Limit the extent of frontage along which a high fence is required.
Where high fencing is included limit its use to the sections of the frontage that specifically require privacy screening, for the remainder of the street frontage ensure that there is a visual connection between the house and the street.
Provide additional screening away from rather than at the street edge.
For example this could be provided at the edge of the patio or terrace that is located back from the front boundary. This will allow the occupants somewhere private to sit, but still allow a connection and views from the house to the street.
Where there is a level change between the street and the private open space, use this to provide privacy for the residents without using high fencing.
