Gowrie NSW, the new owner of the former Newstead Bowling Club, has lodged a development application to Orange City Council to convert the Hill Street building.

It said the conversion would not affect the heritage look of the exterior of the Victorian style building which was constructed in the 1890s.

"The existing Newstead mansion would be retained. The proposal would have no impact on the presentation of the site to Hill Street," the DA states.

"Almost all the fabric to be removed constitutes later additions to the place [which] are of no significance. Only minor interventions are proposed to the original fabric."

The DA said the gardens would also not be largely affected.

"All mature landscaping within the front setback would be retained and new appropriate landscaping would be implemented."

The DA states the child care centre would have up to 92 places for children aged 0-5 years.

It said it would employ up to 21 staff and operate from 6.30am-6.30pm Monday to Friday. It would not be open on weekends.

The DA states it is expected noise levels in the area would rise when the children played outside.

However, it said the impact on neighbours could be reduced by building a 1.8 metre high fence.

The project will also require 23 car parking spaces under planning rules.

The DA states there are 20 spaces available along with on-street parking capacity.

It said Newstead was built for solicitor De Vries Pilcher and wife Emily about 130 years ago.

A heritage report in the DA said Mrs Pilcher died at Newstead in 1923.

It became the Newstead Bowling Club in 1955 when additions were made to the building.

The DA states much of the additions would be removed as part of the construction work.

"The scope of the work [includes] removal of unsympathetic loading area and laundry extensions (circa 1955) located on the southern side of the Newstead building and construction of a new accessible entry to the child care facility," it said. The DA will be on public exhibition.
