Sunken gardens don't need to be grand affairs, simply lowering a section of your garden can offer some seclusion and give you a whole new perspective. If you're thinking of building one in to your own garden design, it's worth taking a little time to consider what you want your sunken garden to achieve.  Here we've listed five key elements to think about when planning a sunken garden and the best places to visit for design inspiration. 

 

Five design elements to consider when planning a sunken garden

 

1. Drainage
Bear in mind that by digging a hole you are inviting all the rainwater to gather in one place. Many sunken gardens boast ponds on the lower level for exactly this purpose. It is worth taking advise from a landscaper before you start digging downwards, to avoid disappointment later on.

2. Walls
The walls surrounding your sunken space need to be robust because they have to hold back a considerable weight of soil. This is obviously dependant on how far you dig down but whatever depth you decide upon, it is a design element worth thinking about.

3. Seating
Having excavated, the obvious thing to do is make some sort of seating area so you can enjoy your new bolt hole. This is where your personal style can come in to its own. Choose elegant, comfortable seating for an intimate sunken terrace or go for a more rustic look and choose a simple arrangement using chunks of logs gathered around a fire pit. Which brings me to the next point...

4. Fires
Fire pits are trendy and great for garden parties but if you get its position wrong, the outcome can be disastrous. The smoke has annoying habit of blowing all over the place, running the risk of sending guests home with streaming eyes. If you want to install a fire pit in your sunken garden, take careful notice of prevailing winds or rig up some sort of chimney.

5. Don't over think it
Not everybody has the skill, desire or resources to create something dramatic and theatrical, so if you're after something a bit less convoluted then a similar effect can be achieved by simply lowering a patch of lawn and surrounding it with deep and gorgeous borders. This not only affords you the pleasure of a slightly secluded refuge but gives you a different view of the plants. It is exciting to be able to see things from a slightly alternative angle.
