To investigate opportunities for wood frame housing and to activate wood frame house construction, trends of construction activities. preference about housing, and building codes related to wood frame housing were discussed. And two models of wood frame house were developed and construction cost was analyzed to compare with comparative masonry houses. The results obtained were as follows: 1. While 77.8% of people prefer single-family houses, majority of people(74.9%), ironically, possess multi-family houses such as apartments Wood work cost was ratio of 4% of total building cost. while wood material cost accounted merely for 11 % out of total building material cost. 2. Building code was not major barrier to residential house at height under 13m. The building code regulated major structural member and family boder wall of multi-family house to be built with fire retardant material. 3. The proper wood frame house was analyzed of town house or villa type locating in suburban of big city with hot ondol system for the upper middle class. 4 There was no difference in construction cost between western style wood frame house and comparable masonry house, but construction cost for Korean style wood frame house is 27% higher than that of comparable masonry house. It was necessary to reduce materials and cost down by prefabrication technique for both style of wood frame house.

At the Korea Land and Housing Corporation(LH), concretes with high design strength of 50 MPa and 80 MPa that are composed only of ordinary Portland cement, blast furnace slag, and fly ash are developed. To determine whether the developed high strength concretes have the same properties when they are produced in batch plant(B/P) condition in the ready mixed concrete plant, and as existing high strength concretes, field tests are performed and material properties are evaluated. To investigate the material properties of the high strength concretes before and after pumping, compressive strength, flowability, air content, hydration temperature, pumping and compactability are evaluated. In field tests, before and after pumping, flowability satisfied the relevant criteria. In terms of air content, while it was slightly decreased after pumping, it satisfied the requirements. Hydration temperature criteria were satisfied, and compactability was excellent as well. The study found that the developed ternary high strength concretes have the same properties as existing high strength concretes. They can also be useful for the construction of high-rise buildings, as they are economical.

The purpose of this study is to predict remodeling timing of Permanent Rental Housing through historic data and cash flow analysis. For this aim, the study has estimated cash flow of Permanent Rental Housing considering initial construction costs, government supporting fund, rental incomes and maintenance expenses. Based on the expected cash flow analysis, reasonable remodeling timing is predicted for Permanent Rental Housing. The results of this study are as follows: (1) it is analyzed that building a8e of about 27 years is the best time for remodeling because cumulative surplus amounts reach maximum level, (2) it is required that remodeling should be made before 34 years of age roughly because cumulative surplus amounts change into minus from this time.

The objective of this paper is to suggest structural design for the long-life housing apartment complex to save the construction cost. The key is to use unavailable underground space due to bearing walls or bad configuration of columns in apartments as the parking space. Therefore, the structural plan of apartment buildings considering the parking section in the underground should be designed. After analytical resutls of three cases, it is significant effect in saving construction cost.

Low-income housing policies in South Korea have been pursued mostly by providing public rental housing for less privileged social groups. In contrast to this notion of housing, this article argues for housing ownership by low-income families. Two examples of this ownership policy are found in Chile. Incremental housing involves an open-ended housing platform, which requires home-dwellers to complete the construction process themselves. This article aims to examine structural, spatial and formal characteristics of the incremental housing projects. Taking the perspective of the home-dweller during the incremental construction process, we evaluate the houses before and after customization. Thus, we use data from field-work conducted for seven months in the Santiago Metropolitan Area of Chile. Using qualitative methods such as observation, semi-structured interviews, and surveys we focus on the Elemental Lo Espejo incremental housing project and then compare it with the Las Higuera housing project. The latter is representative of the incremental houses delivered by the Chilean government. In comparing these two projects, we aim to articulate the lessons of incremental housing with the intention of suggesting possible future developments for a wider-reaching incremental housing program.

Despite the many advantages of modular housing, low preference for modular housing for consumers who are familiar with RC structure leads to high construction cost of modular housing. The cost of modular buildings is about 130% of that of RC structures, so it is urgent to secure economical efficiency of modular buildings. Therefore, in this study, after calculating the savings amount of modular housing by type of construction work, economic analysis was conducted from a long - term perspective. In order to carry out the research, the authors compiled and analyzed the material cost, labor cost, and expenses incurred by each type of work by reclassifying the statement of the modular housing into the factory production and the site installation. After that, Pareto diagrams were created to find a core work that is included in the cost ratio of about 80%, and selected it as a cost reduction subject. Based on the assumption that the market size of domestic modular housing is similar to the level of modular advanced countries such as Japan and European countries, six cost reduction methods were set up that reflects the characteristics of the modular construction method and used for the expert interviews. Cost saving potentials in percentage from the interview were converted to the amount of savings that can be achieved by each type of method when applying the method. Finally, the findings of the study are expected to suggest long-term directions for technical development for modular construction and cost savings.

Since 1939, Bupeyong was rapidly urbanized and industrialized for the purpose of constructing military logistics base of the empire of Japan. Based on Kyungin urban planning of 1940 and industrial land development plan of Kyeonggido, many military factories and arsenal were constructed, and great amount of housing were also built for their workers from 1939 to 1944. Although the initial urban planning was unfinished, urban change from rural area to military industrial city in the late Japanese colonial era, made identity of city of Bupyeong. Workers houses which built during five years vary in different size and type, and somewhat reflects discussions about housing attempts to solve the housing shortage. This study aims to analyze architectural characteristics of workers housing related with discussions of housing, and to evaluate its value as an industrial heritage which constitute the urban landscape of the industrial city of Bupyeong. Workers houses in Bupyeong were constructed by military factories, construction company, and Chosun housing administration, with land readjustment planning. As the war became serious, workers housing became smaller and simpler. Construction of workers housing was essential part of modern military industrial city, bupyeong, and many of workers housing are still remained whereas most of factories were demolished, thus workers housing of bupyeong has significant meaning as industrial heritage of Bupyeong.
