Novel model for urban development
Project in brief
22 Clyde Road is a designated
Protected Structure, and is the headquarters of Engineers
Ireland (the operating name of The
Institution of Engineers of Ireland) who represent the
interests of more than twenty-one
thousand professional engineers in Ireland.
The original building was linked to a modern
lecture theatre building situated at the rear.
The client required additional office space, archive storage and upgraded lecture facilities.
The project was defined by a decision to move the lecture theatre from its old first floor location to a new embedded position below the garden. Another floor was added to the old lecture theatre building and two floors of offices were installed over the retained conference room. In conjunction with the above, it was decided to create a new Archive Building.

Key features
The first part of the work was the
most radical and difficult to
undertake - to excavate the garden,
place the new lecture theatre under
it and replant overhead, creating a
new garden. To carry out this work,
the entire inner façade of the original
lecture theatre building was removed
to expose the structure; this was
underpinned and the garden area
excavated and lined with silent
vibrated sheet piles. A new angled
steel structure was installed against
the original façade with extensive
services located between the earth
roof and the internal lining of the
lecture theatre.
The "green roof surface" extended from the ground at an angle and turned up the wall, creating additional space at first floor and a location for a lift behind it. Earth was infilled above the lecture theatre, a grid of tensioned cables strapped across it and the timber surface - providing a field that will become green and dense with foliage.
The building, the first of its type in Dublin has been recommended as an innovative model for inner city development on tight urban sites.
