Residential and multi-residential projects

C4 Architects provides building design, architecture, and building project management services on a number of award-winning projects. These range from small-scale renovations through to multi-residential projects and bespoke new contemporary homes, in both rural and urban settings.


Sustainable and green home design

Our residential and multi-residential architects take a first-principles approach to environmentally sustainable design, ingraining sustainability into every stage of the project. As sustainable architects, we carefully consider sun orientation, material selection, thermal performance, and the use of recycled materials to create homes that reduce energy consumption, maximise natural cooling and ventilation, and are constructed from recycled materials.

Project examples:

Grange Townhouse

Binya Street Houses

High-end and luxury residential architects

We specialise in high-end and luxury residential architecture – designing homes that are refined, deeply personal and thoughtfully connected to their surroundings. Our approach balances contemporary living with consideration for landscape, context and heritage, with carefully considered details that bring a lasting sense of warmth, quality and sophistication to each and every home.
