Design and SketchUp model by Wentao Zhang as part of the IKEA China in-store design team; about 80% of the design work is my own. Photographs of the built room set by Wentao Zhang, January 2025. The visuals and drawings were made from the design model in Blender Cycles in 2026, with CC0 textures from Poly Haven and ambientCG; a ceiling and fourth wall were added for the visuals, and a few pieces changed on site (the drawer unit, chair and table lamp). Sheet B11-D05 is a research drawing based on the Beijing 2012 external-insulation guideline and national masonry and seismic codes. The posters in the room are AI-generated images.

IKEA plans its room sets at three price levels: low, medium and high. B11 is the low-price set, made for a teenager’s bedroom: about 12.6 m², planned only with off-the-shelf IKEA ranges and built on the sales floor. The set is open to the aisle on one side, so I put sleep, study, music and storage along the other walls and kept the middle of the floor free: a full-height PAX wardrobe with sliding doors and a run of wall cabinets over the bed on one side; the desk with a pegboard, open blue shelving and a glass-front media cabinet on the other. The back wall becomes the lounge, with a round rug, a bean bag, curtains and a striped blind, and spotlights on suspended ceiling panels light each zone on its own. I did about 80% of the design work, within IKEA China’s in-store design team.

01 Built

The room set as built on the sales floor, photographed in January 2025. From the aisle the eye runs past the desk and shelving to the lounge and the bed; the wardrobe closes the right-hand side.

02 The Plan

About 12.6 m², open to the aisle. The rendered plan, cut at 1.45 m, and section A–A from the design model show how every piece stands against a wall so the middle of the room stays open. The walls are drawn as the Beijing brick-concrete construction of sheet B11-D05: a 370 mm brick external wall with rock-wool insulation and 240 mm brick internal walls.

03 Four Zones

Sleep (Z1), lounge and music (Z2), study (Z3) and storage (Z4), each given its own part of the floor and its own hatch. The cut-away axonometric labels the furniture that makes each zone.

04 Layers

Read from the ground up, the design is a stack of independent layers: L1 ground, a dark oak floor and two rugs; L2 the freestanding furniture system; L3 the enclosure, with walls, poster wall, curtains and wall cabinets; L4 spotlights across the ceiling. Dash-dot lines register every layer to the four corners of the room.

05 Wall Construction

A research drawing at 1:50 of the wall a room like this most often sits behind in Beijing: the external wall of a 5–6 storey brick-concrete residential block of the 1970s to 1990s, with 370 mm solid clay brick, cast-in-situ ring beams, precast hollow-core floors and corner tie columns, shown after the city’s energy retrofit with 50 mm of rock wool (Beijing guideline for external insulation in old residential compounds, 2012, Table D). Storey height and openings are typical values, not a survey.
