Spiral staircase is not business ,but also artwork

We finished this spiral staircase today .

At the same time , when I am watching it, it reminded me how I felt when I saw it first time . They stand there gracefully,just like artwork .

When it stand in your house , you will feel it is friend ,which can accompany with you through all your time . It is just not a house , but real home .

Our staircase deserve to have it .

Welcome to NST Building , you will know what is beautiful !
