2M Architecture has provided architectural and planning services throughout Northern California. We are dedicated to creating beautiful, sustainable projects in which our clients love to live.

Partners in work and in life, Marc Lindsell and Mark Tetrault merged their firms and talents together in 2005 to form 2M Architecture. Their clients benefit from their joyful, synergistic inter-play, fusing their refined sense of architecture and design with a deep knowledge of engineering/technology and aesthetic experience.

We love a good challenge! It could be an unusual site (like a lot with steep slopes, cherished trees, landscape or views) or building (like a narrow shape or non-standard structure) or a specific need or request from the client that really makes us think.  When we have interesting clients and tough design challenges, we always do our most exciting work! When working with one such couple on a significant remodel of their home, the challenge was put succinctly: “We engaged you in order to have you design a sculpture that we can live in.”

What Our Clients Have to Say

We found Marc Lindsell while interviewing 4 architects who all came highly recommended. When Marc left our house after his interview, my husband turned to me and said “He’s going to be hard to beat.” He really shone so much brighter than the others right from the start. Marc is patient, calm, and a problem-solver. We highly recommend him.”


We wanted something different in Palo Alto. We had a small project, but wanted something more unique than recent designs I had seen. This was the firm to work with! They created a wonderful living space — addition and remodel — within an older 1949 house to accommodate our kids turning into teens, but within the confines of our smaller budget. They came up with multiple designs and we ended up adding an additional family room and remodeling the living areas, including the kitchen. Marc and Mark not only came up with great ideas for the limited space, but helped us with design choices as well. They were great communicators and worked very well with our contractor, making sure we got what we wanted and needed. I’m very grateful for many choices that they urged me to make, which is hard because you can’t predict how you will use the space (glass doors to the family room, with a unique sizing that works PERFECTLY). Their design brought more light into the house as well and combined all the spaces into a cohesive living space.”


The architects at 2M, Mark Tetrault and Marc Lindsell, are extremely competent and easy to work with. It is a piece of cake to get on the same page with them because their end goal is a happy and satisfied client. They have done various projects with us, including a super complicated modern stair addition, and a lower addition. Each project has come out exactly as the client hoped. On top of this they are easy to contact and to coordinate with on plan questions and they show up at the job site at the drop of a hat. Thank you for your excellent works and we look forward to doing more projects together!”


It is hard to decide which was the best part of hiring Mark and Marc (otherwise known Mark and Marc, or the Marckitects (Markcitects? Marchitects?) as the architect for our major kitchen-plus-a-few-other-things remodel. Was it how easy and fun they were to work with, or their keen knowledge and style sensibilities, or their perceptive communications skills, or was it the lovely end result: a seamless kitchen/rest-of-downstairs integration about which we would change nothing? I guess I would have to say that it is the end-product — a well-thought-out and managed renovation that has increased our enjoyment of our home tremendously. I have wholeheartedly recommended them to friends.”


We have been blessed to work with 2M Architecture more than once and always look forward to new projects involving these two talented architects! Mark and Marc offer the truest of true Professional Services — both being true to their professional abilities, but also being able to excel at their mastered skills, while never forgetting the essential balance of structural integrity and supreme aesthetic appeal and finish! This dynamic duo offer the gentle yin and yang EVERY project needs but so many projects don’t receive.

With Mark and Marc aboard — we can count on professional transparency, clear communication, professional demeanor, timeless style, and a classy presentation of their abilities, with sensitivities to diversity in cultural architecture! There are not many Architects that define the old-school role with a twist of modern flare — but Mark and Marc have mastered achieving this beautifully!

We truly don’t know of a better team and hope to work with them both, whenever a project comes to the table!”


Outstanding design and great to work with. We’d definitely use 2M again.”


All you (really) need to know: these talented guys are wonderful and you will be thrilled beyond words! They listen, understand, digest, recommend, and collaborate. This resulted in top quality design solutions, and coupled with expert guidance and evaluation of the designs, lead to a very successful outcome. They respond to questions and issues in the most timely way, showing passion and commitment to every detail. They exact the same high standards of the contractor during the construction process as they do during the design phases. The renovation has brought me much joy and satisfaction, and knowing that I will work with them again in the future, makes it so easy to recommend them so highly!”


I trained as an architect though I have never fully practiced. For my family’s own home and kitchen renovation, we chose 2M Architecture (whom we affectionately call The Marchitects). We found Marc and Mark after passing by their small office and seeing the intriguing collection of project-related artifacts in the window…. They listen. They observe and question. Then they begin to define space with an elegance and practicality that addresses the clients’ concerns and wishes while adding an esthetic that may not have been at all obvious before. Look simply at the diversity of their portfolio. The thread there is the imprint of the client, guided by the sure hand of two consummate professionals who offer a wide breadth of capability in all building-related disciplines. Ironically, they do control, but in a way that is a check and balance on other vendors on the project. These are great fellows to work with. Could not recommend more highly.”
