Torrekua House has a noticeably square ground plan and hip roof. It stands at one end of the town on the corner of a block, from where it protected one of the entrance gates.
Its main facade is made in sandstone ashlar, and the other two in masonry. One of these, that forming part of the wall enclosing the town, is plastered and all of its openings were made after its construction. The main facade also features a couple of uninteresting openings of later manufacture. Outstanding among the original openings is a pointed arch entrance with IHS (Iesus Homine Salvator) on its keystone. On the first floor there is another similar entranceway, narrower and currently blocked, reached by a stone stairway clearly marked on the wall. On the first floor, blocked up, are two geminated, trilobate windows with no mullions. The finishing touch is simple wooden eaves. On the left extreme a length of wall sticks out perpendicularly at what was probably the location of the town gate, on the front of which is a modillion with a roughly carved face.
