A wind turbine tower assembly includes a tubular section having a first longitudinal axis and a base section assembly including a plurality of legs. The base section assembly is configured to be assembled into a base section having the legs coupled together at an interface such that the base section has a second longitudinal axis and such that the legs are obliquely oriented relative to the second longitudinal axis at the interface, wherein the base section is configured to support the tubular section on the legs and in substantially coaxial alignment with the base section.
