Plants are no less complex than animals or humans, but they are under-researched in comparison. This project looks to connect scientists and visitors with flora above fauna and reintroduces the importance of imagination in science. Milestone is suggestive of the past as well as the future and moves with the ever-changing climate. Fragments of brick from previous buildings on site are incorporated into façades and paths. The materials used stem from a back-to-origins philosophy using local timber and limestone, finished with as few manufacturing processes as possible. The site includes a variety of habitats under different levels of control, with some areas wilder than others. Research residencies provide space for visiting scientists to stay and learn within wild areas, studying the relationship between humans and plants in urban rewilding. Trees grow to replace shading louvres and aspects of decay and re-use are considered through a plant waste energy system to generate electricity on site. The proposal borrows materials from the land, reveals its structure and uses screw piles to cause little disturbance to tree roots.
