Project Overview

Faithful restoration of the Palm House Complex within the National Botanic Gardens of Ireland. The project included the removal of glass, dismantling and transportation to the contractor’s yard of all ironwork and timber, together with initial blast cleaning of ironwork to allow inspection. All elements were restored, returned to site and reassembled.

The existing complex had been closed to the public due to the danger of falling glass; such was its state of disrepair. A detailed three dimensional survey of all of the existing components was undertaken and the structure disassembled. Each item was removed off-site for a detailed inspection or replacement. Some of the wrought iron members had to be replaced in the UK together with some of the timber in Asia.

The two side wings of the house, namely the Orchid and Camellia Houses, were simultaneously restored. The rear stone building was retained and restored with new visitor access for the disabled, and renewed service access to the internal Palm House gantry walkway.
