Because home is more than a place
- it's a feeling -
Why “Affinity”?
-
Affinity means connection — the natural, effortless kind.
-
We believe that the best residential spaces feel like an extension of the people who live in them.
-
That’s why we design with empathy at the core — creating environments that are thoughtful, comfortable, and aligned with your values.
-
Affinity Residential Design was founded on a simple belief that good design starts with understanding people.

What People Are Saying
Kristin has worked diligently with me over the last two years, creating an incredibly detailed floor plan and elevations, sourcing other good locally based professionals to assist with the permit process, etc. Kristin is reliable, responsive, good natured, capable, professional, and endlessly willing to make whatever changes I wanted without any objections or loss of interest in the project; she is upfront about her fees, only charges for work she does and doesn't pretend it took more hours than it really did, and for all of those reasons, I recommend using Kristin's design services highly.
-Jody C, Client
Kristin has become an integral part of our development team in Pebble Beach and Carmel for a myriad of reasons; her creativity in devising design solutions that adapt to City requirements, her ability to create a cooperative relationship with City and County Building & Safety departments, her efficiency in turning around plan designs and her conscientious and cheerful demeanor through all of it makes Kristin invaluable to us. And...Kristin's "value engineering" expertise also helps keep our projects on time and on budget. Need I say more?
-Nick S, Client
Kristin Setliff has been wonderful to work with. We have given her name to several clients for multiple types of projects and she has adeptly guided them through the design and permit process. She is responsive and educated when it comes to her field of work. As a contractor having a teammate in a project is a requirement and she always goes the extra mile to ensure that all parties are given accurate information to complete a well-executed home.
-Mallery M, Contractor
Kristin Setliff is truly one of the greatest designers I’ve had the pleasure to work with. She has been one of my mainstay designers on many of the projects I’ve completed over the years. Her talent, professionalism, and attention to detail are unmatched. I’ve trusted her not only with my clients’ projects but also with design work on my own home.
-Tony S, Contractor
As an engineer, I have really enjoyed working with Kristin on projects. She is attentive to her clients’ needs while maintaining a common-sense approach to her design. The solution-based methodology she uses achieves a productive balance between engineer and architect. Add a positive attitude and she is an asset in my book. I look forward to working with Kristin in the future.

You can’t find a better designer in the Monterey Peninsula or anywhere for that matter! Her work on residential projects is second to none. For all your design needs . . . call Kristin! You will be in the very best of hands!
