Abstract This paper depicts a sustainable approach for the safe and cost-effective construction and design of foundations at Devannapet village, Hasanparthy Mandal of Warangal, Telangana State, India. Owing to the uneven topography of the site, the residential building was proposed to be constructed at a relatively higher slope compared to the road level. The uneven distribution of the soil stratum necessitated the adoption of novel and sustainable site-specific foundation technique. To meet the sustainability criteria, the excessive material obtained from the site during the leveling was utilized as construction material (filling, drainage, and as a component in concrete mix design) and in the design of stone masonry earth retaining structure at the downstream side. The engineering philosophy behind designing such a foundation has been discussed in detail in this paper relying on cost–benefit analysis for various components of the foundation. The seepage and drainage problems at the foundation level have been discussed. The details of reinforcements, stability checks, and the resultant design have been discussed in detail in this manuscript. The sustainable method employed in this article will assist the practicing engineers in designing cost-effective foundations for residential buildings when similar terrains are encountered.

Introduction India is rapidly urbanizing. Urban planning and building constructions in hilly regions require thorough landscape architecture, economic, and ecological benefits, at both national and local levels involving sustainable construction practices. This planning should consider improving the environmental quality relying on locally available suitable materials, liabilities associated with site selection [1]. Hilly regions, though appealing to construct a structure at, have wide variations in geomorphology, climate, altitude, and materials resources. These variations in geomorphology manifest in the formation of poor soils along steep slopes which can impact the structure(s) leading to potential problems associated with slope instability such as landslides, uneven settlements of foundations followed by cracked walls [2–6]. Accordingly planning and design of buildings along with the right foundations in hilly regions is an arduous task. The foundations in hilly regio
