(CNN) -- San Diego County, California, authorities will burn down a house that they've described as a "bomb factory" and the site of the nation's largest cache of homemade explosives ever found in one spot.
The house, in an unincorporated area near Escondido, California, has been deemed too dangerous for bomb squads to re-enter because it contains two kinds of volative explosives, and the interior is too cluttered for bomb crews to negotiate safely, authorities said.
Authorities revealed their plan to burn down the house during a town hall meeting Tuesday night with residents concerned about public safety, San Diego County Sheriff spokeswoman Jan Caldwell said Wednesday.
The house's resident, George Djura Jakubec, 54, a computer software consultant, is being held in lieu of $5 million bail on bomb-making and bank robbery charges.
The house would be set afire some time between December 8 and December 10, if the skies are clear and winds are about 5 mph out of the west, which would allow the smoke to dissipate over nearby Interstate 15, said another sheriff's spokeswoman. Authorities plan to erect protective walls during the burn.
Bomb crews discovered two types of homemade explosives inside the house last week -- also the kind that terrorists worldwide favor: hexamethylene triperoxide diamine, or HMTD, and pentaerythritol tetranitrate, or PETN, which is now the target of new U.S. airport body scans and pat downs. Authorities didn't remove those explosives from the house.
Eight or 9 pounds of HMTD were found in the backyard after a gardener was injured when he accidentally ignited some of the material almost two weeks ago. One expert likened the 9 pounds to a large car bomb, which could blow out the house's windows and doors and damage adjacent houses.
Authorities are now investigating Jakubec's intentions.
Exacerbating the work of the bomb squad is the overwhelming volume of interior clutter that suggests Jakubec was a hoarder of papers, boxes and other items, officials said. Friction from moving any papers or boxes could cause hidden explosives to ignite, officials said.
Joy Colclough lives about 100 yards from the home, according to CNN affiliate KGTV.
She received a reverse 911 call earlier Tuesday, warning her of potential activity around the residence, but has not been asked to evacuate.
"It's not a convenient time. But I don't think there's any convenient time for having explosives next door to where you live," she told KGTV.
The additional HMTD discovered inside the house last week is in a bottle, Assistant San Diego County Sheriff Ed Prendergast said. PETN was also found inside the house, officials said.
"We have not removed it yet. It's too dangerous to move. Any movement can set it off," Prendergast said.
"We have a saying: We'll go as fast as we can but slow as we must," he added.
