Better Multiplexes, Built Right
We specialize in constructing beautiful, modern multiplex homes that enhance existing neighbourhoods. Discover how we bring thoughtful design to life.
Redefining Urban Living
At Green Street Flats, we’re redefining city living—one multiplex at a time. We develop, build, and manage purpose-built rental apartments designed for community, sustainability, and lasting value. Our projects blend into existing neighbourhoods and reflect a commitment to thoughtful design, local engagement, and the belief that home should be more than a concrete box in the sky.
Thoughtful Design
We create apartments that are functional, beautiful, and built with intention—where no detail is an afterthought.
Community Focused
Every project is designed to connect people—not isolate them. We build homes that foster openness and interaction.
Sustainability First
From material choices to energy efficiency, sustainability guides every decision we make.
Purpose-Built Rentals
We don't retrofit—we build for renters from the ground up, delivering homes that feel right from day one.
Seamless Integration
Our multiplexes are designed to fit naturally into the neighbourhoods they join, both aesthetically and culturally.
Livable Alternatives
We offer a new standard of urban living—smaller scale, human-centered housing that balances comfort and design.
