PurposeFunding infrastructural facilities of higher institutions, especially in some developing nations such as Nigeria, that is under-funded, is a challenge in the current era. Private organisations participation in infrastructure development via a proposed expanded corporate social responsibility (ECSR) may enhance infrastructural facilities provision. There is a paucity of literature regarding ECSR, a form of infrastructure tax relief providing infrastructural facilities for higher institutions. Therefore, the study investigated the role of private organisations via a proposed ECSR in the provision of infrastructure and proffer ways to enhance higher institutions' infrastructure development delivery in Nigeria.Design/methodology/approachThe study data were collated via face-to-face interviews and observation of existing buildings. From the six geo-political zones, two higher institutions each were selected for a good representation across Nigeria. Saturation was achieved with 26 participants interviewed. The emerged three main themes were analysed via thematic analysis.FindingsFindings show inadequate infrastructure development in Nigerian higher institutions. Lack of policy and institutional framework, lax governance, level of transparency, and corruption, emerged as the key issues that may hinder private organisations from participating in public higher institutions infrastructure development delivery in Nigeria via ECSR. Others are lack of autonomy, inadequate planning, high level of impunity, political affiliation, poor management, and access to funding. The study proffers some recommendations based on these findings.Research limitations/implicationsThis research is restricted to the role of private organisations via ECSR in infrastructure development (buildings) in Nigeria's public higher institutions. Future study is needed to validate the proposed ECSR framework in developing countries for the provision of buildings for higher institutions in their host communities.Practical implicationsThe paper will advance the philosophy of corporate social responsibility to the provision of building facilities in host communities' higher institutions by private companies through tax relief and supported by a proposed Presidential Executive Order.Originality/valueThe proposed ECSR framework can be used to improve building facilities in Nigeria's higher institutions. This may assist and stir up policymakers to explore the proposed model and back up with an established policy such as infrastructure tax relief (ITR) for implementation.
