My husband and I hired Mark to design our home restroom addition and Mark exceeded all expectations. He knew exactly what to ask to understand our vision and provided valuable advice during the process. As new home owners we truly appreciated the expertise he was able to provide. After design, Mark submitted all plans to the City and they were approved much quicker than expected. Mark is very professional, and responded promptly to every communication. Thank you Mark for making our design experience such a great one! **★★★★★ — Todd Gilbert, July 2023** > My wife and I looked long and hard for a designer for the ambitious home addition and remodel we started planning several years ago before we finally found Mark Greenwald and GCC Designs, but we sure are glad we did. > > Mark was a pleasure to work with at every step along the way. He always brought a great deal of courtesy and professionalism to the process of redesigning our home. He did what he said he would do, had lots of great ideas, and listened carefully to us to make sure he understood our needs. His pricing was always fair, and there were never any nasty surprises. > > There was a lot of back and forth, which is normal, before we got our new floor plan just right, but we couldn’t be more happy with the way it turned out. Once we locked the plan, Mark sent the drawings to his engineer, and before you knew it we were ready to submit for plan check and permitting. In our case, the plans had to go to the city and then the county. The city permit tech told me he’d never seen better plans for an initial submittal, and he approved them right away. The county asked for some minor tweaks, which Mark took care of quickly, and as soon as we submitted those, they were also approved. > > Now we’re in the middle of the addition/remodel, and it’s wonderful to see the plan coming to life. We hope to post a follow up when we have before and after photos available, which should be some time in 2024. We highly recommend Mark Greenwald and GCC Designs. You couldn’t be in better hands. **★★★★★ — DCHA Interior Design, July 2023** > Alchemy Designs Inc recently collaborated on a full remodel project in Huntington Beach with GCC Designs. > Mark exemplifies professionalism, integrity, reliability and knowledge in every aspect of his work. > From start to finish, his commitment to delivering exceptional service in a timely matter was evident. > We truly enjoyed working with him and would highly recommend his services. **★★★★★ — Edward Gilmore, Feb. 2023** > Mark led me through a difficult time when I didn’t know where to begin after my home was destroyed by fire and smoke damage. Hey patiently answered all my questions and continues to do so, as rebuilding is nearing completion. I highly recommend Mark I will definitely call him if I ever need architectural services again! **Comment from GCC Designs:** > Great client. So many contractors tried to take advantage of the insurance situation or omitting work from the scope. I just protected his interests as well as getting plans through the City. **★★★★★ — barneybjones, Oct. 2022** > Mark was referred to us by a friend who had used GCC for a garage addition. Mark designed a wonderful ADU that made the best use of our limited space. He was even able to fit in a pantry and full sized appliances. We found Mark to be easy to work with, a good communicator and a pleasant person. We plan on using Mark’s skills for a project in the near future. **Comment from GCC Designs:** > Great client to work with! It was a pleasure working with them. **★★★★★ — Kathie Sadeghian, Aug. 2022** > Mark was awesome and helped and walked us through everything highly recommended - helped us with every step dealing with permits and the city. **Comment from GCC Designs:** > Great clients to work with! It was a pleasure working with them. **★★★★★ — HU-324008294, July 2022** > Mark/GCC helped walk us through our first major renovation after being in our home for 17+ years. He patiently listened and made recommendations to ensure the final plans addressed our lifestyle and consistently shared less expensive alternative solutions to mitigate our ultimate costs. We would highly recommend Mark and GCC! **★★★★★ — HU-784562585, April 2022** > Mark has helped us with 3 projects now; a garage rebuild, remodeling a living area, and adding a second floor to the house. He always has more than one idea for solving the inevitable building issues that come up, which I believe comes from his years of practical experience. He is someone you can trust and rely on. **★★★★★ — HU-492824324, Feb. 2022** > We found Mark on referral. Great experience. Mark has strong character & integrity. He is an expert at what he does. And Mark's experience really pays off, saving time & money on your project. Do yourself a favor and call Mark. **★★★★★ — rorysheehan, Dec. 2021** > Very satisfied with GCC! > Quality & well thought out work all within a very reasonable timeframe. > Will definitely use him again when the need arises. **★★★★★ — Stephania, Aug. 2021** > Mark was incredible when it came to our home design. We had a full renovation plus an addition to our home. Mark was patient and helpful even when we had a major design change from a two story addition to a one story addition. Mark walked us through the design process and the permit process. He also continues to check in on the job while we're in the construction phase. I would highly recommend Mark for your next project. **Comment from GCC Designs:** > Great clients - they stuck with it when they had to change scope and size. **★★★★★ — HU-105251805, July 2021** > I've always have used Mark as my contractor and he has transitioned to doing Design / Plans etc. so in my current remodel I used him again to create the detailed plans for use by my new contractor as well as plans required for permits. > > I know Mark has done a lot of work as a contractor and in the city and he knew exactly what was needed and my plans were approved straight away ... in this time of COVID the last thing you want is for your plans to go back and forth with the city with the known delays. > > Mark did a great job!! ## Selected projects - [Rzo ADA House Huntington Beach](https://www.houzz.com/hznb/projects/rzo-ada-house-huntington-beach-pj-vj~7243468) - Location: Huntington Beach, CA - Photos: 40 - [Torrance Whole House](https://www.houzz.com/hznb/projects/torrance-whole-house-pj-vj~6514504) - Location: Torrance, CA - Photos: 14 - [BB Huntington Beach CA](https://www.houzz.com/hznb/projects/bb-huntington-beach-ca-pj-vj~7145774) - Location: Huntington Beach, CA - Photos: 12 - [Pdn 2-story ADU](https://www.houzz.com/hznb/projects/pdn-2-story-adu-pj-vj~7243453) - Location: Long Beach, CA - Photos: 13 - [Mllr Whole House Remodel/Add](https://www.houzz.com/hznb/projects/mllr-whole-house-remodel-add-pj-vj~7243484) - Location: Long Beach, CA - Photos: 8 - [EV Rossmoor](https://www.houzz.com/hznb/projects/ev-rossmoor-pj-vj~6519252) - Location: Rossmoor, CA - Photos: 20 - Description: Tear down garage in back, open up backyard space, put garage in front with connection to enter house, add bedrooms, expand kitchen and add great family room, front porch and back patio cover.
