 Trustindex verifies that the original source of the review is Google. I had recent deck replacement done by Omar Construction. He recommended H Design. Cosme responded the same day, came out and spent a couple hours taking measurements. The permit went through fairly quickly, about two weeks. Cosme was great, very pleasant, knowledgeable and personable. He and Omar worked very well together. Also, shout out to Jorge at J-Rod Welding. He did the steel railing fabrication. Solid work by all involved in our deck construction.

 Trustindex verifies that the original source of the review is Google. Cosme and Alma are great to work with.  They helped my wife vision become a reality.  We had a difficult project as we were doing a kitchen remodel with structural engineering and an ADU that was even more complicated. But they preserved and helped us get the design she envisioned and we are already building thanks to their design and assistance.  Highly recommend H-Design for your next building project.

 Trustindex verifies that the original source of the review is Google. Cosme was a pleasure to work with. He is quick with communication as well as the work completed to update our site map for an After the Fact permit. He was also able to give us good details on the process itself. Would recommend!

 Trustindex verifies that the original source of the review is Google. H Design Co was professional, fast, communicative and knew the county’s codes well.  Their design was approved by the county shortly after submittal and did not require any back and forth.  I will use them again for future builds.

 Trustindex verifies that the original source of the review is Google. Awesome design team took over my remodel when another firm put my project on the back shelf. Cosme guided me through the whole process and responded well to both my design ideas and things we discovered about the home’s original structure. The end result was perfect, and he walked it through the permitting process. Excellent team, attitude, creativity, and service!

The H Design Advantage: Construction-First Thinking

What truly sets H Design apart from the competition is our foundational background. We don’t just design on paper; we know how materials behave and how structures are physically assembled on a job site.

Why our technical expertise matters:

We have spent years around countless residential construction projects. As your home designer, we take those real-world field insights and directly apply them to your blueprints.

This ensures that every layout we deliver is not only visually stunning but structurally functional and optimized for your builder, saving you thousands of dollars in construction materials.

Our Core Values

Our rapid scaling and 10X growth system is anchored by a simple, unyielding philosophy inherited from family traditions: Hard Work, Customer First, and Whatever it Takes.

Hard Work

We keep a high level of energy and systems to streamline workflows.
We work hard every day, perfecting our craft, gaining knowledge in industry practices, and being the best home designer we can be for our paying clients.

Whatever it Takes

In an age of instant services, we respect your timeline. We have optimized our internal workflows to deliver your construction documents faster than the competition, without ever compromising technical accuracy.

Customer First

Customer Service is our top priority. From regular communications with each client, to our client portal where each client can check in on the progress of their design and billing information.

We connect via text messages, emails, phone calls, video meeting and physical meetings at the office or at the job site, if needed.

We obsess with ensuring our clients have a positive experience through the H Design process. At the end of each project, we kindly ask for feedback through Google Review; where others can see how we treat paying customers.
