Exploring the Wonders of Living Walls and Pillars at Capel Manor College

Last week, I spent four days at Capel Manor College in Enfield attending a professional course dedicated to living walls and living pillars. This experience was not only educational but also deeply inspiring. I stayed in a tiny Airbnb cabin nestled in a lush garden just five minutes by bike from the campus. Waking up surrounded by greenery and cycling through the grounds to class each morning created a peaceful, restorative atmosphere that fueled my creativity.

The campus itself felt like a vast living laboratory rather than a traditional college. With its mature landscapes, extensive gardens, hidden pathways, demonstration areas, and even a small zoo, it offered endless examples of planting design, habitat creation, and ecological thinking. This immersive environment made me eager to learn more and left me wanting to return for further study.

The Campus as a Living Laboratory

Capel Manor College’s campus is a remarkable place where nature and education blend seamlessly. The grounds showcase a wide variety of planting styles and ecological projects that serve as real-world examples for students and visitors alike. Walking through the gardens, you encounter:

• Mature trees and shrubs that provide habitat for local wildlife

• Demonstration spaces featuring different planting techniques and green infrastructure

• Hidden pathways that reveal diverse microhabitats and planting schemes

• A small zoo that supports conservation and education efforts

  
  

This hands-on environment allows students to see how design and ecology interact in practice. It’s one thing to learn theory in a classroom, but seeing living walls and pillars integrated into a landscape brings the concepts to life.

Why I Chose This Course

My recent sculptural research has been moving toward habitat-integrated structures and living surfaces. I wanted to understand how professionals in landscaping and green infrastructure actually build and maintain living wall systems. This course gave me the chance to ground my ideas in practical knowledge rather than assumptions.

The course covered a wide range of topics essential for anyone interested in living walls and pillars:

• Plant selection for different environments

• Differences between shade and sun-facing systems

• Indoor versus outdoor applications

• Evergreen versus perennial planting

• Maintenance requirements and access

• Plant companions and pest management

• Irrigation systems, including open and closed water systems

• Nutrient management and resilience

• Structural suitability and budgeting

• Variety of products and systems available on the market

  

  

  

The Importance of Maintenance in Design

One of the most eye-opening lessons was how much maintenance influences design decisions. I hadn’t fully appreciated the practical challenges involved in keeping living walls healthy and functional. For example:

• Safe access for maintenance is critical. Designers must plan how workers will reach plants for pruning, watering, and pest control without damaging the structure or risking injury.

• Irrigation lines need careful placement to ensure even water distribution and prevent leaks or blockages.

• Plant choice depends heavily on maintenance needs. Some species require frequent attention, while others thrive with minimal care.

• Budgeting must account for ongoing maintenance costs, not just installation.

  
  

These factors shape everything from the structural design to plant selection and system layout.

Practical Plant Selection and System Design

Choosing the right plants for living walls and pillars depends on many factors. The course emphasized matching plants to their environment and system type:

• Sun-facing walls can support sun-loving species like sedums and grasses.

• Shade-facing walls require shade-tolerant plants such as ferns and ivy.

• Indoor systems often use tropical or subtropical plants that thrive in controlled climates.

• Evergreens provide year-round coverage and structure, while perennials add seasonal interest and biodiversity.

  
  

We also learned about plant companions—species that grow well together and support each other’s health. For example, combining nitrogen-fixing plants with others can reduce the need for fertilizers.

Irrigation and Nutrient Management

Watering living walls is a complex task. The course covered different irrigation methods:

• Open water systems allow water to flow freely but require careful drainage management.

• Closed water systems recycle water within the structure, reducing waste but needing more technical setup.

  
  

Nutrient delivery is equally important. Plants in living walls rely on a balanced supply of nutrients, which can be provided through soil amendments or liquid feeds in irrigation water.

Structural Considerations and Budgeting

Living walls and pillars must be structurally sound to support plant weight, soil, and water. The course introduced various systems, from modular panels to felt-based designs. Each has pros and cons depending on:

• Wall material and load-bearing capacity

• Exposure to weather and sunlight

• Access for installation and maintenance

• Cost of materials and labor

  
  

Budgeting realistically for both installation and ongoing care ensures the system remains healthy and attractive over time.

The Creative and Ecological Potential of Living Walls

Living walls and pillars offer more than just aesthetic appeal. They provide habitat for insects and birds, improve air quality, and reduce urban heat. This course helped me see how these systems can be designed to support biodiversity and ecological resilience.

For artists and designers interested in habitat-integrated structures, understanding the practical side of living walls opens new creative possibilities. You can design with plants that support pollinators, create microclimates, and contribute to urban greening efforts.

Final Thoughts

My time at Capel Manor College was a valuable blend of theory, hands-on learning, and inspiration. The campus itself is a unique place that encourages curiosity and ecological thinking. The course gave me a solid foundation in the practical aspects of living walls and pillars, from plant selection to maintenance and budgeting.
