Our commitment to sustainable construction

We believe and subscribe to the responsibility of both respecting and protecting the environments we work in and the projects we are involved in – Not just for the benefit of our teams and clients, but for future generations.

To us, construction sustainability means creating structures and interior fitouts using process that are environmentally-responsible and resource-efficient throughout their lifecycle. In this area, natural stone stands as a sustainable alternative to conventional cement and concrete-based solutions, with a correspondingly lower carbon footprint to match.

Building with natural stone and other renewable resources means reducing waste and energy consumption, protecting natural and creating an altogether healthier indoor environment.

About Our Team Of Artisans, Management & Stonemasons In London

The CI Team draws on over three-and-a-half decades of experience in stone selection, processing and installation, informed by additional skillsets in contract administration & site management. Together, this leaves us positioned as a preeminent authority within the realm of natural stone both in the UK and wider Europe.

One major facet of our specialist skillset are the experiences of our founder, Colin McKenna. He was originally based in Italy, where he spent 12 years learning stone processing and installation while working for an Italian quarry-owning fabricator.

Owing to his ear for languages, Colin was quickly promoted to site manager and became the company interface with architects, main contractors and clients, overseeing international projects as far afield as Perth, New York City and the Cote D'Azur.

CI represents the culmination of this experience and the practical lessons learned therein, which we uphold with the following values:


A Commitment to Continuous Training

CI operates a highly skilled international workforce of CSCS-registered specialists, assembled across a variety of projects over several years.

However, we are never content to rest on our laurels. We constantly re-invest in our staff, equipping them with further professional qualifications not just to comply with the ever-changing web of regulations, but to enhance their skillsets on-site and ensure the longevity of their careers.

A focus on Long-Term Relationships

CI stands by the notion that the most fruitful professional relationships come from a place of trust and mutual understanding.

That's why we always have our eye on the long-term when it comes to expanding our professional network, as we find this translates to an improved service for our clients.

A Transparent Company Culture

We work in structured teams, with every 5 operatives reporting to a trained SSSTS- or SMSTS-accredited supervisor. Each supervisor, in turn, reports to a senior manager, they to a project manager and the project manager to Colin directly.

When it comes to the day-to-day running of operations, CI uses diligent online monitoring software to track the progress of projects, ongoing contracts and the HSQE adherence of the company at large.

A dedication to Client Communication

We maintain a policy of one point of contact for each contract, and the streamlined chain of command as detailed above means that something can be quickly escalated to the founder directly if necessary.
