House with Skip Floors｜Introduction to Examples by Floor Plan & Room Type Author: Qurasuki Editorial Department

A split-level floor brings a sense of spaciousness even to a limited site. Its appeal lies in its ability to zone areas using only level changes, without walls or doors, allowing sightlines to extend deep into the space and creating a feeling of expanse beyond its actual area.
The height variations from these level changes are also effective for lighting and ventilation. By strategically placing windows that take advantage of the different levels, you can bring in light from above or allow air to flow diagonally, enjoying an atmosphere that changes with the seasons and time of day. Structurally, since the floors are supported at multiple levels, the placement of beams and columns, as well as ensuring seismic resistance, is crucial.

Adding a Dynamic Feel to an Open-Plan LDK. A Three-Dimensional Gathering Space Created by a Split-Level Floor. House with Skip Floors ｜Stylish Living-Dining-Kitchen Space

Incorporating a split-level floor into an LDK naturally creates multiple living spots within a single space. For example, a space in a corner of the living room raised by a few steps can function as a second living area where the family can enjoy reading or hobbies. The level change gently divides sightlines while still allowing sounds and presence to be felt, maintaining a comfortable sense of distance.
The change in height also influences ceiling heights and window placement, creating a rhythm in the space. You can enjoy different atmospheres at different times of the day, such as light pouring in from high windows and calm shadows spreading in lower areas.

Combining a split-level floor with a terrace makes the connection between inside and outside even more pleasant. By placing the terrace half a level up from the interior, sightlines can extend further, creating a lifestyle with the scenery as a backdrop.
The indoor level changes are reflected in the outdoor space, creating an intermediate area that can be furnished with benches or plants. This space can be used for multiple purposes, such as a spot to enjoy morning coffee or a waiting area for children before they start playing outside.

The true potential of a split-level floor is realized when combined with stairs. Connecting multiple floors with short flights of stairs makes movement rhythmical and creates a sense of circulation throughout the entire space.
Small landings can serve as places to sit and read or as gallery-like spaces to display decor. The circulation path itself creates scenes of daily life, transforming the staircase from a mere means of transit into something more.

A Three-Dimensional Feel Reflected from the Internal Structure. An Expressive Façade Created by a Split-Level Floor. House with Skip Floors ｜Stylish Exteriors

A split-level floor, with its internal level changes reflected on the exterior, creates a rich three-dimensional feel and rhythm for the façade. Differences in floor levels bring variation to window heights and eave lines, allowing the building to harmonize with its surroundings while highlighting its unique character.
During the design phase, careful consideration must be given to waterproofing, insulation joints, and seismic performance. Adding balconies or small roof terraces at the level changes can also enhance the appeal as outdoor living spaces.
