They need to be functional, but also welcoming, and inspiring. I collaborate with homeowners to design distinctive kitchens and bathrooms that work as well functionally as they do visually. I also design cabinetry for home offices, built-ins, and furniture. I particularly enjoy solving the problems of challenging spaces and turning your wish list into a features list. ### Services Provided - Kitchen Design - Custom Cabinets - Bathroom Design - Custom Kitchen Cabinets - Custom Bathroom Vanities - Custom Pantries - Laundry Room Design - Universal Design - Mudroom Design - Pantry Design - Basement Design - Wine Cellar Design - Kitchen Remodeling - Bathroom Remodeling ### Areas Served - Boston - Cape Cod - Cambridge - Newton - Somerville - Waltham - Brookline - West Roxbury - Arlington - Jamaica Plain - Lexington - Watertown - Wellesley - Belmont - Winchester - Nantucket - Weston - Charlestown - Brighton - Chestnut Hill - Newton Center - Newton Highlands - Newton Lower Falls - Newtonville - Roslindale - Wellesley Hills - West Newton ### Typical Job Cost \- 0 ## Business Details | Field | Value | | --- | --- | | Business Name | CW Design, LLC | | Address | Coolidge Corner, Brookline, Massachusetts 02446, United States | | Phone | (617) 733-4201 | | Website | http://www.cwdesignllc.com | | Followers on Houzz | 642 | **Social profiles:** - Facebook — https://www.facebook.com/cassiawynerdesign - LinkedIn — https://www.linkedin.com/in/cassia-wyner-31916b/ - Blog — www.cwdesignllc.com ## Contact - **Houzz profile:** [CW Design, LLC](https://www.houzz.com/professionals/kitchen-and-bath-designers/cw-design-llc-pfvwus-pf~402745315) - **Website:** http://www.cwdesignllc.com - **Phone:** (617) 733-4201 ## Credentials **Certifications & Awards** - Best of Boston Home 2021; Best of Houzz 2013-2025; Boston Design Center Design Services; NKBA national award for bathroom 2020; Grand Prize Winner, Gerrity Stone competition 2010; Designer for A&E show 'Fix This Kitchen'; Kitchen Designer in Boston Globe Magazine, "Asian Fusion" 2009 - **Best of Houzz:** 17 awards (2013–2026), for Service, Design. ## Reviews **Overall rating: 5.0 out of 5 — 66 reviews** *Aspect averages:* - Work Quality: 50.0 - Communication: 49.0 - Value: 50.0 ### Reviews **★★★★★ — HU-951094522, Feb. 2026** > We had an incredible experience working with Cassia on the complete renovation of three full bathrooms in our Beacon Hill townhome. From the first meeting through the final installation she was thoughtful, meticulous, and completely invested in bringing our visions to life. > A historic property comes with its own unique challenges and Cassia navigated them flawlessly. She struck the perfect balance between honoring the architectural integrity of our home while incorporating every modern comfort. What could have been overwhelming felt effortless because of her expertise and guidance. > Equally impressive was the respect and admiration she earned from our contractor and every tradesperson involved. They consistently praised her clarity, organization, and professionalism. The project ran smoothly because she communicated so effectively. > The finished bathrooms are beautiful and perfectly tailored to our home and lifestyle. Working with Cassia was seamless and enjoyable. **Comment from CW Design, LLC:** > Wow thank you so much. It was a great partnership all around, and I look forward to working with you and the team again! **★★★★★ — Karen, Dec. 2025** > Cassia was great! Cassia designed and oversaw the renovation of our kitchen, dining room, family room and 2 bathrooms. She worked really well with our contractor and made his job a lot easier because she was pleasant to work with and her designs were precise. Her designs transformed our living space into an open, bright, inviting place that we will enjoy for years! We recommend CW Design for your next home design project. Thank you, Cassia! **★★★★★ — Kornelia Polyak, Nov. 2025** > Cassia is great. I worked with her on complete redone of two bathrooms and kitchen. She came up with a design that exactly what I wanted, she made the purchase of things needed super easy by taking me to showrooms and just picking everything that I liked. She supervised the project to make sure it's done according to plan and coordinated with contractor. We love how our new baths and kitchen look. I highly recommend her. **Comment from CW Design, LLC:** > Your bathrooms look beautiful and the kitchen is completely transformed! Thank you for the recommendation. Enjoy! **★★★★★ — akoskey1, Nov. 2025** > Cassia is the perfect blend of creative and operational. She was instrumental in guiding the team (tiler, builder, etc) on details I would NEVER have thought of as a first time bathroom renovator. As an example, my house is old and has slanted floors. I picked a tricky tile for that and she worked directly with the tiler on how to make that look good! > She also helped me avoid some ugly decisions and I am super happy with how the bathroom turned out. She also helped keep the contractor focused on my project and helping me around the house on smaller projects like a built-in window seat. She is a jack of all trades. Highly valuable!! Thanks Cassia! **Comment from CW Design, LLC:** > Thank you! I had such fun working with you and just love all the things we picked out. **★★★★★ — Akiko Shimamura, Dec. 2024** > We are so grateful to Cassia for designing and overseeing the renovation of our condo kitchen and 2 full baths. Thanks to Cassia's expertise, our rooms are beautifully designed with gorgeous, functional, high quality materials and fixtures. Cassia understood our priorities and tastes, and worked within our budget. She communicates clearly and always responded promptly to our questions. She partnered closely with our contractor to oversee the project - this was critical for us since both my husband and I have demanding work schedules. She also smoothly managed any unexpected challenges that arose during the project. For example, when our timeline was set back by an unexpected logistical issue, Cassia took care of rescheduling all the deliveries and worked with the suppliers. When new structural constraints were revealed, Cassia quickly came up with alternatives. She is a lovely person who is a pleasure to work with. I highly recommend Cassia and would welcome an opportunity to work with her again. **Comment from CW Design, LLC:** > Thank you so much for the rave review Akiko. Your project was not without its challenges, but we worked through them all together and learned some along the way! I'm so happy to hear you are all enjoying your 'new' home. It looks great! **★★★★★ — Beth Parkinson, Oct. 2024** > Cassia helped us renovate a bathroom. Her sense of design and her attention to detail resulted in a beautiful space that we love. Our general contractor commented on the excellence of her plans translating into a project that was easy to implement. I highly recommend Cassia for any kitchen or bathroom renovation. She is lovely and easy to work with. **Comment from CW Design, LLC:** > Thank you Beth. It was so fun to work with you, and despite the distance it came together beautifully! **★★★★★ — Diane Lynch, Oct. 2024** > Cassia recently worked with us to design and install a new kitchen, pantry and bar area in our home. The project included installing a new wood floor and upgraded HVAC and communications network throughout our entire first floor. Cassia was a pleasure to work with in many ways. She listened carefully and incorporated our needs and preferences into the design plans throughout the entire process; she was flexible about timing and could work around our schedules; she worked collaboratively and effectively with our contractor and his staff; her knowledge of materials and sourcing options is excellent; she is an excellent communicator. We love the final product of our work together -- it is exactly what we wanted. **Comment from CW Design, LLC:** > Diane, I couldn't be more pleased with the outcome of our project together. It's music to my ears when I hear how well everything works together and how happy you are enjoying the space with friends and family. Every designer's goal. The best part of my job is getting to know the families I work with, and you are no exception! Thank you for your trust. I so enjoyed working together. **★★★★★ — Nina Simmons, Oct. 2024** > Great design, on schedule and on budget. Would definitely recommend CW Design for any home renovation project. She has a great eye. **Comment from CW Design, LLC:** > Thank you Nina! Despite the challenges of construction in NYC it really came together quickly and looks fantastic. I can't wait to hear about all the delicious things you are making in your new kitchen. **★★★★★ — Judy Linden, April 2024** > Cassia is a genius - the perfect mix of designer, engineer and ultimate professional. She was so fun and easy to work with. She helped us design the kitchen of our dreams - She really listened to us and got to know our style. We highly recommend! **Comment from CW Design, LLC:** > Wow thank you! It was so fun to work with you both and I just love how it all turned out. Pro photos to come! **★★★★★ — David and Ann Reisen, Dec. 2023** > Cassia guided us through a total renovation of a bathroom and kitchen. We would have been lost without her. We had a general idea of what we wanted and she helped us to refine it, guiding us around possible pitfalls. She had strong design ideas but was very responsive to our input. She guided us to excellent sources for tiling, flooring, hardware, and lighting and was sensitive to our budgetary constraints. The cabinet maker she works with was high-quality and moderate cost. She coordinated well with our contractor and oversaw the job in a way that allowed us be away from our home for two months during construction without a worry (we Zoomed weekly). The project was completed on time and within budget and we are totally satisfied with the outcome. We would recommend her to others without reservation. **Comment from CW Design, LLC:** > Thank you David and Ann. It was a pleasure to work with you both. Thank you for trusting me with your home while you were away. I'm thrilled you are enjoying your new kitchen and bath! **★★★★★ — Marguerite, Nov. 2023** > Cassia was wonderful to work with. I felt confident picking out materials with her because I knew I could trust her opinion based on her experience. She was supportive of my choices but also gave me guidance when needed. She did a lot of problem-solving behind the scenes which I was most grateful for. I now have two beautiful bathrooms and I could not have done it without her. **Comment from CW Design, LLC:** > Thank you so much! I love how they came out and the decisions you made. Enjoy! **★★★★★ — Mary Day, Nov. 2023** > Cassia was a lifesaver for us! We bought our condo knowing that the kitchen and three bathrooms would need to be gutted. This was truly a daunting prospect! I reached out to her and not only did she say that could she help us, but she also told us that she would be happy to be the point person with our general contractor! > Cassia was very good at listening to what we wanted and helping us to achieve our dreams. She was in constant communication with our contractor and dealt with lots of minutiae that would’ve been overwhelming for us! She was our advocate when any issues came up with our contractor. It was really great knowing that she was always looking out for our best interests. > Communication was always easy and responses were prompt. Cassia made a big project easy for us with really stunning results! I highly recommend her expertise and professionalism to anyone planning on a new kitchen or bathroom! **Comment from CW Design, LLC:** > Thank you so much for your kind words, Mary. I thoroughly enjoyed collaborating with you, Joe, and the entire team. May your new home bring you joy for countless years ahead. ## Selected projects - [Touch of Art Nouveau](https://www.houzz.com/hznb/projects/touch-of-art-nouveau-pj-vj~6774694) - Location: Not specified -

Thank you! A: Thank you. It's mahogany. I don't know the name of the stain. **Q: lovely cabinets** *(in Photo Questions)* Hello! What are the dimensions of the cabinet to the right of the window? Thank you! A: I’m sorry I don’t have that information. **Q: Beautiful red birch cabinets** *(in Photo Questions)* Can you kindly share the manufacturer of these red birch cabinets. Love the movement of the grain A: Hi thank you for the interest. These are custom cabinets supplied by my design company, CW Design, LLC in the Boston area. **Q: Are those stainless steel drawers part of the cooktop?** *(in Photo Questions)* I’m interested in those stainless steel drawers. Who makes them and how can I get them? A: This question was asked above as well. They are part of the custom cabinetry. **Q: Love the continuous floor to the shower...angle of drainage?** *(in Photo Questions)* We are considering a very similar construction with a continuous floor from main bath floor to shower. How did you construct the drop and what kind of drain did you use? Did you have to cut into floor joists or raise the floor? A: This configuration works best with a linear drain, which is what we have used here. Sounds like you need a good contractor! **Q: Warming Drawers?** *(in Photo Questions)* Very unique. Are these warming drawers or storage drawers? A: Hi thanks for your question. Those a stainless steel-front storage cabinets. The ovens are elsewhere. --- *Source: Houzz professional profile.
