“You know when there are times in your life where everything comes together and it just feels like it was so meant to be and everything feels right? That’s how this feels,” Maureen McCormick, 62, who played Marcia Brady, tells PEOPLE exclusively. “It’s so perfect.”

However, she admitted she has “no idea” how they’ll replicate the house’s memorable interior — on the show inside scenes were shot on a sound stage — in a space that doesn’t currently look anything like it.

“Our responsibility is that we don’t screw this up,” Drew tells PEOPLE with a laugh. “In the end, we want to make sure that what we do is exactly what this house should look like.”

They plan to fix up the landscaping around the front facade, Jonathan explains, but the interior will need to be drastically remodeled, since the house was never actually used for the show’s filming.

“I want to see the cast react to the house, because originally it was all studio space,” he says. “All the sets were on one level so when they used to walk up those stairs and it was a dead end. Now, they’ll be able to come into this house when it’s done, walk up the stairs and go to their bedrooms that they had when they were kids.”

Susan Olsen, who played Cindy Brady in the series, admits she feels a little bit of resentment toward the house because as a child, she asked the producers why they chose that house for the exterior and they told her, “I’ll have you know that if you walk into that house, it looks exactly like this set.”

“I racked my brains trying to figure out how that could possibly be and I finally asked my mom [who said], ‘Oh, honey, they were just trying to shut you up,” Olsen recalls. “I was lied to. It hurt my feelings all those years ago. There’s a nine-year-old inside of me saying, ‘See, see, I was right!'”

Olsen will work on the girls’ bedroom, the second floor landing and hallway and the jack-and-jill bathroom alongsideGood Bonesmother-daughter duoMina Starsiak Hawk and Karen E Laine. Although Laine understands they may have to compromise some aspects of the design because of the home’s layout, the one thing she says they must include on the property is a dog house.

“They’re going to cry,” Laine says of the Brady kids. “That’s our goal, to make people happy cry. Just have a lot tears, ruin whatever makeup you might be wearing and hug everybody.”

“There are six people and six kids that shared a bathroom with no toilet,” he jokes. “It had no toilet. You can’t get a permit for a house without a toilet and you shouldn’t be able to.”
