“My husband and I own a four unit apartment building in the Beverlywood area of Los Angeles that was constructed in the '40's. It was originally one of the "Co-op Style" buildings similar to the condos of today. Due to extenuating circumstances, it has been extremely difficult to update the building. HHDesign, with confidence and poise came to our rescue. Their professionalism and architectural expertise have turned a nightmare into a sweet dream. We were so impressed with their portfolio which is largely high-end and contemporary. This could have possibly been a stumbling block, however; you can imagine how pleased we were when, at their suggestion, they maintained the integrity of the building and style of the neighborhood. Even better yet, while honoring our budgetary constraints, they managed to give the building and grounds an incredibly needed facelift and artfully pulled the exterior facade into the 21st Century. We have had numerous complements from neighbors and friends and now have pride of ownership thanks to the tireless efforts and extraordinary service afforded by HHDesign. It is with the utmost sincerity that we recommend this highly efficient and talented team to the consumers of Houzz.”
GCC Designs
Building Designers in Simi Valley, CA
Average rating: 5 out of 5 stars17 July 2017
“As a real estate broker, property manager and investment property owner for over 15 years I have worked with may designers, contractors and sub contractors (Good and bad) Mark at GCC Designs is at the top of my list of professionals I can trust to do the job right the first time. He shows up on time, articulates the scope of the job in a way that is easily understood and executes on time. The value he provides is right in line with the cost of the job. He is currently working on a major job in my personal home that is moving along just as planned.”

“They did a great job with our remodel and new ADU project. Loved the new look! Very professional, and very communicative. Happy to recommend them for architectural plans and the structural work. We had them manage our project too and led the extra scrutiny they had on the budgets and timeline management.”
JZ Plans DESIGN
Building Designers in Simi Valley, CA
Average rating: 5 out of 5 stars12 June 2023
“It has been an absolutely pleasure working with Justin! No hassle, no drama and no hidden cost! My job entailed architectural plans for a major renovation; removing walls, adding an opening for an extra large sliding door and the addition of an ensuite bathroom. Justin came to my house to discuss my project and take measurements, this took him ~ 2 hours. He told me when the plans/drawings would be ready and the cost. The cost, I thought was very fair indeed. I received the plans/drawings by the scheduled date. After the plans were done, however, I wanted to make some changes to them, Justin told me upfront how much it would cost to do so and how long it will take him to make the changes and as before, I received the plans by the scheduled date. During the process, any questions I had Justin responded by text usually within 15 to 30 mins and by email by that day. He also Zoomed me to explain something that just was not clear to me on the plans. Via Zoom, he was able to share his screen and point out on the plans/drawings what he was referring to and explain in layman's terms for me to understand better. I submitted the plans to the City and they had one question. Justin responded to the question immediately and updated the plans accordingly at no cost to me. I resubmitted the updated plans to the City and they passed. I would recommend Justin and I would certainly use him again.”
Willisland Design Works
Building Designers in Simi Valley, CA
Average rating: 5 out of 5 stars28 May 2017
“I hired Willis Daniels and Willisland Design to complete the redesign, expansion, and remodeling of 5 houses for re-sale. The results were extraordinary. I believe that the homes sold for significantly more than market and more than other projects in the area due to Willis' excellent ability to collaborate and his incredible design sensibility. I have hired him on many additional projects and have seen his work for others. HIRE WILLIS! He is passionate about his success, yes, but he is also passionate about yours. Willis is a great human and great designer.”

“Kaveh was a huge asset for me with a large tear down project in Newport Beach. He went above and beyond to make sure that everything went smoothly and was done correctly. My contractor also really enjoyed working with him and mentioned that his plans were highly detailed which led to fast approvals from the building department. My contractor now uses him for other projects. Kaveh is extremely responsive, diligent, and trustworthy. I highly recommend!”

How to find the right building designer in Simi Valley, CA for your build or renovation


As with all other professional services for home design and renovation, the best way to choose a building designer is to assess their past work against the style and requirements you have for your individual project.Most states don’t have specific registration processes for building designers, so it’s best that your search is based on past work and referrals. Some industry bodies or professional associations, such as the Building Designers Association of Victoria (BDAV), offer a list of members, which you can check against bodies such as the Victorian Building Authority (VBA), to gauge their type of work and any registration numbers.

Once you have a shortlist of building designers, engage in face-to-face talks about your brief, to ensure you’re on the same page.
