A building plan is the detailed architectural and engineering drawing that illustrates how a structure will be built. It shows dimensions, layout, and structural elements, guiding every professional involved—from architects and engineers to contractors and inspectors. In Nigeria, a building plan is a legal requirement before construction can begin.
This document helps ensure compliance with zoning regulations, safety codes, and environmental standards. It also acts as a roadmap for material estimates, cost control, and scheduling. A well-prepared plan reduces errors, prevents costly redesigns, and streamlines the approval process with local planning authorities.
Without a proper building plan, projects risk regulatory delays, safety hazards, and budget overruns. A professionally prepared plan also protects property owners legally by documenting all specifications.
