A state of the art Mitsubishi Electric'EcoDan'  air to water heat pump unit, installed on the grounds of a recent new build, which will keep the whole building cosy throughout the year, at next to no cost.  And of course such installations can avail of the generous SEAI grants for heat pumps and other energy conservation measures.

- Renovations and refurbishment
   Clients frequently wish to renovate an existing property.  We can
   work with you either to carry out extensive renovations to that
   property or to modernise the existing building while retaining its
   original charm and features.  Alternatively, we can deliver effective
   repairs to your existing property.

- Extensions
   We can work with you to plan and build extensions to your home,
   such as conservatories/sunrooms, or additional rooms and
   facilities to accommodate the needs of a growing or an ageing
   family unit.

- Commercial and Public Sector contracts
   Our clients/services include public sector or commercial work.  For
   example, we recently carried out extensive refurbishment work for
   the Department of Education, on a local school.  Bord Iascaigh
   Mheara entrusted a sensitive demolition project to McDonnell
   Construction, removing a disused ice plant building located in an
   area of some complexity.

The old ice plant at Cleggan Harbour, owned by Bord Iascaigh Mheara, had lain derelict for many years.
Situated right at the edge of the Inner Basin, and originally built from mass concrete and pre-stressed steel.
its demolition called for careful planning and detailed liaison with both the client and with Galway County Council.  The work was completed within budget and on time.  The visual improvement arising from this work is plain to see.
