I can't imagine what our house would have turned out like if we hadn't found Rouben and his team. They brought our house plans to life with their realistic renderings. They are there for you as much or as little as you would like. We came to Rouben with our house plans already almost completely drawn but needed his help when it came time to decide things like a giant wall of windows, where to place certain doors and windows, how big to make them, where to place beams in the ceilings, cabinet height, color choices, landscape layout, etc. Looking at the plans on paper just isn't enough. Rouben and his team can bring them to life so you can see exactly what you are getting and don't have to guess and regret later when it's too late. They took time to review my many Pinterest and Houzz boards to get to know my style. You do not have to imagine it -they'll show it to you. When designing the exterior of our home, I had a hard time deciding between a white or a green color of the house and brick options. Rouben and his team created multiple renderings of our house with various colors and textures so I could see exactly what each option would look like. By the time I picked the final colors, bricks, roofing material I knew exactly what it would look like and had zero doubts. Another example of how amazing their skills and service are is when we were deciding on a fireplace layout, finishes, size, placement, etc. We started with one design but had to pivot and Rouben and his team made it easier by providing renderings of what was in my head. Their final rendering was exact down to the size of our tv and fireplace so we knew exactly what size to order, etc. I just can't say enough about how valuable their service is. Rouben and his entire team are easy to work with and made each step enjoyable and exciting along the way.

It was great to work with Rouben. He got us to express our concepts of what we wanted, then took that starting point and embellished it to create our dream home. He helped us every step of the way, from textures to colors, to interior design, using 3-D mock ups in order to compare options. He worked with our contractor to be sure everything was just the way we wanted it. The result was fantastic. We get great compliments on our house every time someone comes over to see it.

Design SI is a team of professionals!!! Rouben is an extremely talented architect. He listens and communicates with us during the whole process. Always keeping our interests in their mind, they try hard to come up with designs that work for our needs within a reasonable budget. We are more than pleased with the work Rouben and his team have accomplished! Design SI is the best in town!

As a fan of modern contemporary design, I was very excited to find Rouben's business in northern California. HIs style quickly grabbed my attention. From the very beginning, Rouben and his team have gone out of their way to make me feel comfortable. We have worked on four projects together and I am consistantly impressed with their customer service and attention to detail. From design to construction, Rouben is always present to answer my questions and put my concerns at ease. I would recommend Rouben and his team to anyone who is inspired by contemporary and modern design.

Once again the team at DesignSI has knocked it out of the park! I viewed the project, this time, as fairly straightforward: frame and hang the 20 or so pieces of photography and oil canvas art that my wife and I recently purchased while vacationing in New Orleans. I knew they would do a great job, as this is the 4th or 5th project that they've helped me with over the last 4 years. Nevertheless, I was taken aback by the creativeness, attention to detail, and professionalism of their work. After initially discussing the project with Rouben, I found communication with Alyson to be timely and straightforward. She promptly addressed my queries and concerns and always had unique insights and an additional unique perspective to add. Because of my sometimes hectic schedule, after sharing my vision and ideas, I gave the team complete autonomy on the details of the project. I love how the 6 pieces placed in the stairwell share a common purplish color palate and complement the black and white table in the adjacent kitchen. I also love how they placed the photographs of the 2 cars (one old school '57 Chevy, in Havana, and one '87 Cutlass Supreme on 20" rims, in New Orleans) in the same room. The photos are on walls facing each other with a different photo on the adjoining adjacent wall. The contrast between the two beautiful cars in amazing and exactly what I had in mind when I purchased them both. I could go on about the quality and choice of framing, the price and value of their services, the perfectly placed height of the photos, or the fact that they were able to complete the project in Seal Team 6-like precision while my wife was at work (the surprise was worth it!) but I trust my sentiments are evident by now. DesignSI does a fantastic job! No matter how complex or straightforward your project appears, they approach it with a level of sophistication, creativity, and attention to detail like few others. Thanks team!

No job is too big or too little for Design SI. So I had an unusual design request: Building a treehouse! And they crushed it. I told them the idea and general layout (VERY LITTLE DIRECTION). Just the fact that I want to build a treehouse for the kids, that will go between 2 oak trees. That is all they needed. They provided a design that was easy to follow and used innovative materials like corrugated plastics for walls and roof. Also suggested use of wire instead of traditional balcony. These innovative ideas for materials saved time and money. and the end result looks GREAT. Now I am hiring them to do my actual home and I have every confidence they will do a great job.

Thanks so much for the opportunity! We loved working with you and the family!

My wife and I asked Rouben Mohiuddin and his Design SI team to design a modern style house to fit our sloping lot and maximize our lake view. Rouben knows modern design well and shared many options with us.He is very artistic and turned our simple ideas into something amazing.His final design fit the look and feel of the land well and it has the "WOW" factor. Working with Rouben,Zack and Alyson, has been an easy and fun experience.We are looking forward to working with Design SI during the construction of our dream home. We wholeheartedly recommend Rouben and his Design SI team. Lyle and Cassie Vargas

After having used Design SI for a previous project, I had them come up with a design and plan for my backyard. They presented many ideas that incorporated my vision for the project. Any changes or questions that I had, they were very receptive and responsive. They stayed within budget and finished in a timely manner. I would recommend them for any of your design needs, whether it be a building or landscaping project.

Rouben custom built a dining table for me that needed to fit the proportions of my dining space. Since the space is small but I wanted as large a table as possible, he designed the table to be as long as possible in the center and then reduced the corners to avoid bumping into sharp corners while navigating the space. This helped out tremendously. The piece is also trendy yet organic and natural. I'm delighted!
