WHO WE ARE
We are creators.
At SJ Design Build, we are obsessed with crafting spaces that are elegant, functional, and effortlessly connected to their surroundings. Our passion lies in transforming houses into inviting, well-designed homes that honor craftsmanship while embracing contemporary living.
Founder and contractor Stephen Jenkins has led SJ Design Build for over 15 years. His journey began with co-creating and co-owning a successful Philadelphia restaurant, as well as renovating his own properties – these experiences ignited his passion for design, construction, and creating inspiring environments. Stephen specializes in revitalizing outdated homes while preserving their character, blending the best of the past with thoughtful modern innovations and timeless design.
Collaboration is at the heart of everything we do. We work closely with clients, artisans, and skilled tradespeople to bring visionary concepts to life – whether it’s a small refresh or a full-scale transformation.
Let’s create something remarkable together.
