About this asset

This basement window well Revit family features a moulded white body, an integrated bottom drainage outlet, and a protective mesh safety cover. The assembly presents a prefabricated basement lightwell unit with smooth curved interior transitions and an open rectangular back designed to abut subterranean foundation walls. A bright white finish lines the composite basin to maximise daylight reflection downward into below-grade rooms. Along the upper perimeter, a profiled rim seats a sturdy metal mesh grate with a diamond-pattern expanded steel screen. A recessed circular drain opening is formed centrally along the sloped floor to accommodate drainage connections and prevent water pooling against foundation openings.

The download is a 379 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

In Revit, insert this RFA component along exterior subterranean walls adjacent to basement windows or walkout areas. The family aligns with floor slabs or topography levels, allowing clean integration within foundation wall sections and exterior building elevations. Visibility graphic settings can be adjusted in section and 3D views to coordinate daylighting pockets with surrounding grading cutouts and external site boundaries.

Engineered for single-family residences, townhouses, and mixed-use buildings with inhabited below-grade rooms, this element provides vital light admission, ventilation, and emergency escape access. Specifiers commonly integrate this basement lightwell alongside subterranean casement windows, concrete foundation retainers, and perimeter perimeter drainage beds. It serves as an essential component across technical construction documentation and detailed exterior wall sections.
