Former Spice Girl Geri Halliwell-Horner has irked her neighbours with some lavish plans for her Grade II-listed mansion in Oxfordshire. She has aims to install a huge 77ft horse walker, which is reportedly costing her a whopping £30,000.

The 52-year-old and her F1 boss husband, Christian Horner, own a horse racing company called OMBI and have built new stables for 14 horses - all named after Geri's solo career hits - on land adjacent to their main home. The new space will provide enough room to exercise eight horses at a time.

In a statement on behalf of Geri and Christian, a planning agent explained the plans, writing: "The work consists of installing an 8-horse horse walker which will be constructed from a steel frame with black composite panels forming the roof and low wall cladding.

"Polygonal in shape, it will measure approximately 22m in diameter, 3m to the eaves and 7m to the central peak. This form means that this lightweight structure will be largely screened from all angles once the existing new hedging matures."

It continued: "The proposed horse walker will provide the horses with a space to be suitably exercised off the tether. The form, lightweight structure, materials and position of the walker means it will be a very discreet addition to the landscape and is closely associated with the existing stud barn. Once the new hedgerow the matures it will be largely screened from all public and private views onto the farm."

However, the couple's plans for home improvements have angered neighbours, who have complained to the local council that the huge structure would obscure their view of "mature trees".

Commenting on the latest plans, one neighbour reportedly said: "Whilst we do not object to the principle of a horse walker to support the private equestrian use of the adjacent equestrian barn and other equestrian activities, we object to the plans as currently presented."

The neighbour added: "The proposed structure would be extremely visible from our property, other village properties, and from a public highway. Additionally, the proposed structure sits on the top of a ridge rising up from a stream and thus would be extremely prominent on the skyline, obscuring mature trees from view."

A decision will be made on the new application at a later date.
