Bob and Cortney Novogratz never do anything small. So when they bought their new 1926 castle in the Hollywood Hills they couldn’t just throw a regular housewarming party.
The design duo—and parents to Wolfgang, 18, Tallulah and Bellamy, 17, Breaker, 15, Five and Holleder, 10, and Major, 7—decided to a host a blow out construction party after they’d knocked down the original design of the castle but before they’d started revamping it.
In the second episode of PEOPLE’s new home design web series, The Castle Next Door, Breaker explains, “I think it’s a cool experience for people to kind of see what the house is like way before we do anything to do it.” Adds Bellamy: “I think some people are going to see the house and go, ‘Wow. It needs a lot of work.'”
Because they didn’t have a lot of time to prepare for the party, the family came up with a few simple ideas to spruce up the space. They hung up enlarged photos of what the castle used to look like, put out chalk and paint so people could sign their names on the house before it was repainted, and used a technique called “yarn bombing” to give the trees in the backyard some color.
“The priority was making it safe, making it interesting and letting the bones of the building speak for itself,” says Bob.
The family also brought in a DJ, a margarita truck and invited old friends and new.
“Construction parties are probably more fun than the actual construction,” says Bob, “but it’s a journey like anything and you got to enjoy the whole trip.”
