I was unable to read the plaque on the wall but I have been told that it commemorates Nathaniel Clements the first resident of the house.

According to my tour guide [I took a tour before moving to Henrietta Place about twenty years ago] Brendan Behan once said it was typical that Dublin’s most fashionable street is named after a “Right Royal Bastard!”.
The street is actually named after Henrietta FitzRoy, Duchess of Grafton, daughter of the Earl of Worcester who was married to Charles Fitzroy. The unfortunate Henrietta was married at 22 but died about thirteen years later having given birth to ten children.
In the 1950s there were at least seventy people living in this house.
Since about 1968 it provide studio space for twelve artists but I do not know if it is currently occupied.
This year it was on sale for €1,200,000 and then the asking price dropped to €850,000. Back in 2011 the asking price was €1,850,000 with an indication that as it was in such a decrepit state that even after spending €1.85 million to buy it the buyer would need at least another €3 million restore it. [Update: a reader contacted me to mention that it originally came on the market with an asking price of €3.25 million]
The official description reads as follows: "This house was built for Nathaniel Clements, who developed much of the street, this house being a mirror of No. 3. The interior retains an original double-height open-well staircase and early dog-leg closed-string service stair with original plasterwork and joinery throughout. Despite the external appearance, the interior contains some important elements and forms an important part of this early Georgian streetscape."
