The premises of Jan De Nul s.a., one of the world’s biggest dredging companies and among Belgium’s most important civil and industrial construction firms, have been located in Aalst, alongside the river Dendre, since 1938.
Following the company’s significant development, a first office building was added to the industrial complex in 2005. The huge workshops and the offices are now occupied by 750 people.
Since 2011, the company is once again critically short of office space for its employees. After a first project started in 2011 (abandoned in 2017, after the building permit premises was granted) and the purchase of several neighbouring plots, a new project is being developed in 2019.
While continuing its industrial activities, the project involves restructuring all of the office buildings dating from before 2005, demolishing the company’s historic building and replacing it with a new corner building, and creating a brand new building on the neighbouring land alongside the river Dendre, from the other side of the Kammenstraat to the Consciencestraat.
The corner building will mainly house meeting rooms.
The new building will have eight above-ground floors (new entrance hall, 165-seat auditorium, company restaurant and new office space) and three underground levels of parking for 440 cars. The new building will be connected to the corner building by a six-level walkway over the Kammenstraat.
The lengthways positioning of the land, the size of the first office building and the aim of limiting the shadows cast onto neighbouring houses all led to the comb-like configuration of the new buildings and the terraced layout of the floors.
The Owner would like a calm and measured architecture to act as a counterpoint to its industrial might around the world. For this reason, the first project involving a large sphere was not chosen.
Four spaces, with a coat similar to that of the first extension in 2005, are placed on two levels high base comprising the collective premises. The first level above ground has a very large terrace and an open ground garden. The roofs are planted.
The ventilated double facade has motorized interior blinds, which provide sun protection and an abundant and deep distribution of light in office floors. The exterior curtain wall is fitted with extra-clear glazing, reflective glazing and steel grating.
The facade of the old office buildings located along the Kammenstraat gets a new insulated rendering and aluminum window frames. The long baseboard made of polished and perforated stainless steel sheeting (covering the car parks of the 2005 building) continues on the base of these buildings.
The upper roofs, which are provided with a layer of photovoltaic panels and a closed-circuit geothermal installation, partially ensure the energy independence of the building.
The Owner will be carrying out the works itself.
