Plan Overview

A Compact Backyard Office With A Full Bath And Flexible Work Space

This 20 by 15 casita home office floor plan uses 300 sq ft to create a focused backyard workspace with a 238 sq ft open office, full bath, and dedicated storage closet.

French doors, multiple windows, and a simple open layout make the plan feel bright and flexible for remote work, consulting, a creative studio, or a quiet guest-ready office space.

Focused Office Space

The 238 sq ft open office gives the plan enough room for a full desk setup, client seating, storage furniture, and flexible studio use.

Full Bath Included

A 54 sq ft bath makes the backyard office comfortable for long workdays, guests, or future flexible use beyond a simple work room.

Compact Storage Closet

The 8 sq ft closet keeps supplies and equipment organized while preserving the main office as open, uncluttered workspace.
