Designing homes for life's best moments—by the shore and beyond.

At Cass Thurston Interiors, we specialize in crafting timeless, family-centered spaces that blend relaxed coastal style with functional, sophisticated design, creating homes where memories are made for generations to come.

Meet Cassandra

In 1965, a humble bungalow on Long Beach Island became the heart of my family’s coastal traditions and inspired my passion for reconnecting homeowners with the carefree LBI lifestyle. Splitting time between Long Beach Island and Clinton, New Jersey, I specialize in designing timeless, family-centered spaces that blend coastal charm with functional elegance.

From serene vacation retreats to year-round residences, every home I create is crafted with intention, honoring the joy and connection that make life’s best moments truly memorable.

  • Cassandra managed every aspect of the interior design for our beach house. She was so much fun to work with and really shared our enthusiasm for creating beautiful living spaces. She took the time to understand our tastes and preferences as she put together the plans. It was a huge project that would have been overwhelming to do all by ourselves. We are delighted with the finished product and couldn’t have done it without Cassandra’s expertise and excellent sense of style!

  • Cassandra is wonderful to work with! I was overwhelmed with all the decisions that I had to make in our new build and her help has been such a godsend. We spent hours picking out tile, vanity colors and wall colors and I am so excited to see how amazing everything turns out!
