Features & Finishes
All Standard, Never Basic
Your living space should be an escape from the bustle of the city or the noise in your head. To make this a reality, we’ve carefully considered every square foot of our buildings, to create an inviting, personal, and unique home for you.
Start with our standard selections, or upgrade your model with deluxe finishes. Browse our selection of finishes and customize your Solo ADU — View Solo Finishes.
Abundant Natural Light
Large windows let in plenty of natural light throughout our ADUs. A large sliding patio door will greet you at the entrance, bringing in warm light throughout the open floor plan. Around the corner, awning windows provide bright, private light to bedroom and bathroom space.
Interior Finishes
Our interior finishes are customizable and provide plenty of high-end detail without costing you a small fortune. Inspired by a minimalist design aesthetic, we let the container’s shape stand out with clean lines throughout your living space, set against a customizable selection of built-in cabinetry and fixtures.
Built-in Storage
Storage is a premium in smaller spaces, but we make no exception in our ADUs. All models are designed with built-in storage in mind, so you don’t have to worry about where you’ll put the dishes, towels, or bathroom essentials.
Indoor-Outdoor Living
Extending from the front door is our full-wrap outdoor deck with overhang, providing plenty of indoor-outdoor living for sunny days and rainy days. Weather-rated decking reduces any regular maintenance so you can enjoy the outdoors at ease.
Optional Appliance Package
We’ve carefully selected our standard appliances to be energy efficient by Energy Star ratings, yet stylish and affordable. Our combination of appliances are designed to fit in your space and stay out of the way.
Zero Disturbances
Customers often underestimate the cost of daily construction disturbances. Because every ADU is built off-site in our factory, we won’t disturb you or your neighbors with constant construction noise for months or the sudden lack of street parking.
