Existing buildings

New buildings add only one percent to the building stock each year. The remaining 99 percent of buildings require regular renovation and refurbishment to meet ever-changing building user demands or recover service life. Our wide-ranging expertise enables us to meet client’s needs - ensuring existing buildings provide economic, social, and environmentally sustainable benefits.

We believe that simply maintaining the built environment and limiting deterioration is not enough. Our aim is to ensure buildings remain as living, working structures - meeting the needs of current and future users - whilst minimising their impact on the environment. To achieve this goal, we use a systematic and holistic approach to ensure the full potential of an existing building is reached before they deteriorate and become unusable – utilising all aspects of the building.

Historic buildings

Historically significant buildings require a special approach - understanding or ‘listening’ to the building is the key. We have worked on internationally important historic buildings and sites – collaborating closely with historic building protection authorities – providing solutions that are sympathetic to the historic building fabric and minimising irreversible interventions.

Comprehensive renovation and refurbishment service

Experience is often the key to successfully renovating or refurbishing an existing building. 1:1 renovations are one of our specialties and we have provided solutions to many complex and multifaceted problems in existing buildings to realise our clients’ aspirations.  

We have a wide range of clients and no job is too small – we work on everything from maintenance plans and mould inspections to complete renovations.
