We specialize in residential and commercial projects of all scales including interior remodels, additions, and new construction. While we are primarily focused on modern design, we firmly believe that successful architecture is achieved through the creation of functional space regardless of applied aesthetics. We are committed to sustainability. By taking advantage of the Southern California climate through design, the overall energy consumption of a home can be dramatically reduced. Using recycled and renewable building materials can reduce the impact of construction on the environment.

I liked that they were upfront with prices and stuck with the estimated timeline for designs and revisions. **★★★★★ — John Arthur, Sept. 2021** > Erin LeMaster was so patient with us as we asked her to make many changes to the drawings for our addition to our house and a renovation of our kitchen. She tweaked it several times to match our vision (which wasn't always very clearly explained to her since we had no clue about the whole process!). The design we ended up with we were all excited about as it matched both what we could afford to spend and our desire for a new kitchen and master suite. We definitely recommend LeMaster Architects. **★★★★★ — Phil Spencer, Nov. 2020** > My wife and I worked with Erin and Braden for 2 years to develop and construct a significant addition to our home. They proved to be very thoughtful and patient as we vetted numerous ideas. They were extremely helpful in brainstorming and developing alternate layouts. > > Our local governing plan check department was an absolute mess, having just turned on their new digital submittal process. Left to my own device, we would still be trying to get permits! Braden pushed the plans through, to his credit with amazing tolerance for government ineptitude. > > Issues during construction were addressed quickly and thoroughly. Did not slow us down at all. > > We both feel that the end product is fantastic. > > I would highly recommend LeMaster Architects to anyone, without reservation. **★★★★★ — mindymich, Oct. 2020** > We had a great experience with Erin! She was proactive, full of ideas and knowledge, and very comfortable dealing with county. The contractor she recommended was incredible, and we feel so grateful that they worked so well, as a team, too. As always, there are obstacles when renovating, but getting through them was calm and professional. I’d highly recommend LeMaster Architects; especially for the ease and enjoyment of the design experience, as well as excellent communication and organization. **★★★★★ — Justin Crow, Oct. 2019** > I couldn't be happier with LeMaster Architects. I dealt with Erin directly and from start to finish she was kind, courteous and professional. She didn't push her ideas or desires on us but wasn't afraid to share her opinions about things. I really felt that her goal was to provide us with what WE wanted and not something she wanted. There is no ego here. Great service, prompt responses and a quality product. I will be hiring again for all my design/architecture needs. **★★★★★ — User, July 2019** > We hired LeMaster Architects to design a complete remodel of a 1900 sq. ft. home. They had innovative ideas to open up the interior space and maximize storage area. Their attention to detail brought character to the house. Erin and Braden were very easy to work with and dealt with our contractor to keep our vision. We would highly recommend their services. **★★★★★ — raopriya, Sept. 2018** > The LeMasters were extremely knowledgeable, professional, and there to guide and help us through a very long and detailed home renovation project. Apart from providing sound architectural guidance, they helped liase with our Contractor on all issues - engineering, architectural, City related and design aesthetics related. They provided us with vendor names , helped us with all our material selections and went above and beyond to create an end product that more than met and exceeded our expectations - a very beautifully renovated home! Thank you LeMasters for all your help! **★★★★★ — Sandy Diaz, Dec. 2017** > We're just wrapping up our whole house remodel and it has been a pleasure working with LeMaster Architects! We found this firm to be knowledgeable, professional, incredibly responsive, and very creative. They were so helpful in every aspect of the project -- from the beginning schematic/design phase to helping to select the final finishes they provided support, feedback and any kind of advice we asked of them. We're thrilled with the end result and could not have asked for a better experience! **Comment from LeMaster Architects:** > Sandy, > Thank you for the opportunity to help you throughout this process. It was a pleasure to work with you, too. We are also happy with the results and are glad to hear things turned out to your satisfaction. > Sincerely, > Erin and Braden **★★★★★ — Rick Morehouse, May 2017** > When we decided to begin the extensive remodeling of our home, we did not realize that we would have to contact more than ten architects before finally finding one who was compatible to our goals and also affordable and available. We had an immediate connection with Erin LeMaster and she became our architect and guiding light. Basically, we were asking her to turn a 1970s house into an up-to-date “Dream House”. > > We believe our remodel was so successful due to Erin’s many excellent qualities, beginning with her Bachelor of Architecture degree from the University of Southern California, AIA, LEED accreditation and many years of experience. She listened to our long “wish list” of ideas and quickly understood what we wanted and began educating and guiding us toward a home that really fits us and our needs. We admired how well she worked with us – an active couple in our late 70s with a conservative Midwestern background. She was also very patient with us as we became acquainted with new materials and with current ways of construction. We appreciated her sensitivity to our budget limitations and were amazed at her ability to find and select lovely items of good quality that appealed to our “champagne tastes” but didn’t cost an arm and a leg. > > Erin is professional but at the same time, easy to talk to and willing to explain concepts – frequently making quick sketches. She was generous with her time, often meeting us at businesses to educate and aid us in our selection process. She was always on time and did a good job of juggling her career, marriage, family life and being a parent. We witnessed Erin’s leadership abilities when she negotiated several code issues with City Hall and stood up to the Structural Engineering firm when they made a mistake. She worked hard for us and spent extra time making everything happen, but her upfront, original project fee never changed. > > Reviewing our original “wish list”, we are ecstatic at how many items are now in our home. Our house is beautiful and uniquely ours but still blends in with the neighborhood. We would hire her all over again with no hesitation. **Comment from LeMaster Architects:** > Rick and Nancy - thank you for the kind words. It was such a pleasure working with you on your "dream house". We are thrilled that you are happy with the final outcome. **★★★★★ — Sina Ghaboussi, May 2017** > When we decided to take on our home remodel we looked to hire an architect first. We wanted someone to help us design our home, help us find a contractor and providing checks and balances for all the work being done. After interviewing a few architects we choose the LeMasters based on their professionalism, prompt response to all our questions and thorough break down of the cost of their services. We had a good idea of what we wanted done for our home and the LeMasters helped bring our vision to reality. We choose to pay extra and have them help us find products for our home. They helped us with everything from choosing our fixtures, to giving us guidelines for appropriate sizing for our chandeliers to recommending someone for our custom blinds and curtains. We have now done 2 of 3 phases of our home with them and are very pleased with their services. We will definitely be using them for the 3rd and final phase of our house. We strongly recommend the LeMaster Architects. **Comment from LeMaster Architects:** > Thank you, Sina and Carmen. We really enjoyed working with you on this project and are looking forward to the next phase. **★★★★★ — Jennifer Hudson, Oct. 2016** > LeMaster Architects coordinated our entire exterior remodel with professionalism. They had great design ideas and ways to make the project more cost-effective and yet still maintain the aesthetic that we wanted. We would highly recommend them. **★★★★ — Sharon Kemmer, Aug. 2015** > Great beginning plan for a great job. The design advise for our older building was especially valuable. We are remodeling a rental apartment kitchen in a l927 Monterey Spanish building which had been previously remodeled in the l980s with poor results. We are restoring the building and trying to use materials and designs that will undo portions of the building that were poorly remodeled in the l980s. Lowered ceilings, over-sized windows, cheap cabinets, all are being removed and re -imagined. This kitchen was literally falling off the walls and had about 17" of counter space. Our new design will re-open the kitchen to the living room, restore an ocean view from the kitchen, and eliminate the separate breakfast nook to give more space for a better kitchen. We are also down-sizing the windows to allow for more upper cabinets. The architects gave us numerous options for the arrangement of cabinets and appliances and helped us to start the project with an approved plan and a list of materials. We especially need them as the building codes have changed since 1927 and opening a bearing wall and shoring up an old building is not a simple task. ## Selected projects - [Treehouse](https://www.houzz.com/hznb/projects/treehouse-pj-vj~6709260) - Location: Santa Ana, CA - Photos: 14 - Description: The design process for this farmhouse style addition, nicknamed "The Treehouse" by its owners, took approximately 5 years and went through several renditions before arriving at its ultimate form. Having previously engaged another architect for the project, the owners were keen to not repeat the same mistakes and were intimately involved in the design process. The images seen here represent the result of a meticulous collaborative effort between client and architect. - [Brentwood Remodel](https://www.houzz.com/hznb/projects/brentwood-remodel-pj-vj~6588235) - Location: Santa Ana, CA - Photos: 8 - Description: The focus of this 1957 ranch home remodel was to enlarge the kitchen and open it up to the living spaces. Coordinating with the interior designer homeowner, the finishes selected used warm and neutral tones accented with black and gold. Highlights of the finished spaces include a walk-in pantry, built-in banquette, and fully integrated appliances with custom cabinetry. - [Sapele House Remodel](https://www.houzz.com/hznb/projects/sapele-house-remodel-pj-vj~1847372) - Location: Santa Ana, CA - Photos: 11 - Description: This project consisted of a complete systems upgrade and public space remodel of a 1970s ranch style house in North Tustin, CA. The objective was to strip the house of its dated aesthetic and transform it into a functional, modern oasis. Inspired by the owners’ recent travels to Hawai’i and French Polynesia, it was decided that the house would be a perfect canvas to explore a tropical theme combined with the simplicity of modern design. To that end, tropical details and warm materials were incor… - [Royal Grove Remodel](https://www.houzz.com/hznb/projects/royal-grove-remodel-pj-vj~5807694) - Location: Huntington Beach, CA - Photos: 5 - Description: Constructed in the late 90s, this Lennar tract-home was segmented so that it felt dark and cramped. Opening up the kitchen and dining rooms required adding steel beams and cutting the post-tension slab, however the end result justified the extra structural modifications. A large central island provides casual seating for family and guests, while custom white cabinetry and Neolith countertops complete this spacious and functional kitchen. Folding glass doors connect the new great room to the pool… - [Meads Remodel](https://www.houzz.com/hznb/projects/meads-remodel-pj-vj~2481032) - Location: Orange, CA - Photos: 7 - Description: This project started as a small remodel but quickly evolved into a down-to-the-studs renovation of the entire house. Previous additions had resulted in awkward and disjointed spaces that were cramped and inefficient. Re-engineering and removal of dropped beams and columns allowed the family room, kitchen and dining room to be combined into a great room that is bright and open. The roof was re-framed to address existing structural issues and allow for high vaulted ceilings. Carefully planned stor… - [Peninsula House - New Construction](https://www.houzz.com/hznb/projects/peninsula-house-new-construction-pj-vj~384010) - Location: Long Beach, CA - Photos: 15 - Description: The concept for this single family residence hinges on the relationship between three intersecting volumes and a base. The primary volume consists of an exterior cladding system that wraps the south elevation. Two secondary volumes are inserted to focus views and highlight significant programmatic elements. The balcony and family room are combined into a singular volume at the front of the house. The third triple height volume bisects the house and contains the vertical circulation, acting as a… - [Summit House Remodel and Addition](https://www.houzz.com/hznb/projects/summit-house-remodel-and-addition-pj-vj~730831) - Location: Santa Ana, CA - Photos: 7 - Description: The objective in updating this 1965 ranch was to combine the two existing living rooms and kitchen into one large space, raise the ceilings, and push out the back of the home while still maintaining the exterior aesthetic of the original house. A four-section tray ceiling adds definition to the new living space, while folding doors provide a connection from the indoors to the panoramic view. The highlight of the master bathroom is the custom Japanese ofuro tub, completely sunken into the floor. - [Sea Terrace](https://www.houzz.com/hznb/projects/sea-terrace-pj-vj~2306212) - Location: Newport Beach, CA - Photos: 11 - Description: Tile becomes art in this updated master bedroom and bathroom suite. For this project, the client wanted to open up the outdated glass shower and confining bathroom configuration to create a luxurious spa retreat. We began with unique wall-to-wall tile in an open shower, which came to define the color palette and mood for the rest of the space. Additionally, we removed walls, added closet space, and selected a freestanding tub. The adjoining master bedroom complements the bathroom with added blue… - [Barrett Lane Remodel and Addition](https://www.houzz.com/hznb/projects/barrett-lane-remodel-and-addition-pj-vj~1514685) - Location: Santa Ana, CA - Photos: 3 - [Rogene Remodel](https://www.houzz.com/hznb/projects/rogene-remodel-pj-vj~86813) - Location: Long Beach, CA - Photos: 6 - Description: Previous additions and modifications to this house had resulted in a disjointed layout and inefficient use of space. The goal of this project was to remedy these inadequacies and also update the systems and finishes throughout the house. The kitchen was opened up to the living room by incorporating a pass-through bar. In the rear bedroom, a walk-in closet was added and the bathroom was enlarged in order to create a true master suite. - [Greene Remodel](https://www.houzz.com/hznb/projects/greene-remodel-pj-vj~86815) - Location: Los Angeles, CA - Photos: 6 - Description: The focus of this remodel was to increase the functionality and sustainability of living space, both interior and exterior. By removing walls, the previously isolated kitchen was enlarged and connected to the living room. Formaldehyde-free custom cabinets, quartz countertops and refinished wood floors reflect the owners' environmental consciousness. The existing lawn was removed and replaced with decomposed granite and drought tolerant plants to create a low maintenance landscape. - [Corvallis Remodel](https://www.houzz.com/hznb/projects/corvallis-remodel-pj-vj~86817) - Location: Corvallis, OR - Photos: 5 - Description: This house, owned by an avid gardener, is located on a large lot in a small residential neighborhood. Initially, the owner wanted to increase the square footage by expanding into the back yard. The decision was ultimately made to focus on maximizing the existing space instead. By rearranging walls and incorporating built-in storage throughout, the desired functionality was achieved without sacrificing outdoor space.
