DUBLIN agent Drums is inviting offers about £170,000 for Clonshaugh House, which is surrounded on three sides by Clonshaugh Industrial Estate near Coolock in Dublin 17. The 30-year-old building stands on half an acre of grounds, which are zoned for light industrial developments. The agency says that apart from a family home, the house would also be ideal as a doctor's surgery, creche or an administrative centre.
