The new city hall in Deventer unites the old historical city hall with a new city office. The new building complex is located at the ‘Grote Kerkhof’ and extends as far as the ‘Burseplein’. The 24.000 m2 large project consists of 20.000 m2 new buildings and 4.000 m2 renovation and restoration of existing listed monuments. The project consists of an entrance building with a main building behind it and unites all of Deventer’s employees, formerly divided over the city, under one new roof. It houses the city council and all municipal services and invigorates a formerly forgotten part of the inner city.
COURTS AND SQUARES
The City Hall’s design seamlessly blends in with Deventer’s typical urban tradition of gardens and squares that are interconnected via alleys, lanes, pathways and gates. The building is organized around two new public squares: an open court surrounding the former mayor’s residence and a covered inner square; the building’s central hall where citizens, visitors and employees can meet one another. Adjacent to the office buildings in the Polstraat and Assenstraat two large city gardens are situated next to the neighbouring residential buildings.

At ground floor level the building creates a link between the city’s two most important squares through a new continuous route that starts at the ‘Grote Kerkhof’, continues via the open Mayor’s Court and covered central hall to the Burseplein and ends at the main ‘Brink’ square. Perpendicular to this passage is a second walking route that connects the inner city with the IJssel river shore. Both are public routes. At the first level a closed circuit has been made for City Hall staff and employees connecting all historical buildings with the new ones. This route lies around the Mayor’s Court and enables a fast connection between all functions and departments.

BUILDING AND ENVIRONMENT
位于Grote Kerkhof前侧的建筑共两层。该部分建筑拥有斜面的屋顶和垂直线条清晰的建筑立面，与其周边的de Hereeniging社区建筑和老市政厅建筑如出一辙。这种建筑环境的连续性让新建筑与老街区轻松衔接。后移的建筑屋顶不仅为建筑创造了全新的户外平台，还提高了建筑在Grote Kerkhof广场的辨识度。
The front building at the ‘Grote Kerkhof’ consists of two layers with a sloped roof and a facade composition with strong vertical lines, like its neighbouring buildings ‘de Hereeniging’ and the old city hall. This continuity makes the front building effortlessly fit in with its historical surroundings. By placing the roof backwards a city balcony is created. This makes the facade appear more separated, creating a recognizable facade at the ‘Grote Kerkhof’.
The main building consists of three layers, like most buildings surrounding it. The tall vertical windows blend in with the architecture of the inner city and allow daylight to cast deep into the building, together with the skylight of the large hall. The main building has a roof surface consisting of alternating mansard roofs and green flat roofs, creating a skyline similar to its environment. The mansard roofs create spacious interiors in the attics. The roof terrace alongside the Mayor’s Court offers a panoramic view over Deventer’s inner city.

FACADES AND ART
开放的木雕框架和闭合的砖砌空间交替出现在建筑立面上。石砌立面由带有凸面窗框的大体量体块组成。多彩的砖块打造了生机勃勃的立面效果。雕刻的立面组成了不同尺寸的橡木框架，它们共同围合成具有当代艺术特性的建筑外貌。设计师与当地艺术家Loes ten Anscher合作，将一系列由铝制成的指纹形象装点在橡木框架中，2264个指纹来自于代芬特尔的2264位市民。这些指纹散布在建筑的内外立面上，形成了巨大的艺术作品。独特的指纹装饰让市政厅真正化身为“市民之家”。
Open filigree wooden frames and closed brick volumes alternate within the facades. The stone facades consist of large block masonry with protruding window frames. The bricks are multi-coloured creating a lively image. The filigree facades consist of a grid of different sized oak wood frames. The oak framework provides space to integrate contemporary art in the building’s architecture. In collaboration with local artist Loes ten Anscher a series of aluminium grids was designed to fit within the oak framework, containing 2.264 unique fingerprints of 2.264 different citizens of Deventer. Spread out over the outer and inner facades of the building they form one large work of art. The visible presence of Deventer citizens in the facade turns the city hall into a true ‘Citizen House’.

MATERIALS AND DETAILS
The city hall contains both public and private spaces that have received their own materialisation and detailing. Robust materials and sober details characterize the public spaces. The anthracite coloured natural stone floor leads the visitor from the different main and side entrances over the ground floor to all public spaces such as the central hall and the Mayor’s Court. The walls, stairs, columns and panelled ceilings are made out of concrete and finished with solid oak frames and fillings. The oak filigree facade with aluminium fingerprints is continued from the street to the interiors surrounding the court and central hall, making the interior part of the outer public space. The confined spaces are mainly situated in the main building and contain the city’s offices and back offices. Concrete and solid oak are used in combination with soft white and grey tones in the interior and furniture.

The Deventer City Hall is one the most sustainable public/government buildings in the Netherlands. Thanks to a clever design with tall spaces, vast amounts of daylight and air, optimized use of as many natural sources as possible, the implementation of green and multiple technical sustainable measures.
The great amount of windows, roof lights and high ceilings allow natural light to enter the building everywhere, creating an agreeable working environment and simultaneously lowering the electricity consumption. The exposed concrete inside the building contributes to a high-quality, comfortable indoor environment: the concrete stores warmth or cold in various seasons. Concrete core conditioning is also used. The shed roof construction in the public hall prevents direct sunlight from entering and overheating the building. Ventilation ducts and grids in the windows and floors let fresh air seep into the building. By transporting this heated air out of the building via the atrium, surplus heat is used in an efficient way. The use of sunlight, rainwater and water from the IJssel river (for cooling and heating) increases the building’s sustainability with 25% as opposed to similar offices in the Netherlands. The City Hall received the Dutch sustainable GPR score of 8 to 9 as well as the international qualification BREEAM ‘Excellent’.
