Collaborative Team

The team boasts a high level of project management experience in co-ordinating high profile and complex projects. This experience has proven highly effective in exposing and resolving significant challenges.

We develop our staff to become confident and skilled in creative problem-solving at all levels and in all aspects of the job. Every project is unique and we respond by listening and with a ‘can do’ approach. Directors continue learning through hands-on experience of delivering projects from inception to completion – and share new skills and knowledge with staff. This approach has resulted in a loyal, communicative team and good staff retention.  All projects are overseen by an experienced director.

Technical Ability

We are an RIBA-chartered practice which meets new projects with the technical ability to fuse creative, yet pragmatic thought. We look to provide specifications that are achievable and sturdy using research and best practice. In the past, we have developed new products with local suppliers in order to achieve historic finishes using modern materials. We produce models and test ideas through prototypes, and work closely with suppliers, manufacturers and contractors to develop robust, practical and value-for-money solutions.

Skill development, empowerment and learning is at the heart of everything we do.
