If Ryanair manages to secure the guideline price of £10 million for an office block it is selling beside the Phoenix Park on Conyngham Road in Dublin 8, it is likely to be one of the property deals of the year. The airline bought the former Sullivan Bluth building about four years ago for £2.2 million after it had been unoccupied for a considerable time. Phoenix House, the 36,000 sq ft building, has now been let on new 25-year leases to Ryanair and the Office of Public Works at a combined rent of £531,000 per annum. Ryanair has a break option in 2011 and the OPW can opt out in 2009. It is, perhaps, no great surprise that Ryanair has opted to cash in on Dublin's property boom and free up funds for capital investments. The company bought the block when there was little demand for vacant buildings in secondary locations. It has since put it to good use, locating a call centre on three of the five floors. A section of the Department of Justice is to occupy the other two floors. The 56 on-site car parking spaces are to be shared. The selling agent is DTZ Sherry FitzGerald.
