The lands of Logan House are mentioned as early as 1410, with a tower specifically reported in 1542. It is now clear that there used to be two towers at Logan House.

One dated to the early 15th century (at NT 2038 6300) and was built of sandstone faced with polished ashlar. It had walls some 2.4m thick, and enclosed a space measuring 5.5m by 4.0m. All that now remains of it is a fragment of mortared walling 3.7m long by 0.9m wide, standing to a height of 0.2m high, with the rest of it having been destroyed when an access road was built in 1878.

The second tower has variously been dated from around 1230 right up to the 16th century, and had similar dimensions, measuring 6.0m by 3.2m within thinner walls of 1.2m thick. It still stood to a height of 6.0m in 1915, but nothing now remains.
