In 2015 Ghilardi+Hellsten participated in a parallel commission for the new masterplan on Tiller, Trondheim. “The strip” in Tiller is highly dominated by big-box shopping, but Trondheim municipality and the largest property owners of the site seek to develop the area into a future urban center for the surrounding residential neighborhoods. Ghilardi Hellsten is currently working with Storebrand and Citycon, investigating possibilities for the City Syd site, with adjacent bus terminal.

Several large moves are required to transform Tiller into an urban and sustainable area. Establishing a new bus terminal will be an important step towards a greener mobility, and the location should strengthen the pedestrian and bicycle flow through the development.
Tiller should not compete with Midtbyen, but the large scale and low density in the area allows for a different approach, where Tiller would be an arena for the larger programs and activities that Trondheim has to offer. This project shows a potential for systematic densification of commercial areas, in synergies with other programs – a retrofitting of suburbia.
1. THE TILLER RING
We introduce a local ring road around City Syd and under E6. The system is connected to the main roads in the area and distributes the traffic more evenly.
2. THE TILLER TERMINAL
A new direction to the west is introduced to the area by placing the new terminal along E6, with a passage under. Adjacent to the terminal the new generator Coop Arena is situated, as an extension of City Syd.
3. THE TILLER TRACK
Ivar Lykkes veg is transformed to a car-free street with an EL-train that distributes customers and goods internally in the area. Densification will happen along the street with new entrances and public functions and plazas.
5. THE TILLER PIECES
Each site will consist of a set of pieces: different typologies are applied to densify around existing volumes, to create distinct spaces and streets with a better microclimate. New program creates zones for different programmatic centroids.
4. THE TILLER GRID
We propose that the whole site is organized as a smart-grid, where surplus energy is exchanged between the functions in the project. The mixed-use situation at Tiller is an ideal place for developing such a system, because of the 24-hour activity span. All big box shopping would be covered with solar panels.
In the first step we laminate the existing volumes at City Syd with new retail over and underground. Coop Arena is established at ground floor, the new attraction and generator of the area. Together with the Tiller Terminal and several free standing buildings, towers and lamellas, Coop Arena creates the framework for a new public plaza. The diverse programming, streets and plazas facilitate synergies, flow and activity in the public spaces.
THE ARENA FLOOR
The level of the arena is a large, continuous floor, stretching from the Tiller terminal in the West to the existing pedestrian bridge over Østre Rosten in the East. The floor continues through Coop arena, and becomes an extension of the plaza. It folds down and towards the south, and connects with the park along Sentervegen. All programs around the plaza are extrovert and help activating the space. The arena floor consists of 5 main projects:
1. Coop Arena
2. The Arena Plaza
5. Culture house
Coop Arena has a strong relationship between inside and outside. This is underlined in the projects by flexible walls that can open and close towards the context. The arena is planned as an event-space that could host a variety of different scenarios and activities, from Coop Hypermarked, to Disney on Ice. The flexible walls opens up for the possibility of using the plaza end the arena together, for instance is a ski-sprint with the finishing line inside the arena. The interior of the arena is planned for multiple functions of varying scale and intensity.
