Kilcrea Friary consists a series of buildings located around a main church or chapel.
Although in ruins, the abbey is still relatively complete, including its tower, cloister and the surrounding east, west and north facing buildings.
The abbey's chapel contains a nave, chancel, transept and an L-shaped aisle.
It is entered through a doorway in its west gable.
An arcade separates the nave from the south aisle and transept.
The chancel contains a large window on its east wall, which has lost its original intersecting tracery.
The other four pointed windows are fixed on the south wall via segmental-headed embrasures, and contained either single or twined glass panes (lights).
No trace survives of the high altar which was likely positioned under the east window, but an arched piscina is found nearby in the south wall.
Adjoining the chancel is the sacristy which was added in the 16th century, above which is the scriptorium.

The cloister area is located north of the church.
The arcades are missing from the cloister, although the roofless two-story ranges are well preserved and mostly intact.
The remains of the chapter room and refectory or possibly the kitchen (33 x 21 ft) are located on the east range, above which are the dormitories.
Their is evidence in some records that the friary once contained an infirmary, however the precise room has not been identified.

The scriptorium measures 39 x 17 ft and probably also functioned as a study-room.
As with all such rooms in medieval Irish friaries, it was the most well lite room on the site; the room in Kilcrea contains 11 tall two-light windows.

A recess for a holy water stoup is located outside the doorway, and in the gable over the doorway are the remains of a large, three-light window.

The tower contained four storeys with timber floors supported on stone corbels.
Each storey was lit by plain, narrow, flat-headed windows.
Except for the top storey where there is a single ogee-headed light in each wall.
It is broader at its base in order to accommodate the stairways and passage to the tower.

A 15th-century manuscript written at Kilcrea is preserved in Rennes, France.
