We strive to have a cooperative and comfortable working environment with staff and directors, clients and contractors treated respectfully and acknowledged for their individual strengths. This outcome is derived from an office hierarchy that is as flat as possible. We strive to attend to the personal values and aspirations of all, providing a sense of ownership and belonging.
The Christmas card
Our annual Christmas card has become a feature of the practice. Each year the card includes a tableau of the office staff and directors making a tableau derived from an important work of art. As well as Seasons greetings, the card features a notable project that was constructed over the year and recent office news.
