Our Step-by-Step Design Process

1. Discovery

Every project begins with a conversation. We learn about your home, your routines, and how you want your spaces to feel. Whether you’re redesigning a single room or a full Bay Area residence, this is where the creative process begins.

2. Onboarding

From your preferred colors to your travel destinations, we inquire about every detail of your personal taste to establish an intimate understanding of your lifestyle. This personalized approach ensures that every project reflects the heart of your California interior design story.

3. Conceptual Design

We create detailed moodboards, space plans, and schematic drawings that capture the overall direction of your project. You’ll see your ideas translated into a cohesive visual plan that defines your unique aesthetic.

4. Design Development

Here’s where your vision becomes tangible. We curate furnishings, materials, and finishes, finalize drawings, and coordinate with trade professionals. This stage transforms concepts into detailed designs ready for execution.

5. Procurement & Project Management

Fondly known as the execution phase, this is where our Marin County interior design team takes care of everything: ordering, tracking, and managing every detail. We oversee vendors, deliveries, and construction timelines to ensure your project runs smoothly from start to finish.

6. Installation

Where the magic happens! We work closely with our professional delivery teams and installers to carefully place all furnishings and accessories to create a beautifully curated and cohesive space you’ll love.

At Arntz Interiors, our approach is designed to make complex decisions feel clear and manageable — so you can actually enjoy watching your home take shape.
