Platform on new construction, renovation, restoration and transformation
Recently, a lot of work has been done to renovate Het Christelijk Lyceum Zeist. After the renovation of the non-monumental parts, it is now the turn of the 1920 main building. In phase 3 of the construction, Groothuis Bouwgroep is renovating the monumental building, while preserving its character and using architectural interventions appropriate to today's requirements.
The monumental building section is some 5,100 m2 in size and is being improved both structurally and climatically. Groothuis Bouwgroep is carrying out the structural work in this phase. “On the inside, the exterior walls will receive an insulated pre-wall. Monumental window frames will remain, but the old windows will be dismantled and replaced with new double-glazed windows with a better insulation value. Then everything will be repainted. Inside, floors and ceilings will be renewed on the first floor and second floor,” explains project leader Leon Teunissen.
On the second floor, the emphasis is on the roof. That will be insulated from the inside. There will also be an additional intended to create more classroom space. For daylight, a skylight will be incorporated into the roof. An existing classroom will be refurbished with a new floor and a new ceiling. In addition, the stairwell will be modified and additional walls will be added. Teunissen: “It will be completely fresh and tidy again. And the school will regain some of its comfort. It will soon be able to withstand another twenty years.”
Working in an existing building requires many checks. “We work with a 3D model, but it is always a question of whether it is completely correct. It's a very old building, with little pieces being added on all the time. Only after demolition do you know how it really is. And that is sometimes quite a challenge.” A lot of switching, short lines of communication and adjusting plans: that is Groothuis Bouwgroep's working method in these kinds of situations. “For example, we encountered unexpected leaks and wood rot. One challenge is bigger than the other. But so far we have managed to solve everything,” said Teunissen. With detailed drawing work and scans, the construction team is now ensuring that the building does appear completely correct on the construction drawings. “That saves a lot of hassle in
the future.”
The renovation is happening while education continues. That requires tight coordination, especially with demolition and work on the roof. Teunissen: “Soon the exams will start and then you don't want students to be bothered by our construction.”
In February, the construction team completed the left side of the building. A start will soon be made on the right side. “That's largely a repeat of the left side, but a little more complicated. There also have to be new structures on the roof for the heat pump, among other things.” Teunissen is looking forward to the result. “It really will be a building that meets all the requirements of today, but with the characteristic appearance that belongs to the monument. A beautiful old building that will soon look super sleek again. For our construction team, it's very nice to contribute to that.”
