Using pathways through your garden to connect distinctly different areas will enable you to break it up into different spaces, and let visitors move freely from one space to another.
3 STEPS TO CREATING GARDEN SPACE
Define the Spaces
Before you begin you will need to plan what you want. Defining the spaces first will then enable you to benefit from a clear structure. Splitting areas of your garden so that they have different purposes will enable you to create different settings and moods – some might be spacious and relaxing, while others might be cozy and intimate.
Create Pathway Features
The point of a pathway is that it takes you somewhere. This means that you will need to add a feature in each area. Consider what you will find at the end of each path and your reasons for moving there. Choose pavers that encourage a visitor to walk along the pathways and explore.
Incorporate Steps
A change of level will clearly define spaces. You can achieve this with natural garden gradients or you can manufacture them by landscaping. Including a section of raised decking is also a good option that works wonders for creating a dining space.
