The continuous increase in the urban population worldwide has exacerbated the intensity of urban land use conversion and spatial consumption. This motivation for a better urban space led to the evolution of sustainable urban development, urban liveability, environmental awareness, inclusivity, and urban governance. Therefore, this research aimed to establish the intricate links between sustainable urban development, urban liveability, and inclusive physical development in selected cities in North-Central Nigeria. The theories examined were Citizen Participation, Dependency, Modernisation, and Infrastructure. The selected cities were Lokoja, Lafia, and Minna, all incidentally equidistant to Abuja, the Federal Capital City of Nigeria. This research employed a mixed-methods approach by collecting both qualitative and quantitative data. These data sets ranged from satellite imageries used for the spatio-temporal analysis and urban growth simulation through ArcGIS, Q-GIS, and the Artificial Neural Network. The extent of infrastructure provision and their methods were appraised using the instrumentality of the nearest neighbour analysis and the partial least square analysis using the SmartPLS. The research also appraised the stakeholders’ perceptions and methods of infrastructure provision through a word cloud analysis using NVivo analytics. In analysing the provision and condition of the infrastructure in North-Central Nigeria, educational infrastructure was found to be inadequate and poorly maintained; inadequate budgetary allocations exacerbated the problem of urban infrastructure overuse; illegal developments often overtook sites reserved for infrastructure; and funding, vandalism, and project continuity were cited as critical factors. The infrastructure that suffered the highest maintenance neglect was the urban water supply, education infrastructure, and the health care facilities. Political motivation and the population played the most significant roles in the region's urban infrastructure or project development. The triad of consumption, access, and equity was used to evaluate Hangwurian City Development's (HCD) proposed sustainable urban infrastructure development plan. Convergent validity was strong in the region, where the AVE was significant at 0.56 or more. A compact development model was found to be a valuable indicator for qualifying the cities. It was found that the challenge of planning regulation and siting of infrastructure could be addressed effectively, however, the public and private sector promoters of projects had to stick to their parts of the bargain. Cities across North-Central Nigeria had to undertake citizen-focused infrastructure planning and development. Therefore, the researcher concluded that city development and urban growth could be moderated through the instrumentality of adequate infrastructure provision and planning to prioritise the needs and desires of residents. This is achievable by adopting the Hangwurian City Development Model, which helps to promote cities without ills.
