Aircraft cabin interior design.
D2Bridge is an aircraft cabin and interior design consultancy in the Seattle area. We plan cabins around the people who fly in them and the crews who work in them, then carry the design through materials, mockups and handover to your engineering team.

Every inch is a decision.
In a cabin, comfort, weight, certification, maintenance and brand all compete for the same few inches. Our job is to make those trade-offs visible early, test them with real people, and arrive at a layout that passengers enjoy, crews can work in and engineers can build.
We work as the design team inside your program, whether you are an OEM defining a new aircraft, a completion center outfitting a business jet, an airline refreshing its product or a supplier developing seats, monuments or cabin products.
Layout & zoning
Seat counts, zones, service flows and sightlines, from early sizing studies to a full cabin plan.
LOPA · ZonesSeats, monuments & stowage
Seating, galleys, lavatories, stow bins and partitions designed as one family, with ergonomics and maintenance access in mind.
Seat · MonumentAccessible cabins
Lavatories, aisles and controls that work for passengers with reduced mobility and for the crews who assist them.
PRMColor, material & finish
Palettes and materials chosen with aerospace fire and weight requirements in mind, and with a clear brand story.
CMFCabin interfaces
Lighting, passenger controls and screens built into the furniture, so the digital layer feels like part of the room. See HMI & cockpit design.
IFE · HMIMockups & visualization
Physical and digital mockups and visuals that let stakeholders sit in the cabin before it is built.
Mockup · VizA business jet planned like a home.
For Outbound Aerospace, we designed the exterior, interior and cabin experience of Ozark, a blended-wing-body business jet concept measuring 115 × 100 × 31 ft. The wide airframe let us plan zones instead of rows: a raised forward lounge with the pilot's view, a bar and social lounges, dining, and a private suite with a bedroom and shower.
The palette comes from the Lake of the Ozarks: limestone tones, wood veneers, polished metal and woven textiles, chosen with fire and weight requirements in mind and favoring bio-based panels, recycled upholstery and parts that can be taken apart and reused. Ozark was named a finalist in the 2026 International Design Excellence Awards (IDEA), run by the Industrial Designers Society of America.
Two seats, sized to the pilot.
For DBT Aero's new two-seat aircraft, we set up the cabin configuration and sizing, designed the canopy and created the exterior liveries shown at the 2LX launch in 2025. In a small aircraft, seat position, reach and sightlines decide how the aircraft feels to fly, so we sized the cabin around the people in it first.
Aerospace depth, senior attention.
Konstantin Ziman, our co-founder and Managing Director, was previously Head of Design at Eviation Aircraft, the developer of the all-electric Alice commuter aircraft. Senior designers lead every project, from first sketch to handover.
Our consultant Blake Emery is a former director of differentiation strategy at Boeing, with design patents and a key influence on the 787 Dreamliner and Boeing Sky Interior cabins. He brings research in behavioral and consumer psychology to how passengers actually experience a cabin. Read his view on the inclusive cabin.
Our European partner studio, Almadesign, adds transport and interior design capacity. Together we designed Ozark.
Passengers first. Certifiable always.
Understand
Passenger and crew research, the mission and operator requirements, and the regulatory context, including FAA and EASA.
Experience
Journeys from boarding to deplaning, ergonomics and service flows, mapped before form.
Form
Layout, seats and monuments, CMF and lighting, visualized so decisions can be made early.
Realize
Physical and digital mockups, design-for-manufacturing detail and a clean handover to your engineering and certification teams.
Common questions
More in the services FAQ
What does an aircraft cabin design consultancy do?
It plans and designs the environment passengers and crews share: layout, seating, monuments such as galleys and lavatories, stowage, lighting, materials and the interfaces passengers touch. D2Bridge works from early concepts and sizing studies through mockups and design-for-manufacturing detail, as part of your program team.
Can you work within FAA and EASA certification requirements?
Yes. We design with certification in mind, including flammability, weight and accessibility requirements, and work alongside your engineering and certification teams, who keep responsibility for compliance and approval.
Which aircraft types do you work on?
Business jets, commercial aircraft and new aircraft types. Recent work includes the Ozark blended-wing-body business jet concept for Outbound Aerospace and the two-seat cabin of DBT Aero's aircraft. Our co-founder previously led design at Eviation Aircraft.
Can you help us design a more accessible cabin?
Yes. U.S. Department of Transportation rules are bringing accessible lavatories to new single-aisle aircraft with more than 125 seats, and accessibility is becoming a competitive advantage. Our consultant Blake Emery, a former Boeing director of differentiation strategy, writes and advises on inclusive cabin design.
How do we start, and how is the work scoped?
Tell us about the aircraft, the stage of the program and your timeline through the contact form. We usually scope a defined project, such as a cabin concept or a mockup, or reserve monthly hours with Studio on retainer for ongoing support.
