Christine likes to approach a room like a woman’s outfit:

β€œBuy great, timeless pieces that have longevity and accessorize with less expensive items! Make this your design motto and you will be successful. β€œI’ve always loved how Fashion intersects with Interior Design, and frankly I cannot get enough of both. If you love the clothes in your closet, then why shouldn’t that style or colour be reflected in your home? If you’ve got great style…so should your home β€” β€œDecorate as you dress” is her motto!

    β€” Paul and Maureen

  • We used Christine’s β€˜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.

    β€” Chuck and Fiona

  • 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.

    β€” 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.

    β€” 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.

    β€” 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.

    β€” Kathleen

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