Idesya and Chantehaut: architecture redesigns urban life in Belval

News

At Belval, urban transformation is about more than just building housing.
It's about creating living spaces in their own right, capable of forging links with their environment, respecting the site's industrial history and inventing new uses.

With Idesya and Chantehaut, the architects have risen to this challenge by proposing a strong signature: between light, height and conviviality.

Think neighborhood before building

At the heart of the project: a comprehensive urban approach.

The architects commissioned to design Idesya didn't just draw buildings. They also thought about the urban fabric in which they would fit.

Each building is positioned to maximize natural light, offer unobstructed views and reinforce the impression of space.
At Belval, where density is a constant challenge, this layout work makes all the difference.

Industrial inspiration: between memory and modernity

Belval was born out of Luxembourg's steelmaking past.
The architects of Idesya and Chantehaut have chosen to pay homage to this history through their own choices:

  • Raw materials: use of concrete, metal and glass in their natural expression;
  • Clean, functional lines, without overloading;
  • Simple volumes that emphasize spatial efficiency and transparency.

This industrial inspiration is reflected in an architecture that is both contemporary and respectful of its context.

Chantehaut: elevation as a signature

With Chantehaut, architectural ambition reaches its peak - literally.

At the highest point of the Square Mile, the residence plays with height without ever overwhelming its surroundings.
Its slender lines catch the light and extend the views over the ponds and surrounding hills.

The wrap-around loggias characteristic of the project are more than just balconies. They are designed as protected outdoor rooms, extending the living space while contributing to the rhythm of the facades.

The whole gives the building a slender, light, almost airy appearance - a rare quality in contemporary urban planning.

Priority to light and comfort of use

Behind the form, there is an attention to everyday life.
The architects have multiplied the number of devices to let light in:

  • Full-height picture windows ;
  • Glazed or semi-open loggias;
  • Room layout to favor double orientations.

Thermal and acoustic comfort has also been taken care of, with latest-generation insulating materials combining interior well-being with energy savings.

Idesya and Chantehaut offer open, bright, modular homes that can be adapted to the changing needs of their residents.

A project designed to last

In a sector often marked by economic pressure, the Idesya and Chantehaut architectural project makes a bold choice: to focus on architectural quality as a lever for sustainable value.

A well-designed building looks better for longer, ages better and remains attractive to new generations of buyers and tenants.

The teams of architects and urban planners in charge of the project have taken this gamble on aesthetic and functional sustainability.

Conclusion: giving new meaning to urban living

With Idesya and Chantehaut, architecture is more than just window dressing.
It's at the heart of the project, serving the landscape, the neighborhood and, above all, the quality of life of its residents.

At Belval, these residences embody a new way of imagining the city: open, bright, human.
