Also in New Farm, 29 Mark Street sold pre-market for circa $9 million while still under construction. Set on a 540sqm block and due for completion next month, it was also bought by a returning expat. A further Ascot home has also just sold for $6 million, with the address withheld.
Mr Lancashire said demand in the $5 million-plus bracket had surged in recent weeks.
"We have seen a massive uplift in buyer inquiry over the school holidays. The phone has been incredibly busy, and the depth of buyers at the top end right now is something we haven't seen in some time," he said.
"The high-end market in Brisbane is firing."
A growing share of buyers is being found well beyond Queensland, with targeted social media campaigns run through the agency's database generating between 100 and 500 inquiries on average.
"Our social media reach through our database is bringing us a huge number of interstate and international buyers, and we can back that with data. Using NurtureCloud alongside our in-house social media team, our targeting is so finely tuned that these are genuine, qualified buyers," Mr Lancashire said.
He said the way prestige buyers behave had also changed.
"Buyers never used to be loyal. Now they latch on to the advisors and agents they trust," he said.
"At this end of the market, it's crucial to deal with an agent who has runs on the board and can demonstrate both a buyer pool and a strategy for reaching it."
