After the Acts of Union were passed in Great Britain and Ireland in 1801, all power shifted to London and most politically and socially significant residents were drawn from Georgian Dublin to Regency London. Dublin and Ireland entered a period of economic decline, exacerbated by the return of soldiers and sailors at the end of the Napoleonic Wars.
This marked a turning point for the street, professionals moved in, and Henrietta Street was occupied by lawyers. Between 1800 and 1850 14 Henrietta Street was occupied by Peter Warren, solicitor, and John Moore, Proctor of the Prerogative Court.
From 1850-1860 the house was the headquarters of the newly established Encumbered Estates’ Court which allowed the State to acquire and sell on insolvent estates after the Great Famine.
In the 19th century the rooms of the house took on a different more utilitarian tone. Fine decoration and furniture gave way to desks, quills and paperwork with the activities of commissioners, barristers, lawyers, and clerks who moved into the house.
Family life returned to the street in the early 1860s when the Dublin Militia occupied the house until 1876, when Dublin became a Garrison town, with their barracks at Linenhall.
Dublin’s population swelled by about 36,000 in the years after the Great Famine, and taking advantage of the rising demand for cheap housing for the poor, landlords and their agents began to carve their Georgian townhouses into multiple dwellings for the city’s new residents.
In 1876 Thomas Vance purchased Number 14 and installed 19 tenement flats of one, three and four rooms. Described in an Irish Times advert from 1877:
‘To be let to respectable families in a large house, Northside, recently papered, painted and filled up with every modern sanitary improvement, gas and wc on landings, Vartry Water, drying yard and a range with oven for each tenant; a large coachhouse, or workshop with apartments, to be let at the rere.
