Many tiny houses use the loft as a sleeping area. This tiny house has a front and rear loft, both of which provide substantial added storage for those things that need to be kept on hand but are not necessarily used all of the time.
The nook serves as a daybed/sofa/sleeping area with 3 storage cubbies beneath, and a trundle bed beneath that.
Wide window sills provide added space for plants and knick knacks. Overhead can be found pegs and storage bins, and in the kitchen area pegboard provides versatile storage without consuming space with cabinetry. Cloth bins conceal much, thus avoiding what could be the look of clutter. Bookshelves help with spatial definition, as do softly transitioning paint colors.
Some wire shelving provides more storage space without adding bulk and weight.
