“Hello Ania, It’s easy to forget what the transformation was like. Astonishing to me to see the before and after pics…so many parts and layers.  You did an AMAZING job!!!”

All the Best, Frank, May 2022 

Hello Ania,
Linda and I simply wanted to say thank you for your part in helping make our dream become a reality. Few people will ever appreciate the work that you did and the painstaking time that was involved. Aside from a normal course of construction we were faced with an early winter in November, a Global pandemic  in March and of course supply chain issues at the same time. Everyone involved found a way to make it work.
Your personal interest in our backyard project can not be expressed into words. We can only say thank you once again from the bottom of our hearts. Please enjoy the attached photos.
Warmest regards,
Frank and Linda

“…Thank you for all your help with the selections.  My next project will be the piano room in time. ( I will call on your expertise).
I can’t wait for all these pieces. It’ll be great. I love your ideas and taste.
My house is coming together just beautifully and I love it !!
Talk to you soon !”

I wanted to thank you for your assistance with our project of the duplex conversion on Roxton Road in 2015. Both the client and myself were extremely impressed with your ability to produce a colour scheme that worked perfectly with the clients vision.

Your consultation during the process was invaluable.  The Client produced a promotional video of the final project.

I have a project coming up and would like the opportunity to work with you and your company again if you will be available. Thanks again for your hard work and due diligence it was very much appreciated.

 “Dear Ania, I feel very fortunate to have found you. The option to be able to work with you directly, one on one has helped move the process along quicker and more efficiently. The focused ‘Priority List’ we put together was accomplished and concluded in a timely, professional manner. As a full time very busy Professional myself, my trust in both your work ethic and beautiful Interior Design results were earned quickly, allowing me to focus on my own work and leave the interior design and project management in your hands. I look forward to starting our next ‘Scope of Work’ this month.

I recently visited the model home that you staged for Fernbrook Homes in Aurora. I want to say that I think you did an amazing job…the place is decorated to perfection!  I wanted to ask what colour you used on the walls in the nursery…I absolutely love it and hope to use it in my nursery. Thank you in advance.
