A full-service design and construction firm creating beautiful, livable spaces across the Bay Area.
Our construction team isn’t an afterthought — it’s an extension of our design process. When we say we build what we design, we mean it. With one integrated team, one shared vision, and transparent communication from start to finish, you stay confident while we turn your ideas into reality.
As seen in:
One vision, one process, no hand-offs.
Clear communication, no surprises.
Every detail built to design intent.
Our design-build team brings creativity and craftsmanship to every project — from luxury homes to distinctive commercial spaces. With one integrated team, one shared vision, and transparent communication from start to finish, you stay confident while we bring your ideas to life.
Every home tells a story. We listen closely to understand how you live, what inspires you, and what comforts you most—then translate that vision into timeless, functional spaces.
Our in-house construction team ensures your design intent is preserved with precision. From daily on-site supervision to rigorous quality checks, every stage is managed with care, accountability, and attention to detail.
No hidden costs. No surprise change orders. Just clear budgets, open communication, and a collaborative experience that keeps you informed and confident from start to finish.
Construction is where ideas become physical—and where details matter most. Our role is to protect the design intent while managing the realities of the build with precision and care.
We oversee every phase of construction, coordinating trades, timelines, and materials to ensure the work is executed exactly as planned. Clear communication, thoughtful sequencing, and hands-on involvement allow us to maintain quality without disruption.
By approaching construction as an extension of the design process—not a separate handoff—we create spaces that feel cohesive, intentional, and well-built. The result is a finished home that reflects the vision from the very first drawing through the final walkthrough.
Each project is a reflection of the people who call it home—designed with intention, built with integrity, and finished with care. From modern remodels to new builds, our portfolio highlights the craftsmanship and creativity that define every JDS Design Build project.

The feature celebrates JDS’s integrated approach to design and construction, its dedication to transparency, and the client-first experience that defines every project.
Andrea’s vision — to create spaces that feel as good as they look — continues to reshape how homeowners experience the design-build process.
From bespoke cabinetry and tailored lighting to seamless millwork and precise alignment, our team’s obsession with detail transforms good design into extraordinary craftsmanship.
We collaborate closely with artisans and trades who share our commitment to excellence, ensuring every finish, fixture, and frame meets the JDS standard — refined, timeless, and distinctly yours.
I Absolutely Love My New Window Coverings! Working with Jeffrey Design Studio was such a wonderful experience! From the very first... Read More meeting, they really took the time to understand my style and what I was hoping to achieve. Andrea and Jen helped me choose fabrics and designs that fit perfectly with my home, and the end result is just beautiful. The whole process was smooth and enjoyable — no stress at all.

Shauna P.JDS Design Build, did a fantastic job designing our master bathroom addition, existing bathroom, and master bedroom remodel! I’ve never... Read More worked with a professional designer team before, but I’m glad we did. Andrea and team knows the critical points of construction - and it passed city permit. The team has a plan, in phases from exploration, to concept, and design, then implement in partnership with a contractor we selected through them. Honestly, I had no idea how my husband and I would ever manage to agree on style, but their process brilliantly supported both our interests. The whole project was laid out from start to finish- it came out gorgeous! Everyday I cant wait to go home and enjoy. Also a big thank you for the gift of gorgeous ferns! Thank you JDS Design Build Team! Photos are various stages but give an idea, shower was completed with a gorgeous partial glass enclosure, we love it!

I will always refer you over any other to my friends and family!
Mark J.5-Star doesn't do this team justice. I worked with Jeffery Design on a complete home re-design. After 15 years in... Read More our home, we needed to fall back in love with our design and functionality or consider selling. I am so grateful we found Andrea and her team and they guided us through the process of making our home our dream home. First and foremost, this team designs for you! They are more concerned with how you will live and enjoy your space and not their personal design preferences or goals. They pushed me to consider new design ideas and also respected my "must haves" or "hard no's". In every project there will be surprises and challenges. The sign of a great partner is how they show-up and stick with you to find the best solution to those challenges. Andrea and her team were there for every bump in the road, clearly communicating through the process and working closely with their partners and vendors to bring us the best result. It's hard to pick our favorite "space" or feature. The invisible induction cooktop that provides more prep space in our kitchen. Custom wine storage built under our stairs, maximizing space and design. My home office that feels like a retreat and destination where I spend 10+ hours per day. The list goes on. Our family can't thank Andrea and her team enough for creating a beautiful space that feels 100% like "us" and works so much better for our family.
Jennifer T.We hired the Jeffrey Design Team to design a complete remodel of our mid-century home to include bathrooms, kitchen, all... Read More electric/lighting, custom windows and doors and a bedroom addition with a beautiful walk through closet. They handled everything from the architectural plans, city permits, working with specialized contractors and listening to our wants and needs. It was the one-shop stop we needed. The design they presented was beyond our expectations and we love the finished product. Our home feels like home!
Marla V.Your home — or workspace — deserves a team that listens, collaborates, and delivers. From first sketch to final walkthrough, JDS Design Build turns ideas into spaces that inspire and endure.
