Without people, architecture is empty buildings.
It’s how we experience architecture that matters.
Every design begins with a story.
Let us tell YOUR story.
Cinda K. Lester & Henri LamBeau, partners 12/12 Architects

Who We Are

Cinda K Lester and her husband Henri LamBeau met in architecture school at the University of Idaho, where they both received a Bachelor of Architecture (B.Arch). Cinda received a Master of Urban Planning and Policy (M.UPP) at the University of Illinois at Chicago.


Cinda and Henri live in a 1964 split-level - always under construction! - in Downers Grove with their teen children Cooper and Kellar, and their lovable mutt Bella.

Cinda and Henri began 12/12 Architects & Planners LLC with one small project 18 years ago. Since then, the size and scope of our projects have grown - everything from front porches to new custom homes. Working in our own back yard to all over the northern Illinois and southern Wisconsin area - we're still growing, and happily so.


Our one-on-one design approach caters to you; and to that end, every single project is a custom design. We work with you to design the best possible places for you and your family – often creating solutions you might not have considered.


Big design ideas are great, but so are the little ones. How you and your family are going to use the space is vital to the overall design - more than just about the floors and walls. When you say that you desperately need more storage for the kids' toys, we understand. When you say that you can't stand your dining room for one more holiday get-together, we know what you mean. We can help.

Words from Our Happy Clients

From the beginning Cinda listened to us describe or need to design an addition to our home that would support multi generational living. It all starts with really listening, which allowed Cinda to design the prefect sized space we felt would support my aging mother in our home. Her collaborative style and understanding of the technical aspects yielded a perfect design. Additionally, she was readily available for feedback and to answer any questions our GC had regarding the plans during the bid process and afterward. I have to say I really value all of the time and effort she put into our project. It's a solid piece of architecture and the neighbors all say it blends really well with the...
