Landscaping in Croydon

Building into
the North Downs.

South Croydon climbs into the North Downs, and its gardens climb with it. Retaining and terracing are the core of the work here — and the ground is chalk, not clay.

What we work with here

01

Town-centre density, inter-war suburbs, hillside plots

Croydon covers a wider range than most boroughs. The centre is dense, with apartment blocks and their balconies and podiums. Addiscombe, Shirley and Selhurst are inter-war and post-war semis on generous, largely level plots with side access. South Croydon, Purley, Sanderstead and Coulsdon climb onto the North Downs, where houses sit on distinctly sloping ground and rear gardens frequently rise or fall several metres across their length. Those hillside plots are where the substantial engineering happens — terracing, retaining structures, steps and drainage designed together.

02

Chalk on the high ground, clay in the valley

The south of the borough sits on the chalk of the North Downs, with clay and other deposits in the lower ground towards the centre and north. Chalk drains well and is stable under load, which makes for good foundations, but it softens badly if left open and wet, so excavations are dug and protected properly rather than left standing through rain. On a slope the combination that matters is gradient plus water: a retaining structure needs drainage behind it and a release path, or hydrostatic pressure will do what the soil alone would not.

03

Retaining structures that are actually designed

The recurring job in the south of the borough is replacing retaining that was never engineered. Anything holding back more than about a metre of ground should be designed rather than assumed, with a foundation matched to the ground conditions, drainage behind the wall, and above certain heights building control involvement. On a sloping site there is also a great deal of material to move, and the site sequence — drainage and retaining first, surfaces afterwards — is what keeps a terraced garden stable. Access is usually reasonable here, which means machinery can help.

Questions we get asked

Croydon, specifically

What does it cost to terrace a sloping Croydon garden?
It depends almost entirely on the retaining, not the paving. The variables are how much height is being held, what the ground is, whether machinery can reach the site, and how much material has to be removed. A modest change of level with a low wall is a different order of work from holding back two metres of hillside, which is a structure requiring design and proper foundations. We survey, establish the levels and set it out in a written quote rather than estimating from a photograph.
Is chalk good ground for a retaining wall?
It is capable ground, with a caveat. Chalk drains well and carries load, which makes for sound foundations. But it softens significantly if it is left open and exposed to rain, so the excavation has to be dug and protected properly rather than opened up and left. And however good the ground, a retaining wall still needs drainage behind it — water pressure, not soil weight, is what pushes most failed walls over.
Can a steeply sloping garden have a level lawn?
Yes, as one terrace among two or three rather than across the whole plot. Cutting a level platform for lawn, held by a retaining wall, works well and gives usable space. Levelling an entire sloping garden to one plane means a much taller wall at the low boundary and moving a great deal of material — expensive, and it usually produces a flat rectangle less interesting than the terraced alternative.
