Who We Are

Gebler Tooth is a RIBA Chartered Practice of Architects and Designers with our office based at  Heathrow. The practice was established in 1984 by Sasha Gebler and David Tooth and combines specialisms in various market sectors including aviation, work space and media, hospitality and leisure, sport and residential.

What We Do


With our team of some 50 staff we are able to offer a range of services that include architectural design, space planning and interior design and some more specialist services that, in their combination, are unique.

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. 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 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.

Through our close associations with other specialists, we ensure our designs are complete, tested and durable. The consultancy services we can provide 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.

GTA is Quality Certified to ISO 9001, externally audited by BSI.
