Setting Standards for over 50 years

National Museum of Ireland, Castlebar

Client: Office of Public Works
Architect: Office of Public Works
Contract value: €10m
Description:
This involved the retention of an existing Victorian Gothic House, which was designed in 1865 by Sir Thomas Deane of Deane & Woodward, and the construction of new Exhibition halls.
 
The existing house and courtyards are situated on a plateau above a series of stepped grass terraces, leading down to a man-made lake.
 
The Exhibition Building, framed by the lake acts as a displaced plinth to the main house.  The storage and conservation buildings are set in line with the existing courtyards, forming one side of a new public space to the rear of the house and also a further private courtyard to the side of the existing courtyards.  The third side of the new public square is defined by a glazed link building that connects the Exhibition and Storage Building and reflects the existing line of the former rear garden of the house.

Key Features:
Restoration works included the removal of all timber flooring to remove dry rot and make sound and replacement.  All timber lentils were replaced and windows reweighted.  The wiring and plumbing systems were upgraded.  Flooring and fireplaces were removed, stored and reinstalled.  Cornices were replicated throughout the house.  All existing doors were fireproofed.  Graining works were carried out to walls to replicate original features.  The walls in the hallway were scraped back and painted to give the impression that they are marble finish.  The Library was upgraded and repainted and all intricate moulding installed.
 
The Exhibition Building has four floors, each relating to a terrace from its entrance at House level to the lowest level at the lake.  The main Exhibition gallery cantilevers out of the terraces, a storey above lake level.  This space contains an island like mezzanine which is overlooked from the entrance level.
 
The Exhibition Building is clad in Wicklow Granite while vernacular materials and details, such as corrugated metal and curved roofs were built to integrate the mass of the storage buildings into the landscape and provide a contracting counter-point to the limestone stone and slate of the existing buildings.
