The main goal of this residential project is to create a comfortable silence inside a house with a new open atmosphere. It is also a challenge for the architect to keep the openness and provide comfortable silence at the same time.

Two squares that intersect with each other are set in this project plan. A well-balanced interaction between the openings and the wall structure of the house is also carefully considered.

The use of short stairs and skipping floors can transform the moving line into a fluid inside this house. The living area and sleeping rooms are connected by these short stairs.

A polished concrete finish in the kitchen and living room can give additional value to this house’s external light.

The first floor of this house has a lower ceiling than the living room so a more private and cozy feeling can be achieved. On this floor, there is a very special concrete spiral staircase. The thickness of the supporting slab is designed to avoid any necessity for a central pillar.
