No. 15 Henrietta St. consists of the remaining two bays of an originally four bay, four storeys over basement townhouse, with a red brick façade, of the early 1740s. It is located on a cul-de-sac containing the finest early Georgian houses in the city. The street is of unique European significance, being the single remaining intact example of an early-18th century street of houses, which was at the forefront of what was to become the Georgian style.

The building underwent significant restoration which was completed in 2007, and the 18th-century appearance of the interior, including much of the original joinery and plaster work, was restored. Perhaps the most important features of the house are the stucco ceilings on the ground and first floors which were restored in the 1980s.

The building is now the headquarters of Na Píobairí Uilleann, an international organisation involved in promoting the playing, the making, and the teaching of the Irish uilleann pipes. They now plan to reinstate No. 16 Henrietta St. next door.

Tours will include access to the ground floor formal reception rooms, including the rear reception room featuring a mid-18th century figured papier-mâché ceiling, depicting the Four Seasons and including busts of Shakespeare and Milton. Tours will continue up a staircase, belonging to the 1828 division of the house, to the Library and Archive of Na Píobairí Uilleann, the current occupants of the building.
