The Oswald apartments pitched as Mosman density-push continues
Twelve multimillion-dollar homes on one of Mosman's last large consolidated residential blocks are set to make way for The Oswald, a 103-apartment development that puts the suburb's Low and Mid-Rise Housing reforms to their most visible test yet.
The site at 42A-52 Rangers Avenue and 21-31 Brierley Street was assembled last year for a reported $86 million by entities linked to Arissa Group and its director Frank Scarf.
The consolidated 5,638 sqm block, bounded by Rangers Avenue to the north and Brierley Street to the south, with Cartreff Lane running along its eastern edge, gives the project an unusual three-street presence and a site footprint that is rare for the Lower North Shore.
DKO Architecture has designed a six and seven-storey building that steps across the sloping site in a U-shaped form, with the gap between the two arms of the building opening inward toward a central communal space that includes a pool and landscaped garden.
The form is explicitly drawn from the material language of the surrounding streets: a brick base articulated into finer-grain bays that roughly match the width of the bungalows being replaced, stepping up and down with the natural fall of the land rather than imposing a uniform datum.
Upper levels set back further from the street edge, keeping the building's presence lower and more domestic at the perimeter while the bulk consolidates toward the centre of the site.
The 103 apartments span a mix of 14 one-bedroom, 58 two-bedroom, 29 three-bedroom and two four-bedroom homes, spread across three basement levels that also accommodate 198 car spaces accessed from Cartreff Lane.
The site sits within easy walking distance of Cremorne town centre to the west, where the Spofforth Street strip offers cafes, grocers and everyday retail.
The Cremorne Point ferry wharf puts the CBD roughly 20 minutes away by water, with bus services along Military Road providing additional links across the Lower North Shore.
Mosman is going through a wave of new apartment projects, with the likes of Abadeen, WINIM, DARE, and Toohey Miller with apartment developments underway and in planning.
