The one and only specific situation for a mother and child situation is pregnancy and its inherent love.
The idea is to construct the building as a double heart, symbolizing the most intimate relationship between mother and child in pregnancy. The bigger building contains gynecology while the smaller building contains maternity.
Depending on space available there a two proposals:
1: Laying Buildings (foil 1)
smaller heart inside bigger heart
The two hearts connect at the point of inflection. From building point of view this is the traffic hub.
Child heart or the whole heart may be covered by a glass roof, but the basic shape must be absolutely visible day and night
This layout becomes even more dramatic if built on a soft slope.
2: Standing Buildings (foil 2)
smaller heart being offset lateral and sagittal eventually slightly turned too
Set a relaxation area with tropical plants in the inner outside of the outer heart
*****
Give it a dramatic night illumation (similar to foil 3)
