Landscaping in Lewisham

Steep gardens,
made usable.

Forest Hill and Honor Oak are named for their hills, and the gardens prove it. Some of the steepest domestic plots in London are in this borough.

What we work with here

01

Victorian terraces on some very unlevel ground

Brockley, Forest Hill, Honor Oak and Sydenham are largely Victorian and Edwardian terrace and villa, built across ground that climbs sharply from the Ravensbourne valley up towards the Norwood ridge. The result is a borough where a rear garden rising three or four metres over its length is unremarkable, often in one tired bank with failing sleepers or an old brick wall at the bottom. Catford, Hither Green and Lee are flatter and more regular, with inter-war stock on level plots. Brockley has a well-regarded conservation area of Victorian villas.

02

Clay on a gradient — the demanding case

The borough sits on London Clay, and clay on a steep slope is the condition that most reliably exposes bad retaining. Saturated clay is heavy and exerts sustained pressure, so a wall holding it back needs a foundation designed for the ground, drainage behind it so water cannot build up, and a release path through or below it. The great majority of failed garden walls we are asked to replace here failed for the same reason: they were built as decoration with no drainage and no foundation, and hydrostatic pressure pushed them over within a few winters.

03

Getting material off a steep, landlocked site

Terracing generates volume. Cutting platforms into a hillside produces a great deal of spoil, and on a Victorian terrace with no side access every barrow-load leaves through the house and up to a skip on the street with a council permit. On a steep site that is genuinely slow, and it is the largest single variable in the programme. Where machinery can reach the rear the job changes character entirely. We establish the access at survey and price it honestly, because a terracing job quoted as though it were a flat patio will always overrun.

Questions we get asked

Lewisham, specifically

My Forest Hill garden rises steeply from the house. What can be done?
Terrace it into two or three level platforms. That gives you a usable space immediately outside the back doors, a retaining wall that can double as seating or raised planting, and a further level above with an outlook back over the garden. It is a better outcome than trying to level the whole plot, which needs much taller retaining at the boundary and the removal of far more material.
Why does drainage matter so much behind a retaining wall?
Because water, not soil, is what pushes most walls over. Saturated London Clay behind a wall with nowhere to drain builds hydrostatic pressure that acts on the whole face, and it will defeat a structure that would have held the dry soil easily. A wall that lasts has a drainage layer behind it, a land drain at the base and weep holes or an outfall to release water — as important as the foundation and far more often omitted.
How much spoil comes out of a terracing project?
A lot more than people expect — cutting level platforms into a hillside means removing real volume, often many tonnes. On a landlocked Victorian terrace it all leaves by barrow through the house to a skip or grab lorry on the street, which needs a council permit and drives the programme more than the visible work does. Where machinery can reach the rear, the same job takes a fraction of the time.
