During London Climate Action Week, we visited the King’s Cross area and came away inspired. For such a central, high-traffic part of the city, it felt surprisingly calm. Pockets of greenery tucked between office buildings, several water features, and an abundance of outdoor seating created a space that encouraged people to linger, breathe, and connect. It reminded us of the power of good urban regeneration– not only for environmental and economic benefits, but also for mental well-being.
Thoughtful design decisions can promote calm, social cohesion, and resilience. Below, we explore five interventions that can make a real difference in urban regeneration projects across Europe.
Green Spaces and Biodiversity (Even Small Ones)
Even modest green interventions can have a significant impact. The World Health Organisation highlights how urban greenery reduces stress, anxiety, and depression.
In Berlin, a large-scale study by the University of Hamburg found that life satisfaction increased significantly when green space made up at least 11% of the surrounding one-kilometre radius. Alongside this, Berlin launched a €1.5 million urban wildflower meadow initiative in 2021, aiming to sow and nurture over 50 such meadows across the city over five years. These small meadows, integrated into parks and roadside verges, support biodiversity while offering visually attractive and calming experiences for residents.
Research from Heidelberg University also shows that small green spaces — such as lawns, flowerbeds and tree clusters — can activate emotional regulation centres in the brain and improve overall well-being. These findings reinforce the mental health value of accessible, local greenery, even when it’s embedded in dense cityscapes. Berlin’s Urban Nature Pact further supports this approach, embedding biodiversity goals into city planning and encouraging the transformation of underused spaces into habitats that benefit both people and pollinators.
At King’s Cross, over 40% of the site is dedicated to the public realm, including ten parks and squares and 20 new streets. Tree-lined walkways and planting schemes with native species create moments of calm and ecological value.
Access to Water (Blue Spaces)
Water features have a distinct positive effect on mental well-being. Research from the University of Exeter shows that people living near blue spaces report higher levels of happiness and lower psychological distress.
The Regent’s Canal plays a central role in the King’s Cross redevelopment, framed by walkways, steps, and areas for reflection. But it’s not the only water element in the area. Pancras Square includes a series of narrow water channels running between the office buildings, adding movement and sound to the space. Granary Square’s fountains – made up of over 1,000 choreographed jets – provide a playful, interactive feature that draws children, families and office workers alike, enhancing sociability and joy.
Similarly, Berlin’s extensive canal network offers numerous seating areas along the waterways, creating calm, inviting spots for reflection and social connection amid the urban bustle. These canal-side pockets, often enhanced by soft landscaping and natural planting, serve as quiet refuges that reduce noise and stress while encouraging community engagement.
Other European cities are following suit: in Düsseldorf and Cologne, studies found that proximity to canals and fountains enhanced emotional reflection, social bonding, and physical activity.
Communal outdoor spaces
Communal outdoor spaces are essential for fostering social cohesion, reducing stress, and enhancing overall well-being. Research consistently supports their positive impact on mental health.
The King’s Cross redevelopment exemplifies how integrating communal outdoor spaces into urban regeneration can enhance the well-being of office workers. These areas provide employees with spaces to relax, socialise, and recharge during the workday. In a post-occupancy study of the development, the King’s Cross Central Limited Partnership found that 65% of surveyed office workers said the abundance of outdoor space improved their overall job satisfaction, with many citing the ability to take breaks outside, socialise informally, and attend free cultural events during the day.
Another European example is Berlin’s Potsdamer Platz, which underwent major urban regeneration in the 1990s and 2000s. As part of the redesign, open courtyards and semi-public plazas were created between commercial buildings to encourage both casual and programmed use. While originally criticised for being underutilised, a recent push to improve these spaces with movable seating, greenery, and food pop-ups has increased footfall and dwell time. A 2023 survey by the Berlin Senate Department for Urban Development reported that over 70% of respondents who work in the area now consider the communal areas important to their sense of well-being at work.
Pedestrian-First Design and Connectivity
Car-free zones and walkable routes are vital to mental well-being. They reduce air and noise pollution, promote movement, and make public spaces more inviting and safer.
At King’s Cross, new pedestrian bridges, reconnected streets and wide, tree-lined walkways make it easy to move between home, work and leisure spaces on foot. These physical connections also help foster social interaction and improve access to nature.
A UK study across 22 cities found that more walkable neighbourhoods were associated with lower blood pressure and a reduced risk of hypertension, even when controlling for other lifestyle factors. This supports a broader evidence base showing that walkable places are less stressful, more sociable, and more conducive to everyday physical activity.
A long-standing European example is Munich’s pedestrianisation of the city centre around Marienplatz. Since the early 1970s, the city has expanded its car-free zones to create a welcoming public realm. These interventions have boosted local retail and tourism while making the area noticeably calmer and more liveable for office workers, visitors, and residents alike.
Urban Rewilding and Everyday Nature
Small-scale or ‘micro’ interventions can be just as powerful as large parks. Green roofs, pocket parks, and planted verges all support mental health by offering daily contact with nature. Even having a view of greenery from a window has been shown to reduce stress and improve concentration.
The “Cities Dare Wilderness” project in Frankfurt, Hannover, and Dessau-Roßlau from 2016-2021 aimed to let nature reclaim areas of the city. Wild grasses, flower meadows and unmanaged plots were left to evolve naturally, boosting biodiversity and creating surprising urban oases that improve mood and relaxation.
During the lockdown in 2020, many cities found surprising rewilding results as nature began to reclaim spaces. In Barcelona, the effect was so evident that the city decided to embrace more natural processes, allowing weeds to grow and installing bat and bird boxes, insect houses and beehives. Barcelona’s Nature Plan 2030 is now underway, with goals including naturalisation, promoting biodiversity and improving citizens’ access to urban nature.
Expanding green spaces is just the start. Once we have more nature, bringing the insects and birds, next we can reintroduce further species to ecologically complete the spaces. This reconnects people to nature further, offering them the chance to see, hear and connect with wildlife.
Why This Matters
Good urban regeneration doesn’t just improve land values or infrastructure; it improves lives. By integrating evidence-backed interventions that support mental health, developers and investors can create spaces that are not only sustainable but also joyful, calming, and deeply human.
As consultants, we encourage our clients to design and deliver schemes that incorporate these principles, ensuring long-term value for residents, communities, and investors.
