One of Dublin's most desirable office blocks has been put on the market this morning with an asking price of €163.8m - making it the most expensive office block to come on the market since the end of the Celtic Tiger.

Property advisers CBRE and JLL have been named as agents for the sale of 4 Grand Canal Square along with 5 Grand Canal Square that is also rented by Facebook under a separate lease.

The two buildings house the tech company's headquarters for Europe, Africa and the Middle East and is Facebook's biggest operation outside of the United States.

The social network moved into the premises earlier this year and the fact that a successful and globally recognised company is renting the building makes it a more attractive prospect for potential buyers. There are rumours that Facebook could be tempted to purchase the office space.

One of Ireland's largest property developers Chartered Land has put the premises on the market - having previously been behind both Grand Canal Square and Dundrum Town Centre - and is currently working with the National Asset Management Agency (NAMA).

Other assets going on the market include Alexandra House, 86-88 Lower Leeson Street and One Grand Parade.

The sale is part of NAMA's plan to sell €250 million worth of assets in every quarter, taking advantage of the current recovery in the commercial property market.
