1. A method of manufacturing an annular bearing housing for a gas turbine engine, the method comprising:
producing a flange outer structure segment;
producing an intermediate structure segment having an outer radial end, an inner radial end, a body that extends between the outer radial end and the inner radial end, and a branch member that extends outwardly from the body; and
producing a main body segment;
wherein at least one of the flange outer structure segment, the intermediate structure segment, or the main body segment is produced using an additive manufacturing process;
attaching the flange outer structure segment to the outer radial end of the intermediate structure segment; and
attaching the main body segment to the inner radial end of the intermediate structure segment.
