The demolition, which started on October 3, will take at least a fortnight to complete, they said.
Spread over an area of 28,000 square feet, the house where Tendulkar has stayed along with family during his sojourns to the hill station, is being demolished for encroachment after Narang's plea for relief was dismissed by the Supreme Court.
"Iron has been used extensively in constructing the building which is very firm and it will take at least a fortnight to complete the demolition as almost the entire structure has to be demolished," Naib Tehsildar (revenue official) Dayaram said.
Narang had initially taken permission from Cantt Board Landhour to repair a tennis court at the site but later erected a three-storey building there despite the board's objection prompting the latter to approach the court, according to officials.
