Concept Design & Cost Estimate

I am planning a small commercial building in Visakhapatnam, Andhra Pradesh, with a built-up area of less than 3,000 sq. ft. **Requirements:** 1. **Cellar:** Underground cellar. 2. **Ground Floor:** Provision for 12–14 shops. 3. Initially, I want only a **bare-shell construction** with open space, shutters, and open walls. Shop partitions can be added later if required. 4. **Lifts:** Provide space/provision for two lifts on both sides for future installation. 5. **Future Expansion:** Initially, I will construct only the cellar and ground floor, but the structural design and foundation should be suitable for **up to 5 floors** in the future. 6. **Plot Surroundings:** * North: 33 ft road * West: 60 ft road * South: 60 ft road * East: Existing house 7. **Construction:** Simple and economical commercial construction. Please check the uploaded file and provide: * A rough preliminary drawing/layout. * Approximate construction cost for the cellar and ground floor. * Rough design/engineering cost. * Structural provisions required for future construction up to 5 floors. The present requirement is only for a **rough design and approximate cost estimate**.
