Plan Overview

A Real Small Home Layout

This 35 by 21 ADU plan is designed to feel like a complete small home, not just extra space. The kitchen, living room, bedroom, bath, closet, and mudroom each have their own defined purpose while still keeping the overall footprint efficient.

The 232 sq ft kitchen opens into a 256 sq ft living area, giving the plan a comfortable daily-use core. A private bedroom, full bath, closet storage, and 66 sq ft mudroom make it a strong fit for guests, multigenerational living, rental use, or a backyard retreat.

Full Kitchen Function

The 232 sq ft kitchen gives this ADU real everyday use, with room for storage, appliances, prep space, and island seating.

Private Bedroom Zone

The bedroom, closet, and bath are grouped together so guests or family members have a more private daily routine.

Mudroom Storage

A dedicated mudroom creates a practical drop zone for shoes, bags, cleaning supplies, and extra storage.
