Geri and Christian Horner have won their planning battle after building an outdoor pizza oven, gazebo and pergola without permission at their £9.2million Grade II Oxfordshire mansion. The couple had been met with objections from neighbours and heritage experts who claimed they were ruining the ‘tranquillity’ of the quaint village with their never-ending home improvements. But permission for the gazebo and pizza oven was granted retrospectively by planning officers on Monday, after the height of the gazebo and pizza oven flue were reduced. The report deemed the structures wouldn’t harm the ‘living conditions’ of neighbouring properties. The Sun reports the council wrote: ‘Giving regard to their proposed use and design, there is no potential for overlooking or views to neighbouring properties.’Whilst both structures would result in outdoor residential activity, the scale and domestic nature of the use would not generate levels of noise or activity that would harm the living conditions of neighbouring occupiers. Geri and Christian Horner have won their planning battle after building an outdoor pizza oven and pergola without permission at their £9.2million Grade II Oxfordshire mansion The couple had been met with objections from neighbours who claimed they were ruining the ‘tranquillity’ of the quaint village with their never-ending home improvements’The development would therefore maintain an acceptable level of privacy, daylight and outlook for surrounding residents.’Overall, it is considered that the proposal would not give rise to any unacceptable impacts on neighbouring residential amenity.’An initial application for the oak framed gazebo, pizza oven and pergola was refused last year after several neighbours submitted objections. ‘This has already been built, along with a sauna block higher than the wall, which in a conservation area is unacceptable,’ one wrote.Another neighbour wrote: ‘The council would have been onsite to know this construction has been built for at least four months when signing off a swimming pool and other construction.’Questions need to be asked and answered. Somehow, a 30 foot long pergola was missed.’Another neighbour questioned why action hadn’t been taken sooner to stop the development.The couple re-applied for planning permission for just the pergola in the middle of January and it was granted in March. Permission for the pergola and pizza oven was granted retrospectively by planning officers on Monday, after the height of the gazebo and pizza oven flue were reduced The saga is the latest in a long-running planning row with their neighbours. In March they were finally granted permission to build a £30,000 horse walker That same month they also resubmitted a second application to validate their oak framed gazebo with lead roof and a brick-built pizza oven, after reducing the height of both by 300 metres.They admitted building work on the gazebo started on 14 April last year but it hadn’t been completed.The saga is the latest in a long-running planning row with their neighbours after buying the property in 2006.In March they were finally granted permission to build a £30,000 horse walker. The couple own a horse racing company called OMBI and have built new stables for 14 horses.Locals near their home objected to the works over concerns relating to its height and the visual impact on the area.Despite them committing to plant 12 new trees to hide the structure, several objections were formally lodged with West Northamptonshire District Council.However, council officials have granted Geri and Christian permission to build the walker, subject to strict conditions.In its report, the council said: ‘The building shall be used for private equestrian and land management uses only and no commercial use, including riding lessons, tuition, livery or competitions shall take place at any time.’Whilst it is acknowledged that the walker incorporates a steep pitched roof for its size, the general design is functional in form.’Giving regard to its siting, scale and rural-equestrian character, the design is considered appropriate for the open countryside location and would not harm the character of the area.’A local who objected to the works, told The Sun: ‘Whilst we do not object to the principle of a horse walker… we object to the plans as currently presented.’The proposed structure would be extremely visible from our property, other village properties, and from a public highway.’In a rural conservation area this would be unacceptable as it would completely change the character of the area.’ The Daily Mail has contacted their representatives for comment.
