Thinking resiliency in terms of housing features for post disaster housing reconstruction (PDHR) is a paramount initiative after a disaster. Therefore, the aim of this research is to ascertain the demands of the disaster victims and propose a wind-resistant, resilient housing prototype that would be affordable. Based on a three-month survey of the region severely damaged by Cyclone SIDR in Bangladesh, this research argues that PDHR’s planning features are significantly short of the victims’ choice, need, and demand, forcing them to quickly modify or transform the reconstructed houses. Based on the survey, a prototype covering an area of 37.21 sq. m (400 sq. ft) with a hybrid construction technique and a cost model are proposed that will be a resilient solution against cyclones and other natural hazards. Additionally, the proposed house was modeled using finite elements, and its findings are within the International Building Code’s allowable limits. In conclusion, this paper proposes some guidelines to strengthen Bangladesh National Building Code (BNBC) that would enable to build a resilient housing society in the disaster-prone areas.
Post occupancy evaluation of housing reconstruction after a disaster is imperative for every nation that pushes ahead the idea of resilient housing, which is obligatory for the social, cultural, and economic growth of a society or a country. Cyclone SIDR is the most dreadful of all catastrophes that have struck Bangladesh and aftermath of this catastrophe, a number of donor organizations stepped up to help victims by providing housing solutions. The aim of this study is to effectiveness analysis of the housing reconstruction programs from planning and construction standpoints with a post occupancy framework. Based on three months of detailed field survey at the mostly devastated location of cyclone SIDR, Southkhali Union (small rural area) of Sarankhola Upazila (sub-district) of Bagerhat District, this research infers that the donor organizations didn’t pay much attention in terms of choice, need and decision-making role to provide reconstructed houses for the target beneficiaries. The study found that about 78% of the reconstructed houses hold dissatisfaction of the beneficiaries. As a result, people prompt to transform or modify 54% of the ‘Donor Driven’ houses according to their choice and need soon after completion of the project. Another 16% donor driven house remained abandoned and rest 8% demolished. On the other hand, owner driven houses are functionally perfect, affordable, use locally available natural materials with resilient planning and construction features which reduces disaster vulnerability and sustains for long time in comparison with donor driven houses.
