Changes of Level

 

If there are significant changes of level in the garden, note these down at the survey stage as the new design may have to include certain features to accommodate the gradient. See here for information on how to measure a slope.

A gentle, downwards slope away from the house is often useful, as it facilitates drainage for a patio or lawn next to the house. However, a steeply sloping garden may require the building of retaining walls or terraces.
