This article deals the investigations how to solve the social deficiencies of deteriorate apartments, which is a half cycle of a building and it goes slum clearance and redevelopment. And this proposes an active remodeling and design strategy, management, and housing policies for extending the usage of the resource. Most of apartment housing in Korea is built by the panel wall and slab structure system fur economic price. To remake is possible, even though not designed in flexibility and variation. The remodeling strategies are dwelling unification, transformation of two units to one or three units, addition of a room, changing into commercial and community required spaces, and reshaping of a envelop and facade by addition of a dwelling or dwellings, roof floors, change of materials and colors, and so on. And, all activities in structural aspect are proposed removal in upper part and addition in lower part of an apartment housing. Active remodeling cost a great deal compare to new construction, so any remodeling activities should be based on a minimal interfere and budgets to enhancing the quality in existing building. The final aim of an active remodeling is to enhance the quality in economic values, and to keep original state and to put on the new one in a small part. To promote the active and careful management and rehabilitation, it is necessary to give the positive incentive in terms of architectural law, bank loan, and any redevelopment project should get the remodeling record in national resources.

The number of apartments has been increased, and it is time to activate the remodeling or reconstruction. Recently remodeling has been preferred to reconstruction, because reconstruction might cause many problems. At this point of time, remodeling could save resources, preserve environment, and expand the construction market places. However, most research for remodeling is aimed to improve the financial value, and structural effects being caused by floor plan modification has not been done yet quantitatively. Remodeling naturally brings to floor plan modification, and it can cause serious problems of structural side. So we made apartments an object of study, then analyzed stress variation of structural elements according to the removal of shear wall, supposing the floor plan modification. For this purpose, we selected a sample of universal apartment floor plan and extracted floor plan modification factors. Then we applied the factors to sample floor plan and organized the results of stress variation of structural elements. As results, walls are most harmful when the independent walls are removed, and in case of slabs, it is most critical when continuous walls are removed.

Recently, remodeling of the reinforced concrete apartment became hot issue of the housing policy in Korea. In Korea, the seismic design regulation has been revised since it was established in 1988 first, in order to minimize the economic losses. It has studied that the apartments that built in 1980's and their new remodeling for seismic performance. Also lateral displacement of remodeling analysis about variation of shear-wall for apartment on the architetural remodeling. Position change by wall quantity is state that study about efficient guide line about apartment wall quantity changed at remodeling because it is factor that can influence on motion of whole building is insufficient.

The purpose of this study was to provide guidelines for the remodeling understanding the needs of apartment housing residents. In order to achieve our goal, questionnaire surveys were used. We sampled the questionnaire surveys of the households in Seoul whose apartments had been more than ten years and recently remodeled. The materials collected by a questionnaire survey were analyzed by examining the frequency, percentage on the SPSS/PC+ Statistics package. The results of the questionnaire survey were as follows: (1) Residents tend to demand better environment than an economics benefits from remodeling. (2) Residents wanted to have organized the remodeling group that can help to solve the problems concerning profit and loss among residents. (3) Residents wanted to be supported by government, expand loans from monetary organizations, and have a reserve fund for the remodeling.

The purpose of this study is to provide the feasibility of apartment remodeling types in DaeJeon City. This study was conducted by survey for the residents' perceptions of the apartment remodeling. In addition, this study estimated the cost according to remodeling types by comparing it with that other apartments in DaeJeon City. By doing so, this study evaluated the feasibility of remodeling. The results of this study are as follows: 1. Not only the level of the residents' perception but also the intention of apartment remodeling was high. 2. The cost of remodeling was similar to that of residents had answered at questionaire. Thus, the remodeling cost proven to be very reasonable. 3. The cost of horizontally expanding remodeling type was cheaper than that of moving within the same apartment complex or into the new apartment. The cost of others (duplex, expansion or reduction of household) are cheaper that of moving. But one of the difficulties in carrying out these types lies in the fact that the remodeling should be performed in the apartment complex or building. Accordingly, this study proposes that horizontally expanding remodeling type is more feasible in DaeJeon City.

Alongside the increasingly larger domestic construction projects is the gradual rise in construction waste. Consequently, serious environmental problems emerge. The increase in demand for housing remodeling due mainly to the increase in national income and improvement of quality of life is the main reason for the increase in construction waste. This study was conducted as the basic study for the prevention and reduction of construction waste generated by apartment remodeling; it aimed at identifying the remodeling items and reasons. Toward this end, this study targeted apartments at least 15 years old and conducted a questionnaire survey to determine the remodeled sections and remodeling reasons. As a result of the questionnaire survey, the bathroom, floor finishing, and kitchen furniture recorded the highest ratios in remodeling. Old materials, aesthetic motivation, and pleasant living space composition were cited as the major remodeling reasons. This study is significant as a basic study for generating environmental and economic profits through systematic waste management. Further studies should develop guidelines suitable for construction waste reduction and recycling in line with the construction and demolition phases in case of remodeling.

The necessity of remodeling performance grading system is getting increased for the systematic management of existing housing stock, providing the resident's right to know and promoting the remodeling projects. A quantitative and objective evaluation method that has reflected the characteristics of remodeling must be developed because there is an aspect of having difficulty of assessment by an ordinary person as remodeling performance contains specialized details while the difficulty of applying the criteria of new buildings in terms of assessment items, criteria and methods. Accordingly, this study sets the goal as setting up the development objectives of performance grading system that has considered the remodeling characteristics. This study has analyzed the various assessment systems related to the domestic apartments as well as setting up the organization system of the remodeling performance grading system, perspectives of performance assessment and scope of assessment through literature, etc. It has also established the principles for setting up the assessment items of remodeling performance grade to present the directions for setting up assessment items and criteria.

Currently, reconstruction and remodeling are conducted to improve the performance of aged housing. Recently reconstruction has caused many problems such as wastes generation, wasting resources and real estate speculation, remodeling is drawing attention. Accordingly, remodeling business for aged housings gradually increasing, but the use of scheduling method not considering characteristics of remodeling deters construction in some construction types. Especially, in case of dismantling construction, the dismantling is delayed since the scheduling method not considering characteristics of remodeling is used. In case of remodeling, dismantling construction is ahead of other processes, if the dismantling construction is delayed, whole construction will be delayed and if speedy construction is conducted, the costs for remodeling will increase. Furthermore, existing remodeling for aged housing has been for rahmen(crossbeam and pillar) structure apartments, but since most apartments to be remodeled are wall-slab structure where dismantling takes a lot of weight, it is highly possible the dismantling construction is delayed. Thus, this paper is to establish scheduling method for the dismantling construction reflecting characteristic of remodeling to prevent delay of dismantling construction for remodeling of aged housing with wall-slab structure.

Apartments have been the most prevalent type of housing in Korea for the past few decades. During those times, apartments have emerged as one of the most attractive real estate properties in Korea, with the still growing population living in them. Now that over twenty years have passed since the 1970s and 1980s when apartment construction started booming, building stocks are increasing that need refurbishment. In this concern, apartment extension has raised public interest for the past few years, as the remodeling of them has mainly been considered in terms of increasing asset value in Korea. It comes through in our study that these extension types are examined by such items as building core types, number of rooms and front and rear bays in unit, and other design features related to extension techniques. The objective of this study is to suggest a way to produce the best quality possible of unit plan through extension.

This study aims to seek a proper policy direction in response to the demand for apartment remodeling. As the research methods, we diagnosed the current status of the remodeling policy and analyzed the demand for apartment remodeling nationwide. According to the result of analysis, we suggested the fundamental direction and tasks for remodeling policies to be pursued at the government level. The results of the study are summarized as follows. First, the result of analysis showed that the demand for environmental improvement(performance improvement) remodeling project was much higher than other types of remodeling projects. The percentage of unit increased-type remodeling that can secure business feasibility is about 10% and only 30% when it comes to reducing project costs. The remaining 70-90% need to be promoted in environmental improvement remodeling projects which dependent on the residents' payment. Second, in order to prepare a policy action plan in response to the demand for apartment remodeling, it is necessary to set up clear policy goals and strategies for apartment remodeling in advance at the national level. Along with proactive goals and strategies, graded policy support should be accompanied per type of remodeling and business demand. We also suggest to simplify administrative procedures and support the R&D research to develop technologies. It would help to utilize the unit increased-type remodeling. On the other hand, for utilizing the environmental improvement remodeling which takes up a relatively high proportion, the policy should take care of as follows: offering housing performance information, rationalizing long term repair reserve, fostering small companies and experts. Finally, apartment management system should be advanced from the perspectives of managing old apartments and institutional foundations such as new construction and customized regulations for differentiated remodeling should be accompanied.
