What Gebler Tooth does

Gebler Tooth (legally Gebler Associates Limited, company registration 01835047) is a private, RIBA Chartered architectural practice established in 1984 and headquartered at Two World Business Centre, Newall Road, Hounslow, directly at London Heathrow. The firm specialises in technically complex architectural projects within the aviation and logistics sectors, delivering RIBA Stages 1-7 from feasibility through to handover, and operates with a team of 50+ professionals combining architectural design, operational planning, interior architecture and technical consultancy. Service lines include Architecture & Interiors, Master Planning, Materials Handling (with a focus on aviation baggage system redesigns) and Project Consultancy, serving enterprise clients such as Heathrow Airport, Farnborough Airport, British Airways and Gulfstream.

The practice has developed proprietary digital tooling through an in-house Digital Studio (GTA-i). Mosaic-i is an industrial master planning tool that generates between 100 and 10,000 site layout options algorithmically based on parameters such as building size, coverage, parking and yard configurations, with outputs exportable into Lumion for visualisation. OPERA is an AI-powered office planning platform, developed in collaboration with Workplace Futures Group with Innovate UK support, that combines AI with spatial analysis to test alternative layouts, circulation strategies and seating arrangements to maximise workplace flow efficiency. These tools enhance design accuracy and option generation but are positioned as productivity enhancements to a professional services workflow rather than as standalone commercial software products.

Gebler Tooth generates revenue through project-based professional services contracts negotiated directly with enterprise clients, typically on a multi-year basis across RIBA Stages 1-7. Fees are quoted per project based on scope, complexity and work stages; no public price list is disclosed. The firm is wholly owned by its founding principals — Sasha Gebler (Chairman) and David Tooth (Managing Director), both Cambridge-educated architects — with director Peter Fennell as a long-standing creative lead. No external investment, parent company or acquisitions were identified. Marketing is content-led and organic (LinkedIn, Instagram, Twitter/X, blog/news), and distribution is exclusively through direct enterprise engagement and competitive tendering for specialist aviation and logistics work, with the geographic footprint limited to the UK.
