Additions & Alterations Architectural Services
KMJ Enterprises specialises in the sensitive design of building additions and alterations for residential, commercial, and mixed-use properties. Our approach focuses on integrating new spaces seamlessly with existing structures while improving usability, compliance, and long-term performance.
We manage the full process — from assessing existing buildings and exploring design opportunities, to preparing compliant drawings, securing municipal approvals, and coordinating construction documentation. Every intervention is carefully considered to respect the original architecture while responding to current and future needs.
Our approach combines creative design thinking with technical precision, regulatory compliance, and close collaboration with engineers, consultants, and contractors — ensuring projects are delivered efficiently and to the highest professional standards.
