- the construction and operation of a wellness facility incorporating 2no. sauna cabins, 4 no. cold plunge tubs, 2no. changing area, 1no. WC, reception area, maintenance yard and associated ancillary structures - Installation of wastewater treatment facilities and all associated site works - Provision of 14no. car parking, 8no. bicycle parking, signage, landscaping, boundary treatments and connection to existing services - And all ancillary and associated development works above and below ground

extension of permission for planning ref 12/1002: an electrical transmission substation and associated infrastructure and works, within and adjacent to the site of the existing 220/110kV Killonan substation. The development consists of (1) construction of a 220kV Gas Insulated Switchgear (GIS) substation building, of 1,856m2 gross floor area, with a maximum height of approximately 14 metres above ground level, (2) construction of a 110kV GIS substation building of 1,642m2 gross floor area, with a maximum height of approximately 12.5 metres above ground level, (3) construction of associated and ancillary outdoor electrical equipment and other apparatus; construction of three lightning masts of approximately 18.4 metres in height; internal access road, car parking areas, boundary treatment, associated drainage and site development works, (4) associated transfer of circuits from the existing 220/110kV Air Insulated Switchgear (AIS) substation to the proposed GIS substation, (5) construction of six 110kV end masts to facilitate connection of the existing overhead line transmission circuits to the proposed substation equipment by way of underground cable connections. These end masts will replace six existing end masts which are located within the existing ESB Killonan site. Two of the six end masts will be located adjacent to, but outside the western and southern boundaries of the existing substation complex. One of these two end masts will be located in the townland of Coolyhenan, the other will be in the townland of Milltown. The remaining 4 end masts and all other proposed works are located within the existing ESB Killonan substation in the townland of Milltown. The proposed end masts will measure up to a maximum of 21.5metres in height and will be of a similar form, scale and character to those existing and (6) all associated site development works (this application is for a 10 year permission)

the construction of an extension to an existing dwelling, new septic tank, percolation area and all associated site works

conversion, alteration and enlargement of 2 no. existing residential units (granted planning permission under 18-293) into one single residential unit, consisting of 4 no. bedrooms including all ancillary site works. Planning permission for effluent treatment and vehicular entrance has already been granted under 18-293 for a similar type development. The proposed development is necessary in order to upgrade the current minimal standards of living accommodation in accordance with more appropriate sustainable urban housing design standards for such accommodation

minor modifications to a previously permitted development (Ref. 12/1002). The proposed development comprises the extension of the existing Killonan 220/110 kV Electrical Substation compound by approx. 0.5ha along and adjacent to its existing western boundary. This will facilitate the proposed siting of a previously permitted Line Cable Interface Mast (LCIM) development includes the associated erection of 2.6m high palisade fencing along the extended western boundary of the substation compound and all associated and ancillary development at the existing Killonan 220/110 kV Electrical Substation

(a) the amalgamation of 2 no. existing residential units (granted retention permission under 18/293) into one single 2 bed residential unit and (b) construction of a new residential unit consisting of an extension to same. Planning permission for effluent treatment system and vehicular entrance has been granted under 18/293. The proposed development is necessary in order to upgrade the current minimum standards of living accommodation in accordance with more appropriate sustainable urban housing design standards for such accommodation
