Smartly Designed 1,200 Sq Ft ADU for Flexible Living

Copper Nest is a carefully planned 1,200 sq ft ADU that combines efficiency with comfort. Featuring four bedrooms and two full bathrooms, this design offers an optimal balance between private and shared spaces within the maximum square footage allowed for accessory dwelling units in California. Unlike smaller ADUs, Copper Nest provides the flexibility to accommodate larger families or multiple tenants while still maintaining a compact and cost-effective footprint.

Floor Plan Overview

• Total Living Space: 1,200 sq ft
• Dimensions: 43′ x 28′ (rectangular footprint)

The central hub of this ADU is its open-concept living area, which integrates the kitchen, dining, and family space into one seamless environment.

Oversized windows and thoughtful orientation allow natural light to penetrate deeply into the interior, improving energy efficiency and creating a bright, inviting atmosphere throughout the day.
