Ultra-Compact Cottage in ~400 Sq Ft – 1 Bed, 1 Bath

This minimalist one-bedroom cottage offers approximately 400 sq ft of thoughtfully arranged living space—ideal as a backyard ADU, vacation retreat, or tiny full-time home.

Exterior & Curb Appeal

A modest covered porch leads into a simple but welcoming design. Clean lines and compact form deliver charm and practicality on a small scale.

Interior Layout & Flow

An open plan connects the living area and kitchen beneath 10′ ceilings, enhancing volume and natural light. With minimal walls, the main zones feel continuous and uncluttered.

Bedroom & Bath Layout

The bedroom connects via a pocket door to a walk-in closet. A compact laundry closet is placed cleverly between the bedroom and the living space, maximizing utility in the footprint.

Storage & Utility Efficiency

Every cubic foot is maximized—built-in closets, hidden laundry, and integrated living zones all contribute to a feel larger than its size suggests.
