Land and property rights problems will remain unchanged if a policy and update of property systems and land registration are not prepared. Only a small percentage (an estimated 10 to 20 per cent) of Yemen’s land is registered. Eighty to ninety per cent of land transactions occur through basira or informal documentation. In order to solve land problems, the government must prepare a land policy and establish a national real estate registry, taking into account current and future changes and challenges. Over the years, secure land tenure and property rights have taken on greater historical and cultural significance for Yemenis. Despite this importance, it is estimated that nearly 85 per cent of court disputes in the Republic of Yemen today are land-related and up to 90 per cent of land ownership remains informal.

Modern construction depends principally on imported building materials, which are very expensive. In most cases, a cost reduction is attained, by lowering the construction quality, as a result leading to non-attractive and less durable and more costly buildings. A survey was conducted locally in this paper, to investigate the construction costs of structural and finishing elements; the outcome showed that the cost of structural elements is the major contributor to high construction costs. Based on this outcome, a Delphi method is performed, to list experts' most crucial recommendations that are needed to enhance the situation in Yemen.

A questionnaire survey has been used as the tools to carry out this study. The questionnaire survey consisted of 32 factors which were grouped into five major categories named; land factors, materials used factors, construction methods used factors, finishing works factors and external factors. The level of importance of the categories was measured and ranked the relative importance weights. This study found that land cost factor, cement cost factor and steel cost factor are the most important factors influencing housing cost in Sana'a. Based on the analysis of the ranking and intensity of a housing cost factors, this paper suggests possible improvements that could be made in order to decrease the housing cost.

Thus, this research looks over building materials and labour construction technologies used on the local housing construction projects by verifying the percentage of construction expenditure consumed by the main construction components (Materials, Labour and Overhead and Profit), along with the implemented construction technologies. The paper conducts a survey to acquire the cost distribution of the construction main components. The outcomes of the survey were discussed; the discussion was supported by literature on similar issues from some countries. The outcomes confirmed the relatively limited percentage in labour cost and profit, and the elevated percentage of construction materials cost, which are because of the excessive and inappropriate use of materials. What’s more, established that the exces...

Unprecedented rapid urban growth coupled with lack of infrastructure has led to the problem of housing shortage for the low-income group in Sana''a, the capital city of Yemen. Consequently, informal housing patterns are observed clearly in some sectors of the city. The low-income group has built this kind of housing urgently and in some cases immediately as the final and only solution, yielding serious implications on the quality and safety of the houses. The overriding objective of this study was to identify the significant factors, which have influenced the construction cost of housing in Sana''a to resolve the housing shortage for the low- income group. Specific objectives have included determining the factors causing housing shortage for low-income group in Sana''a; justifying the significant factors influencing the cost of low-cost housing; and recommending to relevant authorities in Yemen to improve housing policies to mitigate the housing shortage in Sana''a.
