1. Modern 1-Bedroom Cottage with Flex Room

This cozy and cute 18’x37′ plan packs lots of functionality in a small footprint, perfect for a narrow lot or space in the backyard. Just imagine this small modern cottage amongst the lush greenery or covered in snow. This is not a distant fantasy, but a potential reality with the rise of modern ADU plans.
ADU, or accessory dwelling unit, is a term used to describe a smaller, secondary residential structure built on the same property as a primary house. These compact homes are not your typical tiny house with 399 sqft. ADUs are small house plans (usually, under 1,000 sqft) that have become increasingly popular in recent years due to their affordability, versatility, and potential for extra income.
For example, this 649 square foot ADU (Accessory Dwelling Unit) gives you a dedicated bedroom and a flex room. Technically, it can be a 2-bedroom small cottage, as both rooms have closets. Also, the flex space can be your home office, craft room, or occasional guest room, giving this floor plan its flexibility.
Enhance the entrance with a stylish covered porch that offers both protection and charm. Step inside to discover a stunning vaulted space, complete with a cozy kitchen on the left and a spacious living room on the right. And don’t miss the convenient alcove tucked away for all your laundry needs. As you make your way towards the bedroom and bathroom, you’ll appreciate the thoughtful design and layout of this cozy backyard cottage.
