The admission came when opposition members raised the issue in the state assembly.
Apartments in Patna and other cities and towns in Bihar are dearer in comparison to New Delhi and other big cities, he said while replying to a debate on the Urban Development and Housing Construction department's budget of Rs 2115.90 crore for 2013-14.
The builders are 'making a kill' by selling apartments at the rate of Rs 4000 per square feet or more which made housing in Patna dearer than other major cities in the country, he said.
Kumar also announced that Bihar would be made slum-free over the next couple of years and his department has undertaken construction of basic infrastructure and civic amenities like drinking water, road, drainage in 56 slums. The work will be completed by the next monsoon.
Altogether, 1841 slums have been identified in Bihar where basic infrastructure and amenities will be laid down in the next couple of years to make the state slum-free, he said.
