The last house standing in Martin Place, Mortdale could soon make way for a four-storey unit block.
The modest, single-storey dwelling at 26 Martin Place is surrounded by older-style walk-up unit blocks.
It could soon be demolished and replaced by a "boutique small-scale in-fill apartment building" under a development application before Georges River Council.
With a 10.6-metre frontage, 360 square-metre block is described in the DA's Statement of Environmental Effects as an isolated parcel of land that is inconsistent with the area's R3 Medium Density zoning that permits residential flat buildings of up to 12-metres high.
If approved, the house will be replaced by a $1.68 million development with five units and undercroft parking for six cars.
Mortdale became popular in the 1920's providing housing for soliders who had returned from World War 1.
Historical development of the street over the past couple of decades has resulted in the residential land use being transformed to a higher densities comprising two- and four-storey blocks of units.
"The existing dwelling is not only inconsistent with the existing high density residential character along Martin Place, but it is also under-utilising the site's full zoning potential," the SEE states.
"The majority of the built form comprises older style walk-up flats of mixed ages and architectural styles.
"The subject site is the last remaining single storey residential dwelling (on the street) and being surrounded by flat buildings, the subject parcel can be identified as an isolated and constrained allotment.
"The proposed small-scale residential flat building has been designed to be an appropriate in-fill development that balances the development of a constrained site with the aim to provide a built form that is consistent and compatible with the existing higher density residential character.
"The development will positively contribute to the cohesiveness and visual appreciation of the streetscape," the SEE concluded.
