The seven cities tracked in this report are -- Delhi-NCR, Mumbai, Chennai, Bengaluru, Pune, Hyderabad and Ahmedabad.
"The Indian office space market has been plagued by an abject lack of viable space over the past four years, while demand has stayed doggedly steady," the report said.
The decline in office space was arrested in 2017 with supply growing by 7 percent.
"The overall transaction continue to substantially exceed supply and this has pulled down the vacancy level to 11.6 percent from 13.5 percent a year ago," Knight Frank said.
On rentals, the consultant said that the growth has been strong across markets with the exception of Mumbai that witnessed a 5 percent decline due to increased supply and vacancy levels.
The weighted average rentals rose to Rs 72 per sq ft per month from Rs 68 in 2016.
The report highlighted that the co-working phenomenon is gathering speed.
Across these seven cities, co-working space providers have taken up around 1.3 million sq ft of office space during the second half of 2017.
"The office leasing market maintained its strong fundamentals although expansion concern for the turbulence-hit technology sector is still prevalent," Knight Frank India CMD Shishir Baijal said in the report.The steady expansion of new age businesses such as co- working space providers is also one of the defining stories of 2017, he added.
