RESIDENTS living next to Caterham's biggest building project for a decade have told of their construction "nightmare".
Mechanical diggers have moved into the former Oaklands healthcare site, to start on a multi-million pound, 161-home development.
And last week, large cranes began ripping down the three-storey office block on the Coulsdon Road plot.
But the cumulative effects of noise, dust and vibration has driven near-neighbours to distraction.
Leighton Copp, whose Soper Drive home is only about 20 metres from the Oaklands boundary wall, said: "My whole place has shaken when the demolition was at its height.
"Furniture and glass surfaces vibrated, and I've had a layer of dust all over my car and windows."
Mr Copp said he intends to apply to Tandridge District Council for a council tax rebate once the construction phase is over.
Next-door neighbour Kala Chotai said: "The noise has been terrible at times.
"It sounds like loud fireworks going off.
"Three massive diggers have been on the site just across the fence. My seven-year-old god-daughter comes to me twice a week, and I'm worried the dust may affect her asthma."
As well as the homes, the development will comprise a natural play trail, a woodland area, and a new £2 million health unit for people with autism and/or mental health needs.
The whole project should take about three years.
Developer Berkeley Homes has pledged £645,000 to create more places at nearby Hillcroft Primary School, Chaldon Road.
It has also offered to fund a pedestrian crossing in Chaldon Road, and has been invited to pay for a crossing in Rook Lane, Chaldon – at the request of Chaldon village councillor Pat Cannon.
Berkeley's senior site manager Ray Chaffey said operating hours – and any ensuing noise – are being limited.
He said: "Normal site hours will be from 8am to 6pm weekdays, and 8am to 1pm Saturdays.
"We will endeavour to keep Saturday working to a minimum.
"On-site parking will be available for all staff and sub-contractors, and wheel-washing facilities during the demolition and groundworks will minimise disruption to surrounding roads."
Matthew Biddle, the company's managing director, said: "We understand that people are always wary of change, but we believe the development of Oaklands will be a great asset to this area of Caterham.
"It will sit comfortably within the existing residential nature of the area, and provide much-needed homes for young professionals and families."
