I was wondering about the correct procedure for making a new bracha and changing places. If for example, I make a bracha in the upstairs of my house and then move downstairs (or move to a new room) would I require a new bracha? If I can still see my original location, for example, if I am in a long room and move from one end to the other (and thus can still see the original location) would a new bracha not be required? Thank you.

Shalom, Thank you for your question. The laws of changing location as it effects blessings on food are complex indeed. You will need to spend some time learning the subject in depth (there are some wonderful books in English, including "The Halachos of Brochos" by Rabbi Bodner). Here are short answers for your particular questions – changing locations from room to room inside one house is a matter of debate amongst the early Rabbis. Because of this, one is well advised to have intent before saying a blessing that one intends to eat the food in all the rooms of the house. If such intent was in mind at the time of the blessing, one can move from room to room freely, and no new blessing is needed. If one did not have such intent in mind, we none the less follow the opinion that no new blessing is needed. (See Biur Halacha 178,1 "BeBeit Echad"). Moving from one side of a room to another, even in a very large hall, does not require a new blessing to be said. (See Shulchan Aruch 178,1). This is true even if you cannot see your first location. The ability to see your first location outside of one building is also a matter of debate. Because of this debate we try to avoid such situations. However, if one did in fact, for example, leave the house to their yard from where one can still see the room they said the first bracha in, they should not say a new blessing. (The exemption is where there is a walkway or street between the two locations, when even if one can see the first location a new blessing is needed). I hope this will be of some help to you.
