Officer report
The site
The site is vacant green space north of James Street, beside trees and existing two-storey terraced homes.
“Location: The development site is located on a parcel of vacant land to the north of James Street, in Trethomas.”
“Site description: The site is an undeveloped section of green space to the north of James Street. The land sits to the south of a portion of trees of varying maturity. The site fronts onto three streets, with four rows of two storey terraced dwellings, with a further three properties being located to the north east of the site, being accessed off Glyn Street.”
Officer report
Why officers supported it
Officers considered the amended boundary treatment resolved earlier design concerns and found the proposal acceptable subject to conditions.
“The primary issue therefore that required to be addressed was the front boundary treatment and the resultant inactive edge that this would lead to, fronting onto the primary provision of open space within the scheme.”
“It is however acknowledged that there are several planning conditions on the outline consent that would impact the design of the development, namely condition 15 for boundary treatments and condition 16 for a hard and soft landscaping scheme, neither of which will be discharged within this submission and as such will be secured within the necessary subsequent discharge of conditions applications, or alternatively the further required reserved matter - scale.”
Officer report
Main planning issues
Officers assessed design, landscaping, open space, drainage, residential amenity, affordable housing and highways.
“Policy CW7 relates to the Protection of Open Space and states that proposals for development on areas of open space within settlements will only be permitted where: A. The amount of open space remaining in the neighbourhood would still be adequate to serve local needs. B. The site has no significant value as a recreational resource or an area of visual amenity.”
“Where there is evidence of need, the Council will seek to negotiate the following affordable housing targets of:40% of the total number of dwellings proposed on sites within the Caerphilly Basin (excluding Aber Valley). Due to the nature of the development, the scheme is 100% affordable and therefore, it complies with the affordable housing target of the area.”
Officer report
