PLANS have been submitted to build a single room extension to the lower ground floor of a 150-year-old three-storey property in the Cockermouth area.

In addition the applicants are proposing to build a roof terrace over it, incorporate an outhouse into the dwelling and overcladding an existing extension at an address in Sunnyside in Papcastle.

It is proposed that the walls will be acrylic render on insulation batts and the roof will be a single ply membrane.

According to a heritage statement the proposed rear extension is described as "modest sized" and it will utilise an under used enclosed courtyard. It adds: "The property is not listed but is within the conservation area of Papcastle."

The report states the development will extend the existing flat roofed kitchen offshoot, to incorporate the external store/utility room, and over-clad the existing walls/roof of the offshoot to improve thermal performance.

It includes plans to install new wider patio doors to the kitchen and lower ground level adjacent to improve access and reduce damp ingress issues.

The report states: "The building is approximately 150 years old and extends over 3 storeys. It is in the Papcastle Conservation area.

"The dwelling appears only to have been extended once to provide a rear single storey kitchen extension. This appears to date from the 1960s but may be earlier.

"This existing extension has no real heritage value and is substantially hidden from public view. Behind this extension is a small, enclosed yard surrounded on all four sides with full storey height walls.

"The works are restricted to the enclosed yard and the single storey extension. The work to the kitchen extension is minimal with only the over-cladding work and patio door enlargement being visible to limited public view.

"All the other work is fully enclosed and blocked from view. This ensures the impact on the heritage area will be minimal to non-existent.

"Incorporating the lower ground enclosed yard and utilising its roof as a terrace will have no impact on the conservation area as no aspect of the proposal is visible from any public vantage point, or from neighbouring properties."

The application is being considered by planning officers at Cumberland Council.
