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. 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.

NJ designer Cass Thurston blends coastal style with family-centered living.

  • 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!

  • I would highly recommend Cass Thurston Interiors! Cass was wonderful to work with and really understood our vision. If you’re looking for a true “beach girl” behind your home interior design then look no further. Cass helped us furnish our new build in Ship Bottom last year. She understood that we wanted beach chic that was also functional since we have three small children. She helped create a beautiful, homey beach oasis for us!

  • Cassandra (Cass) is a pleasure to work with. Her knowledge of construction enhances her ability to create the perfect space. She listens and was flexible to our needs as we looked to update our home. She is easy to like and in addition to having fun with your project you will also gain a friend!

Every family has a story - let’s design a home that tells yours.

We’d love to hear what you’re dreaming of, whether it’s a renovation, a new build, or a space that simply needs to feel more like you.
