Thanks for your advice, Mr Cecil. Between the two best positions recommended, we feel that B is the better of the two. However, position B is right in between 2 doorways (if including the service balcony beyond the kitchen, that makes 3). The path is very windy all the time, no matter how small the main door opening is. We are totally clueless as to how to keep flames (candles/"you deng") lighted in this path. Challenge 1: How can we remedy this? Is there a design for altar that 'blocks' the wind or should we get something to shield the candles or "you deng" and the spiral incense? Challenge 2: Due to the space constraints, may we place chairs against the same wall. Must we keep the wall clear of things? We were thinking of building a rackfor shoes and going-out stuff, behind the door on the same wall. Challenge 3: If we want to invite the 'Sky' and 'Earth' gods in too, will we be able to use the same position for 'Earth god'? Thanks!
