Understanding the Floor Area Ratio (FAR) is essential for optimizing construction projects. FAR determines the allowable building area relative to plot size, influencing project scale and density. In Delhi, FAR varies by zone, affecting design and compliance. Construction costs per square foot in Delhi depend on factors like material quality and design complexity, ranging from Rs 1,500 to over Rs 7,000. Higher FAR can increase construction costs due to additional materials and labor. Balancing FAR with budget constraints is crucial for achieving optimal design and cost efficiency.
