially with less experience in analyzing project development feasibility.

As the government has enforced recently the policies on the distribution of the housing, the construction cost of multi-family housing projects has increasingly become very sensitive and political issue. However, it is difficult to predict the construction cost in planning and design phase of the project because the Bill of Quantity of the multi-family housing projects was composed of breakdown structure based on each work package. To predict the construction cost in planning and design phase for multi-family housing projects in more effective and reasonable way, this study developed the cost breakdown structure based on spaces using Delphi method. The Cost Breakdown Structure (CBS) based on spaces for multi-family housing projects basically consists of three parts: (i) Building part; (ii) Non-building part; and (iii) Additional part. The characteristics of spaces in multi-family housing projects are fully taken into consideration. Then these three parts were subdivided into work packages in terms of work tasks. Additionally, the usefulness and effectiveness of Space CBS in this paper were validated by analyzing the BOQs of several collected sample projects and matching with Space CBS afterwards.
