Can a Jewish institution (or individual) build a construction (such as a school playground) with a view of private property (e.g., a private backyard) if it significantly increases the amount of people viewing/able to view the property, in a way that likely reduces the value of the property and/or infringes on the comfort level of the owner? Possible concerns might include the concept of *hezek re'iyah* - infringement of privacy (lit: damage via seeing). See e.g. Maimonides Laws of Neighbors Chapters [3][1] and 7; Ramban on Bava Basra 59b; Rama on Bava Basra 3a; Taz (Orach Chaim 637:4); Rema (154:7) and Pischei Choshen (Nezikin 14 note 3), cited [here][2]. Similarly, could the institution impose harmful sounds (such as a noisy factory or loud school bell) on its private neighbors? Does it make a difference if the institution received the necessary permits from the local nonJewish zoning board or government? Would it make a difference if the permits were unofficially contingent on "campaign contributions"?
