Openbare Prijsvraag Kunstfort

Motto:                        A  R  T    S  H  E  D

THE CONCEPT
We start from the premise that visitors can approach the fortress (KUNSTFORT) and/or the shed (KUNSTLOODS) from different directions, and also that they must be free to walk through the area in the order chosen by them, and to decide whether to visit both buildings. This makes it necessary to create a logical connection between the ground level (car park) and the crown of the dike (KUNSTFORT entrance). In order to allow for this, we have opted to construct a bridge from the shed’s 1st floor, in addition to the existing steps in the incline of the dike on the north side.

The requirement to make the entire shed suitable for many different types of exhibitions was the reason to have this take place in an introvert “inner building” and to accommodate all other programme components, namely entrance/cloakroom, reception/desk (2 persons), small cafeteria (10-15 seats), storage room (6m2), 2 toilets, 1 disabled toilet, broom cupboard and boiler room in an extrovert “outer building”.

Situating this on the south side of the shed, and dividing the programme between 2 floors offers the following benefits:
• the rural area surrounding the dwellings on the north side remains unaffected;
• the cafeteria can be located on the 1st floor, providing a nice view all around;
• dispatch can take place, or continue to take place, on the north side and
• it makes sense to combine this part with the bridge.

It goes without saying that toilets are available at all times and the public rooms are accessible for disabled persons. And visiting the cafeteria only is also possible, of course.

THE DESIGN
The “inner building” (shed interior):
In order to make the shed suitable for exhibitions, an inner space will be created by means of the following measures:
• raising the interior height of the ground floor by lowering the floor and extending the steel staircase at the bottom
• installing a thermal shell within the shed by means of a wooden frame with thermal insulation safety glass and an air cushion ceiling made of ETFE foil; the entire shed will remain visible on the inside whilst daylight is allowed to enter through the existing wall and roof openings.
• Cutting back the wooden floor on the first storey on all sides, and keeping the steel façade free, making the shed a single cohesive space inside.
• Replacement of the draw links placed low on the first floor with stability cross struts in the maintenance zone (11), creating a fully-fledged interior height on this floor.
• Rendering the various floor levels accessible with the aid of a platform lift (9)
• Installation of an effective climate control, controlled from the boiler room (07) in the “outer building”.
• The skin of the shed will remain fully intact, with the exception of raising the door opening on the 1st floor on the south side.

The “outer building”
Access to the dike is via the steel bridge (17) at the location where the inner building connects with the outer building. The projecting floor as well as the bridge are supported by a steel zigzag construction, so that the foundation remains outside the dike toe. The bridge support can be re-adjusted at the top of the dike’s incline. A distinction is made between public functions (03, 04 and 18) and support functions (05,06,07, 08, 19, 20 and 21). The public functions and traffic areas are located in transparent glass rooms around a enclosed central space with support functions.

SUSTAINABILITY
In order to make both buildings as energy-neutral as possible, we propose the following:
- the glass façade surfaces to be fitted with BIPV modules 156x156 mm (heat barrier and generation of electric power) at a large number of places.
- the flat roof to be constructed as a “green” roof (delayed drainage of rainwater and heat barrier)
- to work with natural ventilation as much as possible
- to investigate whether the surrounding surface water can be used for cooling purposes in the summer
- if possible, application of a combined heat and power system fed by waste wood for heating and electricity supply.

All materials to be used are sustainable, with a minimum impact on the environment:
- the wooden frame in the steel shed to be made of pine, varnished with a clear varnish (based on water)
- the recessed floor in the steel shed to be clad using the existing cobbles
- the main supporting structure for the annex to be made of steel (can be dismantled/reusable)
- enclosed centre space to be clad in natural greyed Oregon Pine timber (no hardwood / minimum maintenance
- façade eaves and floor edges to be clad with sheet titanium (maintenance-free).
