Avvad Spaces LLP, Ghatkopar

A residential and commercial project by Avvad Spaces at Ghatkopar in Mumbai, on a plot bounded by 12.2 m, 9.8 m and 6.1 m roads. Four residential wings, A to D, rise above a ground floor of five shops, residential and commercial entrance lobbies, electrical meter rooms for the wings, a fitness centre and a 6 m fire-engine drive, with a basement and two mechanical car-parking towers served by car lifts. The basement holds the underground water and fire tanks, the pump rooms and the sewage treatment plant. The architecture is the architect's; our scope is the MEPF design and the environmental clearance layouts.

We issued the external coordinated layouts for the environmental clearance in February 2026 and revised them in May and June 2026, with the EV charging and the solar PV and hot water layouts in May. Water: underground domestic tanks of 27,000 to 35,000 litres for each wing, flushing tanks of 32,000 litres for wings A and D and 28,000 litres for B and C, a 6,000-litre tank for the shops and two 3,00,000-litre fire tanks as the fire NOC requires; the supply from the corporation main, a bore or tankers passes through filtration, a softener and chlorination to hydropneumatic tanks, with recycled water for flushing in its own lines. Sewage: an MBBR plant in the basement - screen chamber, equalisation, anoxic tank, two MBBR stages, a tube settler, ozone disinfection, pressure sand and activated carbon filters and a sludge holding tank - with a sewer trap and drop manhole before the municipal line. Rain: storm water to the road drains, and rooftop and surface water through desiltation pits and a grease-and-oil trap to recharge pits of 2.5 x 2.5 x 2 m, each with a 50 to 60 m bore. Fire: a 150 mm external hydrant ring with single-headed hydrants, 63 mm outlets and hose boxes with 15 m hoses. On the roofs, 540 W solar PV panels and 125-litre solar hot-water panels share the four terraces, and the basement layout places the EV chargers; the DG set's exhaust rises to the terrace and the organic waste converter has a double-height space.
