Abstract

Urban housing development requires proper financial planning and cost control to ensure affordability, sustainability, and efficient utilization of limited land resources. In rapidly developing urban regions, residential construction on small plots such as 1250 sq. ft. requires optimized planning approaches that balance comfort, functionality, and economy. Cost estimation plays a major role in determining the feasibility of residential projects before construction begins. This research presents comparative cost estimation and planning analysis of two residential building options proposed for the same 1,250 sq. ft. site. plot. Option A represents a Premium Residential Building with high-standard planning, larger room dimensions, premium finishes, and enhanced service provisions. Option B represents an Economical Residential Building designed with compact room layouts, essential facilities, and cost-effective construction techniques. The study includes quantity take-off, rate analysis, Bill of Quantities (BOQ), cost distribution analysis, and comparative financial evaluation using prevailing market rates of 2025 and CPWD Schedule of Rates 2024–25. Detailed estimation reveals that the total construction cost of Option A is ₹39,60,000, whereas Option B costs ₹25,74,000. The overall cost difference between the two alternatives is ₹13.86 Lakhs. The results demonstrate that efficient planning, optimized built-up area, economical finishes, and proper structural design can substantially reduce overall construction cost while maintaining structural safety and functional efficiency. This study provides valuable insights for homeowners, engineers, planners, and middle-income families in selecting the most economically feasible residential solution.
