We worked with Steve Sigler and his Team of highly skilled Architects to design our Dream Home, not to be built in California, but in the Great State of Texas!
The Team sat down with us, put all of our thoughts and ideas on paper, and then went to work to design the Perfect House for us, they asked all the right questions, and listened, yep listened...what a concept! 
After a couple rough draft layouts, they were right on track designing our house. The design of the house was perfect, and their ability to enhance every detail, exceeded our expectations! Josh has an incredible skill for taking your thoughts and ideas, to a level you never dreamed of! Now, your plans are finished, you think you are done, and ready to build your house.....And then Josh pulls out his magic....
Axis 3 has an incredible, state of-the-art Virtual 3D Architectural program that brings your Project to life! He had us walking through our Dream Home, looking out the windows, seeing how the texture on the walls look, watching the sun rise and set throughout the rooms in the house! We could walk around the outside of the house in the day or night! simply incredible....pretty damn cool!
I could go on and on...but to keep it short and sweet, these guys are skilled way beyond the norm, a real pleasure to work with, and I highly recommend them. 
P.S. When we showed our plans to our Builder in Texas, they were blown away, said they have never seen plans with so much thought and detail! They kinda made me look good too! ....Thanks Axis 3!

You’ve bought a lot to build your dream house, but now you are not sure how to make your dream a reality. Axis 3 Architects will turn your dream into a technological vision using their architectural skills, experience and the latest computer visualization tools, giving you the confidence to take the leap and follow your dream. Stephen, Jason, and Josh developed our floor plan and turned it into a 3D rendering that we were able to walk through with Virtual Reality googles before a shovel was lifted. It was truly amazing!

Temecula Wine Country

We began the design of our new home in Temecula Wine District with an Inspiration Board (see photo) that communicated a visual "dream home and dream property". Fortunately, Stephan, from Axis 3 Architects drove by our little 2 Acre lot everyday on his way to work. Our paths finally crossed once I found him on "houzz". We came to an agreement that Axis 3 would help us convert our inspiration to a house plan that could make our dreams come true. Little did we know that we were going to go through a process which we have never experienced, although we have built other homes.

The first thing Stephen asked us to do was walk out to the middle of our lot and Stephen had us turn a full 360 degree circle and we told him which views we loved, which ones we liked and which ones we would rather avoid. This helped Stephen roughly layout the placement of the house on the property and begin the arrangements of the rooms within the house.
The second activity was to have Stephen design the floor plan based on how we wanted to "live" in the house. What "view" from the Kitchen; from the Master Bedroom, etc. After many meetings we finally found the design that fit our needs. With other projects, this is when the architect begins the tedious work involved in making the plans that a contractor can use to build the home. Not Stephen and Jason.

The next activity stunned us. Jason took the floor plan and created a 3-D picture of what our house was going to look like when it was finished. You have to see this to believe it. 
This was a valued-added service that made it so much easier for us to visualize our home. 

I want to jump to the end of the process. After months of design, making changes, changing our minds on the design, a lot of very personal back and forth with Stephan and Jason, our plan was submitted to Riverside County and only required very minor corrections after their review. This is the signature of their service. They are careful, complete and professional. 
Now that we are actually building the house, our contractor has been able to "build" the house from Stephan's plan with minimal clarifications. Once the house is completed I will add a completed photo so everyone can see how close it is to the original 3-D version.

We bought a property in Temecula. We hired Stephen to work on the plans for our new home. As of today, I have to say that our experience has been GREAT!! Their professionalism and expertise has made all of this worth while. Its taking a little longer that we expected but I truly don’t mind because I can see and feel that they want us to be truly happy with the outcome. We are very close to completing the plans and cant wait for construction to begin.



Stephen is great to work with. He is quiet when you first start the process. But I found he was studying my house, me, and my husband to try to understand our needs and tastes. He worked well with change orders. My contractors loved him. My husband and I could not be happier with the outcome. The kitchen and great room remodel is awesome. When we needed to tighten the budget he came up with cost saving options for us.

Teresa Schutt


I am a general contractor who has had the opportunity to work with Stephen and his son Jason many times. I have found them to be very professional and incredibly talented architects. Every project has its design challenges and the Siglers are masters at turning those problems into assets. I look forward to working with them in the future and I can strongly recommend them for your

MILLER Architectural Corporation


I have know Steven Sigler for over 30 years and regard him as a friend and talented architect. He is honest, reliable, creative and a skilled professional. You would be well served to have Axis 3 Architects as your design team.

David Beever

Temecula, CA

Axis 3 Architects started my project by sitting in lawn chairs on a 5 acre lot, looking at the views. Stephen incorporated the all of our ideas and then designed one of the most beautiful homes you can imagine - with 360 degree views, the largest garage ever, a master bedroom wing and guest bedroom wing in the house - which makes it great for guests to come and stay. Excellent design process and attention to design detail. Thank you Stephen and Jason.

Michael Kearns

Canyon Lake, CA

I hired Stephen and Jason to design a custom high-end home for me in the Canyon Lake area. This was my first time developing a property from the ground-up and, aside from their design services, which were fantastic, I was struck by their professionalism in helping me through the rather daunting process of building something from scratch. They clearly had a wealth of experience from which to draw, providing excellent feedback and advice throughout the entire process.

The home that they designed ended up as a beautiful contemporary/modern design perfectly situated to the strengths and features of the site and the surrounding neighborhood. It took great advantage of the unique topography and views. Ultimately, I would highly recommend Axis 3 to anybody needing architectural services. Five stars.

Erin Moore

Cherry Valley, CA

I contacted Stephen to design our custom estate in Cherry Valley, CA and from our initial meeting we knew he was the professional with the ability to translate our vision into reality. The design interview he conducted with us that determined our priorities in a home and the views we wanted take advantage of from each room was creative and insightful. After we had decided on layout that he designed specifically for our property we are beyond eager to move from schematic design into the 3D phase. Looking forward to our future meetings to really see this project take shape into the Mediterranean inspired home my husband and I have dreamed about for years. Thank you Stephen and Axis 3 Architecture!


Temecula, CA

Stephen and Jason of Axis3 have / are doing a great job in helping us design and providing a 3D Presentation of an Addition to our house. They have been very helpful and gone above and beyond and my expectations. Can't wait to see the final outcome!

Christopher Coglianese

Oceanside, CA

I retained Stephen Sigler/Axis 3 Architects to design a custom home I had built in coastal Oceanside a few years back. I had a clear vision of what I wanted, and Stephen not only executed on it, but improved it. From the first day that we went to the site and he questioned, suggested, but mostly listened, to the last few tweaks before the plans were finalized, the process was a pleasure; and Stephen's enthusiasm seemed to mirror my own. The end product is, in my opinion and the opinion of many passers-by who have offered their compliments, a truly beautiful home. Moreover, having lived in it for some 5-6 years now, there isn't a change that I would make to the interior flow and layout. It maximizes the space while maintaining a consistent and attractive aesthetic. In short, there's nothing I would have done differently about this project, including hiring Axis 3 Architects.

Stephen Sigler and his team were extremely professional, very helpful and responsive to all our questions and inquiries. I had used Axis 3 Architects on a previous project and would not hesitate to use them again.


Temecula Valley Wine Country - Temecula, CA

My wife and I purchased property in Southern California's Temecula Wine Country a few years ago and last year we began searching for an architect who was not only actively working in our area, but one who could share our vision of creating a Tuscan style home that would maximize all the incredible views our challenging hillside property had to offer. After meeting with Stephen we knew we found the right Architect for us. Stephen is a knowledgeable, patient, and very personable professional. After a few months of "old school" pen & pencil design collaboration we arrived at the basic floor plan for our dream house. At that point Stephen introduced us to his son, Jason (also an Architect), who transferred our floor plan to CAD and proceeded with adding all the details, including developing 3-D images of what the house will ultimately look like on our property! Working closely with Stephen and Jason throughout the past year has proven to be an exciting, synergistic process. At this time we are nearing design completion and are preparing to submit final design for Plan Check. 

While I not only highly recommend Axis 3 Architects to anyone else looking for a competent architectural firm in the Temecula/Riverside County area, in the case of my wife and I - we believe we have two new friends in Stephen and Jason.

Brian Friesen

This firm is great to work with! I'd definitely recommend giving them a call!

Ryan Rogers

Temecula, CA

I have worked with Axis 3 Architects on several projects. As a builder, I would highly recommend them. Their design and cutting edge technology of 3D renderings are the best. As well as their incredible eye for design. They truly take the time with both, client and builder to bring projects to a reality. You won't be disappointed!

The Axis 3 Architects Design Philosophy

Our firm employs and promotes creative and realistic solutions based upon the following:

  • It is our intent and primary focus to service the needs of our clients with respect to functional, creative and aesthetic design needs and requirements with realistic project scope, budget and schedule.
  • Through the continual advancement of architectural practices, it is our intent to incorporate the latest “state of the art” 3D imagery technology to create and compose our architectural projects.
  • By implementing 3D design technology, it allows the design process to best serve the client’s needs to better understand, view and critique design requirements and progress during the various design phases.
  • We encourage the development of sustainable technology methods such as “green” architecture.
  • We provide complete and accurate architectural, electrical, mechanical, and plumbing documents to enhance the approval process by the local planning and building department review and approval agencies, and reduce the risk of potential changes during construction.
  • We believe that city and county jurisdictional requirements are intended to enhance our communities regarding safety and health. Thus, it is our intent as architects to understand and comply with all ordinances, planning and building department requirements and to assist our clients in successfully navigating these mandates to obtain appropriate approvals for construction of each project.
  • It is our primary goal to achieve the most practical and appealing result for each client needs.

The Process

The following provides an overview of the sequence of activities of a typical project:

Step One

First informal meeting with the Architect

Step Two

Choosing an Architect

Step Three

Schematic Design

Step Four

Design Development

Step Five

Construction Documents

Axis 3 Architects, PC

Step One

  • Once an Owner has determined the potential need of an architect, a “no fee” initial meeting at the proposed site or existing facility is scheduled between the Owner and Architect to fully comprehend the characteristics of the project, scope, preliminary budget, feasibility and overall intent of the Owner.
  • Site considerations will be discussed including size and configuration of property, existing elements such as buildings, trees/rocks, topography, possible future building orientation, site grading potential, soil conditions and existing soil reports and the need of a civil engineer if grading of the site is anticipated.

Note, if the terrain of the site is not flat and has moderate to severe slope, a topography of the existing land will be required to fully analyze the appropriate design options.

  • Existing or required utilities that may require percolation studies for future septic systems, sewer availability, access to all utilities such as water, gas, and electric service.
  • Primary topics include basic owner requirements of the proposed home and garage, access to the proposed building location, possible easements and restrictions such as CCR`s or Home Owner Association
  • Overall design process and schedule including overall fee structure regarding architect, engineer and civil engineer as required. An overview of architectural services and defining the tasks and scope of the project, including local jurisdiction reviewing agency requirements.
  • An opportunity to meet in person (Owner and Architect) to better understand each other’s desires, goals and determine the design team compatibility.
  • Note, the initial site meeting between the owner and architect is not intended to be a “sales pitch with contract in hand”, but rather an informal gathering to provide to the owner valuable information regarding the site which is being considered, the overall process of design, preliminary budget and schedule and the selection of an architect who is best suited for the Owner`s needs. Once the “site walk” has been completed, the architect selection process can commence at a time best suited by the owner.

Step Two

Pre-Design – (Program):

Prior to the actual design of the project, various factors will need to be gathered by the Owner and Architect. This information relates to the proposed scope of the project, which includes site requirements, (on and offsite) utilities, roadway access, topographical data, property size and location, and any legal property constraints, and will also include specific information relating to the proposed building size, use and function.

Choosing and meeting the architect at “Second Meeting”

Based upon the information gathered from the “initial site walk” between the owner and architect, the owner may then proceed with the selection of the preferred architect at which time a second meeting is scheduled. This meeting is called the “Design Questionnaire Meeting” and includes a list of questions that encompasses approximately four to six-hours of discussions at the owner’s home and at the chosen site. The meeting entail a “step by step” process regarding owner specific functional needs of the overall design of the residence.

It is very important to understand that no floor plans are required at this meeting, instead the discussions are centered upon the functionality and flow of each of the spaces required, sizes of each space, adjacency requirements, including exterior and interior view orientation and prioritization. The Design Questionnaire is intended to seek valuable information directly from the owner and is documented by the Architect as “Pre-Design” data that will be later utilized to formulate not one but various floor plan versions for any given site condition.

Step Three

Once the design questionnaire data has been gathered, the architect will then proceed with producing three to four floor plan options that will be presented to the owner as the initial “Schematic” floor plan suggestions.

The Architect commences the initial design with the development of the schematic or preliminary floor plans with the intent to discover “various” options that may be possible. This process is for refining the options to a preferred floor plan that satisfies all basic design considerations. In addition to floor plan layout, the architect will also provide a preliminary roof plan reflecting the desired floor plan and a schematic site plan indicating the approximate position and orientation of the proposed residence. At this juncture, the overall floor plan has been developed indicating the gross square footage of living area, possible patios and or decks, garage areas, room sizes and locations, including windows and doors and kitchen layout. Upon the approval by the owner these items, the design process is then ready to proceed to the next phase. At this juncture, the initial “Design Fee” and services have been completed based upon a flat fee agreement.

Design Development.

This following phases is also established as a “Flat Fee” based upon the overall design and scope of the project, that includes all architectural, electrical, mechanical, and plumbing drawings, energy calculations, structural engineering design and submittal to local building authorities and Home Owner Associations, if applicable.

Step Four

 Upon successfully completing the initial design phase, the Design Team, with Owner participation, defines and develops the (3D) three-dimensional modeling of site configuration and proposed floor plan/building indicating the overall shape, configuration, color and characteristics of the project. The development and refinement of the visual “3D” animated “fly by and walk thru” will further assist the Owner`s awareness and understanding of the scope and details of the Project prior to construction.

As the design is developed, various aspects of the project utilizing “3D” modeling can be viewed, upon request by the Owner, via Axis3Architects PC. Dropbox and in office presentations. Owner response and comments can be accomplished by e-mail, phone or at the Architect office. The process allows convenient dialog, ease of design flexibility and changes as needed for design compliance during this phase. As the 3D modeling progresses, the architect will meet with owner to review and discuss its development of the computer-generated floor plan and obtain recommended changes as required to satisfy the overall design intent. The goal is to provide to the owner a well-defined “model” of the proposed project, (house and site), that can be easily understood visually by all participants from any perspective. Once the 3D modeling has been completed and approved, the architectural services can proceed into the “Construction Document” phase.

Step Five

This phase provides the backbone of “technical” drawings that include the communication between Owner, Architect and “Consultants”, i.e. structural, mechanical, electrical, special systems, landscape and civil engineering, representing the drawings that is required by the local planning and or building and safety department authorities to obtain building construction permit.

These documents include various detailed drawings that represent such items as site plan, floor plans, elevations, roof plan, reflected ceiling plans, building sections, structural foundation and framing plans, details, and mechanical, electrical and plumbing and energy efficiency required data. It is our intent to ensure design satisfaction and understanding of the Project by way of discussions and visual interaction during the development and completion of the “construction documents”. We also encourage general contractor involvement and possible selection during the design phase of the project to better establish a realistic probable cost of construction well before the completion of this phase.

It is our belief that if an Owner obtains a better understanding of the design process through visual interpretations, fewer changes may occur during construction thus saving significant time, money and aggravation due to change orders requested while under construction.

Quality Assurance – QA

During the Construction Document Phase, an “in house” plan check review of the construction documents will be performed for quality assurance. All recommendations and corrections issued by the local building and planning department are incorporated into the documents to ensure compliance to all local and State code requirements. It is our intent to provide complete and accurate documents, and have experienced “first hand” that it has a direct impact upon accurate and timely bid responses and bid results.

Jurisdictional Approval

As with each City or County jurisdictional review agency, the intent is to protect the public with respect to structural integrity, including fire and life safety. Therefore, it is the responsibility and commitment of the Design Team to ensure that all required construction documents meet current code requirements.

It is our desire to fully cooperate with each jurisdiction that has review/approval authority over each project. As each project is reviewed by the local building jurisdiction for approval for construction, we provide complete and accurate information for purposes of properly executing the construction of your project. This “review and approval process” is accomplished in concert with the Owners participation. It is the Architects responsibility to act as the liaison between the Owner and reviewing agency to successfully obtain the necessary approval documents.

Bidding Services: As Additional Services upon request by the Owner

Axis 3 Architects may provide consultation to the Owner and coordinate the bidding process between the Owner and General Contractors. This service includes pre-bid meetings and job site walk with General Contractors and Owner. In addition, our office may provide, upon the request of the Owner, distribution of all contract documents to interested bidders, including obtaining bid documents for final review and selection.

During the bid phase, the Architect may formally accept questions from the bidders to formally clarify or answer questions relating to the bid documents for construction.

Upon receiving bids, the Architect may provide the Owner with consultation in reviewing the bids and verify as to the scope of work described by the contract documents. The Architect may assist the Owner in selecting the General Contractor, and assist in preparation of bonds, insurance, and funding requirements as needed.

Construction Administration Services

Axis 3 Architects may provide services during construction including review of the work performed by the General Contractor for conformance to the approved contract documents, as additional services as requested by the Owner

Through the years of witnessing and studying the completion of our projects, it has been found that our most successful accomplishments in architecture have been realized by following each of these steps of the Design Process. Our goal is to create architecture that we can be proud of and enrich the lives of our clients and the community in which we choose to build, develop and live.
