Herdla Birdwatching Tower is situated at the tip of Askøy – a low-lying island in Hordaland county, off Norway's west coast.
The landscape of open grasslands, shallow sea and freshwater ponds makes the area, called Herdla, an important location for migrating and breeding birds, as well as a popular destination for birdwatchers.
由地方保护区管理的当地委员会委托卑尔根本地工作室LJB Architecture and Landscape设计这座滨海观鸟塔楼，主要为人们提供良好的观赏视角。建筑师为游客们设置了一系列的新路径，使游客们拥有更好的观景点。
The local council, which manages the conservation of area, asked Berge's Bergen-based studio LJB Architecture and Landscape to install the tower on a seaside spot that offers good views. It connects with a series of new paths, designed to make the unique landscape more accessible to visitors.
建筑的混凝土基础可以追溯到二战时期，这也有助于降低项目的总体成本。
现存的结构被改造为容纳抽水站，以便于有效控制周边池塘和农田的水位。
The concrete foundations of a structure dating back to the second world war were repurposed as the tower's base, which helped to reduce the overall cost of the project.
This existing structure was adapted to accommodate a pumping station used to control the water level of the surrounding ponds and agricultural land.
考虑到无障碍通道，建筑师设置了一个平缓的斜坡，并通过木材建造了L型通道和座椅区。
斜坡和座椅区的两侧设置有一定高度的木质墙体，这样能够为游客阻挡阵阵海风。
A gentle ramp, which ensures the tower is accessible to wheelchair users, extends in an L-shape around tiered timber seating that creates a compact amphitheatre for tours or presentations.
The ramp and seating area are flanked on the western side by a wall that protects them from the strong sea breezes.
观鸟塔主要通过木材和钢材建造而成，高度为7米。入口区域的形态取决于现有地基。
在建筑内部，一座金属楼梯螺旋上升至圆形观景平台，游客在这里可以坐拥全方位的景观视角。
Built from steel and wood, the tower rises seven metres above its site. The entrance level is a square volume determined by the shape of the existing foundations.
A spiralling metal staircase leads to a higher platform with a circular plan that offers a 360-degree panorama of the surrounding landscape.
“这座建筑将下部安全稳定的基础和上部定向独立观测台相结合。”Berge说。
“精致的木质板材能够很好地适应天气状况，为这个塑性的几何形式创造出柔软、自然的立面效果。”
"The architectural intention was to assemble a safe and stable basement with an aerodynamic and directional independent observatory above it," Berge suggested.
"The precisely mounted wooden cladding adapts and changes colour in response to the weather conditions, creating a soft and nature-like overcoat to the strong and geometrical form."
To help hide visitors from the birds, a circular roof cantilevers above the upper deck, which in turn projects beyond the walls of the level below so both areas are in shade and sheltered from the elements.
