R-House, Galway City.

This 1990 built city centre dwelling has been transformed from a
dark single-storey residence with two bedrooms, to a modern light-
filled two-storey family home with four bedrooms. In addition,
through the use of modern insulation methods and a state of the art
Air-to-Water heat pump, the energy rating has been improved from
an F to a B2 rating. The retention of the main structure as part of
the retrofit ensured that nuisance in this tight pedestrianised area
was minimised and most of the embodied energy in its initial
construction was retained.
