Design Principles

At Gebler Tooth we combine many varied design skills under one roof, and are able to present a rounded approach to design and consultancy commissions. We combine design flair with pragmatism. We take pride in understanding Client needs, and being thorough in investigating processes, evaluating and prioritising requirements in order to determine designs that are complete and an accurate reflection of the Client brief.

Through our close associations with other specialists, we ensure our designs are complete, tested and durable. The consultancy services we can provide you extend from initial feasibility studies through detailed design and project coordination to handover and occupation for projects ranging from the simple to the highly complex.

We firmly believe that our size, specialisation and commitment to continuous director level involvement in every project give our clients a unique service that is hard to match.

We take safety seriously; from the outset of projects, safety by design is a principle that is enshrined in our design and consultancy approach to all projects. We have embraced the role of Principal Designer positively, with the attendant impacts it has on our consultancy remit.



Team GB House – Main area


We are committed to sustainable architecture, addressing growing concerns for the long term impact development has in the global environment.

Our belief is that architecture and design should address life cycle cost and energy use; that materials come from managed resources and that product process, plant and equipment do not pollute the environment. Creating buildings that have inherent flexibility allowing them to adapt to change rather than require development.

We are committed to delivering sensitive and efficient buildings in harmony with their environment. Our established Environmental Management System for Designing Buildings, is championed by the Sustainability & Technology Director to assess the impact our design solutions may have on the environment. This system is organised in a logical sequence from site location issues through to project and facility management and is used from the earliest stage of projects as a vehicle for discussing appropriate sustainable opportunities and challenges.

Through our Environmental Policy we adhere to, develop and promote a holistic sustainable approach in both the operation of the company and in the services we provide to our clients.
