Abstract

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.

2017년 현재 848만 세대가 공동주택에 거주하고 있고, 15년 이상 노후공동주택은 55.87%이다. 공동주택 리모델링 허용연한 기준은 15년 이상이므로 앞으로 공동주택 리모델링 시장은 계속해서 증가할 것이다. 리모델링 사업의 성공을 위해서 사업성 분석은 중요하지만 기존 신축 및 재건축의 사업성 분석방법이 리모델링 사업성 분석에 사용되고 있다. 그러므로 건축법에 의한 세대수 증가 없는 맞춤형 리모델링 사업성 분석에 관한 연구가 필요한 실정이다. 본고에서는 공동주택의 지가(地價)와 건물가의 형성에 영향을 미치는 요인을 도출하여 맞춤형 리모델링 사업의 사업성 분석 방법론을 개발하는 것을 목적으로 공동주택의 가격형성 개념에 따라 공시지가, 공시가격, 표준지가, 기준가격에 영향을 주는 요인을 사용한 노후 공동주택 맞춤형 리모델링 사업성 분석 방법을 제시하였고, 향후 개발된 계단가격법은 리모델링 사업진행단계에서 리모델링 주택조합 설립인가 후 시공자 선정 단계에서 활용 가능하다.
