Pick your authority and plot size to see the allowable covered area, setbacks, floors and height limits under the current building bylaws — with a to-scale layout of your buildable area.
Blue = house · light blue = car porch · green = front open space · white = required setbacks
Side open space applies to the right side only.

How much you can build on a residential plot in Karachi depends on your authority — DHA Karachi, DHA City, Bahria Town or SBCA (the rest of the city). Two rules decide it together: the allowable ground coverage (a percentage of your plot per floor) and the compulsory open space (setbacks) you must leave open. The smaller of the two governs your buildable footprint.
In DHA Karachi, coverage runs from 90% (up to 200 sq yd) down to 50% (701 sq yd+). DHA City Karachi is similar — 90% on small plots down to 50% on the largest — with a finer band structure. Bahria Town Karachi allows 70% on 125 sq yd villas, 65% on 250 sq yd, and 50% on 500 sq yd and above. Across DHA schemes and Bahria, residential plots are limited to Basement + Ground + 1 (Bahria allows basements from 500 sq yd). Under SBCA, plots up to 399 sq yd may rise to three storeys (35 ft) while 400 sq yd and above are capped at two storeys (25 ft).
How much can I build on a 240 sq yd plot in DHA Karachi?
A 240 sq yd plot sits in the 201–400 band — 75% coverage, roughly 1,600 sq ft per floor after setbacks, and around 3,200 sq ft over Ground and First floor, plus a basement.
How many floors can I build in Bahria Town Karachi?
Residential villas allow Ground + 1 floor, with basements permitted from 500 sq yd upwards, and a 30 ft height limit.
Are corner or park-facing plots different?
Yes. Corner, amalgamated, park-facing and special-zone plots have their own rules, and bylaws are amended periodically. Use the calculator above as a quick guide, then request a free feasibility review for an exact, plot-specific answer from a Zell advisor.
