14 Henrietta Street | Georgian townhouse to tenement dwelling

Dublin City Council began a process to acquire the house in 2000 as a direct result of the Dublin City Heritage Plan 2002 – 2006 and the Henrietta Street conservation plan. The purchase of the house was completed in 2008 and following this they embarked on a 10-year long journey to rescue, stabilise and conserve the house, preserving it for generations to come. In 2018 14 Henrietta Street opened its doors to the public.

The restoration and conservation of the building was led and funded by Dublin City Council, with additional support from a Centenaries Capital Grant from the Department of Culture, Heritage and the Gaeltacht.

Conservation and restoration

Significant work was required to save the front façade, the roof and rafters, the brick on the rear elevation and sash windows, of which only six of 18th century origin remained.

Internally the condition of the house was poor, with major structural failure, poorly executed previous repairs and moisture ingress causing decay and localized growth of Dry Rot.

The back staircase was unsafe to use and the basement flight had lost all structural integrity, preventing access beyond ground floor level. Treads had worn away and all but 7 balusters had been entirely removed from the stairs. Floor joist ends were rotted in many places but particularly at ground floor level. The floor structure of the closet space (the small room at the end of the sequence of rooms) had been removed throughout which further affected the house’s structural stability.

Internal wall surfaces, predominantly of late 18th century, were largely intact, particularly in the back hall and stairs where Reckitt’s Blue and Raddle red, synonymous Dublin tenement paint colours, survived in the entrance hall, back hall and stairs.

Technically, the project was loaded with challenges, not least the rebuilding of the bottom section of the rear wall which was supporting the upper section of the house, the restrictive size of the site and its urban location which made access difficult.

Use of traditional crafts and skills

The 14 Henrietta Street conservation project employed expert craftspeople in the area of specialist stone repairs; wrought iron repairs; wallpaper conservation and reproduction; linoleum reproduction; specialist joinery repairs and new joinery; specialist historic paint and surface finishes; specialist decorative plasterwork (cleaning; repairs; restoration); lime plaster and render (including renewal and repair); and repairs to mid-to-late 20th century tiled fireplaces.

In addition to the traditional skills, expert craft skills are apparent in the bespoke concrete flooring; the solid wall brickwork of the new return and, the casting of new fireplace surrounds. It is a notable aspect of the works that practically all repairs and works have been done in-situ (the steel for the new stairs and the timber glazed extension are the only off-site constructed elements).

The conservation of 14 Henrietta Street has been recognised with a number of awards.
