This depends on the height, design and position of the screen, as well as local requirements. A tall, solid screen may be treated differently from an open balustrade, while adding a screen to a balcony may change a building’s appearance. Check with the relevant local authority and, where applicable, the property owner before ordering.
A low, transparent screen may be assessed differently from a tall, solid one, and its position near a property boundary or a road can also matter. On balconies in blocks of flats, taller panels or replacing clear glass with frosted glass may affect the building's appearance. If your property is subject to leasehold or building-management restrictions, check what changes are permitted. A tall screen is also exposed to greater wind forces and must be designed accordingly.
