28, Arbory Street, Castletown, Isle Of Man, IM9 1lj
Permission was granted to convert a three-storey stone-built retail and office building at 28 Arbory Street, Castletown into a single residential unit. The building sits on the north side of Arbory Street in the town centre, within the Castletown Conservation Area, and has a rear car port accessed through an archway capable of accommodating three cars. The surrounding area is a mix of commercial, office, and residential uses in terraced buildings of three to four storeys. The officer considered the principle of the change of use, the potential visual impact on the Conservation Area, effects on neighbouring amenity, and traffic and highway matters. The application was approved by delegated decision on 5 September 2025, with one condition attached.
The Department of Environment, Food and Agriculture approved the application on 5 September 2025. Key issues considered included the principle of the change of use, the visual impact on the Castletown Conservation Area, and the effect on neighbouring residents' amenity. One condition was attached to the permission.

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; (b) protect or enhance the landscape quality and nature conservation value of urban as well as rural areas but especially in respect to development adjacent to Areas of Special Scientific Interest and other designations; and (c) not cause or lead to unacceptable environmental pollution or disturbance. 4.3.8 The design of new development can make a positive contribution to the character and appearance of the Island. Recent development has often been criticised for its similarity to developments across the Island and elsewhere - "anywhere" architecture. At the same time some criticise current practice to retain traditional or vernacular designs. As is often the case the truth lies somewhere between the two extremes. All too often proposals for new developments have not taken into account a proper analysis of their context in terms of siting, layout, scale, materials and other factors. At the same time a slavish following of past design idioms, evolved for earlier lifestyles can produce buildings which do not reflect twenty first century lifestyles including accessibility and energy conservation. While there is often a consensus about what constitutes good and poor design, it is notoriously difficult to define or prescribe. 4.3.9 The Department recognises the need to raise the quality of the Island's architecture and built environment and is pursuing this through the development control process and the commissioning of its own schemes and environmental improvements. At the same ti me it appreciates that the debate about good design needs to be broadened to include those who design, construct and finance new development and the wider community as we are all affected by the end product. To this end it welcomes the Isle of Man Arts Co uncil's National Arts Development Strategy 2005 - 2014 which has as one of its objectives, to raise the quality of the Island's architecture and built environment by encouraging debate on architectural standards, town and country planning, urban regenerati on and public art. This Strategy recognises that debate will have to take place over time. 4.3.10 In the meantime, the Department considers that, while there are a number of policies in the Strategic Plan which cover various elements of the design of new development e.g. General Policy 2 (a) -(i), ( m) and (n), and various Housing policies, there is a need for a further statement on the need to secure quality in the design of new development. In the preparation of Area Plans the Department will include development briefs that set out design principles for significant sites including new residential areas. Subsequent planning applications will be required to be accompanied by a Design Statement setting out the way in which the proposal has been designed to take into account its context and how the design principles have been developed. 4.3.11 At the same time as wishing to promote good design in new development the Department recognises that there are an increasing number of alternative styles of housing which draw their design principles from the wish to promote sustainability and energy efficiency. Many of these can be incorporated into both modern and traditional designs but in some cases they produce a completely different structure or form of buildings, for exa mple underground (1)Registered Building is defined in Appendix 1 (2) Conservation Area is defined in Appendix 1 housing. While wishing to conserve the historic landscape of the Island the Department welcomes new styles of housing as long as they take into account the landscape context and the impact on the amenities of the area in which they are si ted. Merely arguing that a new building cannot be seen in public views is not a justification for the relaxation of other policies relating to the location of new development.
Spatial Policy 5
accords with the provisions of Policies ST2, ST3, ST4, ST5, SP4, SP5
Strategic Policy 5: New development, including individual buildings, should be designed so as to make a positive contribution to the environment of the Island. In appropriate cases the Department will require planning applications to be supported by a Design Statement which will be required to take account of the Strategic Aim and Policies. 4.4 Economy 4.4.1 The Spatial Strategy identifies the Major Employment Areas around the Island. While the majority of business and employment is focused around the Douglas Metropolitan Area, there are other major employment areas at Castletown, the Airport/Freeport, Peel, Ramsey and Jurby. The Department considers the distribution of employment areas provides a spread of employment opportunities around the Island. While recognising the opportunities for small scale local employment within existing centres it is considered new employment should, in the main, be concentrated within existing settlements or those major employment areas referred to in the Island Spatial Strategy and illustrated on the Key Diagram. Existing Local and new Area Plans will provide detailed boundar ies for these areas. From time to time Government may judge it appropriate to offer financial incentives to encourage economic activity or investment in particular parts of the Island.

mals or other legitimate agricultural purposes. Where those buildings or developments are proposed close to existing watercourses, such developments should be carefully scrutinised and advice sough1t from DAFF where appropriate and clarification provided of the proposed, possible and likely nature of the use of the proposed building as this can affect the impact of the development on the water course.

Environment Policy 23
Environment Policy 23: When considering alterations and improvements to existing facilities the Department will require that consideration be given to the potential adverse impact of the proposed changes to existing neighbours. 7.18 Environmental Impact Assessment(1) 7.18.1 Environmental Impact Assessment (EIA) is an important procedure for ensuring that the likely effects of new development on the environment are fully understood and taken into account before the development is allowed to go ahead. It is a process by which information about the likely environmental effects of certain types of development is collected, assessed and taken into account by the developer (as part of project design) and by the planning authority (in determining the acceptability of the application). In cases w here developments are likely to have significant environmental effects, whether public or private, by virtue of their nature, size or location, EIA's will be required and the general principles set out in Appendix 5 should be followed. 7.18.2 For some types of development, EIA's will be required in every case, whilst other development will only require an EIA if the particular project is judged likely to give rise to significant environmental effects. Where development does not fall wit hin these categories, (1) Environmental Impact Assessment is defined in Appendix 1 but still has a significant effect on the environment, the Department will require suitable supporting environmental information. The main criteria for judging significance are as follows: i. major developments which are of more than local importance; ii. developments which are proposed in particularly environmentally sensitive or vulnerable locations; iii. developments with unusually complex and potentially hazardous environmental effects. 7.18.3 A Planning Policy Statement will be issue d specifying the manner in which the Department intends to deal with applications which should be subject to EIA. Pending the adoption of the proposed Planning Policy Statement the Department will adopt current practice on EIA's from England and Wales set out in the publication "Environmental Impact Assessment: A Guide to Procedures" (1).
Environment Policy 35
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. 7.30 Development adjacent to Conservation Areas 7.30.1 It is often the case that important views into and out of a Conservation Area can contribute significantly to its character. It is necessary to assess the impact any development adjacent to conservation areas may have on such views.
