Have to question the appropriateness of a garage door ("enclose existing carport") at the front of this property which is within a heritage conservation area.
Garages and garage doors were not typical of the times within the period in which the heritage housing in this area of North Sydney were constructed. Even though last century around 3 properties, within the area of this conservation order (Lavender, Walker and Arthur Streets), used or built car storage facilities at the front of their properties, I do not think it appropriate to further degrade the heritage nature of conservation area with the change at the front of the subject property. Particularly as the subject property already has off street parking facilities in the laneway at the rear.
Other residents have used the rear of their properties for carparking. To now permit the erection of further non heritage items in this area will simply degrade, not only this current conservation area, but all conservation areas in the NSC area.
