Light wells, skylights and high level windows (withsills of 1500mm or greater) are used only as asecondary light source in habitable rooms2. Where light wells are unavoidable:• use is restricted to kitchens, bathrooms andservice areas• building services are concealed withappropriate detailing and materials to visiblewalls• lightwells are fully open to the sky• access is provided to the lightwell from acommunal area for cleaning and maintenance• acoustic privacy, fire safety and minimumprivacy separation distances (see section 3FVisual Privacy) are achievedFigure 4L.9Light wells can provide for daylight access to common areas.For habitable rooms of apartments, they should only be usedas a secondary light source3. Opportunities for reflected light into apartmentsare optimised through:• reflective exterior surfaces on buildingsopposite south facing windows• positioning windows to face other buildings orsurfaces (on neighbouring sites or within thesite) that will reflect light• integrating light shelves into the design• light coloured internal finishesDRAFT | Apartment Design Guide I September 201499
