Barcelona approves Parc Central de Vallcarca: a 10,000 m² green lung and climate infrastructure

Barcelona has formally signed off on the creation of a sustainable space designed to reclaim an area long marked by permanent construction works. This planned 10,000-square-metre green lung is set to reshape the local landscape, delivering striking ecological gains that reflect truly modern climate infrastructure.

How will the Parc Central de Vallcarca work?

The urban scheme will be developed around the Vallcarca viaduct, tying into key streets across the neighbourhood. Major structural interventions are due to begin in late 2026, driving a meaningful public renewal led by the city council through a substantial financial investment.

The proposal aims to bring an end to the area’s long-standing sense of urban “temporary” planning, replacing it with a welcoming, fully connected public place. To understand what the works involve, it is worth looking at the list below, which gathers the park’s main technical highlights.

• Set budget: The estimated investment is around €8.9 million for full delivery.
• Planned size: The new urban green area will total roughly 10,000 square metres.
• Accessible route: A long pedestrian walkway will run through the site, passing directly beneath the local viaduct.

What are the project’s climate benefits?

The environmental approach is focused on easing the high urban temperatures typically experienced during extended summer periods. A major increase in tree cover will provide improved thermal comfort and restorative shade, significantly reducing the harsh effect of heat radiating from hot tarmac across the traditional urban fabric.

A further key element is rainwater management through innovative permeable surfaces. This design slows rapid run-off during heavy rainfall, holds onto essential moisture, and strengthens urban resilience in the face of the wider global climate emergency.

How are the park’s areas laid out?

The site has been organised into two distinct zones, each with a clear purpose for residents. One part is dedicated to everyday urban social life, with children’s play areas and squares suited to lively outdoor community activities, supporting strong social comfort.

Overcoming the land’s steep gradient

The second major section tackles the area’s pronounced natural slope in an elegant way, using integrated ramps and stairways. This smart connection supports full mobility, allowing visitors to move comfortably between raised platforms while enjoying the preserved views.

In addition, features placed on the higher levels considerably enhance day-to-day use for local visitors. To show how the terrain is being used to its fullest, the detailed list below sets out the main facilities within this humanised space.

• Picnic area installed at the highest part of the structures.
• A space of about 200 square metres dedicated to productive urban allotments.
• A street basketball court, with completion expected in the coming weeks.

What is the investment and construction timetable?

Full delivery has been structured into four separate phases to keep the workflow properly organised. The official budget reaches over €8 million, supported by a significant package of mixed funding intended to secure a definitive urban arrangement for the area.

The council’s plan sets out clear deadlines for major construction over the coming years. The main time targets and approved financial milestones are summarised in the list that follows, which brings together essential points from this official timetable.

• Start of the main works scheduled for late 2026.
• Estimated duration of 18 months to complete the park works in full.
• Full handover of the infrastructure expected by mid 2028.

What other improvements will accompany this transformation?

The changes will not be limited to tree planting and landscaping across the terraces. The plan also includes upgrading important surrounding roads, improving essential service networks, and delivering visible infrastructure modernisation across the affected residential neighbourhood.

Alongside the physical works, the social dimension will be reinforced through parallel development of buildings intended for affordable housing nearby. The municipality has announced specific schemes for accessible rental homes, ensuring the ecological upgrade is matched by robust social inclusion for the valued local community.
