Client Testimonial

Doug Leach has designed two homes for us in Palos Verdes Estates and in both cases we could not have enjoyed a better experience. After working with Doug the first time we never even considered another architect for the second home. He listened well to our thoughts and needs and then designed homes that completely met those desires. 

Client Testimonial

Working with Doug Leach was an absolute joy for my wife Kei and I. We purchased a lot in Palos Verdes Estates on a very difficult but beautiful site with a 180-degree ocean view. Doug realized our dream by designing a stunning Frank Lloyd Wright style contemporary home that has been and is the perfect home for large scale entertaining and intimate family moments.

It was one of the very few homes that was approved on consent which meant that Mr. Leach, by being very considerate to all of our neighbors and respecting the views and compatibility of the neighborhood , did his homework.

Client Testimonial

Not only is Doug creative and talented, but working with him was truly an enjoyable experience. He really listened and was always available to answer questions or discuss ideas. Doug created a beautiful Spanish style home for us that is both authentic and unique. His expertise and professionalism were crucial in navigating our plans through the approval process. I highly recommend Doug Leach and his team.

Client Testimonial

As an interior designer/interior project manager for the past seven years, I have worked with many architects. I am constantly amazed at how seamless my own home project was because Doug was so competent and knowledgable. He has the rare combination of artistic talent and professional comprehension of the building process. He understood the aesthetic concept we were looking for, as well as the needs of our family and the confines of our property. Doug communicated exceedingly well with the Neighborhood Compatibility Committee and the Art Jury of Palos Verdes Estates, and he was able to keep in mind our budget constraints, with no surprises. His attention to detail and ability to work so well with his clients’ needs really made for a positive experience. We are, fourteen years later, still thankful for how much we love our home.

Client Testimonial

Doug is a good listener, has great ideas and is very easy to work with. He is a gifted and talented architect. His designs are both beautiful and functional. And his support staff is friendly and knowledgeable. But for us, the extraordinary value Doug provided came when we went through our city’s Planning Commission approval process. Doug’s ability to work with them and to keep our design intact was exceptional. When we were under construction, Doug was always available to consult with the contractor when questions arose. We cannot thank him enough for working with us and for providing guidance through this challenging, and at times, difficult process. If you want the best, then you have found him.

Client Testimonial

Doug and his team were great to work with and made the entire process easy and comfortable. He was very open to our ideas and worked with us to design a contemporary home with the livable floor plan we were looking for. He even reworked part of the plan when we realized much later that we wanted something different (at no charge!). Our home is almost built now and we're very excited to be moving in soon. Doug came highly recommended to us and we've been extremely pleased with our decision. In fact, we recently referred him to friends and we'd highly recommend him to anyone looking for a great architect!.
