A house plan with a loft typically includes a living space on the upper level that overlooks the space below and can be used as an additional bedroom, office, or den. Lofts vary in size and may have sloped ceilings that conform with the roof above. Lofts in home plans can include features such as skylights or windows that let in natural light and provide a feeling of open spaciousness. Lofts may also have unique architectural elements such as exposed beams or vaulted ceilings.
