A Foundation 65 Years Deep

 The Duffie Companies are a specialized group of firms catering to the varied needs of long term residential and commercial real estate owners.   

WE THINK LONG TERM

We develop and importantly, hold, real estate.  We have found over the decades that as long term owners we often view real estate differently than more common “merchant" builders and developers whose primary focus is to build and sell.  While there is nothing inherently wrong with short term ownership, we have observed that our long term view often leads to more innovative, durable and sustainable approaches to real estate.  We embrace green building practices with a focus on durability and performance.  While most of our work is performed on our own account, we bring value to an expanding group of trusted partners who value our multi-generational view, our expertise in sustainable buildings, and our financial strength.

FOCUSED ON QUALITY AND DURABILITY

When you know that you are going to own and maintain buildings for decades 

focusing on quality, efficiency and durability come naturally.   Paying attention to long term value and sustainability has made us leaders in the development of high performance buildings.  Our projects enjoy strong financial performance while minimizing their impact to the environment.  

GROWTH THROUGH PARTNERSHIP

While most of our projects are developed and owned exclusively by and for The Duffie Companies, we have been honored to work with a growing number of valued partners.  We find the best partners to be those who share our long term perspective and consequently appreciate our attention to quality and resilience.  

We are a true "value added" partner bringing  a unique combination of financial strength, experience, and deep knowledge of building science to the projects of which we are a part.
