The Historic Building at Salesforce Dublin was originally a hotel built by the London and North-Western Railway Company in 1883 to service its Irish terminus at the bustling North Lotts International Port. While the building once featured exceptionally decorative brick detailing on the exterior with ornate plaster ceilings and mosaic tiled flooring throughout its interior, it was all in extremely poor condition as the building sat unoccupied for several decades. The goal was to sensitively renovate the building back to life for public-facing events and meetings as well as a mix of quiet work areas and social lounges for employees. The existing building also needed to be universally accessible within and flow directly into adjacent buildings of the wider Salesforce Dublin campus.

The four-story building consists of 2 distinct halves – the west and the east wing. On the upper levels, the east wing sits half-story higher than the west and were only accessible via the monumental stone stair. To make all floors wheelchair-accessible, an elevator was carefully shoe-horned into the west wing and 2 bridges added to connect it to the east wing. These modern interventions are clearly visible within the interior courtyard - the Winter Garden. This flexible central space is used day-to-day by employees to meet or socialize while surrounded by plants and daylight from the glass roof above. For special events, the raised platform at the north end becomes a stage and turns the Garden into an auditorium equipped with event lighting and audio system, acoustical baffles, and hookups for video and additional power. The monumental stair which starts at the Main Lobby, was carefully restored including its original iron and wood guardrail, mosaic tile landings, and a pitched skylight. Throughout the ground level public spaces, the decorative plaster ceilings and wood moldings were reconstructed. Gentle, sloping walks were also incorporated to allow for universal access between the building and the Plaza that connects to all other office buildings on campus. The former hotel rooms on the upper levels were in varying state of decay so some badly damaged walls were carefully removed. This allowed for the rooms to be thoughtfully sized and repurposed as a mix of meeting rooms, work areas, and social lounges for employees.
