Get matched with top architects in Altadena, CA

"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!"

"The work Erdelyi associates did is great, but communication and timeliness were lacking. I didn’t have a consistent point of contact throughout the project - it just seems my project was handed off from one person to the next with no continuity and I had to proactively reach out for updates."

"We had a great experience working with Eran. He is a professional and is an expert in his field for our specific project, he handled all the structural work for the seismic retrofit and when my architect had a melt down, he even stepped in and took on that responsibility too. He collaborated with us and we spent the time to understand our needs and where we wanted to take the project. He made our life much easier by getting the building permits and worked with the planning department and the inspectors. Invaluable. We look forward to working with him in our next phase and would recommend him for future work."

"I had the pleasure of working with Leslie Andersen on two separate projects: an ADU and a Guest House. I can't speak highly enough about the exceptional experience we had from start to finish. First and foremost, her quick response time was truly impressive. Every query was met with prompt, detailed answers, which made the entire process smooth and stress-free. It was clear that Leslie values their clients' time and prioritizes effective communication. As for the projects themselves, the results exceeded my expectations. The ADU design is both functional and aesthetically pleasing, blending seamlessly with the existing structures while adding a fresh touch. The guest house is equally crafted with attention to detail and a clear understanding of our needs and preferences. The professionalism, creativity, and efficiency displayed throughout were remarkable. I highly recommend Leslie to anyone seeking a top-notch architecture. Her commitment to excellence and client satisfaction truly sets her apart. Thank you for making our vision a reality!"

"I?m a real estate investor and I?ve used Design1 Studio for three projects now ? two ADUs and a small lot subdivision. They understand the investor mindset and don?t over-design things. They know how to maximize square footage while keeping construction costs reasonable. That?s rare."

"Smooth and professional experience. Their team is knowledgeable, efficient, and made the design and permitting process easy. They delivered exactly what I needed on time and within budget. Iâ d definitely recommend them for any architectural project."

"Thank you Pacific Sands and the entire team, work was delivered on time and having communication with the entire crew made everything much easier. Highly recommended."

"Curt is a professional who is as real as it gets. He won't lie to you and will tell you the God's honest truth; something that is ever so important when you are departing with a sizable amount of money. He will tell you realistically what you are looking at with budget things, and I cannot stress how important and appreciated that was for us. He is super professional and very good at what he does, and we are so happy to have found him!"

"This is my first time dealing with this company and I am very impressed. They are very hard working, gets the job done right and on time, PRICED VERY FAIRLY!, They donâ t complain about changes to the project when they come, and doesn't try to break your pocket for these changes. All in all they are very professional, and whether you are building or remodeling for personal use and need an architect or a licensed contractor then BuildForm Design is the way to go, I'm a professional developer and I will be using them for all my projects!"
