What problems come up in London gardens?
Most London gardens share a few difficulties, and a design should deal with them rather than hide them.
Clay soil and standing water
Heavy clay drains slowly. Lawns and beds can sit wet for weeks in winter, then bake hard and crack in summer. Plants that cope with both, raised beds and sensible falls on paving all help.
Shade and overlooking
High walls, neighbouring trees and the north-facing rear gardens common in terraces create deep shade. Planting needs to suit it. Screening, trellis and layered planting can also make an overlooked garden feel private.
Levels and access
Many terraced gardens sit above or below the house floor, with steps and short retaining walls. Carrying materials through the house is common, which shapes what can be built and how.
Trees
If a tree is protected by a Tree Preservation Order, or sits in a conservation area, you normally need to tell the council before pruning or removing it. A design should work around mature trees where it can.
