Interview: Matt Baker

The story of The Marble Group is a testament to entrepreneurial resilience and vision. Founded by two young entrepreneurs, Theo Constanti and Michael Nicholas, the company has transformed from a modest garage-based operation to a stone fabrication powerhouse.

Constanti’s journey began with a personal challenge. At 17, he lost his hand, an experience that could have derailed many. Instead, it became a catalyst for entrepreneurship.

While studying at university, he developed exceptional telesales skills, learning the art of sales, advertising, and business management. His business partner Nicholas took a different path, leaving school at 16 to work at a marble company and later becoming a skilled stonemason, specialising in templating and fitting kitchen worktops.

A chance meeting in Cyprus led to the two entrepreneurs beginning a new venture into stone fabrication. Starting in a parent’s garage, the duo began with one job a month, gradually building their reputation through sheer determination and skill.

Their early approach was characterised by a willingness to take on challenges, saying yes to projects that others might have avoided.

In those early days, that willingness could sometimes create challenges. As Constanti explains: “I think the supply chain wasn’t as good as it is now. Sourcing products was difficult, and we were learning on the go. We just said yes to everything, because that’s what young business people do.

“I remember one early job where we agreed to work at Selfridges, which meant working throughout the night for a month, while still doing our daytime jobs and sleeping in between. Back then, we did all sorts of jobs for everyone, and it was very hard to manage.”

Indeed, the company’s client list reads like a who’s who of prestigious institutions. From Buckingham Palace to the British Museum, from Chelsea Football Club to Harrods, The Marble Group quickly established itself as a go-to fabricator for high-end projects. This wasn’t just luck – it was a result of its commitment to quality and innovative approach.

The ability to adapt has been crucial to the success of the company. When the market shifted from granite to quartz, The Marble Group was among the first to embrace the change.

Similarly, when ceramic surfaces emerged, The Marble Group was quick to incorporate these new materials into their offering. This agility has been a hallmark of its business strategy, allowing the team to stay ahead of industry trends.

The company in 2025

This year marks a significant milestone for The Marble Group. With a 10% growth in turnover and a recent kbbreview Retail & Design Award for Installation Company of the Year, it has really solidified its strong position in the market.

A recent £3.1 million factory purchase is more than just a property investment – it’s a strategic move to future-proof its operations, expanding its manufacturing space from 20,000 to 50,000 square feet.

Technology is at the heart of the growth strategy. The Marble Group has invested in cutting-edge equipment, giving customers even more options for customisation.

“We’ve actually invested in a slab scanner,” says Constanti. “Before we manufacture a job, it shows customers the way the veins will go on their worktops. And I think our continued investment into our software is very important. The buzzword right now is AI, and I don’t think it’s even about waiting until 2026 – we need to embrace it now.”

Talking of buzzwords, there’s a growing narrative around sustainability and how companies today approach sustainable practices. Constanti believes sustainability is at the heart of The Marble Group’s long-term vision.

“We’re committed to responsible sourcing, prioritising suppliers who use eco-friendly quarry practices and comply with agreed environmental standards.

“We’re reducing our carbon footprint by optimising energy efficient machinery and exploring renewable energies for our facility, like solar panels. Marble and coarse off cuts are repurposed through a local company, and we’re educating clients about the longevity of stone and natural stone alternatives.”

In an industry increasingly scrutinised for safety concerns, The Marble Group has taken proactive steps to address potential risks by investing heavily in protective solutions, as well as working closely with the Workshop Fabricators Federation to establish and maintain safety guidelines.

“Silicosis is a concern, and the industry must act decisively to protect workers and reassure consumers,” says Constanti.

“Transparency and control are the key. We’ve invested in the best in class dust suppression and air quality systems, and we’re working closely with suppliers to move to low silica or silica-free products.”

Culture

The company’s approach to talent is equally innovative. Its apprenticeship program focuses on young talent, believing that fresh perspectives drive innovation. As Constanti explains, “You can’t beat young people. Their ideas, their energy, the way they look at things has been one of the main reasons for our success.”

Training encompasses everything from cutting and polishing to installation, ensuring the company maintains high standards while embracing technological advancements.

The corporate culture is built on a powerful philosophy articulated through a poignant story Constanti often shares about two stonemasons. One sees a monotonous wall-building task, while the other understands he’s constructing a cathedral.

This metaphor encapsulates Constanti and The Marble Group’s approach to business – every job is an opportunity to create something meaningful. And the results speak for themselves. A significant percentage of their workforce have purchased their own homes, some coming from humble backgrounds.

Like many successful companies in the KBB sector, the ability to form meaningful partnerships is key – something The Marble Group embeds into its ethos.

Independent retailers – who account for 90% of The Marble Group’s business – have become true partners, not just customers.

“Independent retailers are absolutely crucial to our success,” says Constanti. “They provide valuable feedback, help us stay on trend, and understand the importance of high-quality stone products. They trust us to deliver tailored solutions to their clients.”

Future

The company has recently expanded into tile supply, acquiring a tile company to diversify its offering to existing clients.

Looking ahead, The Marble Group is thinking globally. A US operation is planned for 2026, complementing its new factory and recently acquired tile showroom. Constanti says the global stone market is projected to grow 4-6% through to 2030, with increasing demand for sustainable and versatile materials.

As the stone fabrication industry evolves, The Marble Group stands at the forefront. It’s not just responding to market trends – it’s helping to shape them.

From a garage startup to a big industry player, The Marble Group offers a refreshing alternative.

It’s not just cutting stone; it’s building cathedrals – creating opportunities, supporting communities, and proving that purpose-driven business can be both profitable and meaningful.
