What is a Granny Flat?

A granny flat is a self-contained living unit built on the same property as a main residence, often used to house family members, such as elderly parents. While commonly referred to as accessory dwelling units (ADUs), granny flats are often tailored for multigenerational living, featuring accessible designs and ample storage. These units offer a blend of privacy and independence while maintaining close proximity to the primary home, making them ideal for family housing or as a potential rental space.

Efficient 3 Bedroom, 1 Bath Layout

This 3 bedroom granny flat plan is designed for maximum space efficiency and comfort. Two bedrooms are located together on one end, while the third bedroom is placed on the opposite side of the unit.

Key Layout Features:

• Three Bedrooms in a Narrow Space: Fit three bedrooms comfortably into a compact, under-900 sq ft layout without compromising functionality.
• Open-Concept Great Room: The kitchen and living room are combined into a central great room, perfect for entertaining or family gatherings.
• In-Unit Laundry: A dedicated laundry area with a washer and dryer adds convenience and helps keep the space organized.
• Narrow Footprint for Small Yards: At just 17 feet wide, this layout is perfect for narrow properties or tight backyard spaces. To meet the 4′ required ADU setback from the property line and typical 6′ setback from the main home, you just need 27′ feet of space for this plan.
