Even if there is an undeveloped plot there, I don't believe it is easy to enforce windows there. But you can place windows facing south or west (the direction is not clear from the north arrow and site plan), and the children's rooms should then be arranged in a row with a view of the greenery and not onto a garage courtyard. Instead, the living room, which, due to the separation from the kitchen and dining area, is more associated with the evening, can do without a panoramic view of the greenery. Otherwise, I would have also accommodated the office and guest WC on the first floor, with the bedroom separated from the children's rooms. A skylight would somewhat relieve an interior parent’s bathroom :)
