the competition

The location referred to as “De Loodsen”, situated on the quay called Piet Heinkade, is part of the large-scale development taking place on the south shore of the IJ river in Amsterdam. This development is characterised by a very high building density and a mixture of residential, working and recreational spaces. In 1999, Stadsontwikkeling Amsterdam (Amsterdam Urban Planning Department) launched a private competition for this location. The architectural firm of Köther Salman Koedijk was invited by the combination of clients involved to work together with them in developing a plan. The collective proposal formulated by the group, referred to as “Homework” and consisting of 290 residential units and 5000 m2 of business space, won first prize. In order to complete the plan, in addition to Köther Salman Koedijk Architects, two other architectural firms were each asked to elaborate a specific part of the overall plan, namely HvdN Architects (towers 3 and 5 and wagon 2) and Wingender Hovenier Architects (towers 1 and 6). Köther Salman Koedijk Architects designed towers 2 and 4, wagon 1, the glass conservatory and the car park; they also supervised the overall architectural concept and the outdoor spaces. The Loodsen complex is located right next to the renovated warehouse complex referred to as “De Zwijger”, in what was formerly the Oostelijk Havengebied (Eastern Port Area) of Amsterdam. The urban planning concept for redeveloping this area is based on the original spatial characteristics of the location: the long lines set out by water basins, quaysides and rails. The area is divided into compartments, with each compartment elaborated differently by a coordinating architect within the framework of the overall concept. The series of buildings alongside the Piet Heinkade form a linear volume bordered on both sides by panoramic open spaces: to the north by the water mass of the IJ harbour and to the south by the Piet Heinkade, designed as an urban esplanade, and the railway tracks. The close proximity to the city centre and the central train station together with the excellent motorway access provided by the IJ tunnel and the Piet Hein tunnel combine to make this location a very attractive one. The point of departure for the urban development plan for this area, referred to as De Loodsen, was to further strengthen the specific character of the location and to make optimum use of the open space available. This was realised via a closed structure of two linear building blocks alongside the waterfront in combination with an open structure of six towers, 35m tall, alongside the Piet Heinkade. The building blocks alongside the waterfront, the so-called “wagons”, are reminiscent of the former harbour sheds and form a link to the series of building volumes on the north side. The open structure on the south side provides space for three squares and allows a great deal of sunlight to penetrate into the residential units. The three squares are linked to each other via two passageways: one parallel to the axis of the building block and the other perpendicular to it.

The synergy between residential space and working space is another central theme of the overall plan. On the ground floor as well as the other floors, living space is combined with and linked to a range of business spaces in various ways. As a result, De Loodsen provides a smooth transition between the big-city business and office buildings to the west and the urban residential blocks to the east. The three squares each have their own specific themes: 路 a tree-filled square; 路 a conservatory with glass roof; 路 a square with a focus on art. The presence of natural elements in close proximity to residential units is an important factor in determining the attractiveness of urban living. The conditions created by Alterra for the tree-themed square on the west and the roof gardens atop the wagons allow for the proper growth and development of flora and fauna. These natural elements are integrated into the urban environment in such a fashion as to improve the quality of the living space without causing any inconvenience or trouble. The artistic duo Kkep has integrated a strikingly attractive artwork with lighting elements into the paving of the art-themed eastern square. The centrally-located third square is roofed over and furnished as a large-scale conservatory for multifunctional use by residents and business users of the office space. The conservatory is strategically situated in the shade to ensure that it never becomes overheated by the sun; it also provides protection from the wind in between the tall buildings. Taken together, the various design elements contribute to creating a cosmopolitan atmosphere with excellent facilities where people can live and work in an attractive and interesting environment. The buildings are also intended to continue providing an attractive environment in the long term. The residential units are therefore flexible in nature and have been designed with a certain amount of overcapacity to ensure that they can be modified to take into account future patterns of living and working. The building structure itself, which contains as few uninterrupted concrete wall elements as possible, provides maximum flexibility with regard to the choice of interior design and layout as well as levels of finish desired. The robust exterior appearance of the buildings and the use of brickwork are reminiscent of the massive warehouses that once stood here. The facades have a neutral character in relation to the various uses made of the interior. As a result, the buildings do not have a specifically residential ambience. This is in harmony with the overall location and provides greater freedom for any future functional modifications that might prove necessary.

wagon 1, tower 2 and 4 KSKA

Köther Salman Koedijk Architects elaborated the designs for towers 2 and 4, wagon 1, the glass conservatory and the car park. The wagons were designed in the form of residential blocks 24m deep with residential units 5.4m wide. By applying corridors as the collective access principle, it was possible to exploit the potential of the location to the fullest. The corridor was made more interesting by providing the uppermost corridor with a glass roof and linking it to the lower corridor with the help of voids, thereby allowing sunlight to penetrate deep into the interior of the building. In connection with the decision regarding the corridor, we designed two intertwining residential units that cross each other above or below the corridor and which we call the X type unit. In this type of residential design the units face towards the north, with a view over the IJ harbour, as well as the south, with a lively and sunlit view. Depending upon the specific location of the X unit inside the building block, several design variations were worked out, including units suitable for combined living and working accommodations. In order to ensure optimum penetration of daylight into the relatively deep residential units, the facade is designed with a relatively thin framework of bricks around large folding and/or sliding windows. These windows can be completely folded away, thereby transforming each indoor space into an outdoor space. All these units also have an ample conservatory on the south side. The ground floor contains flexible and small-scale work units, which are directly accessible from the boulevard or the square. Tower 2 is situated on top of wagon 1, whereas tower 4 is a free standing volume between the art square and the conservatory square. Both towers have four residential units per floor. The use of a column-based building structure ensures maximum functional flexibility. In tower 2, the units are laid out around a central core containing various facilities/functionalities, thereby providing maximum freedom with regard to the layout. The units can even be further combined, so that two units can be integrated to form a larger residential unit, as is the case with the two penthouses on the top floor. These units also have a patio inside, which connects to the roof garden via a staircase. All the residential units have a balcony with a view over the IJ as well as the city. The facades are reminiscent of the industrial architecture of harbour areas. In contrast to the “open” facade design used for the wagon, tower 2 has a more closed structure. The design here is characterised by a subtle interplay of recessed elements within a tight grid combined with alternating vertical windows. Tower 4 stands on top of a high double glass base containing office space. Behind the glass, spectacular structural V columns are visible, linking the grid used for the residential units with the grid of the car park. The facade above the base displays a block pattern with black brickwork combined with light-grey windows. The balconies are staggered, adding an interesting visual touch to the design. The balconies in the North-South passageway, in particular, provide a spectacular and striking visual effect. It is here that the theme of “Close by and far away”, so characteristic of De Loodsen, can be experienced to the fullest.

urban living HVDN

The optimal use of the available open space forms the conceptual core of the project. A collection of open public areas connect a series of towers 35m high. A sequence of narrow passages link large courtyards and it is the contrast between the relatively cramped connections and the openness of the courtyard spaces that illustrate the strength of the scheme. This ensemble creates a compact complex of unexpected vistas towards the harbour, the city and the courtyards themselves. Between them, the projectâ&#x20AC;&#x2122;s three towers contain 124 retail dwellings with 2300m2 commercial space. Within the strict requirements of the brief, the desired objective is the optimum balance between context and programme: urban living with the city to one side and the open harbour to the other. Corner apartments in the first two towers and dwellings that extend the whole depth of the third ensure that this balance of proximity to the city and wide open views is achieved. Each blockâ&#x20AC;&#x2122;s flexible internal layout ensures that both individual requirements and the changing forms of living/working accommodation can be catered for. The facades are articulated in a neutral manner with the repetitive window openings giving little indication of the functions behind. This flexible approach proved its worth during the development phase of the project as, at a late stage, the programme was drastically changed without having serious repercussions for the elevations. Each block is articulated with one single colour and one fenestration technique. Diversity is achieved by considering the development of closely packed blocks as a whole. The projectâ&#x20AC;&#x2122;s robust expression pays homage to the history of the old warehouse buildings still standing on the waterfront.

Two housing blocks at the IJ-Harbour in Amsterdam As in many European cities the 19th and 20th century warehouses along the Oostelijke Handelskade (IJ inner-harbour) in Amsterdam have been abandoned. Some of the existing buildings have been squatted and turned into mix used atelier buildings. Over the past period the area has been developed incorporating the existing warehouses into a strip of high density, mix used facilities (concert hall, hotel, restaurants), ateliers, commercial space and housing between the inner-harbour front and the main road to the new eastern housing districts of Amsterdam (Java-, KNSM-, Borneo- and Sporenburg Island). Halfway along the strip the plan ‘Loodsen’ is an ensemble of six 11-floor high towers and two 5-floor high buildings along the waterside. Three architects have designed the ensemble in close collaboration. The program of the ensemble is 317 apartments, 5.000m2 commercial- and atelier spaces and a two-floor sub terrain-parking garage. The two corner buildings of the ensemble along the roadside contain 85 social housing apartments and commercial space on ground level. The fixed program [2-, 3, - 4, - 5-room apartments and four apartments for handicapped] is considered to be the initial reason for the buildings’ construction but alteration in apartment layout can be anticipated within close future. Since the buildings will be single owned [housing association] they are developed as casco floors. The concrete tunnel form construction and the layout of the central core and shafts are developed to accommodate future changes in number of apartments per floor and layout of the apartments. The buildings therefore typologically closer related to office buildings than traditional housing buildings. The buildings have been developed as independent but closely related pieces within the ensemble. Their positions and volumetric differ, but they are linked by their tectonic expression; the horizontal concrete beams and the plastic expression of the brickwork. The plinth of the ensemble and the ‘second horizon’ of the neighbouring 5 floor high buildings are taken as subtle shifting in the plasticity of the facades. There is no significant difference to front, side and back of the buildings. Programmatic difference or the varying programmes of rooms are not expressed in the facade. In their robust and neutral expression the buildings clearly refer to the neighbouring warehouses, relating them to the atmosphere of this specific part of the city.
