A 'greedy' property developer who wants to build a 'soulless stack of boxes' that would overshadow his neighbours has been refused planning permission for the third time.
Businessman Mark Perkins wants to knock down an £825,000 chalet bungalow and replace it with a three-storey flat-roof home in exclusive Sandbanks - the UK's most expensive coastline in Poole, Dorset.
His plans have outraged his neighbours, Lesley and Robert Jefferies, who fear the development would completely overshadow their home, block their light and erode their privacy.
While the proposed mansion looks similar to neighbouring buildings, Mr Perkins' property happens to stand right up against the Jefferies chalet bungalow - sharing a wall and a driveway with it.
Mr Perkins' plans were turned down in February and July, but he tried again, paying for an 'overshadowing report' to prove the new house would not adversely affect the Jefferies' light.
A planning committee heard the overshadowing assessment confirmed the proposal did meet the minimum sunlight requirement, but this did not appease councillors, who unanimously voted against the plans.
Mrs Jefferies said the assessment was done on one sunny day and did not take into account varying weather conditions or the fact the sun does not rise and set in exactly the same spot through the year.
She said it would leave them 'hemmed in on all sides', and reduce light and privacy.

The 71-year-old, who has Parkinson's, said the only access to their home is a narrow driveway alongside Mr Perkins' property, and she needs 24-hour access.
The houses are currently attached by a wall and share a driveway and the plans include demolishing the front house and separating the new three-bed property from its neighbour.
When the Jefferies moved there four years ago, an elderly lady lived next door who had been there 30 years.
After she died, Mr Perkins, who lives 80 miles away in Ascot, Berkshire, bought the house.
They said Mr Perkins never consulted them over his plans and failed to explain how the two properties would be separated, but the latest plans included that he would 'make good' the side elevation of their home.
If built, the new house, which is in a private gated road yards from Sandbanks beach, would be worth over £2m.
Mrs Jefferies previously said: 'Out of area developers buy, build and move on with the intention of making a quick profit, with no regard for the impact they leave behind in their quest to make money and the devastating effect planning applications can have on the environment and living conditions of people.'
Despite planning officers recommending the development for approval, saying the proposed changes mitigated the impact on the Jefferies' property this time around, the councillors were still unimpressed.

Councillor Peter Sidaway said: 'It's subjective, but I don't think it's done enough to address the overbearing nature; I would find it hard to support this.'
Cllr Brian Hitchcock said: 'The problem is, what they should really do is buy the bungalow behind. Whatever gets built in front of it is going to be depressing for them.
'With scaffolding up they are not going to be able to get their car in and out down the side because it's quite narrow now and whatever they build there is going to be awful for them [the Jefferies].'
Cllr Marion Le Poidevin added: 'The people living there bought it as it was at the time. Should they be put to inconvenience and discomfort because somebody else wants to redevelop another property over which they have no control?'
They said despite the changes, the development was still overbearing and detrimental to the neighbours.
But the reprieve could be short-lived, as new planning rules come into effect at the end of the month, which means individual house applications will no longer be able to go to a planning committee, and officers will make the decision.
