There is a gap between the houses opposite the office.

This question is too general. Is the office a building or a bungalow? This is a building. What floor is that? Is the house opposite a building or a bungalow? Its height? What is the distance between the two buildings? Is there a road or alley or green space or fence in the middle?

The spacing is too large, exceeding the building height, which is ignored; If the spacing is too small, it is less than one meter, and the windows are sealed from window to window, which has nothing to do with the wall; The green belt and fence in the middle can also be ignored;
