Dwelling Affordability from Theory to Practice: The Use of Earth as Indigenous Building Material for Sustainable Development Amidst Post Covid-19 Situation in Nigeria (Published)
Driven by urbanization and demographic growth in Nigeria, the estimated cost for low cost dwelling unit is very expensive, because of high cost of conventional building material. Indigenous building materials abound in our various locations and communities in our nation, in the olden days dwelling place were never an issue as man could make or create a dwelling place for himself and his family with available indigenous resources. He uses local materials such as earth, timber, bamboo, stone, thatch, bush rope, etc with one or two assistant and able to put together a dwelling to accommodate his activities. The paper examined earth as indigenous building materials and assessing local building cultures with earth for resilience and sustainable development for dwelling affordability in Nigeria. Also, it generates a practical guide for community-based assessment of earth material fortification without compromising the durability. The sustainability solution of earth as building material were discussed which include local employment opportunity for socio economic development among others. The paper then concludes on some sustainability strategies known with the earth over the year as productive and effective building material.#

The Sustainability Solution of Earth as Buildings material: Case of Gbongan Rural communities in Osun State south west Nigeria (Published)
The sustainability of earth as building material cannot be overemphasised with proven superior performance at the specified criteria. This research addresses the analysis of the sustainability criteria present in a sample of 120 cases of traditional earth building at Gbongan rural area in Osun state Nigeria, as locally produced and sourced material, reduced transport cost and environmental impact among others. The focus group of professional especially architect and builders were organized to coordinate the study process, ensuring adequate evaluations of issues that can facilitate sustainability of earth as a building material. Their recommendations are evaluated and classified according to physical attributes of earth as sustainable building material: twelve prevailing factors facilitating sustainability of earth as building material were identified. The sustainability solution of earth as building material were discussed which include local employment opportunity for socio economic development. The paper then concludes on some sustainability strategies known with the earth over the year as productive and effective building material.
The sustainable Impact of Alternative Construction Process on shelter provision: The Case of low-income group in Osogbo Osun state amidst post covid-19 pandemic in Nigeria (Published)
This paper examined the impacts of alternative construction process on building provision in Osogbo Osun state Nigeria, it is to assess various alternative construction process in comparison with the conventional methods whether which of the two has led to increased housing provision for low income groups. The study addresses the economic effectiveness attained, during the alternative construction process this was compared and reviewed in detail. The focus group of professional especially architect and builders were organized to coordinate the study process. This research addresses the sustainability impact of earth as building material at Osogbo in Osun state Nigeria, the impacts were analyzed, presented, interpreted and discussed mainly on the comparison of various conventional materials such as, cement and steel due to high manufacturing cost. The paper reveals the prevailing factors that facilitate sustainability impact of earth as building material, which include Low Energy required in the manufacturing process among others. The paper then concludes on locally produced, sourced and unprocessed material as a means of sustainable impact within the reach of low-income group.
Inherent Defects Associated With Original Construction Methods and Materials Used For Earth Buildings in Nigeria: Case of Gbongan Rural Communities in Osun State (Published)
The durability and longevity of an earth wall is dependent as much upon the raw materials originally employed and methods of which the traditional building was constructed. This research addresses the analysis of the pathologies present in a sample of 120 cases of traditional earth building at Gbongan rural area in Osun State. The defects identified are related with construction methods in which they are detected. The soil particle distribution of earthen material was analysed, soil properties which make soil a suitable construction material are discussed. The paper then concludes on some earth property tests such as composition, consistency, dry shrinkage, coefficient of expansion that enhance durability of earthen structure.
