Holly Costello Interiors Interior design. Retailer of Graber Blinds. I believe your space should be a reflection of your unique personal style.

Since graduating from Lawrence College (St.John's, NL) in 2004 with a diploma in Interior Decorating and Design, I have been working in the field with a long list of clients, in both residential and commercial settings, helping them by creating beautiful spaces. I love to work in many different design styles, whether it be full-scale new builds or renovations and planning, to decor and finishing t

ouches. Along with Graber Blinds and the many fabric lines I've been carrying for years now, I'm so excited to announce that I am the western Newfoundland retailer for FAT Paint.

These stairs really moved us! We kept the original staircase on the main floor and added a new flight going to the basement. Working with the finest craftsman to create a seamless design between old and new is what we do.

If you have a feature in your home you want to keep, we’d love to help you do that.

When Swans live in your client’s neighbourhood, they naturally become the main inspiration for a closet, turned powder room. 🦢

We love turning small spaces into a big deal!
