Kustom ADU Client Journey
Discovery & Consultaton
Every great space begins with a story—your story. We take the time to listen deeply, to understand not just what you want to build, but how you want to live. Through meaningful collaboration and intentional design, we translate your vision into a refined, highly personal space that balances beauty, function, and emotional resonance. This is where craftsmanship meets lifestyle, and where your next chapter unfolds in timeless architecture.
Concept & Design
Our design team brings your vision to life with mood boards, sketches, and smart spatial planning. Every detail—from natural light to circulation—is tailored with intention and beauty. We fine-tune your floor plan and prepare for permitting. This is where elegance meets efficiency—balancing your aesthetic with what works best on your lot.
Engineering & Permitting
Engineering & Permitting
With every permit, plan, and detail dialed in, we get your project build-ready. Our team of experienced architectural designers, engineers, and interior designers focus on creating plan sets to simplify the city approval process. Our goal is to minimize surprises and maximize peace of mind for our clients.
Construction & Build
Engineering & Permitting
Our experienced builders and project managers approach each project with exceptional care, guiding it from groundbreaking to completion with precision and integrity. We maintain a transparent process, keeping you informed every step of the way—on timeline, budget, and progress—so there are no surprises, only confidence. Every detail is thoughtfully overseen to ensure your ADU is not only built to the highest standard, but lives as beautifully as it looks.
Interior Design & Finishes
After finalizing the layout and square footage, our interior design team collaborates with you to develop a personalized design board. During this phase, we guide you through selecting finishes—like tile, cabinetry, lighting, and more—to define the aesthetic and atmosphere of your ADU.
Live
We don’t just design structures—we design a way of living. Every ADU we create is a curated experience, tailored to reflect how our clients move, feel, and thrive within their space and property. True luxury lies in the details that elevate everyday moments, and it’s the act of living well within a space that gives it lasting value.
