Restoration of flagship office development on St. Stephen's Green
Project in brief
These two neighbouring Georgian
buildings occupy a prominent
position on St. Stephen's Green, and
are designated Protected Structures.
Formerly occupied by the Office of
Public Works, they are owned by
Dublin City Council and were
renovated as a flagship office
development. The project was
featured in National Heritage Week
(2002) with a guided tour of work in
progress, which proved to be very
popular with the general public.
The building is a four storey structure over basement comprising external and internal load-bearing masonry walls, slated timber doublepitched roof, timber floors and stairs. The property also included two large derelict Mews buildings, which were stabilised by structural remedial work.
The refurbishment contract included the repair of defective masonry, the repair or replacement of degraded structural timber, and the replacement of prominent façade ties with concealed structural ties.

Key features
Bowed front wall
The front wall, which was
precariously bowed-out towards the
Green, was surveyed to produce a
three-dimensional contour survey in
order to assess its stability. The wall
was then stabilised by stitching back
to each floor with customised
chemical anchors. This also enabled
us to remove the existing tie bars and
plates and improve its appearance.
Air raid shelter
The basement under No. 14 had
been developed as an Air Raid
Shelter during the Emergency, and
the wartime structural modifications
were carefully reversed to restore
the original character of the building.
Strengthening
The strength of the historical timber
floors was assessed for the intended
usage, and locally strengthened to
accommodate new chandeliers.
Restoration
Cracked masonry was carefully stitched together to restore structural integrity, and un-bonded cross walls were bonded to the façade using concealed fixings.
Historical Renovation
At LeeMcCullough we have
exceptional experience of revitalising
existing buildings, which is often more
complex than the structural
engineering of new buildings.
Over many projects we have addressed and resolved a wide range of issues, including:
- Strengthening historical joists and beams to carry increased loading
- Masonry Decay/Delamination
- Threading modern services into old structures
At LeeMcCullough we always seek to identify and resolve issues early, innovatively address demanding building difficulties and deliver our solutions on time and cost efficiently.
When it comes to renovation and refurbishment, anticipating and resolving engineering issues effectively is the key to a successful outcome.
