Dublin property developer Tony Murray who made a successful switch from housing to industrial parks in recent years now has his own hotel to entertain his clients. Last week he opened Johnstown House and Spa, a £30 million venture in the busy 'en route' village of Enfield. The complex is based on a Georgian home set among 70 acres of Meath pasture land. All 124 bedrooms have under floor heating, a feature that is likely to be copied by other new hotels.
