Space and layout
Take the time to look at your garden and have a think about its shape and size. Consider different areas like the patio, lawn and any corner nooks that are available. You might want to place different furniture in different areas of the garden, providing plenty of space for guests and allowing you to move around the area throughout the day, following the movement of the sun (or the shade!) and creating lots of variety.
As an example, an arbour is a great way of creating a fresh focal point in a forgotten area of the garden, especially if you plant a climber close by and allow it to trail along the structure, resulting in a seamless segue between furniture and foliage.
You also need to think about how practical the furniture will be when it’s being used. When measuring your garden for a dining table set, think about how much space will be taken up when the seats are placed around it. Will there be enough room for you and your guests to push your seats back or to walk freely around the table?
