These days, many people work on interior design in their own style before moving into the apartment. You have to choose a lot from one to ten. Among them, I think many people will think about the veranda expansion and non-expansion. If you expand the veranda, you will find it convenient to use a larger space. However, if we expand, it is difficult to block all the temperatures in the cold winter with just one outside window.

The lower rail was constructed with a slim lower rail that fits the residential area. The normal (primary) lower rail has approximately 3 cm protruding above the floor surface. You can feel uncomfortable in an apartment (home) where you live without shoes. If a foot accident occurs on the lower rail due to not wearing shoes when passing, it can lead to serious injury. When moving large objects to the veranda, the lower rail above the surface can also be more difficult.​

In consideration of this, the lower rail was designed to fit the apartment type (residential), and the protruding part of the sea surface was lowered to about 15cm.The minimal exposed lower rail significantly reduces foot discomfort.
