REPORT OF HANDLING DELEGATED REPORT Ref No 25/01525/FLL Ward No P5- Strathtay Due Determination Date 12th January 2026 Draft Report Date 20th March 2026 Report Issued by JC Date 20th March 2026 PROPOSAL: Erection of dwellinghouse, garage/store, installation of air source heat pump and associated works LOCATION: Land 90 Metres West of Obney Croft (Garage Flat) Waterloo Bankfoot Perth PH1 4AS SUMMARY: This report recommends refusal of the application as the development is considered to be contrary to the relevant provisions of the Development Plan and there are no material considerations apparent which justify setting aside the Development Plan. BACKGROUND AND DESCRIPTION OF PROPOSAL The application site is in countryside to the south of Waterloo, on the north side of the U36 public road, west of Obney Croft. Planning permission is sought for a 1.5-storey, four-bedroom dwellinghouse, with detached garage/store, and an air source heat pump. The site is also within the River Tay SAC Catchment, an area of Class 3.2 Good Quality Agricultural Soils, and the Scottish Gas Networks Pipeline 1km buffer. However, the pipeline buffer is of limited relevance to this proposal, with SGN expected to be consulted for larger, major-scale proposals involving quarrying, demolition or power generation. SITE HISTORY Adjacent site to west 16/02035/FLL Erection of a dwellinghouse and garage with ancillary accommodation 30 January 2017 Refused 30 May 2017 Appeal Dismissed by Local Review Body Appeal Refusal Reason: “The proposal is contrary to Policy RD3 of the Perth and Kinross Local Development Plan 2014 and the Council’s Housing in the Countryside Guide 2012 as the proposal fails to satisfactorily comply with category (5) Conversion or Replacement of Redundant Non Domestic Buildings as the building is not of traditional form or construction, is not of architectural merit and does not make a positive contribution to the landscape or contribute to local character. It is also considered that the proposal cannot satisfy any of the remaining categories (1) Building Groups, (2) Infill Sites, (3) New Houses in the
Page 6
Open Countryside, (4) Renovation or Replacement of Houses, or (6) Rural Brownfield Land.” PRE-APPLICATION CONSULTATION Pre application Reference: None DEVELOPMENT PLAN The Development Plan for the area comprises National Planning Framework 4 (NPF4) and the Perth and Kinross Local Development Plan 2 (2019) (LDP2). National Planning Framework 4 The National Planning Framework 4 (NPF4) is the Scottish Government’s long-term spatial strategy with a comprehensive set of national planning policies. This strategy sets out how to improve people’s lives by making sustainable, liveable and productive spaces. NPF4 was adopted on 13 February 2023. NPF4 has an increased status over previous NPFs and comprises part of the statutory development plan. The Council’s assessment of this application has considered the following policies of NPF4: Policy 1: Tackling the Climate and Nature Crises Policy 2: Climate Change Mitigation and Adaptation Policy 3: Biodiversity Policy 4: Natural Places Policy 5: Soils Policy 9: Brownfield, Vacant and Derelict Land and Empty Buildings Policy 12: Zero Waste Policy 13 Sustainable Transport Policy 14: Design, Quality and Place Policy 16: Quality Homes Policy 17: Rural Homes Policy 18: Infrastructure First Policy 22: Flood Risk and Water Management Perth and Kinross Local Development Plan 2 – Adopted November 2019 The Local Development Plan 2 (LDP2) is the most recent statement of Council policy and is augmented by Supplementary Guidance. The principal policies are: Policy 1A: Placemaking Policy 1B: Placemaking Policy 5: Infrastructure Contributions Policy 6: Settlement Boundaries Policy 19: Housing in the Countryside Policy 41: Biodiversity

Planning Advice Notes The following Scottish Government Planning Advice Notes (PANs) and Guidance Documents are of relevance to the proposal: Creating Places 2013 Creating Places is the Scottish Government’s policy statement on architecture and place. It sets out the comprehensive value good design can deliver. It notes that successful places can unlock opportunities, build vibrant communities and contribute to a flourishing economy and set out actions that can achieve positive changes in our places. Designing Streets 2010 Designing Streets is the policy statement in Scotland for street design and changes the emphasis of guidance on street design towards place-making and away from a system

APPRAISAL Sections 25 and 37 (2) of the Town and Country Planning (Scotland) Act 1997 require that planning decisions be made in accordance with the development plan unless material considerations indicate otherwise. The Development Plan comprises NPF4 and the Perth and Kinross Local Development Plan 2019. The relevant policy considerations are outlined in the policy section above and are considered in more detail below. In terms of other material considerations, involving considerations of the Council’s other approved policies and supplementary guidance, these are discussed below only where relevant. The determining issues in this case are whether; the proposal complies with development plan policy; or if there are any other material considerations which justify a departure from policy. Policy Appraisal Policy 6 - Settlement Boundaries of the Perth and Kinross Local Development Plan 2019 (LDP2) specifies that development will not be permitted, except within the defined settlement boundaries set out in the Plan. Notwithstanding this, LDP2 Policy 19: Housing in the Countryside acknowledges that opportunities do exist for housing in rural areas to support the viability of communities, meet development needs in appropriate locations whilst safeguarding the character of the countryside as well as ensuring that a high standard of siting and design is achieved. Supplementary Guidance associated with LDP2 Policy 19 is supportive of dwellinghouses which add to a rural building group within a definable adjacent site provided that the following can be demonstrated: • new housing will respect the character, scale and form of the existing group, and will be integrated into the existing layout and building pattern; • new housing will not detract from the visual amenity of the group when viewed from the wider landscape; and • a high standard of residential amenity will be provided for both existing and new housing. The Supplementary Guidance makes clear that a building group is defined as 3 or more existing buildings of a size at least equivalent to a traditional cottage and which, when viewed within their landscape setting, appear as a group. The majority of the buildings in the group should either be residential or be suitable for conversion to residential under Category 5 of the guidance. Premises which are smaller than a traditional cottage, such as small domestic garages and outbuildings, will not count towards the requirement for at least 3 buildings. In addition, is supportive of the development of up to 2 houses in gaps between established houses, or a house and another substantial building at least equivalent in size to a traditional cottage, may be acceptable where: • The plot or plots created are comparable in size to the neighbouring plots and have a similar size of road frontage;
Page 10
• The proportion of each plot occupied by the infill house or houses is no greater than that of the neighbouring plots; • The are no uses in the vicinity which would prevent the achievement of an adequate standard of amenity for the infill house or houses, and the amenity of any existing neighbouring house is maintained. • The size and design of the infill house or houses is sympathetic to the neighbouring buildings. • The full extent of the gap is included within the infill plot or plots – for the avoidance of doubt, the retention of a field access within the infill plot or plots will not be permitted. NPF4 Policy 17: Rural Homes does not directly refer to rural building groups or infill sites, however Policy 9(b): Brownfield, Vacant and Derelict Land and Empty Buildings does offer some support for proposals on greenfield sites where explicitly supported by policies in the LDP. Separate to this, Policy 17(a) sets out several categories of development which it is supportive of “where the development is suitably scaled, sited and designed to be in keeping with the character of the area…” The current proposal does not meet any of these categories as it is (i) not within an allocated site, (ii) not brownfield land, (iii) not a redundant or unused building, (iv) not reuse of historic asset, (v) not worker accommodation for which an essential need has been demonstrated, (vi) not a retirement home, (vii) not subdivision of a house and (viii) does not reinstate a former dwelling one for one. Part (b) of Policy 17 is a general follow-on of this, and categories (c) and (d) of NPF4 Policy 17 are not relevant to this application site. In this instance, the application site comprises a grassed paddock enclosed by a beech hedge which has existed for some time along its southern road boundary, but appears from aerial imagery to have been introduced more since approximately 2021 along its west and north boundaries. The Supplementary Guidance states under Category 1 that “Fencing or young trees or hedging planted with the specific intention of creating a site will not be accepted as existing landscape features for the purposes of this Supplementary Guidance.” To the east are the grounds of Obney Croft, where a dwellinghouse is currently under construction following planning permission in June 2018 (18/00684/FLL), along with a detached garage with ancillary accommodation which appears to have been built first as part of that permission. That new dwellinghouse followed the demolition of an unfinished, structurally unsound dwellinghouse which benefited from a 2001 consent (01/00884/MOD). An agricultural shed is located at the north-west of that site, and was consented in 2003 (03/00588/PN). There is a gap of approximately 35 metres between the dwellinghouse being constructed and the boundary with this application site, and the agricultural shed is set back a similar distance from the road boundary. This clear gap undermines the claim that this can be considered an infill site, as Category 2 of the Housing in the Countryside Supplementary Guidance includes the requirement that “The full extent of the gap is included within the infill plot or plots”. The land to the east of the application site contains two shipping containers along the roadside boundary, and a diagonal track which leads to an agricultural shed with T- shaped footprint which appears to have been consented in 2006 (06/01145/PN), and extended to the west around 2018, for which no planning history is available. This shed is set back a similar distance (approximately 34 metres) from the public road as the agricultural building at Obney Croft, which is approximately 83 metres away, and therefore itself lacks road frontage for the purposes of considering an infill site. One of
Page 11
the requirements of the Supplementary Guidance is that “The plot or plots created… have a similar size of road frontage”, and it would also be inappropriate to consider the two roadside shipping containers as forming a road frontage to justify an infill development. In general, the built form is too dispersed for this application site to be considered an infill site or an extension to a building group. Indeed, Category 1 of Supplementary Guidance states that “The majority of the buildings in the group should be either residential or be suitable for conversion to residential under Category 5 of this guidance.” In this instance, half (two of four) of the buildings are non-residential and are not traditional buildings suitable for conversion under Category 5 of the Guidance – a fact that is emphasised by the 2017 refusal and appeal dismissal of a proposal to convert the western agricultural building to residential use (ref: 16/02035/FLL). The remaining buildings, including the under-construction dwellinghouse and its detached garage/ancillary accommodation, are located at the eastern end of the building pattern and much closer to the road (set back 9 and 16 metres respectively). This is in stark comparison to the 34-35 metre distance of both agricultural sheds from the road. Other smaller entities such as the shipping containers are not considered substantial buildings for the purposes of policy as set out earlier in this section. To summarise the analysis of the principle of this proposal, it is recognised that by looking at recent aerial imagery, one could make the argument, however superficially, that the current proposal may occupy a clearly defined site in the countryside. However, a more detailed analysis shows that the hedging which encloses the north and west of the site has only been introduced in the past five years. In addition, the established building pattern is dispersed and not majority residential in nature, with the two agricultural sheds either side of this site being considerably set back from the public road and not suitable for conversion to residential. There is a gap outwith the applicant’s control of approximately 35 metres between the rear of the Obney Croft dwellinghouse and the east boundary of this application site, and to the west the application site is flanked by roadside shipping containers which cannot be considered a building or a plot with a meaningful road frontage for the purposes of residential infill development. The application site is therefore a contrived attempt to create a definable residential plot, but ultimately fails to constitute an infill site or an extension to a building group. The proposal therefore fails to accord with NPF4 Policy 17: Rural Homes and LDP2 Policy 19: Housing in the Countryside, and consequentially is contrary to NPF4 Policy 16(f)(iii): Quality Homes, which requires consistency with policy on rural homes. NPF4 Policy 9: Brownfield, vacant and derelict land and empty buildings must also be considered. This site is not considered brownfield. This policy also states that the development of greenfield sites will not be supported unless: • allocated for development – this site is not within the settlement boundary; or • the proposal is explicitly supported by policies in the LDP – This site fails to accord with LDP2 Policy 19: Housing in the Countryside as set out earlier in this section. The principle of developing the site for a single dwellinghouse is therefore not acceptable in this instance.
Page 12
Design and Layout, Visual Amenity, Landscape The proposal is for a 1.5-storey dwellinghouse with double-pitched roof and T-shaped footprint, fronting the public road. The proposed triple garage structure would also have a double-pitched roof and be oriented similarly towards the road. The size and scale of the proposed house, whilst occupying a large portion of the site, is considered acceptable in this instance, and the garden ground would benefit from the enclosure of the existing beech hedging. Further information regarding the appearance of the proposed timber or composite cladding would have been sought from the applicant had the principle of development been considered acceptable. In addition, appropriate landscaping proposals would also have been sought by planning condition to secure compliance with NPF4 Policy 14: Design, Quality and Place, and LDP2 Placemaking Policies 1A and 1B. Notwithstanding the above analysis, the design of the proposed house would not overcome the conflict with Development Plan policy as set out earlier in this report. Residential Amenity The proposal contains an air source heat pump (ASHP) at the north-east elevation of the property, and supporting information has set out some information as regards the make and model. The Environmental Health Team consider that given the distance to neighbouring properties, the noise levels may be acceptable subject to standard noise rating informative being placed on a decision in the event of approval. There are no overshadowing or overlooking concerns associated with the proposal, due to its distance from the nearest residence at Obney Croft to the east. Therefore, the proposal is acceptable from a residential amenity point of view. Roads and Access The site is proposed to be accessed from the existing track which links the U36 public road to the existing agricultural building to the west of the application plot. The parking provision within the site is in accordance with the National Roads Development Guide, and there is also sufficient turning and manoeuvring space for vehicles. A septic tank has been proposed, and in the event of approval, an informative would have set out the expectations for desludging vehicle access in respect of that waste water treatment system. This element of the proposal accords with NPF4 Policy 13 and LDP2 Policy 60B. Drainage and Flooding As set out in the Roads and Access section, a private septic tank has been proposed and would require to be serviced appropriately. The site is not subject to flood risk, but limited details have been provided in respect of surface water drainage within the site. If approval had been recommended, a planning condition would have secured additional drainage details to ensure compliance with NPF4 Policy 22 and LDP2 Policy 53B, 53C, and 53E.
Page 13
Contaminated Land The Contaminated Land Team have not raised any adverse comments in respect of the proposal, but have advised that it shall be the responsibility of the applicant to satisfy themselves that the ground conditions are suitable for the proposal, were it to be approved. This element of the proposal accords with NPF4 Policy 9(c) and LDP2 Policy 58A. Conservation Considerations There are no conservation concerns associated with this proposal. Natural Heritage and Biodiversity No information has been submitted in respect of natural heritage or biodiversity. Had the application been recommended for approval, a planning condition would have required a landscaping plan and biodiversity enhancement in the form of two bird nesting boxes and two bat boxes, to ensure compliance with NPF4 Policy 3: Biodiversity and LDP2 Policy 41: Biodiversity. The site lies within an area of Class 3.2 Good Quality Agricultural Soils. The proposed plot is modest in size, and has been isolated from the nearby agricultural land by the construction of buildings, installation of shipping containers, access tracks and hardstanding. However, this does not outweigh the in-principle conflict with Development Plan policy as set out earlier in this report. Developer Contributions The Developer Contributions Guidance is not applicable to this application and therefore no contributions are required in this instance. Economic Impact The economic impact of the proposal is likely to be minimal and limited to the construction phase of the development. VARIATION OF APPLICATION UNDER SECTION 32A This application was varied prior to determination, in accordance with the terms of section 32A of the Town and Country Planning (Scotland) Act 1997, as amended. The variations incorporate changes to the submitted drawings in the interest of accuracy. PLANNING OBLIGATIONS AND LEGAL AGREEMENTS None required. DIRECTION BY SCOTTISH MINISTERS None applicable to this proposal.
Page 14
CONCLUSION AND REASONS FOR DECISION To conclude, the application must be determined in accordance with the Development Plan unless material considerations indicate otherwise. In this respect, the proposal is considered to be contrary to the Development Plan. Account has been taken of the relevant material considerations and none has been found that would justify overriding the Development Plan. Accordingly, the proposal is refused on the grounds identified below. Conditions and Reasons 1 The proposed dwellinghouse is unacceptable in principle as it is not considered a rural infill site or appropriate extension to a rural building group. The proposal therefore fails to accord with NPF4 Policy 17: Rural Homes and LDP2 Policy 19: Housing in the Countryside, and consequentially is contrary to NPF4 Policy 16(f)(iii): Quality Homes. Justification The proposal is not in accordance with the Development Plan and there are no material reasons which justify departing from the Development Plan. Informatives None Procedural Notes Not Applicable. PLANS AND DOCUMENTS RELATING TO THIS DECISION 03 04 05 06 07

aroTHERM plus: air source heat pump Heating Hot water Renewables
Page 24
What is an air source heat pump? Air source heat pumps extract thermal energy (heat) from the outside air and convert this into heating and hot water for your home. They are designed to work in cold temperatures and are suitable for a range of homes, from a small apartment* to a large detached property. The heat pump needs to be located outside the property: it’s very quiet in operation, being no louder than a domestic fridge. Air source heat pumps do require electricity to operate, and approximately 75% of the energy required is generated from the outside air, with only 25% being required from electricity. This means that 75% of the energy you use will be from a renewable source, which will reduce your emissions and CO2 impact. *Air source heat pumps need to be located outside. They must be installed on a solid base or structurally secure wall. A qualified and reputable renewables installer will be able to advise you if your home is suitable for an air source heat pump. Air source heat pump Best suited for: New build, renovations and replacement What are the advantages? • Higher hot water demand capability High flow temperatures • Sustainable Reduce your carbon footprint with a GWP of just three • Eligible for government incentives Such as BUS • Energy efficient With the highest ErP rating save money on your fuel bill* • Designed for a peaceful home With noise levels as low as 54 dB(A) • App controlled When installed with VR 900 or sensoNET control *When compared to replacing an oil system Two plus bathroomsOne or more people+++ Page 3Page 2

Key terms explained What is sound power? GWP is a comparative value that indicates the greenhouse effect of a greenhouse gas, such as a refrigerant, if it were to be released into the environment. The higher the value, the worse the impact on the climate. The aroTHERM plus has a very low impact on the environment, with an outstanding GWP of just three. Coefficients Of Performance (CoP) CoP is the efficiency ratio of heating output compared to the energy input required to power the unit depending on the air and flow temperatures. The higher the CoP figure, the more efficient the heat pump is. Air source heat pump units usually have a CoP of around 3 - 4, the aroTHERM plus has a CoP up to 5.2, making it highly efficient. Seasonal Coefficient Of Performance (SCoP) SCoP is a value that describes the efficiency of the output of the heat pump. It’s derived from analysing the data from a combination of tests taken over the course of a year (to allow for seasonal variation). A SCoP value is used to calculate the running cost of your heat pump; the higher the SCoP value, the more efficient the heat pump and the lower the running costs of your heating system. What is Boiler Upgrade Scheme (BUS)? The Boiler Upgrade Scheme (BUS) provides upfront grants to support the installation of heat pumps in homes in England and Wales. All Vaillant heat pumps are MCS accredited and eligible for BUS. Sound power This is the rate at which sound energy is emitted from a unit. The sound power of all heating products like heat pumps and boilers are displayed on the ErP product label. Sound pressure This is the volume of sound you hear as the sound travels through the air. So the further away you move from the sound source, the lower the lower the volume of sound you hear. Sound pressure values are always lower than sound power values. An example of the sound pressure value would be 46dB(A) the (A) shows that is a sound pressure value.
