Songpa 26 Pyeong Office Interior

An exposed ceiling and stainless-steel H-beams for a calm industrial interior

Office: interior design, construction and cost estimates

Hello! I am Ham Young-ju, a designer at Goodterior :)

Today's project is a 26 pyeong office interior in Songpa. Working with a ceiling height of 2385mm, we used an exposed ceiling and clad the structural H-beams in stainless steel, combining them with indirect lighting for a bright, open atmosphere.

The client wanted a raw character without visual discomfort or an enclosed feeling during work. Gray walls and wood flooring create balance, while glass partitions maintain open views.

Careful adjustments to materials and construction reduced the initial plan of 4000 to around 3200, bringing a restrained industrial atmosphere into everyday office use.

Let us take a closer look at the key spaces.

Floor plan

This 26.8 pyeong Songpa office has a 2385mm ceiling, so we exposed it and used stainless-steel H-beam cladding to reflect light. Indirect and recessed lighting provide comfortable, even desk illumination.The layout has central open desks, with the meeting room and director's office on one side and pantry and storage on the other. Glass partitions and curved walls create natural circulation, with places for team meetings and quiet calls.

Open office

The exposed H-beam ceiling is finished in stainless steel, with upper indirect lighting and track lights providing comfortable, even brightness despite the low height.
4-person desk clusters and low cabinets run along the windows. 900mm aisles allow easy circulation, and disassemblable modular furniture simplifies delivery without an elevator.

Meeting room

A central position makes the room easy for the team to access. Glass partitions define it, with curtains providing privacy when needed.
Soft indirect lighting above the table and whiteboard paint on the wall make written notes easy to see.

Director's office

Positioned independently at the far right, this room is slightly removed from outside noise. A curved glass partition at the entrance creates natural circulation.
The desk faces the window, with shallow built-in cabinets across the wall. Tops and cabinet components are made in sections for easy stair delivery.

Kitchenette and storage

Long, straight upper and base cabinets follow the curved circulation route. Indirect lighting beneath the worktop brightens the areas used most often.
Easy-clean floor tiles and a position set back from the open office help limit the spread of noise during use.

Let us look at the overall design concept.

For a kitchenette used during brief work breaks, we kept circulation simple and focused on the most-used areas. A dark gray plaster wall creates calmness, while a white worktop and undermount sink make splash marks less noticeable.A long linear light distributes brightness evenly despite the low ceiling, and handleless matte base cabinets are easy to clean.

Notes

This 26 pyeong office interior in Songpa responds to the request for a bright, open feel despite a low ceiling through an exposed H-beam ceiling and a considered lighting plan.

The H-beams are clad in stainless steel, with concealed upper indirect lighting reducing glare and evening out desk illumination. An industrial atmosphere runs throughout.

To retain openness while reducing unwanted views during meetings, we used glass partitions, horizontal striped film, and curtains. With no elevator on site, modular furniture and divided packaging allowed materials to be carried safely up the stairs.

If you have any questions, please leave us an inquiry. We will be happy to help :)
