She is personable, loaded with personality, talented, has impeccable taste, highly skilled, and never at a loss for ideas or options to suit your taste!! She has helped me select paint and fabric colors with a sharp eye for the subtleties, and has also been sensitive to my tastes, which are not always so daring. I now have beautiful hand-made, high quality draperies in my family room due to Julia's suggestions & effort, all made in a local factory including the custom iron rods and hardware. She has improved several of our windows with sleek custom solar shades that reveal our view as well as hand-crafted custom shutters with added unique design detail, all made by local shops, helping the local people and economy. Julia is an amazing professional as well, super timely and will go way out of her way to help you and understand your needs. Recently, I reached out to her for a rushed wood floor installation and she helped me make the color/texture selection and most importantly - get it installed with the best orientation. Without her, I would installed it orientated "the other way"-- instead of a mundane look, consultation with Julia has resulted in a very classy finished room which I am thrilled with. On our own, while intentions might be good, we often make the wrong decisions or take the advice of an installer with different motivations or overall experience. Consultation with a designer -- especially Julia --will avoid those errors, and help you make the optimal selections & decisions, giving you more enjoyment of the finished result and enhancing your investment. Julia will inspire your imagination and revitalize your energy for your home. She is truly a kind and amazing person and a gifted designer!! I can't thank her enough and I highly recommend her!! **Comment from Julia Diamond, Interior Design Studio:** > Dearest Victoria, > Thank you so very much for your kind words & professional review & recommendation! Your home was always beautiful, now it’s gorgeous & customized! You are an amazing Mom, professional woman, neighbor and valued client (and now friend). > Bless you and your beautiful family **★★★★★ — HU-818414098, Nov. 2019** > Julia is a smart, cost conscious, kind, intuitive designer who listened to what I wanted to feel in each space and came up with beautiful ideas. She was able to work with some of the pieces that I already had which was awesome. I highly recommend Julia and her team - professional, accessible, detailed and always on time. **★★★★★ — Debbi debbiberlin@gmail.com, Oct. 2019** > I have worked with many designers, both for my own home as well as for rental apartments but this is the first time I have ever felt compelled to post a review. Julia is just that GREAT! She really listens to what I want, makes brilliant suggestions when I'm unsure and is extremely professional, responsive, talented, caring (I always feel like she is just as invested as I am and goes out of her way to ensure I will love the final results), as well as honorable and fun.. I also love how I can give her a theme or show her a space and she will recommend options, which i would have never even thought to consider and yet the final results were incredible....far better than anything I could have envisioned. If you are looking for the best of the best and someone you can trust as both a designer and a human being -- Julia is the one. **Comment from Julia Diamond, Interior Design Studio:** > Thank you so much Debbi! You are an absolute pleasure to work with and you (and your beautiful baby daughters) honestly just make our day! **★★★★★ — Deborah Chang, Jan. 2018** > I have used Julia since first moving to California over ten years ago and have stuck to her like glue. She has the best eye for beauty and detail and we have created "masterpieces" throughout the state and I even flew her over 3,000 miles (one way) to do my house in Florida. Some of my rooms are on her pages here. The key to her success: her knowledge of the best fabrics and materials bar none in the world, the people who work with her, and her artistic creativity and inspiration. Plus - she is open to collaboration and redoing work to get it perfect. From bedrooms to offices, to custom furniture, to salons and dining rooms, and kitchens -- and garage gyms -- she has done it all!!! **★★★★★ — Wendy Gardner, Aug. 2017** > Julia and I have known each other for many many years from another industry. When she went into design, I consulted her on a small project in my former home. Her work was totally inspirational! > > Now in a new condo, she has again helped me to realize my perfect home. Her vision is fresh and she is not afraid to mix eclectic styles together-- of which I have several... > > I could not think of a more consummate professional for my interior design needs. **Comment from Julia Diamond, Interior Design Studio:** > Thank you so much Wendy. Those wonderful eclectic parts are what make it wonderful you! Enjoy your new adventures and PNW retreat and have a coffee for me. **★★★★★ — David Rees, March 2017** > What a wonderful person to work with. She knows her stuff and is not bashful in letting you know her opinion. She worked with us on picking carpets, wall coverings, paint and shutters for our windows. We get a lot of "wows" when people come in the front door. She even had some ideas on certain areas of the outside of the house to paint contrasting colors. **★★★★★ — Edie Fasano, March 2017** > I am a retired architect and I have had the pleasure of working with Julia on several projects, including renovations to my own home. Julia consistently impresses me with her professionalism, knowledge, design abilities and her tireless efforts to ensure her clients receive the best possible service. **★★★★★ — Danielle Baker, Sept. 2016** > I can't say enough good things about Julia. She is hands down the best in the business. She is so passionate about interior design and always gives her absolute best to her clients. I love working with her so much. She really listens to her clients and delivers the most unique and creative ideas. She also has the best easy-going personality and is a hoot to work with. **★★★★★ — Joe Carballosa, Sept. 2016** > Julia Diamond is a professional and a true pleasure to work with. Her clients benefit from thorough attention to detail. Julia really cares about doing the best job possible and her design talent allows her to accomplish that. I would recommend Julia to anyone looking for an outstanding designer! **Comment from Julia Diamond, Interior Design Studio:** > and Joe of Modern Rug Designs is one of our key vendors!! Absolutely outstanding work, impeccable client service (and installation!), you guys make us look like champs on both coasts. Thank you Joe (and William Swan) **★★★★ — Angela Amerson, Aug. 2016** > Julia is a professional interior designer with experience in creating and designing beautiful rooms and window treatments. She has a good eye for colors and presents her ideas in a format that is easy to understand what the end result will be. I would recommend her for a consultation on large design projects and window treatments for an entire home. **Comment from Julia Diamond, Interior Design Studio:** > Thank you Angela!! You are one of my most valuable & beloved vendors as well! > Robert Allen (and all of its affiliates) and Beacon Hill continue to be some of my most loved (and requested) textile suppliers and vendors! No matter what I throw at you guys; you seem to always come through for us! Even years later when I come back to an old clients' home or business, my Robert Allen fabrics still look great, stand the test of time and still look phenomenally vogue 6, 7+ years later...and counting. > I love working with your entire team at the Los Angeles Robert Allen Showroom and feel proud to call you my supplier, colleague and associate(s)! Thanks for always making us look good, we just simply couldn't do it without you. **★★★★★ — Clarified Studios, Aug. 2016** > Julia is an incredibly talented interior designer and an absolute pleasure to work with. She has an incredible eye and impeccable taste that makes any space truly one-of-a-kind. She is also incredibly funny, sweet, and a blast to be around. I would jump at the chance to work with her again! ## Selected projects - [Mandalay Beach Family Retreat](https://www.houzz.com/hznb/projects/mandalay-beach-family-retreat-pj-vj~5960848) - Location: Oxnard, CA - Photos: 6 - [Wood Ranch Renovation with Special Needs Accessibility](https://www.houzz.com/hznb/projects/wood-ranch-renovation-with-special-needs-accessibility-pj-vj~1640916) - Location: Wood Ranch, CA - Photos: 8 - [LA Loft](https://www.houzz.com/hznb/projects/la-loft-pj-vj~271284) - Location: Marina Del Rey, CA - Photos: 3 - [Outdoor Living In Lake Sherwood](https://www.houzz.com/hznb/projects/outdoor-living-in-lake-sherwood-pj-vj~1112181) - Location: Thousand Oaks, CA - Photos: 3 - [Luxe Townhome By-The-Sea](https://www.houzz.com/hznb/projects/luxe-townhome-by-the-sea-pj-vj~505704) - Location: Not specified - Photos: 1 - [Sycamore Estate](https://www.houzz.com/hznb/projects/sycamore-estate-pj-vj~1563318) - Location: Not specified - Photos: 7 - [Outdoor Living](https://www.houzz.com/hznb/projects/outdoor-living-pj-vj~1572690) - Location: Not specified - Photos: 1 - [500-Book Library](https://www.houzz.com/hznb/projects/500-book-library-pj-vj~1563356) - Location: Not specified - Photos: 1 - [Magnolia Plantations, FL](https://www.houzz.com/hznb/projects/magnolia-plantations-fl-pj-vj~1109521) - Location: Not specified - Photos: 4 - [Sherman Oaks Residence](https://www.houzz.com/hznb/projects/sherman-oaks-residence-pj-vj~1563341) - Location: Los Angeles, CA - Photos: 3 - [Home Office by the Sea](https://www.houzz.com/hznb/projects/home-office-by-the-sea-pj-vj~1563369) - Location: Not specified - Photos: 1 - [Santa Rosa Estate](https://www.houzz.com/hznb/projects/santa-rosa-estate-pj-vj~1563350) - Location: Not specified - Photos: 7 - [Dealership (Automotive) Executive Office](https://www.houzz.com/hznb/projects/dealership-automotive-executive-office-pj-vj~271281) - Location: Ventura, CA - Photos: 2 - Description: Building renovation, executive offices add-on (new build) - [Stafford Estate](https://www.houzz.com/hznb/projects/stafford-estate-pj-vj~1563339) - Location: Not specified - Photos: 4 - [Electrolux Kitchen Contest](https://www.houzz.com/hznb/projects/electrolux-kitchen-contest-pj-vj~1112165) - Location: Not specified - Photos: 1 - [Rustic Modern Retreat Lakeside](https://www.houzz.com/hznb/projects/rustic-modern-retreat-lakeside-pj-vj~2628960) - Location: Seattle, WA - Photos: 7 - Description: This beautiful renovation was a complex and most-transformative construction project I have ever been a part of. We were able to literally tear the roof of, reconstruct a new roofline and interior ceiling height, while changing and refacing all of the existing old rotting cedar shingle siding. We adapted new smooth concrete panel siding, with charcoal steel roofing and all new windows, window sliders, doors all around and new Trex decking and the place went from scary to chic, tear down to custo… [See all 16 projects](https://www.houzz.com/professionals/interior-designers-and-decorators/julia-diamond-interior-design-studio-pfvwus-pf~403093683) ## Community Q&A **Q: doesn't the brass tarnish?** *(in Product Questions)* A: gorgeous!!!! the patina will be beautiful in years to come **Q: Love the rug!** *(in Photo Questions)* Can you tell me where you purchased the rug and who the manufacturer is? A: Hand-knotted, natural wool rug from Nourisan. **Q: Need suggestions as to color of laminate flooring** *(in Design Dilemma)* We are planning to repaint out living-room/dining -room - 11' wide x 25' long. We have decided to replace the flooring first. It will butt against laminate tiles that are on the rest of that floor of the house - the front hall and kitchen. Because we have so much oak that can be seen from this room, can I go dark with flooring in the lr/dr? The room is only 7'8" high. I'm planning to paint a taupe/gray .Will dark flooring make it look shorter? Shall I choose a wide or narrow plank to make the room look wider? A: Don't do it! Laminate flooring is terrible and does not increase the value of your home! Especially for a kitchen! If you must do it, save it for a home office or study. --- *Source: Houzz professional profile.
