Meet H Design: Your Trusted Partner & Local Home Designer
At H Design, we believe that a great home begins with plans built for the real world.
Founded in 2019 by Cosme Hernandez, our firm was established to solve a critical issue in the industry: months-long waiting times imposed by traditional design and architect firms. We stepped in to capture the market of homeowners, builders, and investors who need high-quality, precise residential plans delivered in faster timelines.
Today, we have evolved into a premium residential design firm with a dedicated team of professionals and an expansive footprint covering major regions across California and Washington, including Visalia, Los Angeles, Seattle, Wenatchee, and Moses Lake.
We partner with developers to navigate complex land use consulting and streamline the rigorous regulatory process of creating new lots. By combining our expertise in zoning codes with practical site planning, we help accelerate your project timeline and maximize your property’s development potential.

Professional Collaborations
We stay at the forefront of regional building standards and maintain deep connections with local engineers, land surveyors, and permitting agencies to ensure seamless project execution.

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, everyday perfecting our craft, knowledge in industry practices and being the best 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 competitor, 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.
