Designed with intention.
Built without compromise.

Designer. Builder. One Partner.

From first idea to final detail.

Your home should be entirely yours.

Not a compromise.

Not a collection of disconnected decisions.

Not something that gets lost between design and construction.

But something intentional.

Considered.

Built exactly as it was meant to be.

For most clients, the challenge isn’t vision.

It’s control.

Control over decisions.
Control over cost.
Control over how everything comes together.

You’re expected to coordinate architects, builders, consultants, and trades—
all with different priorities.

And every gap between them
creates risk.

Risk of misalignment.
Risk of costly changes.
Risk of a result that falls short.

This is where projects begin to unravel.

We do it differently.

One partner.
One vision.
One continuous process.

Design and construction
working as one from the start.

Every decision aligned.
Every detail carried through.
Every step managed with precision.

So what’s imagined
is what gets built.

The goal is simple:

Remove complexity.

Eliminate risk.

Create clarity at every step.

So what is imagined is what gets built.

And the final result feels exactly as it should.

Not forced.

Not compromised.

Inevitable.

Doron leads Spire with a singular focus: ensuring that what is designed is what gets built.

With over 30 years of experience across high-end residential and select commercial projects, his work is defined by clarity, precision, and control.

Each project is approached as a fully integrated process— aligning design and construction into one seamless path.

The goal is simple:

remove complexity, eliminate risk, and deliver a result that feels inevitable.

I’ve worked with Doron on several projects in California and have always been amazed by his creative energy. In client meetings he is constantly sketching and it’s fascinating to witness.

PAULETTE TRAINER, INTERIOR DESIGNER
I would highly recommend working with Doron of Spire Architecture. He has a great sense of style and can immediately understand what will or won't work when contemplating design concepts. In addition, he listens intently to the client so that the collaboration of ideas ends in a mutually desired result. Doron's easy going personality and passion for his work makes for a productive and harmonious experience.

TERESA CHAFFEE
I asked for exceptional architecture, spire delivered in every way.

BRANDON T. : LOS ANGELES DESIGN-BUILD
I was Project Manager on a complex high end custom home in which Doron designed. As with most custom homes there are always changes or modifications and this is where Spire really shines and works very well with homeowner, contractor and subcontractors to get exactly what the client wants. His on the job presence and knowledge of design really helps all involved to come up with ideas that further enhance the project while keeping costs in line. He is open to ideas form all involved and is a team player which makes the building experience much more pleasant. He can design/sketch multiple ideas during meetings so everyone can see the options and make an informed decision. Needless to say the project was a success and I would highly recommend Spire Architecture for any project.

STEVE MOBERG, PROJECT SUPERINTENDENT
Doron showed continued knowledge, professionalism and diligence in my interactions with him in the construction and inspection fields. He is always open to interpretation and implementation of the building codes and anxious to comply with code requirements. His hands on supervision lends to quality and expedient results.

MICHAEL D, BUILDING INSPECTOR
Doron Dreksler at Spire provided us with extensive architecture and design services for the remodel of a fine home we purchased in San Francisco, CA. The house was built on a grand scale in the early 1900s with classic high end finishes. However, this grand dame home needed some modernizing without compromising its wonderful vintage qualities. Mr. Dreksler did a wonderful job for us in achieving this goal. He was knowledgeable and creative, yet unlike some architects we have previously used, he was an excellent listener. He collaborated well. He was prompt with his work and his fees were fair. He was fresh, energetic and fun. He had an infectious positive attitude. His motto throughout the process was "stay inspired". Although this was a big, expensive and time consuming project with many challenges, he kept us inspired. We love the results. Bottom line, Mr. Dreksler and Spire were excellent.

DAVID Y, SAN FRANCISCO
I highly recommend working with Doron. He has a terrific design sense and is full of great ideas. He is also very good at understanding what you want and working with you to achieve your goals. He is professional, prompt and thorough and an all-around charming, easy to get along with guy. All of these attributes make him someone I recommend highly and I would definitely work with him again.

LISA HENSON, CLIENT
Doron Dreksler aka Spire Architecture and I worked together on numerous residences from 2000 to 2008. He designed and drew the plans and I was the General Contractor. Doron has a gift for visualizing and placing a house or addition on any property in a way that complements the site and takes advantage of the views from all directions. He was always available for consultation during construction and came up with answers to any and all questions and concerns. I highly recommend Doron. You won't be disappointed.

ESA KIRJOLA, CONTRACTOR
Doron's work on the architecture and siting of the Shannahan Residence in Granite Bay resulted in a stunning project that fully engages the natural elements of the site topography, magnificent rock outcrops, ancient oak trees and panoramic views, and set the stage for the creation of an exterior environment that allowed seamless integration of the front welcoming space and the patio entertainment areas with the interior spaces and the views from all areas of the structure. A joy to work with!

RONALD ALLISON, LANDSCAPE ARCHITECT
When we hired Doron Dreksler the name of his company was Doron Dreksler Designs. In the middle of our design/build he change his company name to SPIRE. Much more creative name for the creative architect that he is. Doron was very aware of the site and how the house, drive, shop and garage should sit and how all of these buildings should fit into the property. We have over 40 oaks on 5 acres and we were able to save all the trees. The design itself is perfect for the property. Doron is very cognizant of what will work and what will not work on a piece of property. He works hard to create the picture perfect design for the property and then delivers to build the most deliberately designed architecture for his clients. I would recommend Doron Dreksler, SPIRE Architecture to anyone who is looking to get the full benefit of their property and architecture you can be most proud of.

D & D SMITH
I am working with Doron on a single family home in Guerneville. He is creative, prompt, and honest and I would recommend him to anyone.

Pierce Cavallero
After building several homes during my life, I hired Doron (Spire Architecture) to design our retirement home in the foothills. With a 360° hilltop view and a goal to have a modern Tuscan farmhouse, Doron did a fantastic job integrating the dwelling to the landscape and exceeding our expectations. With his knowledge of period architecture and creative ideas, our home truly is “a modern Tuscan farmhouse.” We are completely satisfied with his performance and would not hesitate to recommend Spire Architecture.

LESTER BRUSATORI
We are owners and operators of an 18 room Inn in the Sierra Foothills. In 2009 we engaged Sprire Architecture to help with the complete renovation of a 100 year old building in the historic district. The project included a full restaurant build-out in the same space and new rooms on the second floor. Working with Doron from Spire he immediately processed our project priorities from both an aesthetic and economic standpoint. It took 4 years to obtain the financing and approvals for this $1M plus complete renovation, yet during this time Doron was patient with us as the design process continually evolved. Our goal was to honor the historic qualities of the building yet add a modern sophistication to the space. Spire helped us to achieve these goals and improve the overall function and flow of our building. Doron listens and respects his clients while using his visual and creative feel to improve the project. He has also worked as a general contractor so he can see the project from the construction stand point so the design has an economic reality. I plan on working with Spire again in the future and would recommend his services. robert gordon

ROBERT GORDON
We used Doron's services as an architect in 2007/2008, for what amounted to a total remodel of our home, reducing it to 2 bedrooms before re- construction began. Doron was easy to work with in the design phase, available for questions and some changes as the project continued and worked with ourselves and the contractor very well. We remain very happy with the work product we received. As an aside, but an example of the quality of the work, our home was selected for a local house tour in the year after the work was completed.

ALAN BIERCE
As a photographer I work with both architects and with builders, but these days its rare to find an architect whose also builds out his designs. Doron is unique in that respect, starting with concept and following through to see it built as imagined. I'm never there for the beginning of the process, but when I visit one of his projects to photograph it, its fascinating to have him explain the aesthetic and functional, and how they interact. Architecture is the art of spaces and building is the craft of it. Doron is both an artist and a craftsman!

DAVE ADAMS, PHOTOGRAPHER
Doron Dreksler was both the architect and general contractor for our house in Volcano, CA. He is especially gifted in designing and orienting a house that takes advantage of the best views. We were very impressed with the integrity and work ethic of his subcontractors. Both Doron and the subs were very responsive to our desires and worked very hard to finish our house on schedule. Doron is wonderful to work with. He has a positive attitude and is excited about designing and building beautiful homes.

KEN REDLER, DESIGN + BUILD CLIENT
We had a great time working with Doron and I can't imagine finding a more creative and talented person to help us in this big process.

AARON + KAREN B, DESIGN + BUILD CLIENT
I highly recommend Doron as not only a gifted designer but a true team player. BDA has teamed with Doron on both commercial and residential projects with fantastic results. Always a positive experience.
