Lock House, Lock, Lock Lane, Partridge Green, Horsham, RH13 8EG — Horsham District Council — Appeal Decisions Appeal Decisions APP/Z3825/W/25/3359623 & APP/Z3825/Y/25/3359626 4. Reference has been made to planning consent having been granted on an application under reference DC/25/0037. I have limited information on that permission although understand that it relates to conversion of Lock House into 3 dwellings and conversion of the garage block with flat into a dwelling. This proposal needs to be considered on its own merits but I will take that into account as necessary in coming to my decision. Main Issues 5. The main issue in both appeals is whether the proposed works would preserve the Grade II listed building known as Lock House or its setting or any features of special architectural and historic interest which it possesses. 6. An additional main issue on appeal A is the effect of the development on the Arun Valley Special Area of Conservation, Special Protection Area and Ramsar sites. Reasons Listed building 7. Lock House is a substantial country house dating from around 1900 near the settlement of Partridge Green. It is of a vernacular revival style constructed in red brick with a hipped tiled roof and a number of clustered brick chimneystacks over two storeys with rooms in the attic.

Lock House, Lock, Lock Lane, Partridge Green, Horsham, RH13 8EG — Horsham District Council — Appeal Decisions The house underwent significant reconstruction in around 1940 designed by Maple & Co., furniture designers. This included provision of high-quality interiors of that period that have largely been retained in the building. It was further altered and extended in the 1970’s when it began use as a convent before being converted back to a single dwellinghouse in the early 2000’s. The house is set within a large area of parkland with a number of outbuildings. 8. The significance of the listed building derives from its vernacular revival country house appearance in its parkland setting and internal finishes, particularly in relation to the parts of the house subject of reconstruction in around 1940. 9. The proposal would make minimal changes to the listed building. Whilst the internal finishes that are so important to its significance as a heritage asset are proposed to be retained, it would be subdivided such that the relationship between different parts of the building will alter. It would cease to be possible to move through the whole building, particularly between the original polite, family areas of the house and the areas provided for those who served them. This would affect the hierarchy of spaces within the building.

Lock House, Lock, Lock Lane, Partridge Green, Horsham, RH13 8EG — Horsham District Council — Appeal Decisions 10. Whilst that is the case, the proposals indicate limited physical change with the layout largely remaining. Provision of unit 1 would result in subdivision of what is currently a large family room. The upper floor would divide the existing space to provide bedrooms and bathrooms but this is already separate from the remainder of the building. Additional doors would open to the side of the building, breaking up the existing blank wall. This unit uses space added in the 1970s when the building became a convent and, as a result, these changes will not affect the understanding of the building as a country house. 11. It is understood that within unit 2, the wall between the proposed kitchen and dining room to be removed will reinstate the original relationship between the two rooms. As such, this will also not affect the understanding of the building as a country house. https://www.gov.uk/planning-inspectorate 2

A wall is proposed to divide the corridor between the main part of the house, which will become unit 2, and what is proposed to become unit 3 at ground floor level, with the staircase moved into the corridor behind. A doorway will be closed at first floor level. Although physically modest and original features can be retained, these changes would affect the links between different parts of the building, particularly the polite rooms that would be within unit 2 and the servants’ areas in what would become units 3-4. There would be other changes to the layout, including removal of the existing staircase, but these would be modest. Patio doors would replace windows in the proposed kitchen and living rooms on the ground floor, which would not materially affect the understanding of the building as a country house. Overall, the division to separate units 2 and 3 would affect the hierarchy between the polite and service areas of the country house. 13. Unit 4 would be a modest unit located to the rear of the house. At ground floor, the doorway linking to the remainder of the house would be closed.

Lock House, Lock, Lock Lane, Partridge Green, Horsham, RH13 8EG — Horsham District Council — Appeal Decisions The upper floor would be subdivided and the link to the rest of the house dating from 2003 would be closed. Overall, the changes to provide this unit would be modest and would have a limited effect on the relationship between the polite and service areas of the building. 14. Unit 5 would be formed out of the swimming pool extension that was built in 2007. Given its age and relationship to the remainder of the house, it would not affect the understanding of Lock House as a country house. 15. In addition, the subdivision of the garden would be likely to result in more residential paraphernalia relating to the individual new units. However, the manner in which the garden would be divided means that this only affects the parts closest to the house. The relationship to the wider parkland that serves the house would be retained. Nevertheless, division between the private areas and provision of individual paraphernalia for the different units would harm the understanding of the building as a country house to some extent. 16. The proposal includes the conversion of the existing garage block with flat to a single dwelling.

Lock House, Lock, Lock Lane, Partridge Green, Horsham, RH13 8EG — Horsham District Council — Appeal Decisions This is a modest building to the front of Lock House that previously contained garages at ground floor and a flat above. It is separated from Lock House with some mature planting that restricts views between the buildings and of the buildings together. It is currently being converted into a dwelling, I understand in accordance with planning permission reference DC/25/0037. Whilst its function as garages serving Lock House would be removed, the nature of its conversion means that it would remain subservient to the main house and retain elements of the existing appearance. For these reasons, its conversion would not affect the setting of Lock House as a large country house within a parkland setting. 17. For these reasons, I conclude that the subdivision of the house and immediate surrounds to provide five dwellings would affect the hierarchy of spaces within and immediately surrounding the building, such that it would harm features of special architectural and historic interest that the building possesses. However, conversion of the garage block would not affect the setting of the listed building.

Lock House, Lock, Lock Lane, Partridge Green, Horsham, RH13 8EG — Horsham District Council — Appeal Decisions The harm arising would be at the lower end of less than substantial harm to the significance of the building as a heritage asset. 18. The National Planning Policy Framework (NPPF) advises at Paragraph 212 that, when considering the impact of a proposed development on the significance of a designated heritage asset, great weight should be given to the asset’s conservation. https://www.gov.uk/planning-inspectorate 3

Lock House, Lock, Lock Lane, Partridge Green, Horsham, RH13 8EG — Horsham District Council — Appeal Decisions Appeal Decisions APP/Z3825/W/25/3359623 & APP/Z3825/Y/25/3359626 Significance can be harmed or lost through alteration or destruction of the heritage asset or development within its setting. As heritage assets are irreplaceable, any harm or loss should require clear and convincing justification. Accordingly, while less than the ‘substantial harm’ referred to in Paragraph 214 of the NPPF, the harm to the listed building is nevertheless a matter of considerable importance and weight. 19. Paragraph 215 of the NPPF establishes that, where a development proposal would lead to less than substantial harm to the significance of a designated heritage asset, this harm should be weighed against the public benefits of the proposal, including securing its optimum viable use. In this case, the building has been marketed as a single dwelling, which would be its optimum use given its significance as a country house. However, that has been unsuccessful. Given the extensive period of marketing, it is clear that use of the building as a single dwelling is not viable.

Lock House, Lock, Lock Lane, Partridge Green, Horsham, RH13 8EG — Horsham District Council — Appeal Decisions I note that the conversion to 3 dwellings under planning permission reference DC/25/0037 would also affect the relationship of the polite and service areas, perhaps to a lesser extent. Nevertheless and on balance, I consider that the proposed subdivision would result in the optimum viable use of the building. 20. In addition, the development would result in the creation of four additional dwellings. The Council indicate they are only able to provided 2.9 years supply of dwellings in comparison to the policy requirement in the NPPF to provide 5 years supply. The proposal would result in 5 additional dwellings or 2 taking account of planning permission reference DC/25/0037. Whilst the number of additional dwellings in this case is modest, this is, nevertheless, a public benefit of significant weight. 21. For these reasons, I conclude that the combination of securing the optimum viable use of the building along with the addition of houses toward meeting the need for housing in the area results in public benefits sufficient to outweigh the less than substantial harm I have found to the significance of the heritage asset. 22. Taking all the above into account, I conclude that the conversion of a single dwelling to 5no.

Lock House, Lock, Lock Lane, Partridge Green, Horsham, RH13 8EG — Horsham District Council — Appeal Decisions dwellings and conversion of the existing garage block with flat to single dwelling would comply with Policy 34 of the Horsham District Planning Framework (HDPF) and the NPPF. These seek to sustain and enhance the historic environment including securing the viable and sustainable future of heritage assets through preservation by uses that are consistent with the significance of the heritage asset. Arun Valley sites 23. Water supply to this site would be provided from the Sussex North Water Supply Zone (WSZ), an area of serious water stress. Water abstraction within the WSZ affects the water levels and flow in wetland habitats within the River Arun catchment area and downstream of the WSZ. These include the Arun Valley Special Area of Conservation (SAC), Special Protection Area (SPA) and Ramsar Sites (the Arun Valley sites). 24. The Arun Valley sites are a series of wetland meadows, alluvial grazing marsh and former raised peat bog, dissected by a network of ditches. The variation in soils and water supply lead to a wide range of ecological conditions and a rich and diverse flora and fauna.

Lock House, Lock, Lock Lane, Partridge Green, Horsham, RH13 8EG — Horsham District Council — Appeal Decisions The qualifying features of the protected areas that may be affected by development within the catchment area comprise wildfowl and waterbird assemblages, including Bewick’s swan, shoveler, teal and wigeon; wetland invertebrates, as well as a range of rare flora, including duckweed, water-cress, milfoils, dropworts and pondweeds. https://www.gov.uk/planning-inspectorate 4

The proposal would not be directly connected with or necessary to the management of the protected sites. Natural England suggest that additional development in the area is likely to affect the integrity of the Arun Valley sites. This effect would be through water abstraction to meet the needs of residents of development, including at the appeal site. That would lead to changes in water level and flow in the Arun Valley sites. It is necessary to consider any effects on a precautionary basis. The effects would arise from development either alone or in combination with other projects, such as other housing development in the area. 26. The appellant suggests that the development would be water neutral. This is based on their calculations that occupancy of the existing building and the proposed development would not lead to an increase in the amount of water used at the site based on their Water Neutrality Statement. The Council dispute the baseline is correct.

Lock House, Lock, Lock Lane, Partridge Green, Horsham, RH13 8EG — Horsham District Council — Appeal Decisions Nevertheless, they have suggested a condition has been used elsewhere that would allow further information to be provided to address this issue, including a water neutrality mitigation scheme and the purchase of credits through the Sussex North Offsetting Water Scheme (SNOWS) if it is not agreed that the development would be water neutral. 27. I note that Natural England withdrew its water neutrality position in Arun Valley during the course of the appeal. This relies on a package of resilience measures and proposed licence amendments to be implemented by March 2026. The Council suggest that, in these circumstances, there is not certainty that this will be resolved. From the evidence available, I agree that is the case and will proceed with the appeal on that basis. 28. The Council indicate that a condition requiring compliance with the Building Regulations Part G Optional Technical Standard would be required in order to restrict water use. This was not included in the list of conditions suggested by the Council. Such a condition would not be necessary as this would be adequately dealt with through the condition suggested by the Council relating to water neutrality. 29.

Lock House, Lock, Lock Lane, Partridge Green, Horsham, RH13 8EG — Horsham District Council — Appeal Decisions For these reasons and in accordance with the Conservation of Habitats and Species Regulations 2017 (as amended), as the competent authority it would be necessary for me to carry out an appropriate assessment to determine the extent of those effects, whether they could be avoided or whether mitigation measures could remove or reduce the effects. Appropriate assessment 30. The appropriate assessment needs to consider the effect of the development on the integrity of the Arun Valley sites and their qualifying features and species. In order to mitigate the effects of the development, it would be necessary to demonstrate water neutrality of the development, i.e. that the amount of water used by the development is the same or lower after the development has taken place as before. 31. The Council indicate that water neutrality can be addressed through the use of an appropriate condition in certain cases and have suggested such a condition in this case (condition 3). Natural England have confirmed they are content with that approach, subject to development being eligible to access the SNOWS. 32.

Lock House, Lock, Lock Lane, Partridge Green, Horsham, RH13 8EG — Horsham District Council — Appeal Decisions As the development is eligible to access the SNOWS and as this can be secured by condition, I conclude that there would be no adverse effect on the integrity of the Arun Valley sites. https://www.gov.uk/planning-inspectorate 5

Lock House, Lock, Lock Lane, Partridge Green, Horsham, RH13 8EG — Horsham District Council — Appeal Decisions As the development is eligible to access the SNOWS and as this can be secured by condition, I conclude that there would be no adverse effect on the integrity of the Arun Valley sites. https://www.gov.uk/planning-inspectorate 5

For the reasons set out in the appropriate assessment, I conclude that the development proposed would comply with Policy 31 of the HDPF, the draft Local Plan and the NPPF that require appropriate mitigation and compensation measures be provided to allow development where there would otherwise be direct or indirect adverse impacts on areas such as the Arun Valley sites. Conditions 34. To meet legislative requirements, conditions shall be imposed on both consents to address the period for commencement [condition 1]. I shall also impose conditions for the following reasons. In some cases, I have amended the wording of conditions suggested by the Council in the interests of clarity, taking account of Planning Practice Guidance. 35. A condition restricting new pipework being fixed to the external surfaces of the building is necessary to protect the special architectural and historic interest of the listed building, and its significance as a heritage asset [11]. Appeal A 36. I shall impose a condition specifying the relevant drawings as this provides certainty [2]. 37.

Lock House, Lock, Lock Lane, Partridge Green, Horsham, RH13 8EG — Horsham District Council — Appeal Decisions A condition requiring water neutrality is necessary to provide mitigation of likely significant effects on the Arun Valley sites [3]. A condition requiring a Biodiversity Enhancement strategy, along with a condition ensuring the development is undertaken in accordance with the Bat Building Inspection Report and restricting the provision of external lighting, are necessary to protect and enhance ecology in the area [4 & 9-10]. Details of landscaping works, their implementation and protection through a maintenance plan are necessary in order to ensure the development would reflect the landscape character of the area [5-6]. 38. Conditions requiring provision of a fast charge electric vehicle charging point and cycle parking are necessary to provide alternative travel to fossil fuel powered vehicles to contribute toward improved air quality and climate change [7-8]. 39. A condition requiring development to be undertaken in accordance with the Flood Emergency/Evacuation Plan to protect future occupiers from adverse effects from flooding [12]. 40.

Lock House, Lock, Lock Lane, Partridge Green, Horsham, RH13 8EG — Horsham District Council — Appeal Decisions I have not imposed a condition relating to parking as the Council suggest this is required to ensure provision of parking clear of highways and that the dwellings will be located some distance away from the closest highway. Information on parking layout is provided adequately through the landscape plan. I have not included conditions relating to making good and finishing the building works to match the existing and for new partitions to be scribed around existing ornamental mouldings as these would be satisfactorily covered in appeal B.

A condition restricting new pipework being fixed to the external surfaces of the building is not necessary as this would require separate listed building consent. Conclusions 44. I have not found any conflict with policies of the HDPF in relation to the conversion of Lock House to 5no. dwellings and conversion of the existing garage block with flat to a single dwelling. As a result, the proposal would comply with the development plan as a whole. I have not found any material considerations that indicate I should conclude other than in accordance with the development plan. 45. For the reasons given above the appeals should be allowed.
