The number one thing clients tell me after we finish: "I didn't realize it could feel this easy."

That's not an accident -- it's how I set things up from the start.

Here's how working with me actually goes:

Step 1 -- We talk. You book a 2-hour in-home consultation. I come to you, I look at the space, and I tell you exactly what I think. No fluff.

Step 2 -- We plan. I put together a complete design plan for your project. You don't have to source anything, make decisions in a showroom, or manage a single contractor. That's my job.

Step 3 -- We build. I manage the renovation from start to finish. I deal with the trades, the timelines, the surprises. You stay out of it unless I need you.

Step 4 -- You love your home. Not a "it's fine" kind of love. A real, genuine, I-can't-believe-we-waited-this-long kind of love.

I work with busy professionals across Oakville and GTA West who are ready to invest in their home and want someone they can fully hand this off to. If that's you, let's talk.

  • Christine was amazing right from the beginning. She brought not only design choices & recommendations, but also the required contractors to complete the work. She communicates well & gathered from us what we wanted in our kitchen & main level living space. I would recommend Christine for your renovation. She will take your living space and turn it into something you will look forward to & enjoy.

  • I highly recommend Christine. She works beautifully with any buddget and has an incredible ability to understand your style, then translate it into a space that feels cohesive & elevated. Getting her professional input is absolutely worth it - everything comes together correctly the 1st time, instead of experimenting with different ideas & getting frustratedd. She makes the entire process easier, clearer and genuinely enjoyable.

    Yvette

  • Our experience with Christine Da Costa Interiors has been nothing short of outstanding. From the start of our main floor-kitchen renovation to the finished product, Christine has been a stellar & integral part of the overall success of our project. We would absolutely highly recommend Christine!

  • We used Christine’s ‘Designer for A Day Package’ to help us transform our dining room and convert our formal living room into a main floor office. We had a concept of what we wanted and with Christine’s consultation, together we developed a great plan for a fantastic space.

  • Christine was recommended when I was having difficulty picking a colour for my north facing condo. She was so helpful in guiding me to the colour which not only brightened my space but complemented by dark furniture. We decided to colour drench my condo and I am so pleased with the results. It helped enlarge the space. I highly recommend Christine, here delightful personality & professional knowlege made her a joy to work with

    Janet

  • Christine was a pleasure to work with for our home transformation.  We do not use that word lightly for what was created in our new living space.  Christine made everything possible from our initial meeting, explaining her extensive services, to the beautifully finished work of art.

    — Paul and Maureen

  • Christine is an exceptional designer. Her sense of flare, attention to detail and collaboration is fantastic. Christine helped me with my entire main floor design project - from choosing paint colours to helping with ceiling design and hardwood floor design and of course layout and furniture choices.

    — Sharene

  • I had the pleasure of working with Christine on my home office project. She provided me with several innovative designs and furniture options for the various options. Her customer service was great and I’d recommend her for your future design needs.

    — Mike

  • We contacted Christine immediately once we decided on renovating our powder room, kids bathroom and mudroom flooring. She already had a strong grasp on our style and risk tolerance (for finishes and decor) from our work together in 2017 when she helped with a major main floor renovation.

    — Navneet

  • I’ve worked with designers before where I felt they didn’t listen to what I liked, Christine seemed to understand what we liked just by talking with us. She came to present our basement renovation with the most amazing fabrics.

    — Kathleen

  • Christine has been wonderful to work with! She knew exactly what we wanted and executed it effortlessly.
