Reuse of existing buildings
Reuse of existing buildings is more urgent now than ever! It provides opportunities to reduce the environmental impact of building substantially and to preserve cultural heritage. Fortunately, we see an increasing shift in the appreciation of existing buildings and materials, partly due to rising prices for raw materials, supplies and energy. Unoccupied buildings and changed user needs require more adaptivity. We use our broad expertise and experience to guide clients through renovations or transformations to future-proof buildings.

Using research in design
To renovate and/or repurpose a building is a knowledge-intensive task. At an early stage, we need to evaluate the qualities and performance of an existing building and its elements. We use our knowledge of materials, construction techniques and processes. While respecting the monument, we like to design appropriate sustainability interventions with an eye for detail, desired comfort and use. Through a correct approach, the potential of the existing building can be optimally utilised and balanced with your ambitions. We call this approach ‘Using research in design’.
Multidisciplinary teamwork
Within the existing built environment, multidisciplinary teamwork is crucial. Especially in unique projects with a high technical profile or buildings with a monumental status. By research, analysis, calculating power, creativity and cooperation, we can develop concepts and solutions from various perspectives and put them into practice. We gladly seek cooperation with project team partners including architects.
Methods and instruments
We use various in-house developed methods and instruments for our advice. These include our quick scan, which provides a fast and methodical insight into the opportunities, possibilities and consequences for retrofitting and sustainability. With the aid of our circularity tool, we map out which elements in an existing building have the potential for reuse. The EIM tool calculates the environmental impact of our designs so that we can steer towards sustainable solutions. Where necessary, we will apply BIM models in a broad manner, from visualisation to operation.
