What is the feng shui of three self-built houses in rural areas? The middle bay is small and the bays on both sides are large.

Not very good.

The three rooms are either made to be the same size, or they are larger in the middle and smaller on both sides.

The three rooms are equally wide. The middle room is called Tangqian in rural areas and Zhongmingtang in Feng Shui terminology.

The small bright halls in the houses on both sides are large, or the main doors are opened too wide, which will cause the evil spirit to disperse. If you don’t gather energy at home, your bright hall will be small.
