Thurlby Cottage, Ballagawne, Ballabeg, Castletown, Isle Of Man, IM9 4hl
The application sought permission to alter and extend an existing dwelling and erect a detached garage at Thurlby Cottage, Ballagawne, Ballabeg. The site is a detached traditional stone-built crofter's cottage set within approximately one acre of grounds, with its boundaries largely enclosed by mature trees, shrubs, and a Manx stone wall. A previous approval for a garage lapsed in 2014 and was never built, leaving the property without one. The main planning issues were the principle of extending a rural dwelling, visual impact on the countryside, effects on trees, ecological impact, and impact on neighbours. Officers found the extension would be set back around 8.1 metres from the highway, with existing boundary trees screening most of it from public view. The proposal was judged to represent an improvement in design quality over the existing extensions, with no significant harm to public or private amenity, the countryside, or landscape character.
The Planning Committee approved the application because it was found to cause no significant harm to the landscape, countryside character, or neighbouring amenity, and would result in a design improvement over the existing dwelling. The mature boundary trees and stone wall were considered sufficient to screen the extension from the highway. The proposal complied with Housing Policy 15 and Environment Policies 1, 3, and 4 of the Isle of Man Strategic Plan 2016.
Housing Policy 15
Housing Policy 15: The extension or alteration of existing traditionally styled properties in the countryside will normally only be approved where these respect the proportion, form and appearance of the existing property. Only exceptionally will permission be granted for extensions which measure more than 50% of the existing building in terms of floor space (measured externally).
Environment Policy 1
Area Plan for the East sets out locally-applicable means for implementing the policies set out in the Isle of Man Strategic Plan 2016. In that Strategic Plan, we find the Environment Policies. Environment Policy 1 states: The countryside and its ecology will be protected for its own sake. For the purposes of this policy, the countryside comprises all land which is outside the settlements defined in Appendix 3 at A.3.6 or which is not designated for future development on an Area Plan. Development which would adversely affect the countryside will not be permitted unless there is an over- riding national need in land use planning terms which outweighs the requirement to protect these areas and for which there is no reasonable and acceptable alternative. Maintaining the purpose of this Area Plan as a means of implementation, there is some further direction to be found in the Strategic Plan, at paragraph 7.2.1: 'Whilst landscape and coastal change is inevitable, and in some cases desirable, the emphasis must be on the appropriateness of this change and the balance or equity between the needs of conservation and those of development. The primary goal must therefore be to respect, maintain and enhance the natural and cultural environment including nature conservation and landscape and coastal quality, and ensure its protection from inappropriate development.' Given the comprehensive nature of the Isle of Man Strategic Plan's Environmental Policies, only a small number of additional Proposals and Recommendations are necessary. In order to produce an implementable Area Plan for the East it is necessary to recognise those statutory desig nations and strategies which whilst having an Island-wide scope are highly relevant to the protection of environments within the Plan Area. An example is the UNESCO Biosphere status afforded to the Isle of Man. Island-level strategies identify crossborder issues and take account of the cumulative impacts of human engagement with nature. Area Plan Objectives i. To protect, conserve and enhance the natural and cultural environment of the plan area and promote biodiversity. ii. To improve the function, usability and provision of our green infrastructure and public spaces by providing a network of green spaces and features which are connected and where possible, accessible to the public. iii. To manage and improve flood risk and improve drainage conditions. iv. To support the working countryside and its custodians in maintaini ng a sustainable rural economy. Area Plan Desired Outcomes i. Where approved, d evelopment will be ecologically sustainable and designed to protect and where possible enhance biodiversity as well as mitigate and adapt to the effects of climate change. ii. The Green Infrastructure network will be established and fostered, connecting people with nature in a way that achieves the best shared outcomes for the urban and natural environment. iii. Statutory and non-statutory designations will continue to provide protection to the most important and most vulnerable cultural assets, habitats and environments in the plan area. iv. Beyond the towns and villages, the area as a whole will retain its landscape setting including its important visual interaction with the central uplands, central valley, coast and marine environment. Natural Environment Proposal 1 The Department supports the protection, creation and improvement of green infrastructure in the East, particularly in those locations which have the potential to be part of a Green Infrastructure Network. Applications for development must take into account any approved Government Green Infrastructure Strategies, but in any case, must identify how development proposals intend to contribute to the long term provision of a network of connected green spaces. UNESCO Biosphere In 2017, the Isle of Man became the first ever entire nation to achieve UNESCO Biosphere status. Project partners pledge to take steps to protect natural resources, develop the economy in a sustainable way and promote outstanding living landscapes. UNESCO Biosphere Reserves are established to connect people and the economy with nature, wildlife, culture, heritage and communities. Biosphere Reserves have three functions: Conservation: to contribute to the conservation of landscapes, ecosystems, species and genetic variation. Development: to foster economic and human development which is socio -culturally and ecologically sustainable. Logistic support: to support demonstration projects, environmental education and training, research and monitoring related to local, regional, national and global issues of conservation and sustainable development. The Isle of Man Biosphere is zoned into six areas . Examples of all of these can be found in the Eastern area: Terrestrial Core areas, Marine Core areas, Terrestrial Buffer zone, Marine Buffer zone, Terrestrial Transition areas and Marine Transition areas. There is some overlap with The Isle of Man's First Biodiversity Strategy 2015-20
Environment Policy 3
Environment Policy 3: Development will not be permitted where it would result in the unacceptable loss of or damage to woodland areas
ar sea views. Additionally, services for networked water supply and other essential utilities would be difficult to provide for additional development in this area (see Maps 3, 7 and 9). Natural Environment Proposal 3 (Green Gap) Between the settlements of Laxey and Baldrine, development which would erode the separation and detract from the openness between the settlements will not be supported. Glen Vine and Crosby - These two settlements, although proximate in location, are separate and distinct in many ways. Consultation has clearly demonstrated this through the views expressed during the stages of plan development. In cases such as this, the breaks in the urban fabric and the features of nature which provide a sense of openness should be protected from development which would erode this (see Maps 3 and 10). Natural Environment Proposal 4 (Green Gap) Between the settlements of Glen Vine and Crosby, development which would erode the separation and detract from the openness between the settlements is unlikely to be supported. Douglas, Union Mills and Strang (see Maps 3, 4 and 8) Natural Environment Proposal 5 (Green Gap) Between the settlements of and Douglas, Union Mills and Strang, development which would erode the separation and detract from the openness between the settlements is unlikely to be supported. The Upland Environment The Manx Uplands are an iconic part of our landscape and heritage. Reference to the 'sweet mountain air' and 'green hills and rocks' are enshrined in our national anthem and the colours of the heather and gorse are woven into the very fabric of Manx tartan. The hills are a place of great beauty, yet for some they are also a place to work and for others a place to exercise or simply enjoy open space. Our Uplands are also home to plants and animals that whilst familiar to us, are rare and impor tant in a global and European context. Furthermore, the uplands are a rich repository of cultural and archaeological remains, which are sensitive to change and can easily be damaged by inappropriate development. Production of food is an important and obvi ous function of hill land. But surprisingly, the Manx hills provide everyday functions that most people take for granted. Peatlands, which cover most of our hills reduce the impacts of climate change by locking up carbon dioxide, collect and filter our drinking water and slow the passage of rainfall into streams and rivers, thus reducing downstream flood risk. These multiple uses are of great benefit to the economy of the Isle of Man and the well - being of its people. It is important that the hills continue to provide these benefits long into the future. Ensuring sustainable management of such a wide range of uses to the satisfaction of all interested parties whilst retaining functions essential to the well -being of the Isle of Man is of paramount importance. The Isle of Man Government is the owner and landlord for the majority of the Uplands in the East region and is therefore in a position to implement policy which will deliver the optimum range of ecosystem services. Appropriate and positive Upland management such as controlled rotational burning/cutting of heather and low intensity grazing helps to reduce the fuel load of the hill, provides firebreaks and reduces the risk of unplanned wildfires that further protects the biodiversity of the site, but also the vast amounts of carbon locked away in the peat soils. The majority of this work is carried out by The Department of Environment, Food & Agriculture's grazing and shooting tenants. The Manx Uplands are critically important from a habitat and biodiversity perspective. The hills in the East support a significant number of breeding hen harriers; however, other native Upland breeding birds such as curlew and red grouse have suffered severe declines in recent decades and as such are of high conservation concern. Strict control of access and recreational activity on vulnerable soils should be implemented to reduce soil erosion and subsequent carbon loss. Curlew and hen harriers are recognised as an internationally important species, while (within the EU) upland heather moorland is designated as a priority habitat. In order to ensure protection and positive management of the Uplands, the following proposal is appropriate: Environment Proposal 6 Uses of the Uplands that contribute to the management and preservation of this distinctive environment will be supported. Dark Skies On the Isle of Man, 26 Dark Sky Discovery Sites have been identified, of which nine are located in the East. They are classified as Milky Way Sites meaning that at these sites the Milky Way is visible to the naked eye. The sites are accessible and light pollution is limited. The following Dark Sky Discovery Sites are located within the East: • Port Soderick Upper Car Park • Port Soderick Brooghs, Little Ness Car Park • Mount Murray Golf Club • Onchan Park • West Baldwin Reservoir Car Park • Clypse Kerrowdhoo Reservoi

Baffling and directionality of lighting must be sensitive to contain any necessary lighting within a subject site only. Watercourses and Wetlands The collection of hills in the East has produced a network of mountain streams which gradually join and widen to become the rivers flowing out into Douglas Bay, Port Groudle a
