Group 2 66 converted into residential houses, however it is not allowed in the row next to the city along the river. Some are art galleries, cafes, restaurants and boutiques. Trondheim’s warehouses were generally made as a combination of wood frames and log structures allowing the creation of many different space distributions. Most of the buildings contain small and low rooms in the lower levels and very large and high spaces in the upper levels. New buildings are frequently built using concrete instead of wood because these buildings have improved fire performance. Sometimes, the concrete is covered with wood to simulate the old structures. However, the use of the original building material is neglected and can somehow affect the cultural and aesthetic values of the houses. For example, the facades are often retrofitted using aluminium windows, while the original were built using wood. The preservation and retrofitting of these traditional buildings should be always conducted using compatible and reversible materials and interventions. Furthermore, climate change (CC) can also affect the landscape and the structural integrity of the warehouses. In 1816 there was a sand slide upriver, which caused the Nidelva River to be shallow, causing the rise of the water to occur in a more important way. With CC the sea can rise up to 3.4 mm per year and this can strongly affect the warehouses. [TRONDHEIM LANDSCAPE AND NIDAROS CATHEDRAL] Trondheim is well known for its wooden built environment with traces back to the Middle Age. In more recent times much of the traditional wooden houses are being replaced by architecture structures made of brick, concrete and steel, creating a more heterogeneous typology with variations in scale, volume and heights. Moreover, the cultural and historical aspect of the landscape also includes the urban fabric with its green areas, gardens and parks and also how the tangible and intangible dimensions are perceived. The natural landscape is integrated into the city centre of Trondheim in such a way that the urban and the natural landscape interact with each other for the development of the city. Moreover, the historic city is integrated by natural elements such as the Nidelva River, the Trondheim Fjord, the coastal area, the valley and the hills surrounding the city. Trondheim developed in medieval times, from the bank to the mouth of the river Nidelva. However, in 1681, almost the entire city was destroyed by a strong fire, which allowed the creation of a new city plan, thus proposing larger streets and building two-storey homes. However, until the 19th century, it was still a village of low-rise wooden dwellings. In 1841 and 1842 two fires left large parts of the city in ashes and the use of wood as main construction material was banned in 1845. However, before this legislation was implemented, the citizens managed to reconstruct the city using wood. With the implementation of the new legislation, a new architectural style based on brick was introduced. Later on, the use of concrete and steel gradually changed the performance of some parts of the city center into a more diverse and complex urban landscape (i.e. new materials were introduced, and the new typology opened up for buildings in several stories, creating a brand-new
