About
NSW Terraces and Duplex, Specialist Duplex Architecture Led by Mounzer Mortada
We are the duplex, terrace and LMR practice of M Cubed Architects - a Sydney residential studio with 20+ years and 3000+ completed projects. We exist for one thing: getting well-designed dual occupancies approved on Sydney blocks, especially the difficult ones.
Feasibility first, then design
Most duplex projects fail expensively: plans drawn before anyone checks the block can support an approvable design. We flip that order, feasibility and approval strategy first, then design to the pathway that gets you over the line.
