Lauren and Jeremy
LETTER FOUR is led by our Principals, Lauren Adams and Jeremy Baker. Both grew up working on their family’s homes, creating beautiful, meaningful dwellings with a personal touch. They each desired to apply their expertise to greater challenges, motivating them to move to the city of endless possibilities: Los Angeles.
This dynamic duo finally met in 2008, when a mutual friend connected them for collaboration on a project in Beverly Hills. After cooperating on more luxury builds, the two teamed up to establish LETTER FOUR in 2010. Their goal was to offer a completely turnkey Design-Build service to residents seeking a clear, collaborative, and deeply personalized home-building experience - one that's streamlined by having a single team on board from start to finish.
Lauren and Jeremy structured their firm differently from most in the industry, creating a true 50/50 owner-partnership. Where other firms hire out for architecture or contracting services, LETTER FOUR’s business model relies on in-house collaboration. Operating on these terms holds our team fully accountable for every project, driving us to deliver the highest level of service and craftsmanship to our clients.
We are built for this
All of your needs are covered at LETTER FOUR. We built our firm to address all aspects of custom home building and renovation under one roof, from design conceptualization, all the way to the final walkthrough.
We do this by offering complete licensed Architecture and General Contracting services as one standalone business. You get a single team capable of carrying out your project to the very end. Our experts will guide you through every step, providing the insights needed to produce inspiring designs, masterful construction, and a perfectly streamlined workflow. Through our holistic framework, you’ll enjoy a process that keeps project coordination simple and effective. No worries, no confusion - just clarity and peace of mind.
