The existence of residential houses will distort the ion flow field under high-voltage direct current transmission lines. High efficiency electric field computational method is required during the engineering design. In this paper, the surface charge method is applied in the space-charge-free electric field computation, and a half-analytical integration strategy is presented to accelerate the computational speed. Then, ion flow field around the house is computed based on Deutsch assumption. The calculation methods are validated by the experiment in the laboratory. Electric field intensity around the top edge of steeple rooftop is larger than other areas, and the field distribution characteristics on the steeple rooftop are significantly different from flat rooftop.
