Twenty-Three Floors Above Chapel Street: What Prahran's Newest Tower Means for the Local Market

Stonnington Council received a planning permit application last month for a 23-storey residential tower at the High Street and Grattan Street corner in Prahran, a site that has sat vacant since a mid-2000s retail tenancy folded. The development, lodged by Criterion Property Group on 12 June, proposes 187 apartments across a mix of one, two and three-bedroom configurations, with ground-floor retail fronting the Chapel Street precinct. If approved, it would be the tallest residential structure within 600 metres of Prahran Market.

The timing is deliberate. Prahran's rental vacancy rate sat at 1.4 per cent as of the June quarter, well below the threshold at which tenants have genuine negotiating power, and median weekly rents for two-bedroom apartments in the suburb have climbed to $720, up from $610 eighteen months ago. Developers are reading that data the same way agents are: demand is outrunning supply, and the window for high-density approvals is open.

What the Site Means for Chapel Street and Beyond

The proposed tower sits roughly 200 metres north of Prahran Market, the 1891 Victorian market hall on Elizabeth Street that anchors the neighbourhood's identity as much as any street does. Agents working the Grattan Street pocket say the corridor between the market and Commercial Road has historically been undervalued relative to the South Yarra end of Chapel Street, partly because of its mix of ageing walk-up flats and light industrial holdovers. A 23-storey building changes that calculus fast.

Criterion's planning documents, which are publicly available through Stonnington Council's e-planning portal, flag 42 affordable housing units as part of the scheme, roughly 22 per cent of the total, offered under a Section 173 agreement tied to the permit. That component is being watched closely by advocates at the Prahran Community Housing register, which currently has 340 households on its waiting list. Whether those affordable units are priced relative to market rate or pegged to area median income is still being negotiated, and that distinction will matter enormously to how much pressure the development actually takes off the local rental market.

Neighbouring residents near the Windsor end of High Street have already begun organising through the Stonnington Residents Group, citing concerns about construction traffic through the narrow residential laneways off Grattan Street and shadow impacts on the low-rise Victorian terrace streetscape that runs toward Commercial Road. Council has set a preliminary hearing for 14 August.

Prices, Projections and What Buyers Should Know Now

Off-the-plan sales for comparable new Prahran apartments, specifically the 18-storey Caulfield Lane project that settled in late 2024, came in at between $680,000 and $1.15 million for two-bedroom stock. Industry sources suggest Criterion will price the High Street tower toward the upper end of that range, with three-bedroom units likely to open above $1.4 million. Pre-sales are expected to launch in the fourth quarter of 2026, ahead of a formal permit decision.

For existing owners in the pocket between Malvern Road and Commercial Road, the news is mixed. New high-density supply historically compresses the price premium on older apartment stock in the short term, particularly the 1970s and 1980s walk-up buildings that make up a large share of Grattan Street's current rental inventory. Owners of those properties may face softening yields for 18 to 24 months post-completion, even as land values in the broader precinct are lifted by the implied density signal the tower sends.

Buyers considering off-the-plan purchases in the tower should note that the planning permit process could extend well into 2027 if the August hearing prompts a VCAT referral, a common outcome for developments above 15 storeys in established residential zones. Anyone relying on a settlement date to synchronise with another transaction should build at least a 12-month buffer into their planning. Independent legal advice on sunset clause terms is essential before any deposit changes hands.
