Inside the Bellevue Hill mega-mansion battle that pitted a Silicon Valley millionaire against 46 neighbours over harbour views

By MADELEINE DAMO - WEALTH AND WORKPLACE REPORTER Published: 13:26, 1 August 2026 | Updated: 13:26, 1 August 2026 A fintech entrepreneur and young rich-lister has had his plans for a spectacular eastern suburbs mansion knocked back, with the court ruling it would 'monopolise harbour views' on the exclusive street. Stephen Dash, who was one of Australia's first tech exports to crack Silicon Valley with his student loans business Credible, took his $16million plans for a Bellevue Hill mansion to the Land and Environment Court last month to appeal a previous refusal.  Mr Dash, whose estimated net worth is $480million, purchased three neighbouring properties at Victoria Road and Drumalbyn Road, with the intention of redeveloping them into a sprawling harbourside estate for his family.   One of the properties Mr Dash reportedly snapped up for $33million in 2023 was the deceased estate of property developer Tom Bruer and his art dealer wife, Eva.  The 3,333sqm site, comprising three 'battle axe blocks', currently hosts a three-storey house and two semi-detached dwellings. The plans, first lodged in August 2024, sought to knock down all three dwellings and build in their place a nearly 12m tall multi-storey mansion featuring eight bedrooms, a home cinema, tennis court and wellness centre. Also featured in the plans were six car parking spaces, a tennis court, a wine cellar and an outdoor kitchen.   On June 19, 2025, the proposal was formally refused by Woollahra Local Planning Panel on the grounds it would have an 'unacceptable' impact on the views of neighbouring properties, and did not minimise view loss. Stephen Dash bought three neighbouring properties at Victoria Rd and Drumalbyn Rd, with the goal of redeveloping them into a harbourside estate.

A report by the Woollahra Local Planning Panel reveals that 82 objections came from 46 different residents, including 34 residing in Bellevue Hill. At least 20 of the objecting residents wrote more than one submission, with one neighbour lodging ten. Two Victoria Road neighbours were singled out as the most likely to be adversely affected, with the proposal putting their 'high quality' views of the harbour, Point Piper and Rose Bay Marina at risk. In its assessment report, the planning panel included an example of how a neighbour's ocean views would be blocked, describing the impact as 'negligible'. Planners' efforts to amend the proposal, first by aiming to reduce the building's bulk and view impacts, and then by removing a chimney and decreasing the roof by a metre, were to no avail.  Following a failed attempt at conciliation between the parties in October 2025, the matter was listed for a two-day hearing from June 23 to 24 last month. Victoria Road neighbour Penelope Kontopos, who became a second respondent in December 2025, also joined the proceedings to object to the appeal.  The main points debated during the hearing were whether the multimillion-dollar views could be 'adequately' shared and whether the building's height could be considered acceptable. In their appeal, lawyers acting on Mr Dash's behalf told the hearing the proposal was 'acceptable' and that the impact on views enjoyed by Victoria Road neighbours would be 'minor to moderate'.  Ultimately, Acting Commissioner Helena Miller dismissed Mr Dash's appeal. The plans, first lodged in August 2024, sought to knock down all three dwellings and build in their place a nearly 12m tall multi-storey mansion featuring eight bedrooms, a home cinema, tennis court and wellness centre.

'I find that the proposal does not provide for the adequate sharing of views and that it amounts to a monopolisation of views with the proposed new dwelling achieving harbour views over three full levels,' she said.   Acting Commissioner Miller also described the likely impact on the next-door neighbour's harbour views as 'devastating and severe'. The appeal was dismissed by the Land and Environment Court and the original decision by Woollahra Planning Panel to refuse the development application was upheld.
