All About Marnie

Season 1, Episode 13

Rare and Recycled

A determined couple has found a 1960s gem of a beach home with a rare design element: a unique breezeway running through its center! While some may view the home as a teardown, the couple is serious about preserving its classic look and expanding upon the unique breezeway. Marnie faces one of her toughest challenges yet as she attempts to create a modern, fresh look without altering the structural design of the house. Along the way, Marnie and her crew run into issues the aging house has developed over time, like rotting posts under the back porch. Marnie must tackle the 50-year-old layout and transform this unique beach home into a fun space the family can enjoy for years to come.
