Situated in the heart of Taipei's metropolitan area, this interior design project is a high-ceilinged top-floor residential unit with its disadvantaged nature of the low beam line and the half-circle architectural form. However, with a thorough evaluation and resourceful planning, the designer has overcome all these obstacles by redesigning the staircase’s direction, redirecting the upper light source to the lower space, along with compressing and releasing the spatial focus. Accordingly, these remodeling procedures offer the old building a brand-new vision.
