The Sorting Office


At the heart of the Silicon Docks, this former ‘An Post’ site has been transformed into an occupier-centred, state-of-the-art commercial development, very much in keeping with the success of this Dublin 2 city quarter.

Targeting LEED Platinum, the Sorting Office comprises 202,000 sq ft of commercial space over a 7-storey high grade building.

With high-profile tech neighbours and energising surroundings like the Bord Gais Energy Theatre, Hanover Quay and the Convention Centre, the building was designed with collaboration in mind with wide, open floors, a spacious atrium and dramatic features like high-speed scenic elevators.

Details & Amenities

The Sorting Office comprise a seven-storey mixed-use building, with 202,000 sq ft of office space and 6,000 sq ft of prime retail floor space, including space for a cafe.

The seven-storey LEED platinum office block – providing total user flexibility based on open floor plates and economic structural grid – is presented in a strong geometric form, defined by lightness and clarity.

The coherence of the design is emphasised in the choice of facade materials: acid-etched precast, unitized glazing and perforated aluminium brise-soleil fins. The double-height entrance and retail units enhance the streetscape.

Inside, the open, light-filled central atrium is welcoming, airy and peaceful, best appreciated from the dramatic scenic lifts, bringing users to highly flexible staff spaces for work, socialising and collaboration. South-facing landscaped terraces and roof planting soften the aerial perspective and provide outdoor spaces to users.
