Located at the junction of East wall and Alexandra Road and adjacent to the Dublin Port Company building, the Red Brick Building, formerly an electricity transformer substation is one of the earliest industrial heritage buildings dating from c. 1922, however it reveals as much underground as above ground which Dunwoody and Dobson recently uncovered.
The single-bay two-storey substation is built in red brick, laid in Flemish bond, and has an arched entrance door to the front with granite front step. The main entrance is flanked by two circular windows bordered by brick surrounds and pivoting timber casement windows. On the North elevation, a half-arched window can be seen.
Dublin Port who are committed to preserving port heritage added the building to the list of protected structures in 2017 under the Dublin Port Masterplan 2040. The Diving Bell and Crane 292 form some of projects already completed, with further plans to integrate the city and the port and provide greater public access to heritage assets within the port to create a cultural hub at the former Odlums Flour Mill.
In the 18th Century, Dublin was, similar to Amsterdam, where land was reclaimed from the sea. Marine barricades and fortifications were built to safeguard Dublin city, and this was known as the sea wall and was thought to be in the location of the red brick building.
Dunwoody and Dobson were awarded the contract and commenced work in September 2021 and are working in close co-operation with the project team on this special restoration project. The scope of work was to stabilise the red brick building, which was on the verge of collapse, locate and expose the sea wall and build a glass structure alongside which will become an orientation space for visitors. Situated on the busy east wall road, it is not often that you can stop to admire such as building with lorries trundling along from the docks.
The building was in a precarious position with a major fissure on the southern elevation which happened to be sitting on the sea wall which held the wall in situ, while the crack transferred across the floor fracturing the raft and leading up the facing wall. The roof gently pulled away from the west parapet but remained weathertight. It is a testament to the building that it is has remained standing at all.
Dunwoody and Dobson uncovered the wall a few months into the project and as they progressed east, they discovered a further wall. It was slow and meticulous work with the archaeologist on hand to oversee the excavation. It is thought that the second wall was the sea batter wall with sand fill of 2 metres and a parapet wall inside that which would have led to the pathways beyond. When the sea wall was cleared, they found that the Dublin kalp stone had been removed from the face. Further excavation to approximately 4.5 metres from finished floor level were completed and they started to get water, they discovered stone on the flat which indicated that when they were reclaiming, they reused the kalp stone facing for other projects in the vicinity. The scope of work in excavation was constantly under review and under the close supervision of the archologists and the design team, with finds such as pieces of pottery, clay pipes and shoe leather.
The refurbished building will be supported by a new internal steel framing support structure, with a glazed section of floor giving a view to the old sea wall structure below.
