Two unusual offices in Dublin are for sale and will soon be ready for occupation. The first, on Sir John Rogerson's Quay, is a 9,893 sq ft four-storey building available for renting at around £20 per sq ft. Although the building is designed for renting on a floor-by-floor basis, it's likely to be let to a single occupier.

Number 16 Sir John Rogerson's Quay is an infill development with glazing tilted out towards the river and "should suit someone looking for a flash office" according to Graham Farley of agents Farley Properties. "The facade of the office is inclined and hangs out between one and 1.5 metres over the path. As a result, all you see from inside is the river and you get the sensation that you could almost walk on the water," says architect John Smyth of O Muire Smyth (OMS) Architects, the building's designers.

Balconies, which are about 10 ft by 6 ft, are available on each floor and offer views to the Custom House and beyond in one direction and The Point and Dublin Port in the other.

The building also has raised access floors and suspended ceilings yet maintains a floor to ceiling height of at least 3.5 metres throughout. As a result, light penetration throughout the building is good.

There is a lift to all four floors and the office comes with six secure parking spaces. This £1.5 million building took around eight months to complete and its interior follows a modern minimalist design. It is situated on part of the large Richardson's Tiles residential site.

Mr Farley says it should be ready for occupation "in about six weeks" and "will be occupied by the end of the summer".

The second office is on Beresford Street close to the Four Courts. It forms part of a converted grain store development of 176 apartments and is situated in a double-height triple-vaulted space of 2,085 sq ft, including a mezzanine level. Rent is expected to be in excess of £16 per sq ft and the building cost around £150,000 to refurbish.

Its structure of large cast-iron columns and beams has been retained, as have the triple-vaulted ceilings. Oak flooring prevails throughout and the basement contains toilets and a storage area. It also has five secure parking spaces.

Although close to the HARP area, the office doesn't come with tax reliefs.

"I've had over 100 inquiries for these two offices and my legs have been practically walked off me bringing clients around to look at them," says Mr Farley.
