Toohey Miller

Compelling property that enriches the human experience.

Illuminating culture and place through bold property endeavours.

Our Legacy

Toohey Miller and Company was an eponymous architectural business established in 1955, with a reputation for contributing to the fabric of inner Sydney. Toohey Miller's grandson, Nick Couloumbis, has since contemporised the brand into a bold property development business, conceived out of a desire to further this legacy and deliver architectural excellence in every project, without compromise.

Toohey Miller is a property development business active in Sydney’s most prized and gentrifying locations with a reputation for marquee and architecturally significant projects. All Toohey Miller projects aim to complement and enhance the built and natural environment through curating the industry’s leading architects, designers and consultants.

Our Partnership

Toohey Miller partners with the industry’s most distinguished consultants, architects and construction partners in every project we encounter. Every TM partner has an alignment in vision and values. We share an unwavering commitment to our customers and improve our place and context through stellar projects and distinctive design.


Toohey Miller recognises that the privilege to undertake business today carries a profound social duty. This ethos complements our architectural commitment to context and place.

The days of excess and indulgence in business are behind us and profit is secondary to good environmental and social governance in the interests of our customers, communities and environment. 

We make a concerted effort to ensure sustainable design and construction, and in doing so, attempt to make inroads towards carbon neutrality.
