Swansea-based entrepreneur wins national recognition at Stelios Awards
The prestigious awards, founded by Sir Stelios Haji-Ioannou, recognise young UK entrepreneurs building high-growth businesses that create jobs and deliver lasting impact. Over 180 founders from across the country applied, with Dorian emerging as one of just three winners nationally — and the only winner from the construction and housing sector.
At just 29, Dorian has already built one of the fastest-growing development companies in Wales. From humble beginnings helping his parents manage their small property portfolio, he launched Castell Group to meet the urgent need for affordable homes. Since 2019, the company has delivered over 200 homes, has 280 currently under construction, and a land pipeline valued at over £220 million.
“This recognition from Sir Stelios and the Foundation is a real honour,” said Dorian. “The award funding will go straight into unlocking more social housing sites across Wales. There are over 1.5 million people on housing waiting lists in the UK — this work is more urgent than ever.”
Based in Swansea, Castell Group now employs over 60 staff across departments including construction, land and development, commercial, finance, and marketing. With continued plans to scale across the UK, the business has become a national role model for capital-light, client-led delivery of affordable housing in partnership with local authorities and housing associations.
The Stelios Philanthropic Foundation, which has donated over €84 million to good causes globally, launched the UK Young Entrepreneur Awards to highlight and accelerate businesses that drive job creation and long-term social impact. Past award recipients include startups in AI, tech, and sustainability. This year’s winners included an AI robotics company and an electric vehicle charging firm — with Castell Group standing out as a mission-driven housing developer.
“I’m incredibly proud of the Castell team — they were watching the awards live from our boardroom in Swansea,” Dorian added. “This award is a testament to their hard work, and to the potential for Welsh businesses to lead the way in solving national challenges.”
