Our Company

London Stone Conservation are specialists in conservation and restoration for London’s built heritage. Our approach combines traditional craft skills and modern methods of efficiency. We enjoy working on a broad range of projects, offering our clients four expert service areas:

  • Building conservation and restoration
  • Ecclesiastic and monument conservation
  • Conservation of sculpture, objects and decorative surfaces
  • Carving and lettercutting

Founded by Stone Carver Florian Kirchertz in 2003, our aim has always been to provide sympathetic and informed interventions. Our team of expert craftspeople specialise in delivering complex programmes of work for listed buildings and monuments. Always sensitive to the needs of our clients and the areas we work in, we pride ourselves of working efficiently with minimal disruption to our clients’ own day-to-day activities.

We take as our logo the Lewis Pin, a relatively small tool used since Roman times to move, without brute strength, extremely large objects.  The Lewis Pin represents our roots in historic methods and the ability of our team to undertake large and complex projects.

Our work

London Stone Conservation employs craftspeople from a range of disciplines trained in historic and traditional techniques, with an emphasis on maintaining an innovative and creative approach to our commissioned work. This wealth of knowledge and practical experience can be applied to a variety of projects, from replacement work within the heritage sector to new work for commission.

We take great pride in our work, offering a pragmatic approach that combines historic processes and traditional skills with modern methods of delivery. Our industry memberships, accreditations and networks ensure that we are always at the forefront of developments and legislations in our field. Perhaps testament to our abilities are the long-standing relationships we enjoy with clients, such as HM Tower of London, the City of London and Highgate Cemetery.

Often our work has to balance many factors such as the physical constraints of a building to aesthetic considerations and values. We hold an in-depth understanding of the relationships between the practical and academic aspects of stone conservation, bringing a philosophical approach to safeguarding our built heritage.

London Stone Conservation is involved in projects throughout London and the surrounding area. Previous and current projects include listed properties, with clients such as City of London Corporation and Historic Royal Palaces.

Our team

Each project is led by formally trained and experienced crafts people, many of whom are graduates of the City and Guilds of London Art School’s conservation and carving departments, with which we have enjoyed a long relationship over the years. Our team are all trained in the production, installation and use of stone for a diverse range of architectural applications and needs. Over the years we have developed an extensive professional network of aligned craftspeople and experts in our sector, allowing London Stone Conservation to offer a wide range of capability.

Through our apprentice programme we offer newer members of the team opportunities to train and develop, passing on innate knowledge and skills from one generation to the next alongside their formal training and development programme.

Commissioning Work

We welcome all types of commission from memorials to public art projects. Often this area or work includes design and layout, traditional carving, stonemasonry, hand cut lettering, clay modelling, guilding, polychromy, mouldmaking and casting. London Stone Conservation is able to offer technical support at any stage of the design process or can take on the complete project from the initial inception to the execution of the work. We follow a traditional process for the commissioning of new work, starting with initial designs or scale models through to the final realisation of an object, allowing for client review at every stage.
