Progetto in primo piano: appartamenti ACA a Utrecht-Overvecht

Fondato nel 2014 da Karin Dorrepaal e Saskia Oranje, DOOR architecten è lo studio di architettura dietro la ristrutturazione e la rivitalizzazione di 362 abitazioni a Utrecht-Overvecht. Anche EQUITONE ha svolto un ruolo importante nel progetto. L'architetto e ingegnere strutturale Terry Pater si è occupato del progetto insieme a Karin. Terry ci parla della filosofia alla base del progetto e della scelta dei pannelli di facciata EQUITONE.

Housing corporation Mitros is the client for the entire project, comprising a total of 1,800 residential units. The 362 homes of the ACA flat (ACA stands for Apollo, Centaurus and Atlasdreef) made up the first phase, which has now been delivered. Phase 2, the CJ Dreven project, will start in a few weeks. For ACA, DOOR architecten worked with Over Morgen (a provider of sustainability, energy and installation advice), principal contractor Hemubo and KCP, which together with Hemubo is responsible for liaising with the residents.

Terry Pater: "For the ACA flats, we started with a meticulously designed sustainable basis – the chassis, so to speak. That chassis will be the same for all 1,800 residential units in the project. We devoted a lot of time and energy into the engineering of this chassis, and it shows. The result delivers a high RC value, good airtightness and a strong architectural statement. On top of this chassis, of course, comes the bodywork – the cladding. This differs per project and ensures a completely different look for the various sub-projects, while retaining certain similarities.

The ACA flats will have a robust, stylish looking façade. We have chosen Eternit as the supplier for the façade panels, because with the EQUITONE ranges Linea, Tectiva and Materia, Eternit offers a wide range of options in terms of colour combinations, of smooth and rough surfaces, shading, mutual contrasts, etc. The effect of the sun makes the building look very different at different times, which is a nice aesthetic plus."


In their approach, DOOR architecten often emphasise the circular aspect. "That doesn't mean that we only carry out circular projects," says Terry Pater, "but they do make up the majority of our work. If we receive non-circular assignments, we will always inform the client about the sustainable options that we can offer. It's simply in our DNA. The ACA project received an honourable mention in the Dutch Betonprijs (Concrete Award) in the 'circular' category, on account of the reuse of the existing concrete shell. In other words, the existing concrete did not have to be demolished, removed and then re-produced and rebuilt. We also reduced the ecological footprint, by minimising the cutting and sawing losses on the façade elements."
