Matt Roloff, a star of TLC series “Little People, Big World,” is selling the Oregon farmhouse where he and his ex-wife, Amy Roloff, raised their four children. He is asking $4 million for the roughly 16-acre parcel, a portion of his approximately 109-acre pumpkin farm, according to listing agent Juli Martin of Luxe Forbes Global Properties.

“It’s too much now that I’m 60,” Mr. Roloff said. “I want to start to scale back a little bit.” 

“Little People, Big World” chronicles the lives of the Roloff family; Mr. Roloff, his ex-wife, and one of their children have dwarfism. The Roloffs divorced in 2016, and Ms. Roloff was bought out of the 109 acres in 2019. Ms. Roloff didn’t respond to a request for comment.

Mr. Roloff said he plans to build another home on the portion of the farm he is keeping, and will continue to grow pumpkins on it. He said he would split his time between the farm and his home in Arizona. 

The farm is located just outside of Portland in the rural community of Helvetia, according to Ms. Martin. The house spans about 5,400 square feet. The parcel for sale also includes various playgrounds built for the Roloff children, who are now adults. One includes a 40-foot-long pirate ship with a captain’s quarters, a main deck and bunk beds, Mr. Roloff said. A children’s play castle, roughly the size of a small home, was inspired by castles he saw while visiting Europe.

A replica of an old Western town has everything from a bank and a jail to a post office and a barbershop. The buildings are the size of small bedrooms, Mr. Roloff said, with secret passageways that lead to tunnels he built underneath them. Mr. Roloff also created a replica of a mountain range with hills and valleys. Among the mountains, he planted trees and added trails, a bridge and a small play cabin, Mr. Roloff said.

There is also a roughly 3,600-square-foot barn that has been turned into office space and has a one-bedroom apartment, Mr. Roloff said. The parcel, where the pumpkins previously grew, includes a former gift shop, he said. He has since moved the pumpkin operation to the other side of the farm, but said the soil on the parcel for sale can still grow pumpkins and other crops if the new owner chooses to do so.

The Roloffs bought the first roughly 33 acres of the farm in 1990 for about $185,000, Mr. Roloff said, and purchased adjacent properties over the years.

“Little People, Big World” has been on since 2006 and will air its 23rd season later this month.
