Thus, this study aims to explore and assess design strategies to achieve environmental sustainability in telecommunications buildings within Nigeria. Employing a case study approach, six cases were examined, consisting of two international and one local telecommunication office buildings, along with three other office buildings each representing a key aspect of the design development. These case studies were evaluated based on design strategies identified from empirical studies in the literature review, including sustainable site design, water conservation and quality, energy and environment, and conservation of materials and resources. The findings revealed varying degrees of implementation of these strategies in the selected case studies. Drawing insights from the case study analysis, the research proposes an environmentally sustainable head office building for MTNng in Falomo, Lagos. By incorporating the sustainable design strategies learned from the case studies, the proposed design aims to mitigate the environmental impact. Ultimately, the study's findings and recommendations offer a roadmap for architects, engineers, and stakeholders involved in designing and constructing telecommunications buildings in Nigeria. Implementing these guidelines can effectively reduce the industry's carbon footprint, conserve energy resources, and actively contribute to the overarching goal of sustainable development. Ultimately, the research endeavour seeks to foster an environmentally conscious and responsible telecommunications sector in Nigeria.
