100 Stephen’s Green

With SONICA at the helm, the project ran seamlessly on-site – any unforeseen events were dealt with quickly and programme was never compromised. We were very impressed with the quality of their finishes and found the whole Company to be very well organised and efficient. We would be very happy to work with them again.

the work

the story

100 St. Stephen’s Green, a red brick Georgian located in the iconic South West corner of the Green, was originally sub-divided into six dated apartments. Sonica were engaged by property owners DAVY to develop the building into a prestigious single tenancy office above a 1 bedroom apartment in the basement.

The nature of the premises, and it’s status as a listed building, meant the project had to be handled with the utmost care. Working hand-in-hand with Neasa Donnellan Architects and Dublin City Council, each element of the build was scrutinised for compliance of FSC, DAC, heritage protection and quality.

The work scope included full glazing replacement with all new sliding sash windows with slimlite double glazed panels in keeping with the original, full facade restoration and re-pointing, roof replacement, extensive structural works, removal of the existing basement slab and replacement with complete tanking system and new drainage and fire protection to existing staircore as per current regulations.

Internally the high-end office interiors include full power and data cabling and floor boxes throughout, bespoke joinery and panelling in every space, restored original Georgian features on all floors, newly landscaped rear yard, high quality floor finishes and a luxury, own door, 1-bed 2-bath self contained apartment in the basement.
