This two-level old house in Shanghai has a total area of about 48 square meters. It needed to support daily living, work and client meetings, while the original stair disrupted the layout and the kitchen and bathrooms could not be extensively relocated.

Relocating the stair to the center allows platforms, built-in cabinetry, an island and masonry furniture to integrate living, work, gathering, dining, storage and bathroom functions within a 48-square-meter two-level home.Designer: Lu Haining

The brief was to accommodate living, work, meetings, dining, storage, laundry and bathrooms on both levels while retaining the original kitchen location and assigning a clear use to every structural element.
The stair is relocated first. Initial steps raise the stair zone and place it at the center of the ground floor, where it becomes the structure that divides and organizes the shared areas. This move releases one continuous wall for a western kitchen and full-height storage.
Below the raised stair, cabinetry, an island and a large table are combined to support work, meetings and dining. The masonry sofa is paired with wall cabinetry for display and storage, allowing seating and storage to define the room together.
Because the original kitchen position was difficult to alter, it is retained. The ground-floor bathroom gives up its shower and receives the washing machine, keeping laundry within the wet zone and making the kitchen easier to use.
Upstairs, stepped platforms run along the wall. They support the mattress and combine bedside storage, a multifunction desk and seating within one system of levels. Cabinetry on both sides adds storage for the bedroom and work area.
The upstairs toilet and shower occupy the ends of two corridors. Rather than using separate furniture to divide the plan, the project compresses functions through stair, platform, cabinetry and changes in level, allowing the 48-square-meter home to carry a program closer to that of a conventional 100-square-meter residence.
