Why Perth downsizers are turning to Mos Lane as luxury apartment demand grows

Why Perth downsizers are turning to Mos Lane as luxury apartment demand grows

Perth's western suburbs have long been dominated by substantial family homes, but a growing number of homeowners are looking to make the move into apartments without sacrificing the space, quality or lifestyle they've become accustomed to.

It's a trend playing out at Mos Lane, ADC's boutique residential development on Manning Street in Mosman Park.

Now well under construction and more than halfway sold, the 66-residence development has attracted predominantly local owner-occupiers, many of whom are downsizing from larger homes in the surrounding suburbs.

In the latest Apartments.com.au Project Spotlight, House Agency Director Tom House discusses the changing demands of Perth's downsizer market, the importance of quality in getting buyers to make the move, and why premium apartment developments are increasingly finding favour with local purchasers.

"The majority of buyers have come from within one postcode," House says.

"It's a huge owner-occupier market, and people can see the quality that's gone into the project. They've really not cut any corners."

ADC has assembled a project team comprising architect Nelson + Koo, interior design practice Hecker Guthrie and builder Icon Construction.

The development comprises two buildings, Samson House and Manning House, with a mix of one, two, three and four-bedroom apartments, five street-fronting townhomes and two customisable penthouses.

Construction is progressing towards an anticipated completion in late 2027.

For House, one of the biggest challenges in selling apartments to established homeowners isn't necessarily convincing them of the location or the quality of the development. It's helping them understand how their lifestyle will translate from a large family home to an apartment.

"For someone who's lived in a two or three-storey house on the river for decades, downsizing isn't just about buying an apartment," he says.

"It's understanding how you right-size your life."

That thinking has influenced the design of Mos Lane, particularly the larger residences aimed at buyers accustomed to having multiple living areas, substantial storage and space to entertain.

Hecker Guthrie's interiors incorporate generous storage, detailed joinery, flexible multi-purpose rooms and large balconies. Selected residences also feature outdoor kitchens, while buyers can choose between light and dark interior schemes with natural stone and timber finishes.

The emphasis has been on creating apartments that can accommodate the way buyers already live, rather than requiring them to make significant compromises when leaving a larger home.

The same approach extends to the communal facilities.

Residents will have access to a private dining room with a caterer's kitchen, alfresco entertaining spaces and a bookable guest suite for visiting family and friends.

At ground level, Mos Lane Village will introduce a collection of retailers and everyday services, with plans for a boutique grocer, pharmacy, cafés and other conveniences.

For residents, it means many of the things they would ordinarily need to leave home for will be available within the development itself.

"People want to lock up and leave," House says.

"They still want all the luxuries of their house, just without the size and the maintenance."

House believes this shift in buyer expectations is becoming increasingly evident across Perth's apartment market.

While the city has traditionally been more heavily geared towards detached housing, established homeowners are showing a greater willingness to consider apartments where the design, location and amenity justify the move.

It's also influencing the type of developments being brought to market.

With construction costs remaining elevated, House says projects targeting buyers willing to pay a premium for quality are among those better positioned to proceed.

"I think we're seeing a real flight to quality," he says.

"People are looking for something that gives them everything they enjoy about their house, but in a more manageable format."

At Mos Lane, that demand has translated into more than half the residences selling, with prices having increased by around 15 per cent since the project launched.

The start of construction has also provided buyers with greater certainty around delivery, an important consideration for downsizers planning the sale of their existing home.

One-bedroom apartments have sold out, while remaining two-bedroom apartments are priced from $1.385 million and three-bedroom residences from $2.3 million.

The development's position between Cottesloe Beach and the Swan River is another drawcard, particularly for buyers who already live in the area and want to remain close to the neighbourhoods, schools and amenities they know.

Iona Presentation College and St Hilda's Anglican School are both nearby, while Mosman Park's established residential streets and proximity to the coast continue to underpin its appeal.

For House, the response to Mos Lane is indicative of a broader change in Perth's premium apartment market.

Buyers aren't necessarily looking for smaller homes. They're looking for homes that require less maintenance, without giving up the space, finishes and conveniences they've enjoyed for years.

It's a distinction that's increasingly shaping what developers need to deliver to attract Perth's next generation of apartment buyers.
