Project
A new standard for green living in Brussels
Utopia makes Ukkel even greener—both literally and figuratively. The project creates an oxygen-rich, green sanctuary that enhances its surroundings. What’s more, its carefully designed energy concept ensures that fossil fuels are completely eliminated in Utopia.
The result is a unique living environment where a minimal ecological footprint goes hand in hand with maximum living comfort. This location demonstrates that true luxury lies in serenity.
Utopia comprises several architecturally contemporary and elegant residences, organically integrated within a beautifully landscaped park. This deliberate choice to keep the scale small creates a unique environment with a village-like character.
Each apartment is finished to an exceptional standard, using sustainable, high-quality materials that complement the green surroundings.

The philosophy behind Utopia is simple: a green environment is the foundation for superior living comfort. As such, a clear decision was made to prioritise open space, so that more than 70% of the site now consists of open, landscaped ground.
Here, 91 new mature trees will have the space to develop into a thriving natural ecosystem. This green canopy promotes biodiversity, supports natural water filtration and provides welcome shade during the summer months.
A key role is reserved for the wadis: cleverly designed basins that collect rainwater and allow it to gradually seep into the ground.
These natural drainage basins are not only ecologically essential, but also provide a safe habitat for birds, insects and small mammals.
At a time of rising energy costs and an increasing need to reduce our ecological footprint, residential energy supply is a critical concern. After all, a future-ready home requires a future-proof energy system.
That is why Utopia eliminates the need for fossil fuels entirely. Energy is supplied through a smart collective system combining geothermal energy (ground-source heat) with solar panels, providing warmth in winter and passive cooling in summer.
The result is a comfortable home that is fully prepared for the future.
ABOUT CORES DEVELOPMENT
Since 2006, CORES Development has been committed to urban core reinforcement in cities and municipalities. The CORES ‘Urban Landscapes’ respond to the current and future needs of the market. Only in this way can sustainable and innovative real estate be realized.
From that vision, CORES Development explicitly profiles itself as a concept developer rather than a traditional project developer — an approach that has also recently been recognized with multiple awards.
