Warren Design is a full-service firm committed to providing excellence in custom residential designs. Projects range from remodels and additions to new custom homes. The key to a successful project is our team-oriented approach that starts with the client, whether you be an owner-builder or a large developer.

With over 20 years of experience we have created a talented team of consultants, engineers and contractors who are dedicated to make sure that your project is a success. Our goal is to make your dream become a reality. The design process includes using the latest technology to design your project in 3d and BIM allowing us to show you exactly how it will look.
We only do residential design. By not doing commercial work this allows us to be an expert with residential design, building codes and the government approval process. This is important because for commercial you use completely different codes, consultants and even contractors. 

I started in the industry doing construction as a teenager. This gives me a strong knowledge of how buildings are constructed. While designing a house this allows me the ability to figure out how the house can most effectively be built from the ground up. 
“When I’m working on a problem, I never think about beauty, but when I’m finished if the solution is not beautiful I know it’s wrong.” R. Buckminster Fuller

**★ — kenkre, Nov. 2025**

> I rarely leave negative reviews, but my experience with this architect has been very disappointing. It has been over two months since I I signed the contract and paid the initial deposit. Despite multiple follow-ups via text and email, I have still not received any architectural drawings or meaningful progress updates. Communication has been slow and inconsistent; timelines were not adhered to, and I had to constantly chase updates. This lack of professionalism is not acceptable. I strongly recommend considering other professionals. Avoid at all costsI rarely leave negative reviews, but my experience with this architect has been very disappointing.

**★★★★★ — Kevin McDonnell, Jan. 2023**

> I needed some one that could create drawings and navigate through the building permit process. Not only did Warren design get the job done but they got it done quickly. They have great communication, answered all my questions and got the job finished. They made changes to the original plan listened to what I told them and made the changes with out any problems. They took on my very small project  and gave it the priority of a larger project.
> I would recommend them to anyone in need of a great architect.

**★★★★★ — Enrico Guanabacoa, June 2019**

> Planning and Design on Architectural Masterpieces. Daniel Warren has drawn and designed 6 houses for our group.  He is diligent and goes above and beyond. We are proud to call this Fine Architect a Member of our Team.

**★★★★★ — Design Studio -Teri Koss, Dec. 2017**

> I am working with Daniel on several spec homes in Silicon Valley. Daniel is great to work and collaborate with. He is extremely professional, creative, and timely. He is very much a team player and I look forward to working on many more projects with Daniel.

**★★★★★ — David Herrera, Dec. 2017**

> Daniel has been an outstanding architect for us! He always goes above and beyond expectations and provides great insight into the projects through his years of experience and variety of projects that he has successfully completed. He is a huge asset to our team and we look forward to continued business with him!

**★★★★★ — Melissa Haugh, Dec. 2017**

> I'm a realtor that works with a developer. Warren Design has been wonderful to work with.  Daniel truly thinks outside of the box when designing a home; coming up with concepts and ideas we would not have thought of!  He's very collaborative as well which is important to the team.

**★★★★★ — Jan McMahon Interiors, Dec. 2017**

> As a interior designer, I have collaborated with Daniel as well as contractors and clients on many projects over the years. Daniel is easy to work, a good listener and his genuine interest in design is reflected in his work. He comes up with a great building design and works well with both the city planning and building departments. He is available for on-site construction consultation and is always a team player looking for the solution. I have referred Daniel many times over the years and will continue to do so.

**★★★★★ — Chris Fenton, May 2017**

> I hired Daniel on a recommendation from my Contractor. We were adding on and extending the family room area. I was very pleased with the communication, plans and entire process. Highly recommended.

**★★★★★ — scott mendez, April 2017**

> I had a great experience creating a house plan to fit my lot. Daniel had many great ideas to help create a floor plan that made sense
