Buying or building on a plot in Saket? Read its kundli first: earthquake zone and foundation, groundwater, water quality, rain and the harvesting rule, Vastu for its facing, and the cost of the house.
103%groundwater pumped vs safe yield, over-exploited (CGWB 2025)
6–65 mdepth to water before the monsoon (CGWB 2018)
Saket, Delhi is in seismic zone IV: high damage risk.
Design the frame to IS 1893 and detail the steel to IS 13920: stirrups bent to 135°, closer stirrups near every beam and column joint, and column laps in the middle half of the height. It adds only a few percent to the steel.
Stilt parking needs care in this zone: an open ground floor under walled floors is the soft storey that fails first in earthquakes, so the structural engineer must design for it.
For a G+1 house, isolated RCC footings are the usual starting point on firm soil; filled ground, black cotton soil or a high water table call for a raft or piles. A soil test (about ₹15,000 to ₹40,000) settles it before the drawings.

Jal Groundwater level and borewell
Act on it
Groundwater is over-exploited here: more is pumped out than rain puts back.
Delhi's South district pumps out 103% of the groundwater it can safely take each year (CGWB 2025), which CGWB rates over-exploited.
That is down from 255% in 2017.
Before the monsoon, the water stood 6 to 65 m below ground in CGWB's 12 monitoring wells (2018); most read over 40 m. 83% were deeper than 20 m, out of reach of shallow borewells.
Expect a deep borewell to fall further. Plan rainwater recharge into the ground from day one, and a storage tank for municipal or tanker water.
3
Neer Groundwater quality
Needs care
CGWB found fluoride above the safe limit in some of Delhi's South district's groundwater.
Test the borewell water on your plot (TDS, fluoride, nitrate and hardness) before you rely on it, and budget an RO or a fluoride filter for drinking water.
4
Varsha Rain, rainwater harvesting and recharge
Act on it
Rainwater harvesting is mandatory for this house under Delhi's rule.
Building Bye-laws, 1983 as amended by MoUD (2001); Unified Building Bye-Laws for Delhi, 2016; Master Plan for Delhi 2021: plots of 100 sq m and above.
It applies from a plot area of 100 m² or more; your plot is 167 m².
Saket, Delhi gets about 721 mm of rain a year (NASA POWER, 2006 to 2025), 81% of it from June to September. A 1,170 sq ft roof can send about 66,615 litres a year back into the ground.
That needs one recharge pit with a 200 ft recharge bore, costing about ₹1.4 lakh to ₹2.2 lakh with GST.
By Vastu, underground water belongs in the north-east, which is where the recharge pit or sump usually goes.
5
Vastu Facing and layout
Favourable
North-facing plot. North-facing plots are among the most sought after in Vastu, linked with wealth and growth.
Main door: in the middle-to-east part of the north wall (padas N3 to N5).
Kitchen in the south-east (or north-west), cooking facing east. Master bedroom in the south-west. Pooja room in the north-east.
Stairs in the south, west or south-west, climbing clockwise. Toilets in the west or north-west, never in the north-east or the centre.
Overhead tank over the south-west; borewell, sump and recharge pit in the north-east; septic tank in the north-west. Keep the centre of the house (brahmasthan) open and uncluttered.
6
Nirman Construction cost and approvals
Favourable
About ₹56 lakh to ₹62 lakh for a G+1 house of 2,340 sq ft, finished to a standard specification.
Taken at 65% ground coverage: 1,170 sq ft a floor on a 1,800 sq ft (200 gaj) plot. Your local bye-laws set the real coverage, setbacks and height for the plot size.
Structure only: ₹40 lakh to ₹44 lakh. Premium finishes: ₹70 lakh to ₹82 lakh and up. Rates are per sq ft of built-up area with GST, from our own priced BOQ.
Not included: approval fees, a basement, boundary wall, lift, solar, borewell and interiors.
Before work starts: building plan approval with architectural and structural drawings, then the occupation certificate at the end, which in most states needs the rainwater harvesting pits built.
Groundwater, water quality and rain figures are for Delhi's South district as a whole: the government does not publish them by sector or locality. Vastu notes are traditional guidance, and the foundation and cost lines are starting points. A site visit, a soil test and a water test on your plot give the exact picture.
Frequently asked questions
Is it safe to build a house in Saket, Delhi?
Yes, with the right design. Saket, Delhi is in seismic zone IV: high damage risk. Groundwater is over-exploited here: more is pumped out than rain puts back. Plot Kundli on this page reads all six: ground and earthquake zone, groundwater, water quality, rain and rainwater harvesting, Vastu and cost.
What is the groundwater level in Saket, Delhi?
Delhi's South district pumps out 103% of the groundwater it can safely take each year (CGWB 2025), which CGWB rates over-exploited. That is down from 255% in 2017. Before the monsoon, the water stood 6 to 65 m below ground in CGWB's 12 monitoring wells (2018); most read over 40 m. 83% were deeper than 20 m, out of reach of shallow borewells.
Which earthquake zone is Saket, Delhi in?
Seismic zone IV under IS 1893 (Part 1): 2016. Houses here need the ductile steel detailing of IS 13920 and a structural design that accounts for stilt parking.
Is rainwater harvesting mandatory for a house in Saket, Delhi?
Mandatory for plots of 100 sq m and above. That needs one recharge pit with a 200 ft recharge bore, costing about ₹1.4 lakh to ₹2.2 lakh with GST.
How much does it cost to build a 200 gaj house in Saket, Delhi?
About ₹56 lakh to ₹62 lakh for a G+1 house of 2,340 sq ft, finished to a standard specification. Structure only: ₹40 lakh to ₹44 lakh. Premium finishes: ₹70 lakh to ₹82 lakh and up. Rates are per sq ft of built-up area with GST, from our own priced BOQ.
What is a Plot Kundli?
A free report on a plot before you buy or build on it, read in six houses like a kundli: Bhoomi (ground, earthquake zone and foundation), Jal (groundwater), Neer (water quality), Varsha (rain and rainwater harvesting), Vastu (facing and layout) and Nirman (cost and approvals). It is built from CGWB, NASA POWER and BIS figures and the state's building rules.
