A rich pensioner is locked in a bizarre neighbours war with a cutting-edge architect and her partner, after erecting a huge wooden barricade that blocks off the windows and back door of their innovative £2 million house.Elspeth Pirie, 67, says she put up the hoarding behind her £3.6 million period property in an exclusive Kensington street to “protect her privacy” after “modernist” architect Luz Vargas and her artist partner William Milroy reconstructed their property and put in three new windows at the back.The elderly multi-milllionaire says she complained that her privacy was being invaded by the windows that overlooked her garden, and felt forced to put up the barricade when her protests were “ignored”.The outraged architect is now suing her, seeking damages and an injunction to compel Miss Pirie to take the barricade down, saying it prevents her and her partner from seeing out of their windows or using their back door.

They will be coming back to court.” “Had she been told of the proposal, she would undoubtedly have objected in the strongest terms regarding the lack of privacy the new windows would involve and the application would most likely have been refused,” the barrister adds.”In order to protect her position, Miss Pirie erected a hoarding to obstruct the current windows and registered a light obstruction notice,” he added.The barrister says that Miss Pirie also complains that “the works were incredibly prolonged and disruptive” and caused “chaos.””The garden was greatly damaged,” he claims, adding: “The permanent results of the works have been disastrous.”Miss Pirie also says the “rough and poor quality” rendered finish on the back of her neighbours’ property “detracts from her house.”Mr Bickford Smith, urging the court to reject the couple’s bid for damages and an injunction, says Miss Pirie had every right to protect her privacy and garden.”The current hoarding is not actionable… the complaint that the hoarding is too close to the wall should be rejected. Efforts to suggest some risk of rot or damp are tenuous,” claims the barrister.He adds that, if given notice that approved works need to be carried out, “Miss Pirie is ready to move the hoarding” but that “she is entitled to ensure that the removal is for legitimate purposes.”Of her counterclaim, the barrister says: “In the present case the claimants must have been intending to enhance the value of their house… valuation evidence suggests the enhancement was in fact in excess of £100,000.” The new basement was designed so that light filters down through a glass floor at ground level, via the glazed door and three new windows at the back of the Miss Vargas’ house.

And the fact that planning permission for new windows was not required meant that Miss Pirie never had the opportunity to object to them, he claims. The hoarding is starving them of light into their £100,000 new basement, the couple say, and also risks “rot and damp” developing in their home due to trapped moisture.Miss Pirie is fiercely defending her actions and counterclaiming for £50,000 she says she is owed because her neighbours’ builders carried out works to their house whilst standing in her garden.Her “falling out” with her neighbours dates back to 2010, when they obtained planning permission to reconstruct the back of their 200-year-old mews house in Holland Park and put in a new basement.Whilst both houses date from the Georgian era, the architect – whose aesthetic “values” are listed on her company website as “Modernists, timeless, innovative spatial experience” – had thoroughly up-to-date ideas for the redevelopment.
