Having idea about the standard size of rooms as well as its location in typical residential building is very important detail for planning and construction of the project. The room sizes and their location allow planning enough space for movement, enough dose of sunlight and natural air for the residents of the home.
Living room should be larger than other rooms because there the family sits most of the day, the guests are comming there and sometimes it is used for greater family gatherings. So, the standard size of the living room may range from: 4200mm (14ft) X 4800 mm (16ft) to 5400mm (18ft) X 7200mm (24ft).
Bedrooms should be located in the part of the house where can be provided enough privacy and ventilation. It is good if these rooms have natural light in the morning and it is good to have closet and bathroom attached. Standard size of bedrooms may range from: 3000mm (10ft) X 3600mm (12ft) to 4200mm (14ft) X 4800mm (16ft). Guest room is a room that should be close to the living room and to have good light and ventilation. Standard size of guest rooms may be: 3000mm (10ft) X 3600mm (12ft).
 

Dining room is supposed to be near the living room and the kitchen. Often it is all in one open space of the floor. Size of the dining room may range from: 3600mm (12ft) X 4200mm (14ft) to 4200mm(14ft) X4800mm (16ft).
