Meristem Design was instructed by the London Borough of Hillingdon to create a solution to screening off some electrical cabinets at a parade of Shops in the borough.

As our streets evolve and expand, more equipment, often unsightly is needed to be installed on pavements and in public spaces. Not only does this reduce pedestrian space and access, it changes our streetscapes detrimentally.

Meristem Design's solution? A collection of custom-made, powder-coated steel planters with 1m Hedera Helix Ivy screening. As you can see from the before and after pictures, the screens provide instant screening and the planters provide a splash of colour and can have custom graphics installed. The planters, if needed, can be moved to allow engineer access at any time. The solution has hidden the cabinets, added some much-needed greening to the area and will help to improve air quality for pedestrians.

Green screens are perfect for screening all manner of unsightly items, such as; AC units, condenser units, electrical cabinets, feeder pillars, bollards and much more. Get in touch with us today to find out more about our variety of shapes, sizes and species available.

However, the use of green screens isn't just limited to this one project; they are a modern design tool filled with many benefits that are important for tackling different urban design problems. Here, we lay out the many benefits of using green screens in urban design projects:

• Aesthetic Appeal: Unlike the stark appearance of conventional barriers, green screens bring a gentle, natural essence to urban landscapes, turning bland areas into welcoming spaces. Their lush green foliage contrasts beautifully with the often grey urban jungle.

• Customisation: As demonstrated in the case study, green screens can be customised to meet the specific needs of a project. The custom-made, powder-coated steel planters show a great example of the flexibility and aesthetic adaptability of green screens.

• Functional Screening: They serve as perfect shields to hide unsightly urban elements like electrical cabinets, AC units, and other utility installations. The practicality of this solution was well-illustrated in this project.

• Improved Air Quality: The vegetation in green screens acts as a natural filter, trapping dust and absorbing pollutants, which is a significant advantage in pollution-prone urban areas.

• Enhanced Public Spaces: By disguising utilities and reclaiming spaces, green screens contribute to making urban areas more pedestrian-friendly, thus enhancing the usability and accessibility of public spaces.

• Supporting Biodiversity: They can support urban biodiversity by providing habitats for various insects and birds, moving towards more ecologically balanced urban environments.

• Sound Dampening: The foliage can act as a natural sound barrier, contributing to noise reduction in bustling urban areas - a crucial benefit in densely populated cities.

• Low Maintenance: Once established, green screens require relatively low maintenance, making them a cost-effective choice for long-term urban projects.

Frequently Asked Questions (FAQs)

1. What types of plants can be used in green screens?

   Green screens offer a diverse palette for the inclusion of various plant species. The choice of plants can vary depending on the local climate, soil conditions, and the specific requirements of a project. Commonly used plants include ivy, particularly Hedera helix, due to its robust nature and ability to provide dense coverage. Other options could include Clematis, Jasmine, and various climbing roses. Shrubs and small trees can also be utilised in more extensive green screen installations. The choice of plant species can significantly impact the look, maintenance requirements, and functionality of the green screen. It's advisable to work with horticulturists or landscape architects to select the most suitable plants for a specific green screen project, ensuring they will thrive in the given conditions and meet the project's aesthetic and functional goals.

2. How do green screens contribute to improving air quality?

   Green screens act as natural air purifiers. The foliage can capture dust, pollutants and absorb harmful gases from the air. Plants in green screens process carbon dioxide and release oxygen, improving the air quality around them. Additionally, they can absorb other harmful pollutants like sulfur dioxide and carbon monoxide. The larger leaf surface area available in green screens provides more opportunity for air purification, making them an effective tool for combating urban air pollution. By acting as a living filter, green screens contribute towards creating healthier, more breathable urban environments.

3. Can green screens be customised to match the surrounding architecture?

   Yes, green screens can be tailored to complement the surrounding architecture. They offer a level of aesthetic adaptability that allows them to blend seamlessly with different architectural styles. The design of the supporting structure, the choice of plant species, and the overall layout can be customised to match or contrast with the architectural features of the surrounding buildings. Moreover, green screens can be designed to follow the form of the architecture, either by mirroring its lines or by providing a natural contrast, thus enhancing the visual appeal of the urban space.

4. What is the maintenance regime for a green screen installation?

   The maintenance regime for a green screen installation typically includes regular watering, fertilising, pruning, and pest and disease management. It's crucial to ensure that the plants receive adequate water, especially during the establishment period and in dry spells. Fertilising will help to keep the plants healthy and vigorous. Pruning is necessary to maintain the desired shape and density of the green screen and to remove dead or diseased growth. Regular inspections for pests and diseases will enable early detection and treatment, ensuring the longevity and aesthetic appeal of the green screen. The specific maintenance requirements can vary depending on the plant species used and local conditions.

5. How do green screens compare to traditional fencing solutions?

   Green screens and traditional fencing solutions serve different purposes but can overlap in functionality. While traditional fences are primarily designed for privacy and security, green screens also offer these features but add aesthetic value, environmental benefits like improved air quality, and support for local biodiversity. Green screens are visually pleasing, creating a softer, more natural boundary compared to the often stark appearance of traditional fencing.

6. Can green screens support local biodiversity? How?

   Green screens can significantly support local biodiversity. They provide habitats for various insects, birds, and sometimes small mammals. The vegetation in green screens can serve as food sources, nesting sites, and shelter for different species. By creating a more varied and natural environment within urban areas, green screens can help to support a broader range of local wildlife, promoting a healthier ecosystem. Over time, a well-maintained green screen can become a mini-ecosystem of its own, contributing to the ecological balance in urban environments.
