Bitter feud between neighbours sees residents claim they have received 21 years' worth of abusive letters about the state of their yard and where they park their car
- Couple in Perth suburb Hillarys claim they received abusive letters for 21 years
- Bizarre letters from 'a concerned resident' lecture about tidiness and car parking
- Another Hillarys homeowner got a letter demanding they add a second storey
Couple living in a beachside Australian suburb claim to have been sent anonymous letters from one of their neighbours for the past 21 years - addressing everything from mowing their lawn more often to where they should be parking their car.
The typed letters, delivered in a hand-written envelope and always signed 'a concerned resident' relentlessly lecture the couple.

Gary and Lindsay Thomson, who live at Hillarys north of Perth, claim to have received creepy anonymous letters for over 20 years lecturing them about the look of their home. Some of the letters are pictured

The 'concerned' local delivered the letter to the new arrival in the affluent waterside suburb of Hillarys on Perth's north coast (pictured)
'It goes on and on... we just want it to stop,' Mr Thomson told The West Australian.
The letters instruct the Thomsons to 'clean and tidy' their yard and to 'mow the lawn and weed the garden'.
Mr Thomson said he believed all the letters had come from the same person.
The sender had also complained to local authorities about how the Thomson's car was parked.
Recently the Thomsons were delivered a bill for mowing the lawns of a nearby rental property they had no connection to.

He said the 'concerned resident' arranged for a gardening contractor to mow a rental tenant's lawns and weed their garden.
The rental property manager was told the invoice for the gardening should be put in the Thomson's letterbox.
'I eventually explained to the agent that they were welcome to visit and see the numerous abusive anonymous letters and suggested the letter sender was the perpetrator of this criminal act.'
Mr Thomson said his wife was 'really struggling, really upset' and they could not understand why the 'concerned' neighbour doesn't just 'knock on my door'.
He is considering legal action but has not yet initiated any.
The Thomsons' frustrations were reported just days after another homeowner in the same suburb also received a bizarre anonymous letter that sounded as though it could have come from the same neighbour.
Their letter demanded they build a second storey to protect the exclusive reputation of the street.
The neighbour starts the letter by telling the homeowner they have witnessed a lot of change after living in the 'wonderful suburb' for 13 years.
'As you are probably aware nearly all surrounding homes are of a second story (tier) nature,' they explain.
'Your home, although presentable certainly does have a negative impact on the homes in the immediate perimeter.'

The resident added that they and other neighbours hoped the homeowner would add an extension to their one-storey dwelling for the good of the suburb.
'Myself and several other local residents are in the hope that you intend to alter the form of your home to keep track with immediate demographics.'
The cost of adding a basic second storey to a home can cost up to $380,000, according to construction company The Perfect Space.
The author finished their rant by explaining the renovation would benefit not only the homeowner but also their neighbours.
'Your future participation in such a thing would certainly keep home prices firm and and display a sense of professionalism in the area.'
The extraordinary letter was shared to the Bell Tower Times on Facebook on Monday, and was quickly inundated with comments.
Many encouraged the homeowner to antagonise the resident by adding old cars, tyres, shopping trolleys, an outside toilet or a caravan on their front lawn.
'Sounds to me like the surrounding neighbours want this home owner to stop mowing their front lawn and go buy a secondhand car wreck to put in their front garden. Let's see how THAT would affect house values', one user wrote.
