When you picture a serene outdoor space shielded from the wind and watched over by lush greenery, you are likely imagining an enclosed garden. This concept has existed for centuries, evolving from simple protective walls to sophisticated modern designs that blend form and function. Understanding what this space is called and how it works can transform the way you approach landscaping and outdoor living.
The Core Definition: What Is an Enclosed Garden?
At its most fundamental level, an enclosed garden is any landscaped area surrounded by barriers. These barriers serve multiple purposes, including protection from weather, privacy for the residents, and the containment of specific microclimates. The term is a broad category rather than a specific design, meaning it encompasses a variety of styles and structures depending on the materials used and the intent behind the enclosure.
Historical Context and Traditional Names
Historically, the need to protect valuable plants from harsh elements and animals led to the creation of these walled spaces. In medieval European monasteries and estates, the **Hortus Conclusus**, or "closed garden," was a staple feature. This style emphasized order, symmetry, and often featured medicinal herbs and fruit trees within high walls, providing a sanctuary from the outside world.

Walled Gardens and Kitchen Gardens
As agriculture developed, the **walled garden** became a standard feature of large estates and country homes. These structures were typically built from brick or stone to absorb and retain heat, allowing for the cultivation of fruit trees and tender vegetables in cooler climates. Often referred to specifically as a **kitchen garden**, this enclosed space was designed for practicality, placing fresh produce close to the kitchen while keeping it separate from the ornamental areas of the property.
Modern Interpretations and Design Types
In contemporary landscape architecture, the concept has evolved to prioritize aesthetics and lifestyle integration. While walls remain a common feature, the materials and purposes have diversified significantly. Homeowners today often choose specific styles to achieve a desired look or solve environmental challenges.
Corten Steel and Geometric Enclosures
Modern designs frequently utilize materials like corten steel to create sleek, geometric borders. These structures define a garden space with minimalist elegance, offering clean lines and durability. Unlike traditional high walls, these enclosures often sit lower, creating a visual boundary that maintains an open view while preventing encroachment from surrounding lawns or pathways.

Green Walls and Living Enclosures
Perhaps the most popular modern adaptation is the **green wall** or **living wall**. This approach encloses a space not with rigid materials, but with densely planted vegetation. Trellises, pocket planters, or modular grids are used to create a vertical garden that acts as both a barrier and a stunning feature. This type of enclosed garden improves air quality, provides insulation, and brings a vibrant, natural element to urban or suburban settings.
Functionality and Benefits of Enclosure
Choosing to enclose a garden space offers distinct advantages that go beyond aesthetics. The primary benefit is the creation of a controlled environment where plants can thrive regardless of the external weather. Walls and hedges act as windbreaks, reducing evaporation and protecting delicate flowers and vegetables.
Additionally, an enclosed space provides a sense of security and intimacy. It defines a specific territory within a property, allowing for quieter contemplation, outdoor dining, or peaceful reading without the feeling of being exposed. This sense of separation can significantly enhance the usability of an outdoor area.
Planning Your Own Enclosed Space
If you are considering creating your own enclosed garden, the first step is to define your goal. Are you looking to block wind, create privacy, extend the growing season, or simply add visual interest? The answer to this question will dictate your choice of materials and layout.
Whether you opt for high brick walls reminiscent of historic estates, a minimalist steel frame, or a lush vertical garden, the principle remains the same: you are crafting a protected sanctuary. By understanding the various names and methods—from the classic **walled garden** to the modern **green enclosure**—you can make informed decisions that will bring beauty and utility to your outdoor space for years to come.
