Madison Ave Duplex

We created a comfortable and functional open-concept home for a young family by combining three penthouse apartments enhanced by a 5,500 sq ft roof deck. Challenges: Build new kitchen over terrace space to bring light into apartment, rebuild existing brick bulkhead with extensive structural work to support new water tower, install custom steel staircase with tight tolerances in finished stairwell. Creating an open floor plan with structural and mechanical constraints required carefully balancing the owner’s budget and the design team’s vision. Streamline’s role was GC, and we self performed the millwork.
