Best Interior Design Studios for a Project in Bangkok
Three practices for a Bangkok interior. Compare the type of space, the published work and the appointment your project needs.

The studio you choose for a Bangkok interior should understand the spaces you want to develop. A restaurant brings dining, arrival and service together. A workplace has another set of uses, while a private home needs rooms shaped around its occupants. Start with the brief and compare relevant work before agreeing the design role.
AD’ Design Studio publishes this editorial selection and is included below. Profiles appear alphabetically. The selection considers stated interior design services and identifiable project references.
AD’ Design Studio: connected settings for dining, work and private use
At KOI Restaurant in Bangkok, AD’s restaurant interior design brings together arrival, dining, conversation and the bar. Warm timber, a long counter and pendant lighting give the room depth. Booths and freestanding tables provide different dining settings.
Sathorn Lounge & Office, also in Bangkok, is a different kind of commission: a loft combining work, entertaining and a place to rest. A stone-clad screen separates the settings, with a bar, lounge and desk in a connected interior. This is a private mixed-use reference, distinct from a commercial restaurant.
Through Interior Architecture & Design, AD’ develops the complete interior for the agreed spaces with your appointed architect and specialists. For a dining venue, explore the restaurant design appointment; for an office, the workplace route helps frame the discussion.
Department of Architecture: architecture and interiors
Department of Architecture is a Bangkok-based practice working across architecture, interior architecture and related disciplines. Studio. Its official portfolio identifies Le Du Restaurant in Bangkok, dated 2023.
For a restaurant, use that reference to discuss the relationship between the dining space and the building. Establish which layouts, details and fit-out documentation the appointment would cover, and how the architectural and specialist work would be coordinated. The project page identifies the case; the proposal should define the design, site and implementation responsibilities for your venue.
PIA Interior: hospitality and workplace references
PIA Interior’s studio page describes experience in the design and execution of hospitality, residential, corporate and other interiors. Studio. Its homepage lists Thien Duong Restaurant at Baan Dusit Thani and Chia Tai Headquarters in Bangkok. Selected work.
The Chia Tai Company Limited case is listed under Corporate & Finance. For an office, ask which parts of that appointment relate to your own spaces. Compare the design documentation, specialist coordination and implementation support proposed, including who would hold furniture and construction contracts.
Compare the interior and the team arrangement
A restaurant reference and an office reference answer different questions. Discuss the studio’s role on each project before using it to assess your own brief.

Brief the studios for the same spaces
Identify the property, its current condition and the rooms or areas included. For a restaurant, describe the intended dining experience and the operational team involved. For a workplace, explain who uses the spaces and what must continue during the work. For a home, describe your routines and the rooms you want to connect.
Share plans and the roles already assigned. Agree who develops each package, who reviews it and who handles building work and local requirements. The Thailand project route provides another way to discuss an AD’ appointment.
Share the space, the stage reached and the team already appointed. AD’ can discuss the complete interior design work for your home or business.
