Richard Barrett's Bartra has received the green light for a new high-rise scheme of 200,000 sq ft (18,580 sq m) of office space at the Boston Sidings site in Dublin's Docklands.
This follows An Bord Pleanála upholding Dublin City Council's decision to grant planning permission for the 10-storey development in the Silicon Docks area of the capital.
Mr Barrett's group is developing the site at Grand Canal Quay and Macken Street in Dublin 2, in conjunction with site owner CIÉ.
The proposal came before the appeals board after local resident Paula Kinsella told the organisation that the height of 10 storeys overpowers the housing in Macken Villas and Macken Street generally.
She stated: "The overbearing height cannot be considered to balance with the residential zoning it adjoins."
Ms Kinsella also contended that the light study lodged along with the application "shows significant effects on a number of homes in Macken Villas".
However, the appeals board has given the plan the go-ahead, after it ruled that the proposal would accord with national strategic planning policy, local planning policies, and would not seriously injure the visual or residential amenities of the area, or adversely affect the development potential of adjoining land.
A submission to the appeals board on behalf of Mr Barrett's firm stated that construction stage procedures and design measures are to be implemented to safeguard residential amenities.
However, in a response submission lodged with the board last month by Ms Kinsella, she said that the quantum of development, and the scale, intensity and height, are too great, and that it is virtually impossible to protect the amenities of residential properties.
At the end of a 32-page report, however, board inspector Jane Dennehy recommended that planning permission be granted.
