THE BUILDING - WATERDOG ARCHITECTS - GREGORY NIJS, KLAARCHITECTUUR LOCATION - SINT-TRUIDEN, BELGIUM AREA - 300 m2 PROJECT YEAR - 2016 The building we have been analyzing is situated in the centre of Sint-Truiden, Belgium. It has a rather long history – it was built in the 16th century. Due to the original oak-wood roof construction and archway with corner stones the building is presumed to have been a barn. Afterwards it was re-built into a chapel. Vaulted ceilings above the choir, decorative columns, arched windows, fresco drawings are remains from those days. In the 20th century the chapel was converted into an arts academy, then became a court and, finally, rehearsal place for drama club. The last 50 years before the reconstruction the chapel has not been occupied. The building is listed as a historical monument. This means that architects had to meet several criteria. For example, the historical character of the building had to be kept intact. Thus, the building has a long history of hosting other than religious functions. However, the chapel was left abandoned and “Klaarchitectuur” architects felt like its unique atmosphere would suit their office. Therefore, it has been decided to transform it into a workplace where past, present and future would meet.

PART A 1. DESIGN - CONCEPT The architects felt the need to preserve as much of the unique character that the chapel had as possible. Thus, the building remained untouched, despite it being affected by the ravages of time. It was decided to design a new construction that would contrast with the existing one. Another important thing was to reopen the historical monument to the public. For so many years a chapel was very important for the community so the architects felt the need to give it back to the city. By stacking boxes on top of each other independent units have been created which made it possible to have both public and private functions at the same time. The movement in the renovated building is designed as a spiral wrapping around the boxes. Visitors are taking a walk exploring the structure where a few separate office spaces, terraces meet. The inside of the chapel acts as the outside for the office boxes, being non-insulated.

OLD STRUCTURE

NEW STRUCTURE

On the ground floor public area as well as bathrooms, storage room are situated. There is also a shower that makes it possible to reorganize the place for an overnight stay. First and second floors host office function and private terraces. Third floor is designated for a meeting space. It extends


through the roof. This way the intervention becomes visible from the outside. Moreover, more daylight and views of the city are being achieved. It was very important for the architects to achieve a high quality working environment. They descibe their own office as a ‘spiritual experience’ and are proud of the dynamism they have achieved.

2. BUILDING STRUCTURE Stacked boxes form a stand-alone construction. They are not attached to the walls or roof of the chapel. The only way this stacking technique could have been achieved is by having double flooring. This means that boxes are actually stacked on top of each other, they are not intersecting. Building structure is executed in white plasterboard to achieve a sculptural look. . 3. CONSTRUCTION SYSTEM The structure of the existing chapel building was intact. Although they were cracks and minor issues but it has been repaired and the spread of the damage has been avoided. Original oak roof structure has been preserved too. However, lacquered steel was used to strengthen them. The architecture language used keeps the new and the old easily distinguishable. Roof was fully replaced as it was too damaged to be kept. A foundation of titanium micropoles was used to hold the new construction. They are 40 feet deep into the ground. In order to achieve a stacked box structure that is separate from the existing building steel structure was chosen. Also, all the building parts had to be small enough to be able to be brought through the main doors so that influenced design decisions. Even the floors of the stacked boxes are made from folded steel plates, with OSB and parquet on top. For the insulation rock wool was chosen, it was all wrapped in plasterboard. Thus, steel structure is completely hidden. Only white plastered walls, forming a sculpture, are visible.

4. MATERIAL USE Existing chapel walls remained untouched. Even the original floor tiles were kept. During the renovation there were dismantled in order to install the heating and new foundations. Afterwards all the good tiles were placed back. Stacked boxes are made out of white plasterboard. That makes them easy to distinguish from the old structure, create a sculpture-like effect. Stairs that are spiraling around the boxes are contrasting, they are black. This way the shape of the boxes stands out better. The staircase leading to the first floor is completely attached to the structure of the white boxes. It is creating an illusion of a freely floating element. All the stairs are made from lasered plates of steel that is coated in a powder. Stairs can be closed off by a steel door to achieve the privacy. This way two functions can be separated. The two other stairs are made of two stair flanks in lasered steel, with one placed higher than the other so it serves as a railing at the same time. Steps are manufactured from dubble powdercoated folded steel. In the former choir of the chapel there is a kitchen island. It is designed out of MDF, sprayed in brass. There is also a cross-shaped tabernacle that adds to the building’s liturgical character. Brass details are carrying through the whole building. Brass taps were picked for the bathrooms.

STRUCTURAL SCHEME OF THE BUILDING


THE DETAIL We were interested in analysing extruded box detail. It is the top box in the whole structure that extends through the roof to the inner courtyard. Conceptually it interested us as it is the biggest change architects decided to make to the outside of the building. Also, it is one of the most important elements regarding the function of the building - it is a meeting room where clients are being invited for the discussions. Thus, it is one of the key elements of the building, it affects the image of the whole company. Moreover, we got an opportunity to analyze something that connects inside and outside, new structure with the existing walls. Therefore, we have focused on the details of: 1. How the roof of the extruded box meets the roof of the chapel; . 2. How the wall of the extruded box meets its roof; 3. How the boxes are stacked, walls and other elements are attached inside the builduing. The analysis of the third detail was taken the furthest, it has been turned into a detail of a circular building and constructed. The existing detail consists of: 1. Existing roof structure - wooden beam; 2. Steel I beam structure; 3. Z profile beam, steel profile sheet; 4. Supportive structure - OSB board; 5. Existing roof structure – wooden beam; 6. Plaster board; 7. Insulation – rockwool; 8. Glass wall; 9. Floor finishing – parquet; 10. Wall finishing - plaster

PART B 1. DESIGN - CONCEPT Some of the architects design intentions turned out to be circular, the use of steel plates in order to strengthen the roof beams, they have also replaced the original floor tiles. However, they have replaced a window and doors into metal profile ones. This could have been done using wood profiles. Our aim for the redesigning stage was to follow the architect’s approach and keep the heritage chapel untouched, this way the history is preserved for the future generations. The modern part of the building had to go through quite a few changes. Although the concept of the building stayed the same – we followed the idea of white boxes stacked on top of each other – The steel building structure was retained in our intervention, yet the layers of the planes (floors and walls) were replaced with circular elements. 2. BUILDING STRUCTURE The steel beams/columns are retained, they are holding stacked boxes as the structure needs to be very strong and compact to be able to fit into existing chapel. Also, steel beams can be reused. However, most of the other metal parts have been replaced. • ‘Z’ profile steel beams that were holding roof and floor structure have been changed into wood ‘I’ beams. • Steel profile sheets were replaced by wooden counter beams, Instead of metal studs we could use timber studs. Moreover, in their project architects used plasterboard. Our intervention uses a more sustainable material, namely OSB boards. Instead of plastering OSB boards with regular cladding materials or chemical plaster we are proposing to use lime plaster. Lime plaster is composed of lime, sand, water. A porous, textural material lets the building breathe. It helps to stabilize the humidity by absorbing and releasing moisture. It is also very durable and its finish provides aesthetic texture. Rockwool was changed into straw insulation panels. Straw insulation panels are made of extruded wheat straw surrounded on all sides by recycled paper. They provide good humidity regulation as well as insulate sound. That was very important for a building that is hosting two different – private and public – functions. It is also good for keeping a stable temperature. They store heat, provide smaller temperature fluctuations during the summer. 3. CONSTRUCTION SYSTEM The original steel structure of the building aims to be retained, as steel is a reusable material and classifies in its circularity.

DIAGRAM OF THE REDESIGNED BUILDING


4. MATERIAL USE Redesigning building we used much more natural materials than it was done before. Although the metal structure – steel beams – was kept, some of the metal beams, steel profile sheets were changed into wooden alternatives. Insulation in the whole building has been changed into straw insulation panels. Instead of plasterboard we have decided to use OSB boards. Originally architects used metal frame to hold the walls together. This has been replaced to wooden frames. Walls are plastered with natural, lime plaster. Not only metal structural elements but also metal decor details were changed into natural ones. One of the most important accents in the building were steel stairs. It has been decided to replace them to the wooden ones.

THE DETAIL During the investigation of the detail we have realized that architects did not prioritize sustainable, circular materials. We have came up with a solutions for that by replacing: 1. Z profile steel beam to wood beams; 2. Steel profile sheet to wooden counter beams; 3. Metal studs to timber studs; 4. Plasterboard to OSB boards; 5. Plastering to lime plaster; 6. Rockwool to straw insulation panel. Some parts of the detail, for example, steel beams were kept. However, they can be reused.
