Tristan’s principle design strategy for all types of building from small saunas to large master-plans is that the user comes first. For him it is vital that the users’ current and future needs are considered in all stages of the design process. This results in every design being treated as unique and being built in a way that it can be easily adapted for future needs. All of Tristan's designs carefully consider their environmental impact and their long-term sustainability.
As the director of UUSIark (est. 2006), Tristan has designed and built a number of house-extensions and loft-conversions both in the UK and Finland and has worked in collaboration with both large and small firms on a variety of projects. He has also competed in a number of European open architectural design competitions.

Tristan is currently a project architect for one of Finland’s most successful offices; JKMM Arkkitehdit Oy. Where he is currently working on various retail/commercial and residential projects.
