Hell has frozen over in the East Village.

The Hells Angels’ former headquarters — a famed relic of the neighborhood’s gritty past — is becoming rental apartments.

Real estate speculator Nathan Blatter flipped the six-story building at 77 E. Third St. in a $10 million sale finalized this week.

Now the developer will remake the HQ where bikers cracked their whips on the sidewalk and decorated rooms with swords into a hive of sterile, “standard, regular East Village apartments” for well-heeled millennials — the very population the Angels said they were trying to escape.

“We’re being harassed by the yuppies down here [who are] sitting on our bikes and pissing on the sidewalk,” biker Tony told The Post in March about fleeing the place the gang called home since the ’70s. “When the neighborhood was s–t, nobody minded us.”

The $2 million renovation will create two retail spaces on the ground floor where the clubhouse bar used to be — and one storefront could become a shrine to the burly bikers.

Blatter said he has been contacted by someone curating a Hells Angels museum, and another about a barber shop.

The new owner, Lower East Side property management company Better Living, hopes to finish the renovation by the end of 2020.

“The location is phenomenal,” Better Living’s Jonathan Sondry gushed. “It is a rare occasion to find a fully vacant building in Manhattan.”

The basement repair shop — equipped with a scissor lift that lowered motorcycles from the sidewalk — will be cleared out. The 16 “crash pads” once used by gang members — one was adorned with a swastika — will become 22 one- and two-bedroom units priced around $3,500 per month.

Sondry said he doesn’t plan to use the building’s history as a selling point, because he doubts oblivious 20-somethings will care.

“I don’t think it will make a difference to young students these days,” he said.

The crash pads were left in good condition, Sondry said: “I don’t think anyone lived there full-time. … There were more couches and less beds.”

The headquarters operated as a Hells Angels hostel.

“The main guys were telling me: ‘Anywhere I go in the world, I have somewhere to sleep,’” Blatter said. “It was just a pit stop for them.”

Blatter, who was told he was the first non-member in 40 years to be allowed inside, said when it came to doing business, the bikers showed the better angels of their nature.

“They were gentlemen,” Sondry said. “When you hear the name Hells Angels, I’m sure people get intimidated, but contrary to the stereotype of a motorcycle club, they were nice and easy to deal with.”
