As of 2017, there are 848 million households living in apartment and 55.87% of Aged apartments over 15 years old. The allowable standard for remodeling the apartment is more than 15 years and the market for remodeling the apartment will continue to increase. For the success of the remodeling project feasibility analysis is important but the existing feasibility analysis of new construction and reconstruction is being used for remodeling feasibility analysis. Therefore, it is necessary to study the feasibility analysis of customized remodeling without increasing the number of households according to the building law. Purpose of this paper is to develop a feasibility analysis methodology for customized remodeling projects by deriving the factors affecting the formation of land prices and building prices in apartment. According to the concept of price formation of the apartment, the analysis method of the customized remodeling of the old apartment using the factors affecting the Land Price Indexes, Officially Assessed Individual Land Price, House Price Indexes, and Officially Assessed Individual House Price was suggested. The Stair Price Algorithm developed in this research can be utilized at the stage of selecting remodeling contractors after the remodeling housing association is established.

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.

Remodeling of multi-family house (MFH) has emerged as a major issue in the construction industry. Many decision-makers are struggling to determine whether to conduct a remodeling because of insufficient information including standard or method for projecting the price of their facilities after remodeling works. In this context, this research has conducted for analyzing how the price of the MFH is shifted by remodeling works. To achieve this research goal, (i) fourteen MFH remodeling cases were collected and (ii) price variation for the collected cases was analyzed in order to figure out how remodeling work affects the price of MFH cases. Finally, this research suggested the factors determining price of the MFH, wherein remodeling work has been conducted. From the results of this research, it is expected that the decision-makers can understand what is the crucial factors for determining the price of their MFH when they plans remodeling, and further this research can be a corner stone for developing a model for predicting the price of MFH if remodeling would be performed.

Recently, apartment-remodeling project is booming since various reconstruction controls are tightened. However, the project has difficulties because management systems used for apartment-remodeling projects are not available. Identifying and analyzing risk factors that are required for risk management, this paper suggests the risk level through paired comparison performed by AHP method and probability assessment for risk level analysis. It is expected that this research will be utilized to minimize the risk of apartment remodeling project and for basic materials to perform the project and helpful to change newly build-oriented construction into sustainable industries. Hereafter using the risk factor analysis data of this paper for this research project, risk management model is considered to be constructed.

After the global financial crisis, domestic construction industry has gone through a rapid recession. This resulted in gradual market shift towards architectural remodeling. Architectural remodeling not only improves residential environment but it has many advantages such as increase of each unit's exclusive area, free space within the horizontal or extension of an annex building, and increase number of household through splitting the household of bigger pyeong, etc. However, in case of the Korean market for apartment remodeling, due to various regulations and problem with business promotion procedures, majority of business is slow despite the figure that remodeling volume is not that small. Also, feasibility study which decides to push ahead public house remodeling business will have a flaw using net present value's law; it has a flaw of not considering properties of each phase of remodeling business and future's uncertainty. Hence, this research will improve the problem of traditional value assessment method of net present value's law. It will also consider one of the real options such as binomial model in order to supplement NPV which is used in current feasibility study. This research was based on real successful cases of public house remodeling and it was possible for feasibility study which was more realistic and valid. This research provided foundation for development of Korean public house remodeling market. There is high anticipation of increasing the validity by improving the problems of current feasibility study and economic efficiency assessment.

Markets for the apartment remodeling projects will be a major portion of the construction industry in near future. However, only partial remodeling works in the apartment were done so far. This situation caused bad impact to expand the remodeling markets and less profits of the remodeling projects. In order to solve this problem, many other researches were done previously to Improve profits of the apartment remodeling projects. However, the results are too theoretical to implement them and Improve profits. In this research, profitability influence factors that are possible to improve effect of the remodeling works are selected and analyzed through several studies. Then, correlation analysis is performed between the improvement level in the remodeling projects and the numerical profitability based on actual cases. The result clearly shows that some improved remodeling items are strongly related to the profit.
