Important Benefits of Roof Gardens in London
Benefits of roof gardens extend well beyond the visuals. Join us as we explore how these green retreats can impact our cities.
Green space within cities is now widely recognised as a way to enhance air quality and reduce overall heat. But a lack of space and very high land prices makes it difficult to increase the number of parks and natural spaces. This is where rooftop gardens come into the picture, and become a staple in new development schemes.
Rooftop gardens look stunning, offer unparalleled views and provide an efficient and attractive way to enjoy a quiet retreat in the heart of the city. Such is their significance they have grown to become the defining feature of new developments in London. But beyond the visual impact, there are a variety of other advantages to including them in our cities.
Roof gardens benefit tenants
Rooftop gardens have become a highly desirable feature for city dwellers, in both residential and commercial buildings. They provide an oasis of green in an area where it can otherwise be sparse. They give people a much-desired connection with nature. There are many benefits to having access to green space. From reduced stress levels through to attracting top talent to your offices. We have explored these benefits in greater detail here.
Reports continue to show that access to green space is one the most sought after features of a residential or office move. Such desirability enables building owners to charge premiums for buildings with extensive rooftop landscapes.
Combating the UHI effect
All green spaces, rooftop gardens included, positively affect the Urban Heat Island (UHI) effect.
The UHI concept is based on the increased temperatures found in urban areas. This is because the sun’s rays warm up concrete faster than grass, trees and natural surfaces. With the amount of concrete and other hard surfaces concentrated in urban spaces, the city becomes a hot spot (a heat island) all year round. Look at a heat map of England and you will notice the increased heat around the major cities. This in turn results in increased demand for air conditioners and other cooling technologies.
The effect reduces the more green spaces we incorporate into the city. This is especially as the rooftop garden will be covering what would otherwise be a concrete roof – one of the main culprits of the UHI itself.
Planting improves air quality
It is no secret that the air quality in London is notoriously poor. Rooftop gardens contribute to the reduction and filtering of toxic air particles. Not only through the plants and photosynthesis process, but also by deposition in the growing space.
Of course, a single green roof is not going to make a huge difference on it’s own. But numbers of them across the city, combined with other green spaces, can have a noticeably positive impact.
