I have a 3BR/2BA home that has a detached garage. Behind the garage is an efficiency with it's own bathroom and about 240 sq ft. of living space. about 24 feet long by an average of 10 feet wide, actually made up of two separate sections, one is 12x8, the other 12x7. Need to make the unit as cozy and space efficient as possible. Celing height is only 8 foot. Want small kitchenette as part of the package. Maaaaybe a murphy bed makes sense?
