He provided high quality deliverables and was always quick to respond to all of our questions. It was an extreme pleasure working with Allan because of his attention to detail and professionalism through the entire process.

Thank you Allan for helping us realize our dream kitchen and master bath! **★★★★★ — Leonard Gregory, Dec. 2022** > Allan Teta of TRE Architecture helped us through a very long and arduous approval process for an extensive residential remodel.

We are truly grateful to Allan and his team. **★★★★★ — HU-111325080, Feb. 2021** > TRE Architecture helped design a fantastic Spanish Revival Home for our family on and empty lot next to an existing Spanish Revival home that our family has owned since the 1920's in Oceanside, California. Allan Teta is a true professional and extremely creative and somebody I would highly recommend to design and provide all elements of architecture for a custom home. **★★★★★ — madrebt, Dec. 2020** > We met Allan, of Tre Architecture, after the interior space of our remodel had been planned, creating some unique challenges for him to solve. He rose to those challenges not with merely sufficient, but with elegant solutions. He's a skilled and talented architect who leads by example. He works hard, smart and efficiently. Allan understands and respects contractors and all the tradesmen and professionals needed to complete the job. His strong collaborative abilities helped us navigate decisions, among all those people, we might not have otherwise understood. Allan saw our project to the end and the highest praise we can give is that we would love to work with him again some day if another project arose. We consider him not just an architect, but a friend. **★★★★★ — Don Hensel, Dec. 2019** > I have found Allan to be extremely knowledgeable, competent, reliable and fair in all of my interactions with him. He has come up with excellent designs with my needs and desires in mind while at the same time being cost conscious. I would highly recommend Allan and TRE Architecture to everyone. **★★★★★ — Verde Design Group, Landscape Architects Inc., Aug. 2019** > We have worked with Allan and the team @ TRE Architecture on several projects the last few years. Allan is a talented designer, creating design solutions that are unique and appropriate to the project site and client. He creates an environment for a true collaboration between the Client, and the rest of the design team which ultimately creates a better project. The team @ TRE is thorough at coordinating the various design professionals (engineers, landscape architects etc.) , and getting the project through the approval process. When I have the opportunity, I highly recommend Allan and the TRE team and look forward to working with him on many projects in the future. **★★★★★ — Lyn Heller-Altona, Oct. 2018** > As Allan Teta of Tre architecture always says, our project is not big, but it is complicated and challenging. From day one, our remodel journey has been just that...small but complicated and challenging. And we cannot begin to imagine going through it without Allan. He has taken our dream and turned it into a viable and stunning design plan, with creativity, amazing support & guidance, grace, and wisdom. We are forever grateful that we chose to work with Allan and Tre. Absolutely recommend! **★★★★★ — Kim Lansford, Jan. 2017** > We started working with Allan Teta in 2012 on a preliminary plan for our new home after considering a number of local architects. We have been very happy working with Allan and having his father's valued input as well. A summary of Allan's strengths: Planning and listening, had a questionnaire to help us communicate and figure out what we wanted. Always listened, I can't say this enough. A real architecture/design talent, has great ideas. Attention to detail. Has an excellent network of necessary people and companies to get the various parts of the job done, builder, engineers, suppliers, etc. Allan is a superb relationship builder and peace keeper. He also either already has or will develop good relationships with those involved in the permit and utility process. Allan, as stated before, is a great listener. His caring and respectful about his clients and everyone he works with comes through constantly and consistently. Allan had a special situation in dealing with us both because we lived many states away and were doing this work remotely and because of special physical disability considerations needed to make the construction fit our needs. Allan was up to the challenge and also helped us coordinate much of the building process because of our situation. He helped us select a builder, had a questionnaire prepared for that too. Working with Allan and the builder he helped us find are keys to success in building our new home. Allan also set up and coordinated many meetings when my husband Bill would come to town to check on the progress. Many times, Allan was our eyes and ears on the building process. Allan has been and is a great part of our team in the building of our home. My own background as a financial institution executive and Bill's as a long time manager of a fortune 500 company helped us appreciate Allan's many strengths and especially where they different from some of our own strengths. I would invite Allan to share contact info with serious potential clients. **★★★★★ — Tammy Bender, Nov. 2016** > I worked with Allan Teta on a patio renovation project. He came highly recommended from our realtor. Allan was great to work with on every level...design ideas, prompt follow up, and most importantly, he recommended a great contractor to complete the project. I will definitely use him when we begin plans for our kitchen renovation in the near future. **★★★★★ — Patrick Zabrocki, Nov. 2016** > Allan and his team have created fantastic designs, provided high quality deliverables, and most importantly have been a pleasure to work with. It is a rare thing to come across a firm that I can trust will do what it takes to get the job done and also do it with integrity but I have found it with TRE Architecture. ## Selected projects - [El Camino Del Norte Residence](https://www.houzz.com/hznb/projects/el-camino-del-norte-residence-pj-vj~7851941) - Location: Not specified - Photos: 7 - Description: Situated on a gently sloping site in the heart of the Rancho Santa Fe Covenant, the El Camino del Norte Residence takes cues from the structural clarity and purposeful simplicity of California's mid-century modern architecture.
