The split-level floor plan is a popular alternative to single-level living. In split-level homes, living rooms or other communal spaces are offset by a quarter-floor up or down, creating varying room depths. Small steps lead from one room to another. Generally, the split-level layout also resembles an open floor plan with different heights.

History of Split-Level Construction

The trend of staggered levels originated in the U.S. After World War II, the U.S. experienced a significant baby boom, prompting the search for new ways to improve suburban living conditions. The new architectural style allowed for more living space on smaller lots.

Although the houses were more compact, they were more affordable, making this construction style highly attractive. The open and relaxed floor plans were also a welcome change from traditional Craftsman homes.

Features of a Split-Level House

In a split-level house, it feels as if there are no walls. The open floor plan, which extends through various areas and levels, makes this construction style unique. The half floors, which usually lack proper boundaries, offer an almost panoramic view.

The main levels in a split-level, often consisting of communal spaces like living rooms, kitchens, and dining areas, are usually directly connected. Rooms requiring more privacy are more or less out of sight, located a few levels lower or higher. In a split-level house, there are no individual floors; rather, everything is separated by half staircases.

Unique Floor Plans

Living on different levels allows for creative expression, leading to interesting and individual floor plans. It’s not uncommon for these homes to have plenty of natural light. Floor-to-ceiling windows and skylights allow enough light to enter the house, brightening even darker areas.

A split-level is also well-suited for a house on a slope, as the floor plan often needs to be terraced due to the steep location. From the outside, this construction style is mostly recognizable by the different levels and room heights. In some split-level houses, the lower levels often contain a garage with an adjoining half-basement and living room above.

Creating Individual Zones

A split-level house allows for the creation of many private zones, helping individuals to retreat. Separating living and sleeping areas already provides a certain level of privacy. Additionally, dividing the floor plan into different zones offers space for work, relaxation, and hobbies. Integrating partitions and custom-built features can better delineate these areas.

Partially open fireplaces located between two levels offer a visual appeal and create a subtle separation between areas. Different ceiling heights can also create varied atmospheres. Low ceilings can provide coziness, while high ceilings exude a touch of luxury and make the room appear larger.

Watch Out for Tripping Hazards

Since this construction style involves climbing stairs, the constant up and down can pose a safety risk for some people. There is a potential fall hazard, especially for children and seniors.

Additionally, the split-level house is not particularly wheelchair accessible. Therefore, it’s important to consider whether such a floor plan is practical beforehand.

Split-Level from the Outside

This style often varies in its construction, but the half-story heights have typical features that are easily recognizable from the outside. There are individual rectangular or square building sections that protrude forward. Large panoramic or double windows are also typical for the split-level house, as well as flat roofs and facades equipped with various materials.

Examples of Split-Level

Although it must be said that the original split-level concept has continued to evolve. Today, there are many modern interpretations of it.

The single-family house in Hamburg Volksdorf by “La‘ket Architekten,” for example, is characterized by a “compact split-level organization.” From the outside, this building does not differ from the surrounding single-family homes in terms of its facade, as traditional clinker bricks were also used. The flush windows allow a view into the interior, where the split-level organization is evident. The entrance is partially underground and can be reached via a sunken area.

Another example of modern split-level architecture is the Multi-Split Single-Family House by Deolmann Design. The interlocking split floor plan connects all areas, with access to the outside throughout. While the building is closed to the street, it opens up at the back. This house received the German Design Award 2024.
