Committed to the long-term future of the building industry

Our History

How is all began

Calma Group started life in 2012 as a family run business known as A.L. Interiors.

We began working as a subcontracting firm for one of the UK’s leading hotel brands.

Since then, we have made the transition to Principal Contractor to have more control in the end services delivered to our clients.

We rebranded in December 2018 becoming Calma Group and have enjoyed working on bespoke, unique and innovative projects here in the UK, as well as being able to expand into the European market.

Our Values

Our values are to be open and honest to clients and workers and to support them at all times. We always look to professionally execute the goals set by all those we work with.

Our Vision

Our vision is to establish ourselves as one of the most innovative businesses in our industry. We aim to use a diverse and unique workforce who can face all the challenges we come up against, working closely with our clients and with each other.

Our Mission

Our mission is to provide safe places of work for all of our staff and to empower our operatives to fulfil their full potential, being led with the training and guidance of their colleagues and peers at Calma Group.

Our Team

Calma group is a growing company within the construction industry and we have grown from strength to strength since 2012, now offering full fit our services with our own skilled labour force and great office staff who continue development through our core values, vision and mission.

Andrew Lafferty

Managing Director

Andrew’s career started learning a trade through an apprenticeship leading him to become self-employed. After working as a self-employed tradesman for several years he decided to establish A.L. Interiors which organically became Calma Group. Due to this wealth of hands-on experience, he is familiar with the challenges a construction team face when they’re on a project.

Although we deal with large-scale projects, the family business values that started this company are still in everything we do. We want our clients to know that we care about their project just as much as they do.

“I’ve been fortunate enough for the last few years to have been involved in some of the most exciting projects in the hotel sector in the UK, and we’re now working on some projects in Europe.”

At every stage, we are dedicated to delivering projects to the highest standard. From planning, design & manufacturing, to on-site construction and project management.
