Three Georgian buildings on Merrion Square, combining pristine period accommodation and modern office space, are available to let in one unit through Jones Lang LaSalle on behalf of the present occupants, IIB Bank.

Numbers 91, 92 and 93 are located on Merrion Square West, beside the National Gallery and Leinster House.

Numbers 91 and 92 are to let by assignment of the existing lease while Number 93 is to let or for sale: however, as all three are interconnected they are available only as one unit.

Number 91 and 92 have been maintained in pristine condition and have a modern extension at the rear. They have a passenger lift, fire alarm system and air conditioning in the mews extension.

Accommodation comprises 997 sq m (10,731 sq ft) over five floors and car-parking at the rear for 17 cars.

The properties are held under a 35-year lease dating from 1982 and expiring in 2017. The current rent is €400,000 per annum and the lease provides for five-yearly rent reviews to 85 per cent of the open market value.

Number 93 is freehold and available either to buy or to let. It has 559 sq m (6,017 sq ft) of accommodation over its five floors as well as ample car-parking at the rear.

"These buildings would make an ideal corporate headquarters, as they have done for IIB Bank, because of their rare mix of the prestigious Georgian and the flexible modern," says Deirdre Costello of Jones Lang LaSalle, who is handling the lettings and/or sale.

"Their location at the heart of the city's traditional central business and administrative district is ideal for everyone from employees to visitors."
