Bungalow B, Bavdhan

A bungalow on a plot of 286 sq m, with 500 sq m of construction, next to the one above: a lower ground floor and three floors above, with a living room, kitchen, dining room, guest bedroom, servants' room, a garden and an outdoor dining area, three showers on the first floor, and a terrace with a powder toilet and a pantry. A lift connects the floors. The brief from the owner's input sheet is a full one: a diesel set for the whole load, a three-phase CT meter, a UPS for lighting and low-voltage loads, a stabilizer, solar power, power-factor improvement, surge protection, a lightning arrestor and home automation; an underground tank with water treatment, a hydro-pneumatic pumping system, a heat pump and solar hot water, rainwater harvesting, landscape irrigation, a basement dewatering and sub-soil drain system, and single-stack drainage with sound-proof pipes and sunken toilets.

Water: on the people-based method 10 people at 450 litres a day plus 1,000 litres for the landscape need 5,500 litres a day, with 11,000 litres of underground storage, a 5,500 litre overhead tank and 10,000 litres of raw water for a tanker; on the fixture method the lower ground floor, ground floor, three first-floor showers, second floor and terrace add up to 420 litres a minute, and 45 minutes of storage is 18,900 litres - so an underground tank of 20,000 litres and an overhead tank of 5,000 litres were chosen. Layouts: the internal and external services layout was drawn on five sheets from the lower ground floor to the terrace, with the electrical lift duct, the HVAC duct and the shaft sizes marked on the architect's plan, and with each cutout and sunk-slab depth - 150 and 200 mm - written beside it (R0, 4 November 2025); the combined internal and external plumbing layout followed on 1 December 2025. The services were issued for approval on 12 and 20 November 2025.
