The design team “have been huge supporters from the very start, and they bring a wealth of knowledge and experience to every project we've collaborated on. Working with Katherine closely for several months on a commercial remodeling project allowed for gaining insight into effective contractor negotiations and communication, and the level of professional, organizational and technical skills they bring are invaluable. Katherine is my go-to person for help on any design/ build projects.”

I hired Katherine to redesign my home and I really appreciated that she took the time to really understand the style that I like, even when I wasn’t even sure of what I liked initially! With her help, I feel that I ended up with a design I really love which is really me … She’s very communicative, patient, reliable and all around a great person to work with. She is also knowledgeable about a wide variety of design styles and isn’t limited to only designing what she likes, she’ll take into consideration what you like and recommend according to your preference instead of your own. Would love to work with her again in the future!

“I’d be happy to recommend Loden Design for restaurant and hospitality projects. They’ve assisted multiple tenant clients and a landlord client of mine with fit plans, layout concepts, and mood boards, and they consistently deliver thoughtful, high-quality work at a very fair price point. What stands out is their ability to balance creativity with practicality.Their designs are visually compelling while still understanding the operational realities of restaurant spaces, permitting constraints, and leasing considerations… They communicate well, move efficiently… I would confidently recommend them to landlords, restaurateurs, brokers, and anyone needing strong hospitality-focused design support”

“Katherine has great instincts and a wonderful eye for a cohesive project. In our case it was an en-suite bathroom from off the primary bedroom. I was especially appreciative of her lack of ego in the project. She really listened and took our preferences to heart. If we didn’t favor something then she listened, understood and offered up a wonderful alternative option.”
