As you have a cottage next to the crossing the occupant(s) would become the crossing keeper(s) and would become a 'manned' crossing. However, as a 'manned' occupational crossing there would be no requirement to re-hang the gates to open across the tracks as there are examples extant today where this is not the case.
The one here at Church Lane, Reedham doesn't appear to open across the tracks looking at the hinges though they are painted white and have the red warning disc.
You could always apply a pale white wash to the gates to make them more railway-like and at the same time it will turn them a grey colour more associated with weathered and exposed wood.
Personally I don't think an ungated crossing would work as you would have to place a small tree or large bush to act as the focus currently provided by the open far gate seen in the above photo.
Ungated grossings with cattle grids were more common on light and very little used lines, and are older and more widely used then we probably imagine.
I did make up an ungated crossing with cattle grids on a 7mm diorama several years ago and they take up more space scenically than a gated crossing. Ungated crossings on a minor road will also require the additional
TRAINS CROSS HERE road signs.
