About This Layout

Cincinnati studio apartments with improvised sleeping lofts built over kitchen areas combine two of the most problematic features of compact urban living. Cooking heat and humidity rise directly into the sleeping platform. The loft typically has minimal headroom. And the kitchen below is visually exposed to anyone on the sleeping level, eliminating any sense of separation between cooking and sleeping zones.
