“Home is so much more than skin-deep beauty and fleeting trends. The practicality and function beneath the surface is the foundation to meeting our clients’ needs and goals, and we tap into this for every project.” – Diana Bastone

About Me Image

Diana Bastone

Principal Designer and Owner

Diana is a graduate of the Interior Design program at Toronto Metropolitan University (formerly Ryerson University), but her pathway to design started in childhood, when she flourished through her love of drawing and painting as a means of creative expression. As a young girl, she recalls watching her mother renovating and decorating their beautiful home, chiming in with her opinions and preferences, and seeing the transformation of the family home. She recalls how different she felt in the final result. It’s that transformative feeling that she wants each of her clients to experience.

 In adulthood, the field of interior design allows Diana to channel her innate creativity whenever she finds herself sketching concepts, working with colour and seeing the final product, whether it is custom millwork or furniture. Diana’s discerning taste and design style is sophisticated yet approachable, qualities visible in each of her projects through the years.

Diana’s formal education combined with 30 years of practical experience have equipped her with skills spanning every facet of interior design, from construction to space planning, millwork design and custom décor.

Diana also has a passion for the business side of interior design, and has continuous coordination and communication with her team of contractors, suppliers and clients. From concept to completion, Diana prides herself on her robust supportive roster of professional collaborators, each contributing their unique talents to carry out the shared vision for success.

“My design philosophy is that our home has a profound impact on our well-being. If we surround ourselves with beautiful spaces that are also practical for everyday living, our home can bring us much joy to our daily life.” – Diana Bastone

Ashley About Me

Ashley Tomasone

Senior Designer

With over 10 years of interior design experience, Ashley brings a keen eye and meticulous attention to detail to every project at Diana Bastone Designs.

Ashley's distinctive design approach seamlessly connects fashion and interior design, recognizing both as authentic expressions of one's self. She believes that a home narrates a story of one's personality, life experiences, history, and holds memories that can be passed on through generations. Understanding and getting to know each client is the key to truly making a house feel like a home.

While there are various facets to interior design, custom millwork and space planning stand out as Ashley's favorite areas. These aspects set the flow and foundation of a home, contributing to the creation of well articulated and functional spaces that are essential to every project.

Ashley is unafraid to roll up her sleeves, investing the time and effort needed to complete a job. Her passion for construction and the building process allows her to collaborate seamlessly with clients, contractors, and trades, ensuring a smooth project from start to finish.

Her love of travel serves as a continuous wellspring of motivation and inspiration in the ever-changing world of design. The most rewarding aspect of her job is turning the client's vision into reality—creating spaces that are not merely lived in but cherished, where memories are made.
