More than 20 houses were this week under construction in Delroy Park Estate to meet the needs of a hungry market.

Civil works for further stages in the estate are turning former paddocks into land ready for dream homes. The process, repeated many times since the estate was established in 1997, has taken the developer's vision from paper to plains and built up the city's population across the bridge.

Selling agent Peter Whalan this week showed how Delroy Park had and was set to further change Dubbo's frontier.

He reported strong demand for the latest stages of the estate, sold as house and land packages.

About 120 blocks had sold in the section dubbed "the Outlook", located on the northern side of Minore Road, Mr Whalan said.

Five blocks within stage 11 commanding enviable views of Dubbo had sold for $230,000 and local builders and contractors were a presence this week.

"There are 20-odd homes under construction with a further 20 to start soon," Mr Whalan said.

Stormwater drains were going in for the first of three releases in stage 12, 50 per cent of which was already sold, the realtor reported.

Mr Whalan expected roadworks and other services would be completed by the end of February.

Demand had been consistent throughout his years as the selling agent.

"It still hasn't stopped and I think it will accelerate," he said.

There was a mix of buyers - some were upgrading from houses purchased in early stages of the estate, some were from other parts of Dubbo and others were from Sydney, Mr Whalan said.

"There are a lot of doctors, a couple of police and miners who work in Western Australia and are fly in, fly out," he said.

The launch of stage 13 is set for this month, with stages 14, 15 and 16 planned for the future.

Delroy Park has fitted a strategy of Dubbo City Council to balance the growth of the east.

Dubbo mayor Mathew Dickerson said the idea was to "really keep the CBD as the central point".

If all land zoned for residential use was developed immediately there would be more than 8000 blocks, of which 7900 were west of the Macquarie River, Cr Dickerson said.

"That's zoned land, it doesn't mean council expects it to be developed today but it is an indication of where council would like to see future development occur," he said.
