Do you know what builder/house that was in?
I’d be interested to see it in some more detail.
doogs82 the deisgn above in the photos is typical of sharknose handles.
The dark shadowline you see is a polyurethane construction rail behind the drawer fronts. This is normally around 50mm in height and is fixed in position. This limits the amount of available drawer space.
On a three bank drawer with this type of setup you loose a total of 150mm in drawer space height.
