B5.6.3 Designing balconies and terraces

All newly proposed balconies or roof terraces should include effective drainage systems to manage rainwater safely and discreetly. Acceptable solutions include concealed gutters, integrated downpipes, or drainage spouts that direct water into a continuous drainage system, ideally a downpipe integrated within the building facade or structural elements. The chosen system should be robust, low-maintenance, and visually integrated into the overall architecture of the building.

In Highly Urban Area Type (80+ dph) or Urban Area Type (50+ dph), fully controlled (non-drip) drainage systems should be provided to prevent water from spilling onto lower balconies or public areas below. Open or uncontrolled edge drainage should not be used.

All newly proposed balconies and roof terraces should:

• be accessible from the main living space to maximise use and accessibility for all occupants and protect the privacy of bedrooms

• provide level and accessible thresholds to encourage frequent use and enhance the overall user experience

• avoid direct overlooking of neighbouring balconies/terraces and habitable rooms

• include 1.1 metre balustrades with solid or semi-solid panels (rather than open railings or fully transparent glass) to increase privacy and provide wind and weather protection (note that in some instances the height of the proposed balustrades may need to be increased to 1.5 metres to provide further safety measures)

• ensure any integrated seating or planters are securely anchored to prevent furniture being moved or blown from height

• position seating away from perimeter edges to reduce climbing risks and enhance safety

• integrate appropriate lighting that minimises light spill, with controls such as timers or sensors where needed

• provide secure access control to roof terraces or shared balconies to prevent unsupervised access, especially by children
