We started off wanting a kitchen refresh, a powder room refresh, and a little here and a little there. Soon appreciated Katherine was the designer for us! Our main floor has never looked more lovely and styled with the comfort and joy which suits us perfectly. "Living through a reno is joyful", said NO ONE. Katherine made the experience as liveable as possible and the end result is a dream. (So much so, we are still throwing snowballs....on deck is the laundry room makeover booked for early 2024.) Could not have put together the design or navigated the suppliers or trades without her professional expertise and guidance. Heartfelt thanks to Katherine JOY Interiors!! **Comment from Katherine Joy Interiors:** > What a delightful message! Thank you for your kind words and for entrusting me with your home transformation.

It was lovely to be apart of your design journey! **★★★★★ — meganberkal, Dec. 2022** > Katherine was incredible to work with. She greatly exceeded our expectations of what working with a designer could be. Going into our basement renovation we wanted someone to help design the space so that it would be functional. Katherine was the perfect partner to work with. She brought her expertise in both design and life to create a space that went beyond what we could ever imagine it could be. She thought of things we never would have come up with on our own and created not a new basement but a whole new living space within our house. She’s a pleasure to work with and incredibly respectful of requests regarding the scope and budget of the project. We cannot get over how well she listened to what we had said we wanted and had it executed beyond what we ever thought the space could become. She has a real talent for making a space both beautiful and functional. I highly recommend working with Katherine on any of your design projects, I know we will be working with her again. **Comment from Katherine Joy Interiors:** > Thank you so very kindly for this JOYous review!! It was my absolute pleasure getting to know you more during this project and I love the end results as much as you do! And.... I will look forward to working with you on your next design journey any time! **★★★★★ — HU-205212407, Dec. 2022** > Katherine is the best. We had never used an interior designer before but we were so impressed with Katherine. She helped us make our new townhome into a beautiful home that we call home. Katherine’s vision was spot on to what we wanted. I wouldn’t hesitate to call her anytime she goes above and beyond. **Comment from Katherine Joy Interiors:** > Much appreciated for your lovely review. I enJOYed watching your new townhouse transform into a warm and inviting home! Thank you for including me on your design journey! **★★★★★ — HU-319471675, Nov. 2022** > I have known Katherine for over 10 years and we have worked together professionally so when it was time to re-do my 1973 back split home in Newmarket, I did not hesitate to call Katherine. Our meetings were smooth and my needs and desires were turned into 3D drawings that accurately reflected the overall vision. The contractors that Katherine referred me to were top notch. The materials, finishes and colours were beautiful and again reflected the vision I was hoping to achieve. Katherine is the consummate professional and a JOY to work with. **Comment from Katherine Joy Interiors:** > I'm deeply grateful for your touching message! It brings immense JOY to my heart that the transformation of your home has brought you satisfaction, and I'm delighted to know it will be a source of enjoyment for years to come! **★★★★★ — Blanca Lewis, March 2022** > Incredible renovation made possible with Katherine’s vision .

The largest challenge for these clients was keeping the update to just one area. The original furnishings in their living area limited these clients to the type of entertaining as they only had seating for 4 guests. The kitchen layout was not ideal either as the cook was always stuck in the U-shaped counter. These clients are semi retired and wanted to invest in upda… - [Three Best Rated 2020](https://www.houzz.com/hznb/projects/three-best-rated-2020-pj-vj~6023074) - Location: Not specified - Photos: 1 - Description: Thank you to my wonderful clients for allowing me to add JOY to their projects and for the amazing team of contractors that bring my design ideas to life! - [Three Best Rated - Award Winner 2018, 2019](https://www.houzz.com/hznb/projects/three-best-rated-award-winner-2018-2019-pj-vj~4624667) - Location: Newmarket, ON - Photos: 2 - Description: https://threebestrated.ca/interior-designers-in-newmarket-on - [Community Living Central York](https://www.houzz.com/hznb/projects/community-living-central-york-pj-vj~5920449) - Location: Newmarket, ON - Photos: 20 - Description: I had the pleasure of volunteering my design services in creating a welcoming home for the many guests that visit this community living centre.

A: There was only 2 small walls in the dining room with painted walls and they were Benjamin Moore Balboa Mist. The rest of the interior walls were pine. **Q: Love the colour palette of this kitchen! Would appreciate the names.** *(in Photo Questions)* We are looking at remodelling our kitchen and trying to combine wood and painted cabinetry as I love the warmth of wood but we need a change from an all oak 1980's look. I would appreciate the names of the colours as the cabinets do not seem to be a bright white and I like the richness of the wood stain. Thank you. A: Thank you for your interest in this kitchen design project. This kitchen cabinets are painted Benjamin Moore OC-65 Chantilly Lace and the wood is maple stained in a medium walnut stain. The counters on the white cabinets are Cambria Wellington and the island is Cambria Bellingham. It is a perfect pairing...just like salt and pepper or vanilla and chocolate. With JOYous wishes, Katherine **Q: Mirrors** *(in Photo Questions)* Where can I find the mirrors? Do they have a special name? A: These are back lit mirrors and you can find them in most bathroom stores. They give any home bathroom that hotel feel! **Q: I Love The Back-splash** *(in Photo Questions)* Can you provide specifics on the manufacturer, color, type of material (stone, ceramic, porcelain). A: This is from Tilemaster in Aurora, ON. http://www.tilemastercanada.com/tiles-backsplash-stone It is a natural stone. **Q: I Love The Backsplash Too...** *(in Photo Questions)* Can you please provide feedback on the manufacturer and color. In addition, is the backsplash stone, porcelain, ceramic? A: This is a marble from \#TILEMASTER in Aurora, Ontario. **Q: Beautiful! Will you please share the dimensions of the shower?** *(in Photo Questions)* . A: Thank you for your comments... this shower is 4x8 which allows the wheelchair to completely turn around inside the shower. Best wishes for a JOYous day!
