Throughout Hillforest there are walk-through windows that allow easy access to all porches and balconies. These windows replaced the need for doors at these locations and allowed the windows to be larger and more functional. An extra row of panes was added to the lower sash and when raised, the window slides into the wall above, creating an entrance/exit approximately 5 feet in height.  The walk-through windows in the Morning Room give access to a semi-circular balcony and afforded the women a fabulous view and ventilation.
