He is a true professional and also lovely to work with. We have a large showroom and he is so great about focusing on what he wants, coming up with amazing product and material combinations, and getting things done. I always love it when he walks in the door. **★★★★★ — Jared Paul, May 2016** > Tonic Design Studio is fantastic to work with and look forward to the next project! Very Professional and Organized firm. **★★★★★ — Bjork Studio, Nov. 2015** > People think we are joking when we say that Tonic Design Studio gets the award for "Best Prepared Designer EVER," but it is actually true! This firm worked in tandem with an architect on a large house and had the complete, extremely custom interiors designed, specified and detailed - over two years BEFORE ground was ever broken on the project. Who does this? Really does this? Principal interior designer Willem Stear is brilliantly focused, detailed and exacting in all aspects of his work - which is quite stunning in its own right. His South African background and education bring a fresh and welcome spin on "modern style" to Atlanta. Willem's knowledge of modern architecture, furniture, interiors and theory is an innate love and not merely decorative. He considers function, movement and space before the first finish or piece of furniture is selected. He takes the time to understand how his clients wish to live, takes these ideas, expounds upon them, often educating in the process and quite literally broadens their horizons. Much like a set designer who researches and conjures up perfect spaces for specific characters, Tonic Design able to do this in "real life." This is a design firm that melds a love and understanding of modern into timeless, functional and handsome interiors. **★★★★★ — raydeeb, Oct. 2015** > Willem was a terrific asset in helping us design and implement our master bath. He has great vision, helped us with colors, materials, design, and overall flow. He is very detail oriented. Plus, he is a kind, respectful man who follows up with all our questions and concerns. We highly recommend him!! **★★★★★ — nawench, Oct. 2015** > Willem at Tonic Design Studio designed the decor for our master suite, downstairs powder room as well as our living and dining rooms. Throughout the process, he was utterly professional and in addition to his design work, he managed all the installations and deliveries. All we had to do was marvel at the outcome! For our living and dining rooms, Willem involved me in the design of custom carpets that he created for the spaces. That space went from a stark empty room to a classic vibrant space. We worked with a number of contractors in the remodel of our home and Willem was by far the most reliable and professional - staying on schedule and within the agreed budget. It was delightful to work with such a creative and professional person and we HIGHLY recommend Willem and Tonic Design Studio. **★★★★★ — darwinfjohnson, Oct. 2015** > Willem and his team were top notch. I couldn't have asked for a better result. Each and every time I had a question or needed anything they were right there. This was the first time I've hired a designer and it will certainly be the last. Thanks so much Willem. **★★★★★ — Poggenpohl Atlanta, Feb. 2013** > We've had the pleasure of working with Willem at Tonic and are very happy with the collaboration. Willem is a talent designer but is also a true professional. He arrives early for every appointment, keeps us informed, and is always easy and pleasant to work with. **★★★★★ — sarahk007, Nov. 2012** > My husband and I recently built our dream home. After interviewing several local designers, we discovered Tonic Design Studio. Willem Stear is an absolute gem and will soon be a force to be reckoned with! He managed to turn a very stressful time into a fun, interactive and all round great experience! Not only is he creative but also has a great business sense (my husband is an accountant - even he was impressed!). Willem never tried to force his ideas on us but rather listened to what we wanted and made it happen! I'm beyond happy ... living in my dream home! **★★★★★ — jparker056, Nov. 2012** > Working with Willem Stear from Tonic Design Studio was probably one of the best experiences I have ever had with a creative professional. He has an incredible work ethic and is always professional - far exceed my expectations! Tonic Design Studio will be my go-to for all future projects! ## Community Q&A **Q: What color is the quartz island?** *(in Photo Questions)* Love the color of the island. A: Hi - the island is a quartzite slab that we found at a local stone yard. I don't recall the exact name of it, I'm sorry. **Q: wood floors in bathroom** *(in Photo Questions)* What are the wood looking floors in the bathroom? Thanks A: The wood is not used in any 'wet area' so it's perfectly fine to use. We used marble tile in the raised wet area. **Q: Stone wall - Gorgeous!** *(in Photo Questions)* Love the shower wall! Very original - contemporary yet warm. Can you kindly tell me who makes and where I can purchase? Thank you! A: Hi Cathy. Thank you for your question. Are you referring to the marble slab on the wall or the stacked stone along the exterior wall? The slab on the wall is marble and any good fabricator will be able to hang a slab on a wall for you. The stacked stone outside is Tennessee Grey and was acquired through our building contractor - but this is something that easily available. **Q: light fixture** *(in Photo Questions)* Who makes the light fixture/chandelier over the tub? A: Hi - we had this light fixture custom made. If you're interested in something similar feel free to shoot us an email and we'll be able to give you more information. Thanks, WJS **Q: dog sculptures** *(in Photo Questions)* Where are the dog sculptures from? A: Hi . These are from Magis (Puppy). They are available in various sizes and colors. Hope that helps. **Q: where did the chaise lounge covers come from, please** *(in Photo Questions)* A: The covers where custom made. We used fabric from Donghia and had them custom fitted. We'd be happy to quote you if you're interested! --- *Source: Houzz professional profile. Reflects the profile as of 2026-08-22.*
