A property tycoon is locked in a bitter planning battle with council officials over his bid to transform the grand former home of W.S. Gilbert into a sprawling family mega-mansion.
Private equity boss James Woolf bought the grand 1880 residence - built for the famed Gilbert and Sullivan dramatist - for £7.1million in 2023, hoping to bring the historic property into the 21st century.
But the vast 12,000 sq ft house in affluent South Kensington - long seen as one of London's architectural treasures - has stood empty ever since as a long-running row with planners drags on.
Mr Woolf wanted to install a lift, create a basement bar and wine cellar among plans to reconfigure the imposing property for his 'multigenerational family' as part of an ambitious £6million renovation that would see the property fully restored.
However, Kensington and Chelsea Council has repeatedly knocked back the plans, arguing the changes would damage the heritage of Gilbert's grade-II listed former home.
The father-of-five, whose company specialises in high-end restorations of historic buildings, including in Italy and the Czech Republic, said he had been met with a 'computer says no' attitude by officials over plans for the Flemish-style property.
Mr Woolf said he had subsequently been left 'in limbo', with his family still no closer to knowing when they might be able to move in.
He said: 'I'm in property - the buildings that I own are some of the oldest in the Czech Republic. The oldest one dates back to the 15th century.

'We own a castle in Tuscany that dates back to the 10th century. It is the oldest castle and the highest in Chianti - Michaelangelo visited there.
'So I would like to think I know a thing or two about heritage and preserving it.
'When I go to the heritage people in Czech, we have a discussion. When I go to them in Florence, in Italy, we have a discussion.
'My experience of them is that they get it - they want the buildings to work, not to sit there unused as relics.
'Then you come to Chelsea and it's just a joke.
'They don't negotiate, they don't compromise and they are completely intransigent.
'What we are trying to do is not a lot - but it is computer says no, every time.
'They simply don't want me and my family moving into a 12,000-foot home. It's perfectly obvious.
'They don't care. They don't care about the building.'
The Grade II-listed property had most recently been used as corporate offices before Mr Woolf bought it, with hopes of restoring it to family use.
His plans included reworking the upper floors to create a new master bedroom, adding en-suite bathrooms and introducing underfloor heating and air conditioning.
But the bid to drag the Victorian house into the modern age was rejected after council officials and planning inspectors ruled the works would harm its historic character.

Kensington and Chelsea Council said the scheme would harm the 'historic interest' of the building.
Gilbert lived at the property until 1889, having reportedly built it with profits from Patience, the 1881 comic opera he created with Arthur Sullivan.
It was there that he completed the libretti for The Mikado, The Yeomen of the Guard and The Gondoliers.
The house even impressed Beatrix Potter, who described it as 'a very handsome house indeed'.
WHO WAS W.S GILBERT?
William Schwenck Gilbert was a renowned dramatist, librettist and poet during the Victorian era best known for master-minding operas such as The Mikado.
Seven theatres in London opened with Gilbert's plays, the most famous of which include Pinafore, The Ratepayers' lolanthe and Di Yam Gazlomin.
Gilbert was knighted by Edward VII in 1907 for his work as a dramatist.
He died aged 74 in 1911 after drowning while trying to rescue a young swimmer in a lake on his Harrow estate.
Much of that splendour remains, including Gilbert's quirky quotations stencilled above doorways and his initials worked into features such as an ornate chimney piece in the entrance hall.
Mr Woolf insisted his plans were modest and designed to bring the property back into proper residential use.
But he accused officials of being 'aggressive, obtuse, dismissive' and refusing to compromise.
He said: 'The most important thing for this building, the most, is to restore it back to its original use as a home. The listing is because of the unique facade and other elements, not because of the basement layout.
'But they are bureaucrats and they do not care about the building.
'The long and short of it is there is now 12,000 feet of residential space not being used in London.
'I would move out of my house, which would free up my house because I would rent it. And then other people would move along the chain.
'But we are at a complete standstill. No work is taking place, there is no moving-in date, and the building is effectively frozen.
'The only person at the house is one security guard.'
Mr Woolf - whose company FlowEast describes itself as one of the biggest British private investors in the Czech Republic - took his fight to the independent Planning Inspectorate after being refused permission for internal and external alterations.
There, he argued that 'significant enhancements' were needed to turn the house into a home fit for his family while also carrying out essential restoration work.
Agents acting on his behalf said 'large houses of this type demanded a lift' and argued that without one the property would be difficult to sell.
They also said wealthy buyers in South Kensington had come to expect open-plan living and en-suite bathrooms.
But planning inspector Fiona Cullen ruled the changes would carve into the building's historic layout and erode its original character.

She said the open-plan basement design, with bar, seating and lounge areas, would cause a 'considerable loss of historic fabric' and a 'marked erosion' of the basement's historic layout.
Ms Cullen accepted the proposals would bring some heritage benefits, including repairs to original wallpaper and damaged floorboards, but said these were 'tempered by the scale of the proposal'.
She ruled parts of the scheme would 'fundamentally disrupt the historic architectural, social and functional hierarchy of the floors within the building'.
In an earlier appeal decision in December, the proposed lift was also found not to be 'a fundamental necessity'.
Plans to install an air-conditioning unit on the roof were thrown out last year.
Mr Woolf's agents insisted the scheme was aimed at improving living standards, boosting energy efficiency and securing the building's long-term future as a single-family home.
They said: 'The overall aim of the proposal is to make minor modifications and upgrades within the property so that it can effectively be utilised as a modern household and enjoyed by a multigenerational family.'
But the Planning Inspectorate concluded: 'I recognise the desire of the appellant to adapt the building to 'suit their needs'… however, heritage assets are required to be conserved in a manner appropriate to their significance.
'I conclude that the proposal would fail to preserve the special architectural and historic interest of the Grade II listed building.'
Subsequent applications have been approved in piecemeal form, while others have been refused and are now being appealed.
Mr Woolf said the planning dispute had put him off investing in other properties in the UK.
'This experience that I've had, there is zero chance I would buy a building with any form of listing in the UK again,' he added.
'People often rely on cliches like 'Kafkaesque bureaucracy' when discussing the Czech Republic or 'systemic inefficiency' in Italy.
'However, in my experience operating across all three markets, the Royal Borough of Kensington and Chelsea stands alone.
'What I have endured here is the most disingenuous approach to property planning I have ever encountered - a masterclass in administrative bad faith that makes Continental red tape look like a model of transparency.
'It is hard to see how anyone could be encouraged to take on heritage projects in this country. You'd have to be mad.
'There is no hope for the UK to generate the residential space the country needs.'
A Kensington and Chelsea spokesperson said: 'We recognise that unsuccessful appeals to the Planning Inspectorate can be disappointing. Our officers assess every proposal fairly and consistently against the relevant legislation and planning policies, balancing the need for buildings to remain usable with the duty to preserve their special architectural and historic interest.
'The property at Harrington Gardens is a nationally important Grade II* listed building and any decisions taken have been explained and justified against policy, with the applicant having the right to appeal to the Planning Inspectorate.
'We offer a full pre-application advice service and would welcome a discussion with the applicant on how best to move forward and respond to concerns raised by both the Planning Inspectorate and the local planning authority.'
