"The remodeling of my guest bath went very smoothly. I had few ideas as to what I wanted, but thanks to Nathan's design help, I was able to select the items that fit my concept. Many reviews talk mainly about the job and the results, but there is one important area that is often neglected: the working crew. Without exception his guys, besides being highly competent, were both respectful and considerate at all times. I strongly recommend this company!"

"Working with A. was hands down one of the best decisions I made for my remodel. From our first meeting, they really listened to what I wanted and brought ideas to the table that I hadn’t even considered. They found the perfect balance between style and functionality, making my home not just beautiful but also incredibly livable. Throughout the process, they were easy to communicate with, super responsive, and always on top of things. Remodeling can be stressful, but they made it as smooth as possible. The attention to detail was next level—I kept noticing little thoughtful touches even after the project was done. I couldn’t be happier with how everything turned out. Andi was friendly and helpful. If you’re looking for an architect who genuinely cares about their work and their clients, A. is the way to go. Highly recommend!"

"Structural engineer came by to confirm if wall was non-load bearing as suspected. Confirmed, can now move on with my project."

"My residential construction project was abruptly put on hold when a city inspector required a survey to verify the property boundaries. Unfortunately good surveyors are in high demand (at least 4 weeks out), and Voorheis and Voorheis was no exception. However, after discussing my job with Jeff, he thought he'd be able to work it in very soon between other clients. Jeff patiently answered my questions, and I ultimately felt confident to hire them for the survey. I was really happy with their thoroughness and professionalism, and ultimately the city inspector was satisfied and approved our setbacks. Thanks to Voorheis and Voorheis for getting my project quickly back on track with their excellent and timely work!"

"Office personnel knowledgeable and patient and professional and courteous. The Engineers' who arrived at my thank you. Very professional and explained all questions I asked thoroughly. Great job. Will recommend."

"The architect was professional, knowledgeable, and responsive throughout the project. Communication was clear, questions were addressed promptly, and the design met our needs and expectations. Their attention to detail, understanding of code requirements"

"I've had the recent good fortune to work with Tolga on renovation projects in Los Angeles and Manhattan Beach for which I am the Architect. The success of renovation work relies heavily on collaborative and creative structural engineering in order to realize interior and exterior architecture goals. Tolga instinctively understood my design goals and in a very professional manner he crafted solutions to bring them to reality. Many thanks Tolga. I look forward to our next collaboration."

"I recently hired G&L Design Building and Landscape for a major outdoor project, and I couldn't be more thrilled with the results! From start to finish, the experience was seamless, professional, and truly impressive. Dror, the owner, is a visionary. His attention to detail, creativity, and commitment to quality were evident in every phase of the project. He took the time to understand my vision and brought it to life even better than I imagined. His team built a stunning retaining wall, installed lush, vibrant turf, and laid down beautiful interlocking pavers that completely transformed the space. On top of that, they planted an incredible selection of trees and flowers that added the perfect finishing touch—absolutely breathtaking! The crew was punctual, respectful, and worked with great care and precision. It’s rare to find a team so dedicated and passionate about their craft. If you're looking for top-tier landscaping and design, look no further than G&L Design. Dror and his team are the real deal—professional, talented, and a pleasure to work with. Highly recommended!"
