The Prime Minister's Office (PMO), currently housed in the South Block since 1947, is set to relocate to the Executive Enclave, a few hundred meters away, next month, NDTV reported, quoting government sources.

The Executive Enclave will house the PMO and other top government offices under the Central Vista project.

Besides the PMO, the Executive Enclave has the Cabinet Secretariat, National Security Council Secretariat, and a conferencing facility.

The new PMO is also closer to the Prime Minister's residence.

The need to construct the new office buildings was primarily due to space constraints. The old buildings did not have modern facilities.

Earlier, the ministries of Home Affairs and Personnel were shifted to Kartavya Bhavan-3, which the Prime Minister inaugurated this month.

In his address after inaugurating the building, Prime Minister Narendra Modi said India's administrative machinery had been operating from buildings constructed during the British colonial era.

He also spoke about the poor working conditions in these old buildings, which lack adequate space, lighting, and ventilation.
