meet kimberly

Over 15 years ago, while building her custom home, Kim turned her attention to the fashions of the interior decorating and design world – and she hasn’t looked back.

As the daughter of a contractor and a real estate agent, Kimberly thrived from a young age in a home building and renovation  environment.

Growing up, she was exposed to everything from groundbreaking, to framing, to designing and finishing interior spaces, to staging and decorating.

Kimberly taps into her extensive design, renovation and industry experience with every new job. This saves her clients time, money, and heartache.

Kimberly is a RESA PRO member and has completed Kimberly Seldon’s Business of Design I, II and III. She is also a graduate of Carleton University with a Bachelor of Arts.

thank yous

"I have used Kimberly Kostuch Interiors on my two major renovation projects. One was a complete bathroom renovation and the other an interior design and renovation of my new home which involved new floors, remodeled kitchen, structural changes and more."

"What I love most is Kimberley’s ability to ensure the owners personality and tastes are reflected. We found elements I loved and built on from there. Her ability to envision a space is amazing!"

– Elaine Mallory

"Since I like a traditional style, and my husband prefers a modern/contemporary style, we had difficulty agreeing on anything. After a consultation with KKI, we both felt empowered and motivated again to move forward with our build. Kimberly has a natural gift to find the common elements between two very different styles and combine them in a really fantastic way."

"We are thrilled with the finished product and enthusiastically recommend KKI to all of our friends and family."

– Bill and Lisa

"My husband and I used KKI to renovate the mainfloor of our home, approximately 1400 square feet, to create an accessible level for our son. We did not have a lot of time or energy to do shopping, measuring, comparing of prices, and calling of trades."

"Using KKI relieved all the pressure from us and made what could have been very stressful situation totally manangeable. We did not have to deal with any last minute panics or decisions. Kim listened to what we wanted and the end product was amazing. We are so grateful and would absolutely use KKI again!"

"I would never in a million years thought of your ideas that increased the size of a room specifically the living room, making the office into a bedroom, changing some paint colours, changing knobs in the kitchen to modernize and many other ideas that you so easily came up with."

"The job was taken care of in a timely manner and done to perfection. I would definitely use your services again if the occasion arose. Thank you again!"
