my name is sabrina louie. i am a property owner and lived on the top floor of -- third floor of 12 26 jackson street which is perpendicular to the subject property to the west for many years. the architecture and topography go hand in hand in our neighborhood and work together with a sense of harmony. this proposed project goes against what exists and has existed for many years in knob hill. our third floor rear bedroom and family room windows, from that we enjoy lots of natural light and privacy. and the proposed rooftop penthouse addition with the deck will be built today edge of the building which is already unusually close to my windows. ~ and property. our valued privacy and sense of open space will be less -- will be left and gone forever. to benefit one owner. ~ so, i respectfully ask the board to reject the proposed application for 1521-1531 jones street request for variance. thank you. >> any additional speakers? yes, [speaker not understood]. >>> president fong, members of the commission, mr. sanchez
