If your children are almost the same age, the difference between them is not greater than 4-6 years, then you can dedicate a room for them and without separate space for each child. You can make separate spaces in the kids room for games, leisure and learning, because probably boys will play together. If the children are small and do not go to school, better is to devote biggest space of the room for games. In the room should not have allot furniture because the space for the games would be smaller and the children could be hurt.The bed must occupy minimal space, because there children will only spend a few hours while sleep. The optimal result will be a bed on two floors or bed with slid. On that way you will save a lot of space.sourcesource
