Welcome! We are thrilled you’ve stopped by to learn more about A4 Homes.

We founded A4 Homes in 2019 after a decade of dreaming of creating our own construction company, but our story began years earlier in Steamboat Springs, Colorado. We met through mutual friends and, at the time, Chris was working on a framing crew building the world’s largest log home and Kate was headed off to college. 

Now, seventeen years later, we find ourselves happily married, raising our two beautiful daughters, Amelia and Madison, and enjoying everything the Bay Area has to offer. A4 Homes is a statement of our family (quite literally the “Adams Four”). The four of us are stronger together and offer each other the motivation and ambition to do great things. We love living our dream of being custom home builders by helping families create the home of their dreams.

Because our family is our number-one priority, we pride ourselves in creating spaces where families are able to thrive. We are fortunate to be able to work together building custom homes, and we’d love to work with you too!

Chris & Kate


Chris Adams awarded Leaders in Pro Builder's 2023 Forty Under 40

Recognizing and celebrating our 2023 Forty Under 40 class of energetic, innovative young leaders representing the future of the housing industry

Chris - Owner & Project Manager

Chris carries on the family tradition of being a hard worker and having an honest work ethic. His passion for building stems from listening to stories from his grandfather building his house for his family with his bare hands. He was always told that working in the trades would never be dull or boring and that every day will present a new challenge. 

Chris began his journey in custom home building over 20 years ago in Steamboat Springs, Colorado pushing brooms and cleaning up job sites. With the work ethic instilled in him by his grandfather, he worked his way up through the ranks of the construction industry learning the ins and outs of the building trades. It is because of the nature of his education that he understands the importance of bringing that hands-on building philosophy to each project from start to finish. His dedication, attention to detail, love of construction, and natural talent are apparent in all that he does. Chris strives to provide a product of the highest quality that will last for years to come.

In his free time, Chris enjoys mountain biking, riding dirt bikes, and spending quality time with his wife, Kate, and their two daughters Amelia and Madison.

“Chris truly has a passion for building custom homes. He started in the construction industry over 20 years ago pushing a broom and worked his way up the ranks from there. He was encouraged to obtain his contractor’s license by multiple architects four years ago and is now building luxury custom homes in the communities of Atherton, Menlo Park, Palo Alto, and Portola Valley in California. His down-to-earth demeanor brings an element to the build process that is one of a kind.” —Kate Adams, co-owner and office manager, A4 Homes



Kate - Owner & Office Manager

Kate is responsible for the day-to-day operations of the A4 Homes office: monitoring and tracking job costs, managing accounts receivables and payables, process development, and making sure the team has everything they need to work effectively and efficiently. She works closely with our vendors and trade partners to ensure that the financial investment in our clients’ new home is a positive and stress-free experience. 

Kate is adept at prioritizing, multitasking, and organizing company goals and initiatives. Prior to founding A4 Homes with Chris, she was an underwriter in the surplus lines sector of the insurance industry for ten years. Her background in risk management and attention to detail prove to be a key asset to the business. Kate graduated from the University of Denver in Denver, Colorado with a BS in Business Administration. 

In her spare time, Kate can be found enjoying the outdoors, gardening, horseback riding, or baking something in the kitchen with Amelia and Madison.
