Project Overview

20 Kildare Street is a commercial office development encompassing No’s 19-22 Kildare Street and located in a confined city centre site adjacent to Government buildings. Constructed for our long-term, international client, Kennedy Wilson, the development comprises the complete restoration of a terrace of four semi-derelict 18th Century town houses that front on to Kildare Street, and the construction of a new state-of-the-art, seven-level above basement office block with a modern glazed façade to the rear and a new fully glazed three-storey high atrium linking the new building with the sensitively restored historic town houses.

The development allows for a mixed occupancy letting model preferred by our client and encompasses an open entrance foyer with an integrated sesame lift that leads through 20 Kildare Street with reception and concierge desk and through the atrium to the lift lobby and stair core that provides access to the new office block.

The historic buildings provide a total lettable space of 1,642m² spread across the 4 buildings, with a new office block over 7 storeys making up the development.

The basement contains 14 car parking spaces and capacity for 84 bicycles, and houses the main electrical switchrooms, sprinkler pump house and generator rooms. Fully fitted shower facilities are located just off the basement lift lobbies for shared usage by the tenants.
