"We conclude our strongest quarter to date in 2024 with an exceptional performance from our sales teams, achieving €67.3 million in pre-sales and sales. The consistent sales and pre-sales performance in the first nine months of this year, together with a stable average selling price per square meter compared to 2023, highlights our ability to maintain strong results and the resilience of our business, year-on-year. Despite the complexities of the market, One United Properties remains the preferred choice for customers looking to upgrade their living standards. Our commitment to quality, transparency and delivering on our promises has cemented our position as a trusted developer in a market where supply is increasingly constrained. In an environment where trust is paramount, we have consistently demonstrated reliability to our customers, which remains one of our key differentiators in the market," said Victor Capitanu, Co-CEO of One United Properties.
