Landscaping in Twickenham
Landscaping is the structural half of the garden: the retaining walls, the levels, the drainage, the sub-bases and the surfaces everything else sits on. Done properly it is invisible; done badly it is the reason a two-year-old terrace is already moving.
Twickenham (TW1) sits in South West London and is characterised by Victorian terraces, 1930s semis and riverside developments, with generous rear gardens that suit side-return infills and full-width rear extensions.
That context shapes how we approach landscaping here. Parking suspensions and skip permits are usually straightforward, and many properties have side or rear access that speeds up muck-away and material handling. We survey the property, confirm the consents that apply to TW1 and issue a fixed price against a written scope, so the figure you sign is the figure you pay unless you change the brief.
Our indicative rate for landscaping in South West London is around £410 per m², reflecting a ×1.08 area factor against our London baseline. Use the instant quotation tool for a figure tailored to your size, specification and start date.

How the job runs
Survey
Levels, soil, drainage and boundary conditions recorded before design.
Design
A levels and drainage strategy, retaining structure design where needed, and a materials schedule.
Enabling works
Clearance, grubbing out, waste removal and access protection.
Structures and drainage
Retaining walls, steps, drainage runs and sub-bases installed and compacted.
Surfaces
Paving, edging and pathways laid to falls with correct joints.
Soft works
Topsoil, planting, turf and a maintenance handover.
Retaining walls are structures, not decoration
Any wall retaining more than about 600mm of soil is holding back a significant load, made worse by water pressure behind it. We design retaining structures with the right foundation, reinforcement and — critically — drainage behind the wall, so hydrostatic pressure does not build up and push it over.
Sleeper walls, blockwork with facing, gabions and reinforced concrete each suit different heights and budgets. Where a wall retains a neighbour's ground it becomes a party matter and is treated accordingly.

Landscaping in Twickenham: common questions
How much does landscaping cost?
Our indicative rate is around £380 per m² plus a base cost for site set-up, varying with levels, retaining structures and surface choice.
Do I need permission for a retaining wall?
Walls over 2m high, or over 1m adjacent to a highway, need planning permission. Retaining a neighbour's ground may also engage the Party Wall Act.
How long does a landscaping project take?
A modest garden is 2–4 weeks. Significant level changes, retaining structures and drainage take 6–10 weeks.
Can you fix a garden that floods?
Usually yes. We diagnose whether it is falls, compaction, a blocked or absent soakaway or a high water table, then design the fix rather than just re-laying the same surface.
