De Pit office building

Together with HUB, we are renovating an existing building into the modern office building 'De Pit' to house the support services of Stedelijk Onderwijs in Antwerp.
  • Architect: HUB

  • Client: AG VESPA, AG Stedelijk onderwijs

  • Surface: 6.437 m²

  • Budget: € 10.000.000

  • Timing: 2017 - 2020

  • Status: Executed

  • Advisors: CES (techniques), ABT (stability), Abetec (VC), Atelier Dialect (interior), Daidalos Peutz (acoustics)

The modernist, repetitive 1974 office building has 10 floors: 1 underground, 8 above-ground (type) floors and 1 retreated roof floor. The basement serves mainly as technical space, secondary functions and archives. Parking is provided behind the main building over 3 levels.

Nearly Energy Neutral

The Pit is a BEN building. The energy still needed for heating, ventilation, cooling and hot water is obtained from 130 solar panels. A rainwater tank can collect 50,000 litres of rainwater. This is used to flush the toilets.

  • According to the fire safety RD, the building falls under the high-rise building category. To meet the requirements of the KB and the Antwerp fire brigade, some significant interventions were realised to improve fire safety in the building. For instance, the existing escape stairs were demolished and replaced, and we provided structural modifications in the core.
  • The facade consists of a timber-frame structure clad with aluminium panels.
  • The caretaker's house on the roof was replaced with a new structure made of CLT.
  • During the implementation phase of a renovation project, you have to take into account aspects that were not known during the design phase.

As executive architects, we help the designing architects with all technical and financial issues so that they can fully focus on the design. We also monitor the implementation and ensure that the objectives and plan are always crystal clear for all partners, so that together we can realise our dreams.
