In a recent move to promote urban development, the Maharashtra government has amended regulations governing open spaces for commercial buildings with glass facades. Responding to a request from CREDAI-MCHI, a prominent real estate advocacy group, the state has adopted the premise that glass structures offer sufficient artificial light and mechanical ventilation. This pivotal change allows developers to reduce setback regulations and decrease the distances between buildings, thereby facilitating denser construction in Mumbai’s urban landscape.
Proponents of this policy shift argue that it is a crucial step towards stimulating economic growth. By easing the compliance burden associated with stringent open space norms, particularly under the Development Control Promotion and Regulations (DCPR)-2034 framework, the state aims to optimise floor space index (FSI) allowances of up to 5 for commercial structures. Industry representatives contend that the previous regulations imposed significant constraints on maximising FSI due to the high costs linked with maintaining expansive open areas. However, the relaxing of these norms raises significant environmental concerns that cannot be overlooked.
Critics, including environmental activists and urban planners, express alarm over the potential negative implications of reduced open spaces. They caution that this decision could exacerbate urban heat island effects, increase local flooding risks, and hinder emergency access for fire engines. Furthermore, diminishing open areas can severely impact groundwater absorption, leading to long-term ecological challenges. The decision appears to undermine efforts toward climate action and achieving net-zero emissions, particularly as it encourages increased reliance on artificial lighting and mechanical ventilation instead of harnessing natural resources.
