Belle Property Lake Macquarie's Katie Kepner has listed the custom-built, five-bedroom residence on over an acre of land at 8 Bombala Street, which she described as "one of Dudley's most inspiring houses".

"The appeal is the fact is it's an acre of pure coastal land," Ms Kepner said.

"Dudley is such a hidden gem for properties like this. If you want to be close to town but you also want the space, this is the best of both worlds. And they do not come up very often."

There is floor-to-ceiling glass and raked ceilings. The ground level is devoted to the kitchen, dining and a sunken, open plan living space complete with fireplace and bar.

There is also guest accommodation. Four bedrooms, a sitting room and the master suite are upstairs. The home has a choice of alfresco areas and an in-ground swimming pool.

Price guiding is in the mid-$3 million range and there were over 100 enquiries on the property in its first week of marketing.

It is set for auction on November 7 and open for inspection on Saturday at 11am.
