Plan Overview

Compact, Bright, And Easy To Live In

This 25 by 16 casita floor plan keeps the daily-use spaces open and efficient. The 226 sq ft living area connects the lounge, dining spot, kitchen wall, and sliding door so the compact footprint still feels bright and easy to use.

A private 104 sq ft bedroom and 60 sq ft full bath sit together on the right side of the layout, giving the plan a clear guest-suite feel while preserving a simple path from entry to kitchen, living, bedroom, and bath.

Open Living And Kitchen

The main room combines the kitchen wall, dining table, lounge seating, and TV wall in one simple everyday space.

Sliding Door Connection

A wide sliding door brings daylight into the living area and creates an easy connection to the patio or yard.

Private Bedroom And Full Bath

The bedroom and bath sit beside each other for a comfortable one-bedroom guest suite inside a compact 400 sq ft plan.
