Hi, I have a few questions about organising the feng shui of the house and the outdoor patio area. 
 
I recently had a roof put over the back of the house. 
 Question 1: How will the feng shui be affected if I enclose the whole area with a security grille like the one in the photo I attached? 
Question 2: 
I was thinking of putting the barbecue kettle and possibly a second stove as illustrated in the diagram attached. Is this a good idea near the back door? If not, where would you recommend to put the barbecue? What are the implications for both choices and are there any things I might do to remedy?
