1.0 THE SITE - 1.1 The site is the residential curtilage of 6 Bank Street, Castletown, a three storey midterraced dwelling in Castletown, within the town's Conservation Area. The property has a pitched roof, with chimney stacks on each of the party walls, and painted render walls. - 1.2 The property has three windows to the first and second floor front elevation and two windows on the left of the main entrance door on the ground floor. The windows on the front elevation of the property are sliding sash windows, while the windows on the side elevation, as well as the windows on the first and second floor rear elevations are sliding sash windows. The only windows that are not sliding sash windows on this property are the kitchen window and the smaller widow on the two storey rear extension, which have casement windows. All the windows have Georgian Bars, while the door is part-glazed. - 1.3 At the rear of the dwelling is a rear yard which is enclosed by the rear yard with walls that are about 4m high at the lowest point with the first and second floor windows afforded views to Castle Rushen at the rear and over the enclosed walled garden of 16 Malew Street which has a large walled garden abutting Castle Rushen. This neighbouring walled garden has significant tree cover on most parts of the garden covering over 50 percent of the garden. - 1.4 Within the rear yard is an existing outbuilding which comprises two stores and a WC. Recent photos of the rear yard obtained from the applicants, however, show that the outbuilding has been demolished with the area cleared.
2.0 THE PROPOSAL - 2.1 The application seeks planning approval for creation of sunroom and terrace to rear yard and replacement of existing windows and doors. - 2.2 The works proposed would include:
3.1 The site lies within a Mixed Use area on the Area Plan for the South adopted in 2013 and also within Castletown's Conservation Area where Planning Policy Statement 1/01 requires development to preserve or enhance the character or appearance of the area and to take into account in any decision, the special character of the area. The site is not prone to flood risk and the site is also not within a Registered Tree Area, and there are no protected trees on site. As such, the following Strategic Plan policies are relevant:
3.2 General Policy 2: Development which is in accordance with the land-use zoning and proposals in the appropriate Area Plan and with other policies of this Strategic Plan will normally be permitted, provided that the development:
3.3 Strategic Policy 4: Proposals for development must: (a) Protect or enhance the fabric and setting of Ancient Monuments, Registered Buildings(1), Conservation Areas(2), buildings and structures within National Heritage Areas and sites of archaeological interest; - 3.4 Environment Policy 35: Within Conservation Areas, the Department will permit only development which would preserve or enhance the character or appearance of the Area, and will ensure that the special features contributing to the character and quality are protected against inappropriate development. - 3.5 Environment Policy 34 expresses a preference for the use of traditional materials in the maintenance, extension or alteration of pre-1920 buildings.
4.1 TOWN AND COUNTRY PLANNING ACT 1999 S18 Designation of conservation areas Section 18(4) of the Town and Country Planning Act (1999) states, "(4) Where any area is for the time being a conservation area, special attention shall be paid to the desirability of preserving or enhancing its character or appearance in the exercise, with respect to any buildings or other land in the area, of any powers under this Act".
4.2 Planning Policy Statement 1/01 "POLICY CA/2: SPECIAL PLANNING CONSIDERATIONS When considering proposals for the possible development of any land or buildings which fall within the conservation area, the impact of such proposals upon the special character of the area, will be a material consideration when assessing the application. Where a development is proposed for land which, although not within the boundaries of the conservation area, would affect its context or setting, or views into or out of the area; such issues should be given
Planning Circular 1/98, the Alteration and Replacement of Windows Category (b) BUILDINGS IN CONSERVATION AREAS "If the original windows are in place they should preferably be repaired. If repair is impracticable, replacement windows which would be readily visible from a public thoroughfare MUST HAVE THE SAME method of opening as the originals. Whatever the material used in their construction, the windows MUST HAVE THE SAME pattern and section of glazing bars and the same frame sections as the original windows.
Windows not readily visible from a public thoroughfare must have the same or similar pattern of glazing bars as the original method of opening, whatever the material used in the construction."
4.4 Whilst not adopted planning policy, DEFA's Residential Design Guidance is a material consideration in the assessment of this application as, "It is intended to apply to any residential development within existing villages and towns, including individual houses, conversions and householder extensions". Sections 2.0 on sustainable construction, and 7.0 which deals with impact on neighbouring properties, are considered relevant to the current scheme.
5.1 The site has been the subject of five previous planning application, two of which are considered to be materially relevant to the current application.
5.2 PA 84/00108/B for alterations and extensions to convert plumbers store to cafe/tearooms with living accommodation over, and PA 91/00761/B for external remedial alterations (Both approved). These have resulted in the current appearance of the dwelling which the current application seeks to alter. - 6.0 REPRESENTATIONS Copies of representations received can be viewed on the Government's website. This report contains summaries only.
6.1 Representation from the Department of Infrastructure (DOI) Highways Division confirmed that they 'Do not oppose' in a letter dated 26 August 2021. Having reviewed the amended plans submitted by the applicants, they continue to not oppose this proposal as stated in an email dated 14 September 2021.
6.2 There has been no written representation made regarding the current planning application by the Castletown Commissioners at the time of writing this report, although they were consulted on 12 August 2021 and 13 September 2021.
6.3 The owners/occupiers of 4 Bank Street, Castletown have stated that they object to the applicant on the following grounds (28 August 2021):
]6.3.1 Having reviewed the comments by this neighbour, the applicants have submitted amended plans to remove the sun terrace from the proposal.
7.1 The assessment of the current application will be two fold; evaluating the impact of the proposed extension on the property, Conservation Area and neighbouring dwellings, and assessing whether the proposed window replacements would meet the test set out in Environment Policy 35 and Planning Policy 1/98 for preserving or enhancing the Conservation Area.
7.2 Environment Policy 35 sets out the policy in regards to development within a Conservation Area. The policy states that development would only be permitted within a Conservation Area if the development would preserve or enhance the character or appearance of the area as the area is protected against inappropriate development.
7.3 With regard to the works related to the replacement of the existing windows, it can be argued that windows are the most important element in a facade. They can confirm the style, age or even the purpose of a building. As such, the original windows should be replicated faithfully in opening method and glazing bar pattern, particularly in situations where the windows can be viewed from public vantage points within the street scene (such as the front elevation, the first and second floor rear elevation, and side elevation). In view of the fact that the dominant window type on Bank Street is the traditional sliding sash windows, what is proposed would fit seamlessly into the character of the street scene. Whilst the replacement windows proposed under this scheme would be UPVC sliding sash windows, they would have a similar appearance to the timber sliding sash windows on the property, with similar patterns of glazing bars.
7.4 It is also considered that the use of UPVC is not uncommon within the Castletown Conservation Area as a whole since newer sliding sash installations are mostly UPVC. On assessment, it is deemed that the proposed windows would not be detrimental or harmful to the character and quality of the locality but would preserve the character of the existing streetscene and Conservation Area.
7.5 The works at the rear of the building to replace the existing timber casement windows with UPVC sliding sash windows are also considered to be an acceptable development. This is hinged on the fact that the design and finishing would be an improvement on the existing casement windows given that it would create a uniform window appearance for the whole of the property. Based on the foregoing, it is considered that the proposed replacement windows, whilst made of UPVC material will preserve the appearance of the existing building and Conservation Area, as well as contribute positively to the energy efficiency of the application dwelling. - 7.6 Overall, it is noted that the degree of flexibility in the material used for replacement
7.7 In assessing the impact of the proposed installation of the UPVC half glazed external door on the front elevation, as well as the introduction of new windows on the second floor side elevation and first floor rear elevation, it is considered that these would not detract from
the character of the existing property, locality and Conservation Area. The fact that the new windows and replacement door would mirror the existing on the property would ensure that these are seamlessly integrated into the existing building. Besides, the proposed door and windows would be double glazed and their design and finishing would be in keeping with the existing, with the new windows offering better energy efficiency standards. It is also considered that the works to the rear would be within an enclosed rear yard, with the new
7.8 With regard to the proposed works to erect the single storey flat roofed rear extension which would replace the existing outbuilding within the rear yard, it is considered that the extension replaces an existing part of the building, and is bounded by higher walls which would limit views to the proposed works. Whilst it would have been more appropriate for the new extension to have a roof pattern that would mirror the roof pitch and slope of the main dwelling, the flat roof would be positioned at the rear and would be completely enclosed by the walls of the rear yard with its roof structure ensuring that the key features of the main dwelling are not obscured by the addition of the extension; thus appearing as a contemporary but subordinate addition to the dwelling. Based on the foregoing, it is considered that there would not be a negative impact on the existing dwelling, and as such, this element of the proposal is considered to comply with General Policy 2 and Environment Policy 35 of the Strategic Plan. - 7.9 In terms of impacts of the proposed works on neighbouring dwellings, it is considered that the new windows are the elements that have the potential to most likely to impact on neighbours. This is hinged on the fact that they would introduce new fenestrations with views to neighbouring properties. However, the setting of the locality is such that views are attainable at first and second floor level to the rear of neighbouring properties, resulting in mutual overlooking at this level. It is also noted that the position of the new bifold door on the rear extension will not introduce any detrimental impacts on neighbouring amenity since it would be enclosed by the rear yard. Therefore, the proposed works would not result in detrimental impacts on the neighbouring properties and as such is deemed acceptable.
8.1 For the reasons given, the proposals is considered to comply with the relevant polices of the Strategic Plan and Planning Circular 1/98, and the Residential Design Guide 2021, and therefore recommended for approval. - 9.0 INTERESTED PERSON STATUS
