The reconstruction of Patan Darbar Square is likely to take four more years, according to workers rebuilding and renovating the historical and cultural monuments destroyed during the earthquake of April 2015. 
The Kathmandu Valley Preservation Trust (KVPT) had initially targeted to complete the reconstruction work in five years starting early 2016. But workers involved in the reconstruction said that it is not possible to rebuild the monuments within the given deadline largely due to a short supply of the right wood and wood carvers and artisans with skills and knowledge in Malla and Lichchhavi era architectures created around more than 1,500 years ago. 

The heritage of Patan Durbar Square was heavily hit by the earthquake. Around 250 cultural monuments including durbars, temples, patis and pauwas (wayside public shelters)  were completely or partially destroyed during the earthquake. While some partially damaged structures like Krishna Temple, Bhimsen Temple, Visvesara Temple, Kumbeshwor and Radha Krishna temples have been rebuilt and renovated, the reconstruction of many other monuments like Char Narayan Temple, Hari Shankar Temple and two Mani Mandaps that suffered heavy losses is likely to take some more years. ... The shortage of workers with traditional woodcarving skills looks set to cause similar delays in the reconstruction of historical monuments in Kathmandu and Bhaktapur and the remaining areas of Lalitpur districts. The earthquake has damaged more than 239 monuments in Kathmandu and 114 monuments in Bhaktapur. Besides few structures made of metal and wood, majority of those structures are wooden structures.
