Crusch Alba by Gus Wüstemann

For the renovation of his apartment in the historic Gotico area of Barcelona, architect Gus Wüstemann has installed a white, intersecting bathroom and kitchen in the shape of a cross.

The crusch alba (white cross) helps to provide illumination to the rear of the apartment where natural light is limited.

The kitchen fittings are hidden from view behind cabinets and the bath can be folded away to provide a lounge area in one of the children's bedrooms.

Large sliding doors allow the rooms around the white cross to be individual bedrooms or extensions of the same living space.

The original, uneven condition of the stone walls, plastering and ceiling have been retained and protected by a layer of varnish.

crusch alba (white cross), Barcelona 2009

The Project is our flat in Barcelona in the Gotico area, in the center of the historic part of Barcelona.

A challenge was the very heterogenic floor plan, which was interrupted by various light patios.

The other issue is little daylight in the old town of Barcelona, as the sun and the heat were considered rather a burden in the old times. There is one major façade facing the street banys nous, with big windows and balconies.

It was clear that we will have a big living space in this area. For the connection, organization (circulation) and lighting up the back part of the apartment we had to come up with an invention.

Crossing two programs = the white cross

The invention is to cross two programs:  the kitchen and the bathroom, two brightly light up white spaces, forming a white cross.

The white cross we put between those medieval walls and created a bright center in the middle of these fragment spaces and light patios.

As the crusch alba (white cross) is a cross of two programs, there is no circulation, no matter where, you are either in the kitchen or in the bathroom.

The rest of the space, the walls and ceilings are left in it’s original state, raw stone walls, wall paintings and raw plaster finishes.

Intervention of layers - pictures of the old times

We implemented the white cross as a new volume in the existing space and created openings into this white space. We light up the periphery. the border between old an new.

In that respect, the layer outside of the white cross becomes the outer space, generating pictures of ‘the old times’ like looking outside a window into another landscape. By coincidence, real windows appear in these openings.

We left all the old surfaces in the original state, just varnished them: painted ceilings, painted wallpapers, raw old stone walls of the Gotico and even raw plaster of the new building interventions.

The overlay of layers of old and new with light in between emphasizes the lack of hierarchy of old and new. It’s the feeling of not finishing, keeping it urban and letting the process and time be visible that gives a feeling of freedom.

Space Machine – the spaces are not defined by walls floors or volumes

The apartment can be used as loft or as a three bedroom apartment. The white cross is physically and visually the center core of the back part of the apartment.

The actual bedrooms and the bathroom can be divided by big sliding doors and are not defined by the cross itself. So the master bedroom space is part of in the white cross and part of the remaining old space (old layers). So the actual rooms are urban spaces, as they are part of various elements.

There is a major structural wall separating the living area from the white cross and the private areas of the apartment. Two door size openings and a window to a light patio are the only connection to the living area, dividing the flat in two parts.

We dissolved the original wall into a sequence of elements, so that the openings become in between spaces of things touching rather than holes in wall. So the separating element becomes the connecting element, an attractor brought to life by light.

As there are numerous options of how many bedrooms and niches we can create as bedrooms, the kids have foldable mattresses, so they can choose where they want to sleep. The kids are ‘camping’ in the apartment, no fix bedroom.

urban space – horizon of light

The wooden volumes we implemented on top of the old structure, the historical stone structure of the Gotico. Between the old layer and the new implementation there is always a horizon of light, expanding the space where normally it is the end of a room (periphery, where walls and floor meet).

By creating the wooden objects we have no ‘floor surface’ but are walking on a wooden volume, there are no defined surfaces like walls and floors, but urban elements and volumes that we can use freely.

Program free architecture

As usual we implemented our tool of ‘program free architecture’, so the kitchen is not visible, but is part of the white cross. The children’s lounge in the bedroom is actually a bath, if you take off the top.

The main bathroom is hidden by a huge sliding wall and only appears when you need it, the shower is in a corner of the white cross.

If a space is not used for a specific program, it always available as living space or for what you want it to be.

The flat is like an continuation of the urban space of the Gotico of Barcelona, with some space machine, the white cross, added on.
